Centimetres or inches: same wall plan, one unit switch
Enter the wall in the units on your tape. This planner keeps the drawing and roll math in that system until you switch.

Answer: Pick centimetres or inches at the top of the cut plan, then enter wall width, height, and roll size in those units. Do not mix a metric wall with an imperial roll label without converting first.

Roll wrappers often print both systems. Tape measures usually do not. Mixing “400 cm wall” with “21 inch roll” inside your head is how strip counts go wrong before you cut.
On Wallpaper Cut Map the unit control changes the labels for the fields you type. The strip drawing and leftover length follow those numbers. Switch units only when you are ready to re-enter or convert every measurement.
After the plan looks right, open the cut list and print at 100% scale. The numbers are a cutting plan for one rectangular wall — not a promise that every roll in the shop is identical.
