Measuring Before Estimating Wall Covering Needs Measuring Before Estimating Wall Covering Needs
The most important step in estimating wallcovering is accurate measurements. Use a yardstick or steel tape measure, never a cloth tape measure. Take measurements in feet rounding off to the next highest half foot or foot. Draw a room diagram showing doors, windows and ceiling height. If a wall is unusually broken up with a fireplace, built-in bookcases, etc., a diagram with detailed measurements will be beneficial in figuring square footage of wallcovering needed.
Measure wall height from floor to ceiling. Exclude baseboards and moldings. Measure length of each wall including doors and windows. Find the total square feet of the wall(s) by multiplying ceiling height by total wall length. Subtract areas that will not be covered. (Standard doors are about 3 x 7 feet or 21 square feet; standard windows about 3 x 4 or 12 square feet.)
These calculations give the total number of square feet to be covered. Using this the number of rolls or linear yards of wallcovering can be determined.
In the right figure, each wall is 12' long with an 8' ceiling. Multiply 12 x 8 = 96 square feet for each wall, then multiply 96 x 4 (since there are four walls with 96 square feet each)= 384 total square feet for the room.
Metric Single Roll
|Repeat Length||Usable Yield|
|0" to 6"||25 sq. ft.|
|7" to 12"||22 sq. ft.|
|13" to 18"||20 sq. ft.|
|19" to 23"||18 sq. ft.|
These figures work well for normal sized walls. For unusually short (under 3 feet) or high (over 9 feet) they do not apply.
