What this workbench does
Plan a regular grid of identical decals across a vinyl roll, including gaps and leader waste.
It combines an editable calculator, baseline comparison, one-input sensitivity chart, transparent formulas, worked examples and a printable measurement sheet.
How to assess the result
Check that at least one decal fits across, then add the cutter’s feed allowance before ordering a roll.
The calculations implement the stated geometric or arithmetic model. They are estimates where real materials, equipment or processes differ from that model. The specific assumptions are listed on the calculator and reference pages.
