Wallpaper Calculator — How Much Do I Need?
Tell us your wall sizes and we’ll estimate how many rolls you need. Our calculator uses the proper “drop” method — it allows for pattern matching and trimming, not just bare area — so you order the right amount.
Roll details (adjust to match your chosen wallpaper)
Defaults are for a standard roll (10m × 53cm). The exact roll size and pattern repeat are listed on each product page — pop them in here for the most accurate result.
Tip: always round up and order a little extra — keep an offcut for future repairs, and buy all your rolls at once so they’re from the same batch. This is an estimate; the bigger the pattern repeat, the more you’ll need. If you’d like us to check your quantities, just get in touch.
