How Many Sets of Textiles Should a Hotel Have? How to Calculate Par Stock

When opening a new hotel, one of the most frequently asked questions in textile purchasing is this:

“How many sets of sheets and towels should we buy per room?”

At first glance it looks like a simple question.

If there are 20 rooms, 20 sets?

40 sets?

60 sets?

One of the answers commonly used in hotels is:

“Buy 3 par of textiles.”

This can be a useful reference to start with.

But in professional textile planning it is not enough on its own.

Because the textile needs of two 20-room hotels can be completely different from each other.

The first hotel has its own laundry and can have textiles ready for reuse within a few hours.

The second works with an external laundry company, and dirty textiles come back only the next day or later.

One hotel operates year-round at 50–60% occupancy.

The other is full all the time in season.

In one hotel every room has two pillows.

In another there are four pillows.

One hotel changes towels daily at a high rate.

In another, because of a sustainability policy, towel changes are managed on guest request.

So the right question is not:

“How many par should we buy?”

but:

“How many of each textile product do we need on hand for our operation to run without interruption?”

In this article we will look, from an investor's and operator's perspective, at what the Par Stock system in hotels is, the concepts of 1 Par, 2 Par, 3 Par, and 4 Par, and how sheet, duvet cover, pillowcase, towel, and bathrobe stocks can be calculated.

First, the Basic Concept: What Is Par Stock?

Par Stock refers to the standard stock level of a specific product that a hotel needs to have on hand to keep its operation running.

For textiles, in its simplest form:

1 Par = The amount of textiles needed to fully prepare all of the hotel's rooms once.

Let's consider, for example, a 20-room hotel.

If one sheet is needed for each room:

20 rooms × 1 sheet = 20 sheets

For this product:

1 Par = 20 units

Yet the hotel does not only need the textiles that are in the rooms.

At the same time, some textiles may be:

• in use in the rooms,
• being washed in the laundry,
• waiting in the housekeeping store,
• in clean stock,
• collected in dirty stock.

That is why running the hotel's operation with only 1 Par of textiles is, in most cases, extremely risky.

What Do 1 Par, 2 Par, 3 Par, and 4 Par Mean?

Let's work through a simple 20-room hotel.

Let's assume one sheet is used in each room.

However, this table is only a mathematical starting point.

What matters is how these stocks are distributed within the operation.

What Does 1 Par Mean?

In a 1 Par system, there are only enough textiles to prepare all the rooms once.

20 rooms:

20 sheets

When the hotel is fully booked, all the sheets are in the rooms.

The next day, while the rooms are being cleaned, the dirty sheets have to be washed.

But there is no clean spare.

If the laundry is delayed, operations can stop.

If a sheet gets stained, there is no replacement.

If a product tears, there is no replacement.

That is why:

1 Par shows the theoretical room need; it does not show an adequate operating stock for most hotels.

What Does 2 Par Mean?

In a 2 Par system, theoretically:

1 Par in the rooms + 1 Par in the exchange/laundry cycle

may be on hand.

In a 20-room hotel:

20 × 2 = 40 sheets

This system can work in some businesses with fast laundry operations.

But the safety margin is still limited.

A laundry delay, high occupancy, or unexpected attrition can strain operations.

What Does 3 Par Mean?

It is one of the models commonly used in hospitality.

The simplified logic:

1 Par in the room + 1 Par in the laundry + 1 Par in clean stock

can be thought of this way.

For 20 rooms:

20 × 3 = 60 room sets

This model gives operations more room to move.

But the critical point here is this:

3 Par is not a universal rule of hospitality.

Every business should do its calculation according to its own laundry and operating model.

What Does 4 Par Mean?

Some hotels may need a higher safety stock.

For example:

20 rooms × 4 Par = 80 room sets

4 Par can be considered in businesses that:

• have long laundry turnaround times,
• use an external laundry,
• operate at high occupancy,
• find resupply difficult during the season,
• want to keep a high operational safety margin.

But more stock is not always better.

Because excess textiles mean:

• more investment,
• more storage space,
• more tied-up capital,
• more stock control.

The aim is not maximum stock:

It is the right stock.

The Biggest Mistake: Saying “Number of Rooms × 3” and Calling the Calculation Done

Say you have a 40-room hotel.

On a 3 Par basis:

40 × 3 = 120

you have done the calculation.

This gives you only a general reference of 120 room sets.

But a purchase order cannot be prepared with this.

