Calculating Wallpaper Rolls
Pattern Repeat and Waste

Berechnung

Rolle: 10,05 × 0,53 m = 5,3 m². Wandflaeche / 5,3 = Rollen. Mit Rapport: +15-20%. 4×3,5 m bei 2,60 m: ~7 Rollen ohne Muster, 8-9 mit. Gleiche Charge kaufen!

Vlies vs. Raufaser

Vliestapete: Kleister auf die Wand (einfacher!). Raufaser: wird ueberstrichen, deutscher Klassiker. Vlies hat Raufaser als meistverkaufte Tapete abgeloest.

⚡ CalcWolf Insight

The #1 wallpaper mistake: not ordering from the same dye lot. Colors vary slightly between production runs. If you run out and reorder, the new rolls may not match. Always order your full quantity plus 1-2 extra rolls in a single purchase. Return unused, unopened rolls if the store allows it.
