Wallpaper is better than paint when you want to add intricate patterns, texture, or unique personality that paint alone can't replicate. Wallpapers like linen weaves or grasscloth offer tactile depth and a distinctive look perfect for accent walls or feature areas. They work especially well in low-traffic rooms where durability is less of a concern and where you want permanent visual interest. However, wallpaper requires more installation effort and higher maintenance compared to paint.
