* Notes: This is an estimator which
enables you to approximate the amount (area) of wallpaper, number of rolls, and optional
trim, required for a given room, based on parameters entered. It calculates the square
footage of surfaces requiring wallpaper. We are ignoring the area occupied by doors
or windows because the requirements of trimming around windows and doors often requires as
much material as the area you are trimming around. Please remember that the calculation is
approximate.
If you wish to use
decorative trim, check the box. It calculates 1 trim strip; if you wish to use 2 or 3,
double or triple the quantity of calculated decorative trim rolls as a result. Decorative
trim is assumed to be at the ceiling and therefore is not hampered by doors or windows.
The requirement (and subsequent cost) in actual use will change if positioned in the
center of the wall or close to the floor because of doors and windows. Trim rolls are
about 15 linear feet long.
Enter the cost of
the wallpaper per roll (about 27 square feet) and the room dimensions. The total
price and the quantity of wallpaper required is calculated automatically. To do another,
click the Clear Values button and then enter a new set of values. You may also wish to
just change certain fields and recalculate. Please remember that due to cuts, patterns
that need to be matched at cuts, and non-usable ends, wallpaper rolls are generally
considered to be between only 85 and 95 percent usable. The smaller the pattern, the less
the waste. Trim border rolls follow the same guideline, but are generally considered to
have more waste since most people want an entire border without a cut on a wall.
Obviously, walls longer than 15 linear feet require a longer roll, if possible, or will
require a splice.
When you buy
wallpaper or wallcoverings, look for run numbers, lot numbers or run codings on the label
or roll. These numbers should be the same on each roll. Wallcoverings are printed in large
batches, and the colors can vary perhaps slightly, but nonetheless noticeably, between the
batches. To avoid the risk of running out, and to make sure you have extras in case you
need to patch an area, you may wish to buy an extra roll. To be sure you have enough
wallcovering to cover the room, our calculator rounds up and calculates on the average
USABLE quantity on a roll.
