There are three key factors to determine how much wallpaper you will need.
Most wallpaper is priced and selected in single roll quantities but will ship in double roll bolts (hyper link to s/r d/r video). The size of the single roll may vary, but the most common is 20.5” wide x 16.5’ feet. A single roll of wallpaper that is 20.5” w x 16.5’ contains approximately 28 square feet of wallpaper. The amount of coverage will vary based on your pattern repeat.
The pattern repeat is how frequently the pattern appears in a strip of wallpaper. To create a seamless look, each strip of wallpaper needs to be lined up with the pattern repeat of the previous strip. The bigger the repeat the more waste and the need for more wallpaper.
Let’s put it back together!
Divide your total square feet by the number below based on your pattern repeat. random match (no repeat) divide by 28 pattern repeat is up to 18” divide by 23 pattern repeat is over 18” divide by 20 The final number will give you the number of single rolls recommended for your project. *Please note calculations are estimated based on a 20.5” wide roll with a pattern repeat over 18”.

Our philosophy on wallpaper purchases is it’s better to have extra than not enough. It is difficult at times to get the same run and dye lot numbers. Using a different run and dye lot could lead to some color variation. To make sure you have enough wallpaper we recommend
The majority of border is packaged and sold in 15-foot spools as a single unit. To determine how much border, your project requires:
Some border comes in a mural size and they are sold by the unit. Typically they are 12’ feet long.
Wall liner is a cost-effective alternative to repairing or replacing damaged walls. Wall Liner can be used for lining over plaster, cement block, paneling, and cracked walls. It provides a smooth base that you can then wallpaper over. However, depending on the condition of your walls, you may need to fill in deeper cracks or holes for best results. See our wall liner.
Wallpaper ships directly from the manufacturer to you and when ordering multiple patterns,
it may arrive in different packages at different times. When ordering multiple wallpaper patterns,
you should wait to schedule your wallpaper hanger, or wait to hang the wallpaper yourself, until
the entire order is received and inspected by you. Some contractors may charge a fee to cancel or
reschedule an appointment. Steve’s Blinds and Wallpaper does not cover installation fees for any reason.