Because how many products are there in one room set?

In one room there might be:

• 1 sheet,
• 1 duvet cover,
• 4 pillowcases,
• 2 bath towels,
• 2 hand/face towels,
• 1 bath mat,
• 2 bathrobes.

So every SKU, that is, every product, must be calculated separately.

The Basic Formula for the Par Stock Calculation

In its simplest form:

Total Need = Number of Rooms × Units of Product per Room × Target Par

For example:

40 rooms,

1 sheet per room,

3 Par:

40 × 1 × 3 = 120 sheets

But if four pillowcases are used per room:

40 × 4 × 3 = 480 pillowcases

If the same hotel has two bath towels:

40 × 2 × 3 = 240 bath towels

So in the same hotel, the quantities of all textile products will differ from one another.

Example: Textile Calculation for a 20-Room Boutique Hotel

Let's consider a 20-room boutique hotel.

Let's assume each room as standard uses:

• 1 sheet,
• 1 duvet cover,
• 4 pillowcases,
• 2 bath towels,
• 2 hand/face towels,
• 1 bath mat,
• 2 bathrobes.

The theoretical calculation on a 3 Par basis:

This table is much closer to a real purchasing plan.

But it is still not complete.

Because now safety stock has to come into play.

Why Is Safety Stock Necessary?

Hotel operations do not work like theoretical math.

Textiles can:

• get stained,
• tear,
• go missing,
• be taken by guests,
• get damaged in the laundry,
• be sent to the wrong room,
• fall below the usage standard.

The laundry company may also be late.

Occupancy may be higher than expected.

The supplier may not deliver the order on time.

That is why, besides the target par stock, Spare Stock, meaning backup/safety stock, can be held for certain products.

The Difference Between Operational Stock and Spare Stock

It helps to think of textile stock in two separate parts.

Operational Stock

The textiles needed for normal daily operations.

For example:

120 sheets.

Spare Stock

The reserve held for unexpected losses outside normal operations.

For example:

10 additional sheets.

Total:

120 + 10 = 130 units

The figures here are examples.

Each hotel's safety stock should be set according to its own conditions.

The Real Formula Should Be a Bit More Advanced

A more useful formula:

Total Textile Need = (Number of Rooms × Units per Room × Target Par) + Safety Stock

For example:

40 rooms,

1 sheet per room,

3 Par,

10 units of safety stock:

40 × 1 × 3 = 120

120 + 10 = 130 sheets

The starting stock:

130 units

could be the result.

So How Is the Target Par Determined?

This is the real question.

When setting the par number, evaluate at least these factors:

1. Number of rooms
2. Expected occupancy
3. Laundry system
4. Laundry turnaround time
5. Housekeeping working model
6. Textile change policy
7. Seasonal intensity
8. Storage capacity
9. Supply lead time
10. Attrition rate

Now let's go through them one by one.

1. Number of Rooms

Naturally it is the basic variable.

But it is not enough on its own.

The stock-management flexibility of a 20-room hotel and a 200-room hotel is not the same.

In a small hotel, even the loss of a few items can have a larger effect within the total stock.

2. Occupancy Rate

Even if annual average occupancy is 50%, planning a hotel's textile stock only for average occupancy is risky.

Because at certain times the hotel may be:

100% full

Textile stock must be able to withstand peak operations in particular.

That is why:

Textile stock should be tested not only against the average day but also against the busy day.

3. Laundry System

It is one of the most important variables.

There are two basic models.

In-House Laundry

Textiles are washed within the same property.

Advantages:

• faster turnaround,
• more control,
• shorter cycle.

In some businesses this can allow operating with a lower par.

External Laundry

Textiles are sent to an outside laundry.

Here there is a time for:

• collection,
• transport,
• washing,
• drying,
• ironing,
• packaging,
• return delivery.

The longer the turnaround, the more textiles remain outside the system.

That is why the par requirement can rise.

4. Laundry Turnaround Time

Consider these two hotels.

Hotel A

Dirty textiles are washed in the morning.

They can be reused the same afternoon.

Hotel B

Dirty textiles are collected today.

They come back two days later.

Even if the two hotels have the same number of rooms, their textile needs are not the same.

That is why one of the basic questions of the par stock calculation should be:

In how many hours or days do dirty textiles become clean stock again?

5. Housekeeping Operations

How housekeeping uses the textiles also matters.

For example:

• are there floor stores?
• is there a central linen room?
• when is clean linen distributed?
• when is dirty linen collected?
• how much stock is kept on room carts?
• is there a reserve for the night shift?

