Frequently Asked Questions
How does pattern repeat affect how much I need?
Pattern repeat means the wallpaper design repeats at regular intervals. When hanging, you need to align the pattern between strips, which means cutting away usable paper. A large pattern repeat (12+ inches) can waste 15-25% more wallpaper compared to a solid or no-repeat design. Always check the pattern repeat listed on the roll before ordering.
