| There are several ways to calculate how much wallpaper
you will need and many variables can come into play,
such as vaulted ceilings, paper width, pattern repeat,
number and size of doors and windows. Just as two
situations are not exactly alike, no single method
of calculation will work perfectly every time. It
is always a good idea to do your measurements a couple
of ways and then compare them. As the carpenter says,
"measure twice, cut once." It is also a
good idea to order a little more than you need in
case you make a mistake or need to make a repair sometime
later.
When you search for wallpaper on our Website, we provide
a built-in calculator to help you determine how much
you need to order based on your room dimensions and
the specific size and pattern repeat of the design
you select.
If you want to develop a quick estimate of your needs,
use the estimating charts or the square footage method
described below.
Remember that wallpaper is priced by the single roll,
but is sold in double- or triple-roll bolts. This
method of packaging creates longer continuous runs
of paper and usually results in less waste. So make
sure your measurements adjust for the bolt packaging
of your particular paper.
Always round up to the nearest foot when taking your
measurements and use a yardstick or steel tape measure,
not cloth.

After you have determined the number of rolls you need
from the charts above, you can deduct one half roll
for each standard size door or window. However, many
people find that the little they may save by doing
so does not compensate for the peace of mind that
comes from having extra paper in case they run short,
make mistakes, or need to make a repair. Do not deduct
for windows and doors if measuring for borders or
ceilings.
Square Footage Method
- Multiply the length of each wall by its width to get
the square footage
- Add the square footage of all walls together
- Find the pattern repeat for the wallpaper you have
chosen from the website, the sample book, or the
product label
- Divide the total square footage of your project by
the usable yield figure shown in the table below:
| |
And the roll width is 20.5"... |
And the roll width is 27"... |
| If
the pattern repeat is... |
Divide square footage by... |

- This is the number of single rolls you need. Divide
by 2 and round to the nearest even number to get
the number of double-roll bolts needed. Divide by
3 if the product is packaged in triple-roll bolts.
While product is priced by the single roll, it is
packaged and ordered in full bolts.