Stock is not only in the warehouse.

It is spread across different points in the operation.

So a stock calculation made without understanding the physical flow of textiles is incomplete.

6. Textile Change Policy

The change frequency is not the same for every textile.

For example:

• bed textiles in a checkout room,
• sheets in a stayover room,
• towels,
• bathrobes,
• pool towels

can have different usage cycles.

Guest behavior also affects consumption.

Towel use in particular may not be fixed per room.

That is why actual daily consumption should be measured over time.

7. Seasonal Hotels

Textile planning has particular importance in seasonal businesses.

Because once the season begins:

• occupancy can be very high,
• the purchasing team's room to maneuver may shrink,
• finding the same product quickly may get harder,
• supply lead times may lengthen.

So at the season opening, not only the theoretical operating stock but also the attrition and replenishment needs that may arise during the season should be considered.

8. Storage Capacity

More textiles provide security.

But they require physical space.

Storage space is extremely valuable in small boutique hotels in particular.

Buying 4–5 Par of textiles and then having nowhere to put them is not good stock management either.

So the stock level should be set within the balance of:

Operational Security + Storage Capacity + Tied-Up Capital

9. Supply Lead Time

How many days does your standard product take to arrive from the supplier?

3 days?

3 weeks?

Is it custom-made?

Is a logo being applied?

Is it imported?

Is there a minimum order quantity?

Can the same product be found mid-season?

As the supply lead time lengthens, the importance of safety stock increases.

10. Attrition Rate

After the hotel opens, track real data.

For example:

Bath towels at start of month: 200

Newly purchased: 20

Usable stock at end of month: 205

Theoretical loss/attrition:

200 + 20 − 205 = 15 units

Investigate why those 15 towels went missing.

• permanent stain?
• tearing?
• lost in the laundry?
• guest?
• counting error?

Over time this data lets you set the safety stock far more accurately.

Are Par Stock and Opening Stock the Same Thing?

Not exactly.

Par Stock is the stock level you want to maintain during operations.

Opening Stock is the initial stock that must be purchased so that the hotel can start operations on opening day.

When building the Opening Stock, the following should be evaluated together:

• target par,
• safety stock,
• opening occupancy,
• laundry readiness,
• supply risk.

Because a new hotel has no operating data yet, estimates are used at first.

After the hotel starts operating, the system is revised based on real data.

Should Par Stock Stay Fixed?

No.

Par stock is a living operating standard.

For example, 3 Par may have been planned when the hotel opened.

Six months later the data may show that:

• the laundry is working very fast,
• attrition is very low,
• stock is more than necessary.

In that case the stock level can be re-evaluated.

The reverse can also happen.

If you constantly run into textile shortages at 3 Par, then perhaps:

• laundry turnaround is long,
• attrition is high,
• housekeeping distribution is wrong,
• real usage is higher than estimated.

The solution here should not automatically be:

“Let's buy more textiles.”

The cause must be found first.

Important: A Par Stock Problem Is Sometimes Not a Purchasing Problem

Even when the hotel has enough textiles, housekeeping may constantly say:

“There are no towels.”

Why?

Because the towels may be:

• waiting in the laundry,
• in the wrong store,
• overstocked on the floor carts,
• uncollected from dirty rooms,
• miscounted by the counting system,
• returned incomplete from the external laundry.

So:

Do not confuse a stock shortage with a stock flow problem.

Before buying more, examine the movement of textiles within the hotel.

Linen Flow — The Journey of Textiles Within the Hotel

In professional textile management, the product's cycle must be traceable.

Clean Main Store → Floor / Housekeeping Store → Housekeeping Cart → Guest Room → Dirty Linen Collection → Dirty Linen Area → Laundry → Quality Control → Clean Linen → Main Store

If a bottleneck forms at any point in this chain, a stock problem can appear.

How Is Par Stock Calculated for Sheets?

Example:

30 rooms.

Per room:

1 sheet

Target:

3 Par

Calculation:

30 × 1 × 3 = 90 sheets

If we use a 10% example safety stock:

90 × 10% = 9

Total:

99 sheets

The practical purchase quantity might be rounded to, for example, 100 units depending on the business's packaging and supply conditions.

The 10% here is only an example.

Every business's safety stock does not have to be the same.

How Is Par Stock Calculated for Pillowcases?

30 rooms.

