What is a pattern repeat?

Pattern repeat is the vertical distance before the design repeats. A large repeat (24-36 inches) wastes more material because each strip must be aligned to match adjacent strips, requiring longer cuts.

How wide are standard wallpaper rolls?

US rolls are typically 27 inches wide × 27 feet long = 57 sq ft. European double rolls are commonly 20.5 inches wide × 33 feet long = ~56 sq ft usable.
