FormulaLiners in first orientation = Math.floor(rollWidth/(trayW+2*overhang))*Math.floor(rollLength/(trayL+2*overhang)); Liners in rotated orientation = Math.floor(rollWidth/(trayL+2*overhang))*Math.floor(rollLength/(trayW+2*overhang))

Made for real tasks

Worked example

Inputs

Paper roll width
38 cm
Paper roll length
1000 cm
Tray base width
25 cm
Tray base length
30 cm
Overhang on each edge
2 cm

Expected results

Liners in first orientation
29 liners
Liners in rotated orientation

How to use this tool

  1. Enter paper roll width, paper roll length, tray base width, tray base length, and overhang on each edge in the displayed units.
  2. Calculate and use each labeled result for baking paper tray liner yield. Compare the result with a measured sample before committing materials.

Try this example

{
  "rollWidth": 38,
  "rollLength": 1000,
  "trayW": 25,
  "trayL": 30,
  "overhang": 2
}

Accuracy and scope

Uniform rectangles without mixed-orientation nesting; paper temperature and appliance compatibility must be checked separately.