In each room:

4 pillows

For each pillow:

1 case

3 Par:

30 × 4 × 3 = 360 pillowcases

For example, with 40 units of safety stock:

360 + 40 = 400 units

As you can see, even with 30 rooms, the pillowcase need can reach hundreds of units.

That is why the “room set” approach alone is not enough.

How Is Par Stock Calculated for Bath Towels?

30 rooms.

In each room:

2 bath towels

3 Par:

30 × 2 × 3 = 180 bath towels

For example, with 20 units of safety stock:

180 + 20 = 200 units

However, towel attrition can differ from sheet attrition.

So it may be more correct to evaluate safety stock by product.

How Is Par Stock Calculated for Bathrobes?

The same logic can be used for bathrobes.

30 rooms.

Per room:

2 bathrobes

3 Par:

30 × 2 × 3 = 180 bathrobes

But here the question to ask right away is:

Do we really need 3 Par of bathrobes?

Perhaps bathrobes are used:

• only in suite rooms,
• only on request,
• only by spa guests.

So it is not right to automatically apply the same par value to every product.

Should the Same Par Apply to All Textiles?

No.

This is an important point.

For example:

This table is only an example to show the logic.

The real figures should be set according to the business's operations.

The key principle is this:

Par stock should be thought of by product as much as possible, not hotel-wide.

Calculating Pool Towels from the Number of Rooms Can Be Wrong

Consumption of pool towels differs from room textiles.

For example, a 20-room hotel can have 40 guests.

But the same guest may use more than one pool towel during the day.

Some guests may not use one at all.

So in the pool towel calculation, more meaningful variables can be:

• maximum number of guests,
• daily use,
• exchange frequency,
• pool operating hours,
• laundry turnaround.

That is why pool textiles should be managed as a separate stock category.

If You Have King and Twin Rooms, Separate the Calculation

In a hotel, all beds may not be the same.

For example, there may be:

20 King rooms
10 Twin rooms

In a King room:

1 large sheet

In a Twin room:

2 separate sheets

If these are used, a single “30 rooms” calculation gives the wrong result.

King:

20 × 1 × 3 = 60 King sheets

Twin:

10 × 2 × 3 = 60 Twin sheets

The total number of physical sheets could be:

120 units

But these are not the same SKU.

They should be tracked separately in the warehouse.

Do Not Forget Extra Beds and Baby Cots

If the hotel offers:

• extra beds,
• sofa beds,
• baby cots,

their textiles must be calculated separately too.

Otherwise, with everything else in the room ready, a suitable sheet for the extra bed may not be found.

This small-looking omission can create a big problem in the guest experience.

Example: Detailed Textile Plan for a 40-Room Hotel

Let's now do a more comprehensive example.

Hotel

40 rooms

Standard room textiles

• 1 sheet
• 1 duvet cover
• 4 pillowcases
• 2 bath towels
• 2 hand/face towels
• 1 bath mat
• 2 bathrobes

Target

3 Par

Theoretical operating stock:

Now let's add example safety stock:

This is now a much more useful table for preparing a purchasing budget.

But let's stress again that the spare quantities here are only examples.

How Is the Textile Budget Calculated?

Once the quantities are set, the budget becomes easy.

Formula:

Total Product Budget = Quantity to Purchase × Unit Price

For example:

130 sheets × 500 TL:

65,000 TL

260 bath towels × 350 TL:

91,000 TL

can be calculated like this.

When the same exercise is done for all products, the Opening Linen Budget emerges.

That is why par stock is not only a housekeeping matter.

It directly affects the investment budget.

The Cost of Excess Par Stock

Raising the par level increases security.

But it ties up capital.

For example:

40 rooms.

Sheet unit price:

500 TL.

3 Par

40 × 3 = 120 units

120 × 500 = 60,000 TL

4 Par

40 × 4 = 160 units

160 × 500 = 80,000 TL

The difference in sheets alone:

20,000 TL

When you think of the same difference across:

• duvet covers,
• pillowcases,
• towels,
• bath mats,
• bathrobes,

one extra Par can reach a serious investment amount.

So:

The “Let's buy extra just in case” approach is not professional stock management either.

The Hidden Cost of Too Little Par Stock

At the other extreme there is very little stock.

In that case, costs such as:

• emergency laundry,
• overtime,
• express transport,
• last-minute textile purchases,
• using products of different quality,
• housekeeping delays

can arise.

In the worst case, because there is no clean linen, a room may not be ready for sale on time.

