Linen Par Levels for Hotel Housekeeping: A Working Formula

A linen par level is the number of complete linen sets a hotel keeps in circulation per room to cover what is on the bed, what is in the laundry, and what is in storage as a buffer. The working formula is: par level equals the number of sets needed in one full rotation, one on the bed, one in the wash, one in storage, adjusted up if laundry turnaround runs longer than a single day.

Most hotels run somewhere between 3 and 5 par for standard bed linen, depending almost entirely on whether laundry is in-house or outsourced, and how fast that turnaround actually is, not on room count or star rating.

Par level (sets per room) = 1 (on the bed) + 1 (in the wash) + safety stock, where safety stock covers the laundry cycle time and any buffer for stained or damaged items pulled from rotation.

• 3 par: same-day, in-house laundry with fast turnaround. One set on the bed, one in the wash cycle, one clean set in storage ready to swap.
• 4 par: standard for most independent hotels with in-house laundry running a normal daily cycle, or a same-city outsourced laundry with next-day return.
• 5 par: outsourced laundry with a two to three day turnaround, or any property that wants a genuine buffer against a laundry service disruption without an emergency reorder.

A 60-room hotel running 4 par on standard queen sheet sets needs 240 complete sets in circulation. At roughly 3 pieces per set (fitted sheet, flat sheet, one duvet cover, adjusted for your actual bedding configuration), that is 720 individual pieces to keep the property running without a stockout, before accounting for towels and bath linen, which typically run their own, usually higher, par level given faster daily turnover than bed linen.

Run the same property at 5 towels per room (bath, hand, face, bath mat and a spare) against a 5 par towel policy, and that adds a further 1,500 individual pieces. The full linen inventory for a mid-sized property routinely runs into several thousand individual pieces once bed linen, towels and any F&B napery are counted together, which is exactly why an accurate par level, not a rounded-up guess, has a real effect on both storage space and working capital tied up in stock.

• Laundry turnaround time is the single biggest factor. A slower cycle needs a higher par to avoid a stockout, full stop.
• Occupancy pattern matters more than room count. A resort with heavy weekend turnover needs more buffer stock than a steady midweek business hotel with the same number of rooms.
• Storage space is a real constraint, not just a formula input. A property without the back-of-house storage to hold a higher par level needs to solve that first, or accept a tighter laundry cycle as the alternative.
• Seasonal properties need a higher par during peak season and can run leaner in the off-season, rather than holding one fixed par level year-round.
• Housekeeping equipment and trolley capacity plays a role too. Par levels that look right on paper can still create a daily bottleneck if housekeeping trolleys cannot physically carry enough clean linen for a full floor round.

Towel weight changes both laundry cost and par level. See hotel towels: GSM, cotton type and how long they last.
