How Much Wallpaper Do I Need?
To calculate the amount of vintage wallpaper that you need, first measure the height of your wall from baseboard to ceiling. Then measure the length of each wall from corner to corner. Multiply the length (in feet) by the height to arrive at the square footage of the wall. ( L x H = Sq. Ft.)
Subtract the area of large openings such as archways and doors but go ahead leave the area of windows and smaller obstructions in your calculations. The wallpaper that would cover up these areas will be helpful when going around the doorways and in other odd places.
Repeat this process for each wall and add up your results to arrive at the total square footage of your space.
Divide your total square feet by 50 square feet and you will have the number of double rolls that you need. (One double roll will cover at least 50 square feet of wall space. If your wallpaper pattern has a short repeat length, you might be able to cover 55 sq feet.)
An extra roll is always good. It’s better to have a little too much than not enough. Any extra wallpaper will come in handy for human errors in the process of hanging or for repairs down the road. A good rule of thumb is purchasing 1 extra roll for every 6. If the pattern is a very large design or an extra long repeat, you might consider 1 extra roll for every 4.
If you need a lot of wallpaper for your space, be sure to visit our "8 or more double rolls" section under the "Browse Catalog" tab.
