Almost every linen shortage traces back to the same thing: par levels set once, on a good guess, and never revisited. A par level is simply how many sets of each item you keep in circulation so that clean linen is always available while the rest is in use, in transit or in the wash. Set it too low and you run short on the busy days. Set it too high and you've got capital sitting in a closet.
Start with three par sets, not one
The old rule of thumb is three pars: one on the bed (or shelf), one in the laundry cycle, and one on the shelf ready to go. That's the floor, not the answer. The right number flexes with how fast your rooms turn and how reliable your delivery rhythm is.
- One par in use — dressed on beds and stocked on housekeeping carts.
- One par in process — soiled, in transit, or being laundered.
- One par in reserve — clean and on the shelf for the next turnover.
Then size to your real demand, not your room count
A 120-room hotel running 95% occupancy with a Saturday checkout wave needs more buffer than a 120-room hotel at 60% midweek occupancy. Look at your actual numbers: average occupancy, your single busiest turnover day in a normal week, and the gap between linen pickups. The buffer exists to cover that busiest day plus a delivery cycle — not the average.
Par levels should follow your real demand, not a spreadsheet guess. Review them after a few weeks and adjust.
Build in the peaks you already know about
Most shortages aren't surprises — they're a conference, a wedding block, a holiday weekend you booked months ago. Stage extra ahead of known peaks rather than reacting after the carts run dry. A good linen partner forecasts around your calendar and pre-positions inventory so a sold-out weekend doesn't become a 2 p.m. scramble.
Revisit quarterly
Occupancy patterns drift, you add a room type, a new event lands on the calendar. Par levels that were right in January can be wrong by June. Treat them as a living number you check each quarter — and lean on your account manager to flex the route when demand moves between reviews.
Get the pars right and 'we ran short' quietly disappears from your housekeeping stand-up. That's the whole goal: linen you never have to think about.
