📜 Wallpaper Calculator

Hanging wallpaper can transform a room, but one of the biggest challenges is knowing how many rolls to buy. Buy too few, and you'll be searching for the same batch — which may not be available. Buy too many, and you've wasted money on rolls you can't return. Our Wallpaper Calculator takes the guesswork out of your decorating project.

Our calculator factors in pattern matching — the larger the pattern repeat, the more wallpaper you'll need due to off-cuts. We also account for windows and doors, so you don't over-order. Simply enter your room dimensions, choose your roll size, and select your pattern repeat, and we'll tell you exactly how many rolls to buy.

What our wallpaper calculator does:

💡 Pro Tip: Always buy one extra roll for future repairs. Wallpaper patterns can be discontinued, and having a spare roll means you can replace damaged sections without trying to match an old pattern.
