How to Use This Calculator
  1. Enter the daily number of flatwork pieces (sheets, pillowcases, tablecloths) to iron.
  2. Set the average piece area in square feet and the ironer's feed speed in feet per minute.
  3. Input operating hours per day to calculate required throughput.
  4. Review the required square feet per hour and the number of lanes/rolls needed.
  5. Check the recommended roll width and heating (BTU) capacity, plus pieces-per-hour throughput, to size the machine.

What each input means

Daily flatwork pieces
Daily sheets, pillowcases, tablecloths to iron.
Avg piece area (sq ft)
Average square footage of a flatwork piece.
Operating hours/day
Hours of ironer operation per day.
Ironer speed (ft/min)
Feed speed of the ironer in feet per minute.

What each result means

Required sq ft/hr
Square feet per hour throughput needed.
Lanes/rolls needed
Number of ironer lanes or machines needed.
Roll width (in)
Recommended ironer roll width.
Heating (BTU)
Total heating capacity needed.
Pieces per hour
Required pieces per hour throughput.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Daily flatwork pieces = 500, Avg piece area (sq ft) = 25, Operating hours/day = 8, Ironer speed (ft/min) = 50 = 4 input(s) provided
  2. Calculate Required sq ft/hr
    Required sq ft/hr = totalSqFtDay / hoursPerDay
    1563 = 1563
  3. Calculate Lanes/rolls needed
    Lanes/rolls needed = ceil(reqSpeedFtPerMin / speedFtPerMin)
    1 = 1
  4. Calculate Roll width
    80 = 80
