Wallpaper calculation FAQs
How to correctly calculate wallpaper rolls?
Enter accurate wall dimensions, specify roll size and pattern repeat (if any), add windows and doors. The calculator will automatically account for all factors and give you an accurate result.
What is pattern repeat and why is it important?
Pattern repeat is the vertical distance between matching pattern elements. It's important for patterned wallpaper as it affects how many strips you can get from one roll and requires more material for pattern matching.
Should I buy extra wallpaper rolls?
Yes, always buy at least 1 extra roll for unexpected situations, pattern matching, repairs, and to ensure you have enough material from the same batch (to avoid color differences).