For a hotel, the cost of that is far higher than the cost of a sheet.

What Is the Ideal Par Stock?

There is no single right number.

The ideal par stock is:

A stock level high enough to keep operations running without interruption, and low enough not to tie up unnecessary capital and storage space.

To determine it, the following equation can be used:

Room Need + Laundry Cycle + Operations Cycle + Safety Stock = Target Stock

That is why par stock is less a purchasing decision than an operations design decision.

How Should Par Stock Be Managed After the Hotel Opens?

The first purchase is only the beginning.

Regular counts should follow.

For example, a monthly textile report:

This table shows purchasing needs early.

Reorder Point — When Should We Place a New Order?

When textile stock drops to a critical level, placing an order may be too late.

Especially when the supply lead time is long, it helps to set a Reorder Point.

The simple logic:

Reorder Point = Expected Consumption During Lead Time + Safety Stock

For example, for a particular textile:

• average monthly attrition: 10 units,
• supply lead time: 2 months,
• safety stock: 10 units

then:

10 × 2 + 10 = 30 units

As the remaining room to maneuver approaches this level, reorder planning may come onto the agenda.

The real system should be set up according to the business's consumption and supply model.

Which Columns Should the Par Stock Table Have?

In a practical working file:

a structure like this can be used.

The aim is not to answer:

“How many towels do we have?”

but to be able to answer:

“Is our current towel stock sufficient for our operating model?”

8 Decision Gates for Par Stock

Before finalizing the textile purchase quantity, answer these eight questions.

Decision Gate 1 — Room Standard

How many of each textile will be in each room?

Decision Gate 2 — Room Types

Do King, Twin, Suite, and other room types use different textiles?

Decision Gate 3 — Laundry

Where will the textiles be washed?

Decision Gate 4 — Turnaround Time

In how many hours/days do dirty textiles become usable again?

Decision Gate 5 — Peak Occupancy

Can the system run at 100% occupancy?

Decision Gate 6 — Attrition

How much safety stock is needed for loss and damage?

Decision Gate 7 — Supply

How quickly can we re-buy a depleted product?

Decision Gate 8 — Storage and Capital

Is there enough space and budget for the planned stock?

Before these eight questions are answered, saying:

“3 Par is enough.”

may be premature.

Do a 90-Day Review After Opening

In a new hotel, the initial par stock calculation is based on estimates.

A re-evaluation after the first 90 days of real operation is very valuable.

Look at:

Occupancy

Is it as we predicted?

Laundry turnaround

Is it within the time we planned?

Attrition

Is it higher than expected?

Housekeeping

Are they experiencing textile shortages?

Excess stock

Are some products not moving at all?

Bathrobes

Is actual use as much as we expected?

Pool towels

Is daily consumption exceeding our estimate?

After this data, par stock can be revised.

The first par stock plan is theory; real operations calibrate it.

What Is the Real Purpose of a Par Stock System?

The aim is not to buy as many textiles as possible.

The aim is also not to operate with as few textiles as possible.

The aim is:

The right textile, in the right quantity, in the right place, at the right time.

In a good system, housekeeping does not say:

“We've run out of clean towels.”

Purchasing does not say:

“Why did we buy so many towels?”

Finance does not say:

“Why is so much money sitting in the warehouse?”

And the guest never notices how complex a system is behind the textile operation.

Because they should not notice.

Conclusion

The answer to “How many sets of textiles should a hotel have?” is not as simple as:

“3 sets for every hotel.”

3 Par can be a strong starting reference.

But the real calculation:

Number of Rooms × Units of Product per Room × Target Par + Safety Stock

should be done by product.

Afterwards it should be tested against:

• laundry turnaround time,
• occupancy,
• attrition,
• supply lead time,
• storage capacity,
• room types,
• seasonal intensity.

Because in textile stock there are two wrong extremes.

Too little stock

It puts operations at risk.

Too much stock

It ties up capital unnecessarily.

The right point lies between the two.

And that is exactly the goal of good textile management:

Keeping operations running without the guest ever experiencing a textile shortage in their room, and without building up an unnecessary pile of textiles in the warehouse.

That is why Par Stock is not just a housekeeping term.

It affects the purchasing decision.

It affects the storage need.

It affects the laundry system.

It affects the opening budget.

It affects working capital.

And if miscalculated, it can even affect room sales.

In short:

Right Par Stock = Operational Security + Controlled Stock + Right Use of Capital
