Most wallpaper measuring guides recommend calculating the square footage of your walls and then multiplying this figure by the width of your chosen wallpaper. This will give you the number of usable floor-to-ceiling strips that your wallpaper roll will have.

A quality metal measuring tape is essential for accurate wall measurements. A ruler can also be helpful for making straight and even lines when recording measurements.

Next, determine the adjusted height of each wall by adding the wallpaper’s pattern repeat (provided in the product specification) to the height measurement. Finally, divide the length of a wallpaper roll by the adjusted height of each wall to find out how many wallpaper strips you need to cover your room’s walls.


A tape measure is essential to measuring walls accurately. A calculator and a notepad or paper for recording measurements, calculations and additional notes are helpful tools as well.

Take a vertical measurement of each wall from the floor to the ceiling, excluding baseboards and crown molding unless you plan on wallpapering those as well. Note the height of each wall in inches or centimeters, and write it down for later reference.

Then add the widths together and enter them into Graham & Brown roll calculator, which can be found on the product page for each wallpaper pattern. Finally, add up the height of each wall and divide by the height of the wallpaper pattern repeat to get an adjusted height that will allow you to cut floor-to-ceiling strips from one wallpaper roll. This will account for potential waste as you line up the pattern and trim off excess.
