The formula to calculate the required yardage for wallpaper is:
\[ Y = \frac{W \times H \times R}{36} \]
Where:
Wallpaper yardage refers to the measurement of wallpaper length in yards. It is crucial when purchasing wallpaper for a room or project, as it determines how much wallpaper is needed to cover a specific area. The yardage is typically listed on the wallpaper packaging or in the product description. To calculate the required wallpaper yardage, measure the height and width of the walls, then multiply these figures to get the total square footage. This figure is then divided by the square footage that a single roll of wallpaper can cover to determine the number of rolls needed. Additional yardage may be required to match patterns or account for windows and doors.
Example 1:
Using the formula:
\[ Y = \frac{120 \times 96 \times 24}{36} = 7680 \text{ yards} \]
Example 2:
Using the formula:
\[ Y = \frac{150 \times 108 \times 18}{36} = 8100 \text{ yards} \]
