Wallpaper installation cost can vary greatly depending on the wallpaper material, the intricacy of the design, and the size of the project. However, a general estimate would be about $2 to $5 per square foot for a professional installation. So for example, if you were to install wallpaper in a room that is 10 feet wide by 12 feet long, it would cost between $200 and $600. Keep in mind that these are just general estimates and your actual cost may be different. Always consult with a professional wallpaper installer to get an accurate quote for your specific project.

Wallpaper installation generally costs anywhere from $100 to $400, depending on the size of the room, the type of wallpaper, and the complexity of the installation. If you're doing it yourself, you can expect to spend around $50 in materials.
