Formula

Order width = Math.min(width_top,width_middle,width_bottom)-width_deduction; Order height = height-height_deduction; Width variation = Math.max(width_top,width_middle,width_bottom)-Math.min(width_top,width_middle,width_bottom)

How to use this tool

Enter the measured quantities and your own planning assumptions.
Review all calculated outputs and the stated limitations.

Try this example

{
  "width_top": 100,
  "width_middle": 99.7,
  "width_bottom": 99.8,
  "height": 150,
  "width_deduction": 0.5,
  "height_deduction": 0.5
}

Accuracy and scope

Use only deductions required by your supplier. Some suppliers already deduct clearance; avoid deducting twice.
