Oulu 27 – Onyx | Blacks Geometrics Wallpaper for Office, Accent Wall, and Dining Room

Each roll is 27 in | 68.5 cm wide and 9 yd | 8.2 m long. Each strip covers about 27 inches of wall width, so divide the width of your wall by that to work out how many drops you will hang.

60.8 ft² | 5.6 m², based on the manufacturer's stated dimensions. That figure is before pattern matching and trimming, so plan on getting a little less than the full number in practice — allow extra for the repeat and for cuts around doors and windows.

It is sold by the double roll — one purchase is a continuous double-roll bolt. When you estimate quantity, work out how many single rolls you need first, then order half that many double rolls, rounding up.

It is a half drop match with a repeat of 20.8 in | 53 cm. Allow a little extra material so the pattern lines up correctly between strips — the longer the repeat, the more you should allow.

Measure the width and height of each wall, add the areas together, and divide by the coverage of one roll (60.8 ft² | 5.6 m²) — then add roughly 10–15% for the pattern repeat and trimming. Our wallpaper roll calculator will do the arithmetic for you, or send your measurements to sales@houstonwallpapering.com and we will confirm the quantity before you order.
