Plan a wallpapering job without overbuying by estimating rolls from your actual wall dimensions. Enter the total length of wall to cover and the wall height in feet, then the width and length of one roll, which for many standard rolls is about twenty one inches wide by thirty three feet long. The calculator figures how many full drops one roll yields at your ceiling height, then how many drops the room needs across its perimeter, and finally the roll count rounded up. It also adds a modest waste allowance so you have enough to match patterns at seams and trim around outlets. Doors and large windows can be subtracted by lowering the wall length you enter. Everything computes instantly in your browser so you can test different roll sizes and room shapes freely.
It finds the wall area from length and height, then divides by the usable coverage of one roll to find how many rolls you need.
Roll coverage already assumes some trimming waste. Add an extra roll if your paper has a large pattern repeat that increases waste.
Yes. Wallpaper is sold in whole rolls, so always round up to the next full roll to avoid running short.
