Mary Insana on Nov 05, 2012You can Google How to estimate for wallpaper but here is some information Measure the height of each wall with a tape measure For an example, let us say you have 8foothigh walls. Measure the length of each wall with the tape measure. For our example, let's say the room is square and each wall measures 20 feet in length. Since you have four walls, this means you have 80 feet of wall length. Multiply the length and the width together. For our example, this is 8 feet multiplied by 80 feet. The total square footage for your wall space is 640 square feet. Divide your total square footage by the amount of square footage supplied with each roll. A standard roll of wallpaper measures 36 square feet. Subtract 17 percent for waste and you usually get approximately 30 square feet of usable material on each roll. For our example, divide 640 square feet by 30 square feet. Thus, you'll need 21.33 rolls of paper  round it up to 22 rolls.Helpful Reply

WallsTreat Studio/ Kass Wilson on Nov 06, 2012Be sure to adjust for the size of the pattern repeats. The wallpaper books will tell you how.Helpful Reply


3po3 on Nov 06, 2012That was 15 single rolls, according to Lowe's. But again, they suggest using it as an estimate, and it sounds like Kass has some great advice for you, too.Helpful Reply


Carol C on Nov 07, 2012Thanks, Steve, I think you are correct. Will start with 8 doubles and go from there. Thanks everybody for your input. Love this site!Helpful Reply


WallsTreat Studio/ Kass Wilson on Nov 08, 2012Be sure to order plenty. Wallpaper is printed in dye lots. If you need to go back and get more, you may not be able to find it in the same dye lot and there may be a slight shift in color. Ask them what their return policy is. Most of them will allow you to return any unopened packages. So, by extra and return what you don't need.Helpful Reply


Tim McLaughlin on Mar 25, 2013The numbers needed for determining rollage are the pattern repeat, length and width of the rolls and ceiling hight .Unless a textile or grass cloth is being installed the width is generally 20" or 27" wide.With average hight ceilings you will get 3 strips out of a double roll that is 27" wide . papers that are 30" wide will provide 3 or 4 strips a double depending the pattern repeat. 3 strips of 27"wide paper will = 81" .divide your total perimeter x 81" and that will be your total amt. of double rolls. Do the same thing with 30" paper. You will get at least 3 strips per double roll.3x20" = 60". divide 60 into your total perimeter and that again will be your total amt. of double rolls.example;10x 10 foot room = 40' perimeter x12 = 480".....480" div x 60 = 8 double rolls.Helpful Reply
