Measure the height and width of each wall before ordering. Pasadena comes on wide 36 in rolls with a 25 in (63.5 cm) vertical repeat and a straight match. On an 8-foot wall, each strip uses four full repeats (100 in), so expect about two full-height strips from each 8-yard double roll.
Budget roughly 15–20% extra for matching, trimming and installation waste, and have your installer confirm the roll count from your measurements. See our guide: How much wallpaper do I need?
