O Cálculo

Rolo padrão: 10,05 × 0,53 m = 5,3 m². Área ÷ 5,3 = rolos. Com estampa: +15-20%. Quarto 4×3,5 a 2,50 m: ~7 rolos sem estampa, 8-9 com. Compre do mesmo lote.

No Brasil

Papel adesivo (removível) é a tendência — perfeito para aluguel. R$50-150/rolo. Não danifica a parede. Aplica-se sem massa. Popular em quartos infantis que mudam de tema a cada 2-3 anos.

⚡ 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.
