How much wallpaper do I need?

Measure wall area in sq ft, then divide by the roll coverage (typically 25-30 sq ft per single roll). Add 15-20% extra for pattern matching and waste. Large patterns (>24 inch repeat) can waste 30% or more.

What is pattern repeat in wallpaper?

Pattern repeat is the vertical distance before the design repeats. A 24-inch repeat means every 24 inches the pattern starts over. You must align this at seams, creating waste. Larger repeats = more waste.

📐 Pattern Matching Guide

Straight Match: The pattern aligns horizontally across adjacent strips. Easier to hang, less waste (~15%).

Drop Match (Half Drop): The pattern drops by half the repeat on adjacent strips. Creates a brick-like layout. More waste (~20-25%).

Large Repeats = More Waste: A 36-inch repeat can waste 30% or more because you must trim full repeat lengths to match at the ceiling. Small repeats (<12") waste less.

Pro Tip: Order all rolls from the same batch/lot number. Dye lots can vary noticeably even in the same pattern.
