FAQ
What is a standard wallpaper roll size?
Standard rolls are 530mm × 10m (width × length). Some brands use 700mm × 10m. Dimensions vary slightly by brand.
How much waste to allow?
Allow 10-15% for pattern matching and trimming. Large pattern repeats need more, solid colors need less.
Is wallpaper calculation different from paint?
Yes. Wallpaper is calculated by rolls considering width, length, and pattern matching. Paint is calculated by volume considering coverage area.
