A car model rarely uses up a whole decal sheet, which makes it hard to judge how many sheets to buy. Enter the sheet dimensions, the size of a single decal and how many you are applying, and the tool returns how many come off one sheet and how many sheets the job needs. Add the soak and placing times and you also get the minutes the whole session will take.
Sheet width divided by decal width and rounded down gives the columns, the heights give the rows the same way, and the product is the count per sheet. Sheets needed is the decal count divided by that and rounded up. Leftover is the total sheet area minus the area the decals cover. No official soak time exists, so the figure comes from your own measurement. Current as of October 2026.
The math assumes every decal is the same size and cut on a grid. Real sheets mix sizes and pack tighter than that. Setting solution technique, clear coat drying time and decal shelf life are not covered. Treat the figures as a reference and keep one spare sheet on hand.
Frequently Asked Questions
The math assumes you cut the decals out on a straight grid, so when the sheet dimensions do not divide evenly by the decal dimensions the leftover grows on its own. A real sheet mixes decals of several sizes and packs them tighter.
Backing paper releases at a different pace on every product and no official figure is published. Dunk one decal as a test, time how long until it starts sliding off the backing, and use that.
No. Only soak time and placing time are multiplied by the decal count. Brushing on setting solution and waiting for it, and clear coat drying, have to be added separately.
