Wallpaper Calculator: Measure Your Walls Accurately

This tool helps you quickly calculate how much wallpaper you need for your room.

How to Use the Wallpaper Calculator

This wallpaper calculator helps you determine the number of wallpaper rolls you need to cover a wall. Simply enter the dimensions of your wall and the dimensions of a wallpaper roll, then click “Calculate”.

Calculation Breakdown

  • Wall Area = Wall Width x Wall Height
  • Roll Area = Roll Width x Roll Length
  • Rolls Needed = Ceiling(Wall Area / Roll Area)

Limitations

This calculator assumes that you have no windows or doors in your wall, and that you will not be matching patterns on the wallpaper. Always buy one extra roll to account for any mistakes or pattern matching.
