Le Calcul

Rouleau standard : 10,05 × 0,53 m = 5,3 m². Surface des murs - portes/fenêtres ÷ 5,3 = rouleaux. Avec motif à raccord : ajoutez 15-20%. Pièce 4×3,5 à 2,50 m : ~7 rouleaux sans motif, 8-9 avec. Achetez du même lot — les teintes varient.

Application

Intissé : collez le mur. Traditionnel : collez le papier et laissez détremper. Le premier lé au niveau laser est crucial — tout le reste suit.

⚡ 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.
