Another Example of Why to Purchase Extra Wallpaper – Don’t Trust On-Line Calculators!

See that 3 1/2″ wide stripe of bare wall to the left of the strip of wallpaper? In order to cover this with wallpaper, I will need to take a full 9′ high strip of 27″ wide paper – that’s more than 20 square feet – and cut off just 4″ from the one side. The rest of that 9′ long strip of wallpaper will most likely go into the trash bin.

This is a good example of why you can’t calculate how many rolls you need to paper a room by figuring up square footage. You simply are not able to use every square foot of paper on that bolt!

On-line calculators don’t take into account the waste factor from matching the pattern, and the pattern repeat, nor trimming at floor and ceiling, or around objects (windows, doors, cabinets). Or situations like in the photo above, where most of the strip will go to waste.

Again – always best to have the wallpaper hanger measure first and calculate how much paper you need before you buy.
