Wallpaper Roll & Cut List Calculator
Calculate how many wallpaper rolls you need based on wall dimensions, roll size, and pattern repeat type.
Buy the right number of wallpaper rolls—even with pattern repeats
Perfect for DIYers and installers who want a fast, practical roll count before ordering.
How the roll count is calculated (strips, cut length, and waste)
Finally, it divides the total required strips by usable strips per roll and rounds up to get the total rolls to buy, with coverage/waste estimates to show what you’ll likely lose to matching and trimming.
Pattern repeat choices change usable strips per roll
If the repeat behavior you’re using in real installation differs from the option selected (or if the manufacturer provides a specific repeat length in inches/cm), results can vary—use the closest repeat setting and verify against the product’s instructions.
When the calculator can’t produce even one usable strip
Another common edge case is when wall width doesn’t “fit” neatly into strips—rounding up the number of strips handles the extra edge waste you’ll typically trim.
Important assumptions (doors/windows, borders, and layout)
If your wall has many cut-outs or you’re matching a border/feature requiring additional alignment beyond standard repeats, plan for extra material beyond the calculator’s estimate.
