Managing linen inventory is critical for smooth hotel operations, cost control, and guest satisfaction. Prostay’s Hotel Linen PAR Calculator helps you determine exactly how many linens your property needs — balancing operational efficiency, laundry turnaround times, and seasonal demand. Avoid overstocking, prevent shortages, and keep your housekeeping team fully equipped.

What Is a Linen PAR Level?

In hospitality, PAR (Periodic Automatic Replacement) level refers to the standard number of linen sets needed to service all rooms while accounting for linens in use, in laundry, and in storage.
A common rule of thumb is 3–5 PAR:

  • 1 PAR in rooms
  • 1 PAR in laundry
  • 1–3 PAR in storage or rotation

However, the ideal number varies by property size, occupancy rate, change policies, laundry turnaround, loss rates, and seasonal fluctuations. This calculator uses data-driven formulas to give you a precise, customized recommendation.

How do I calculate the correct linen PAR level?
A basic formula is: PAR Level = (Daily Linen Requirement × Laundry Turnaround Days) + Safety Stock Prostay’s calculator refines this by also factoring in occupancy rate, change frequency, loss rates, and seasonality.
What is the industry standard for hotel linen PAR levels?
Most hotels operate with 3–5 PAR, but the exact level should be based on your occupancy, laundry turnaround, and operational policies.
How often should I review my hotel linen PAR levels?
At least twice a year, or whenever there’s a change in occupancy patterns, laundry processes, or service standards.
Can I use this calculator for other textiles like uniforms or spa linens?
Yes — simply add them as custom items with the correct “pieces per room” or per service point.
What does PAR stand for in hotel linen management?
