To know how many wallpaper rolls do I need for a 12×14 wall,
Measure the Wall Size: Measure the height and width of the wall where you want to install wallpaper. In this case, the wall size is 12 ft × 14 ft.
Calculate the Total Wall Area: Multiply the height by the width to find the total square footage. 12 ft × 14 ft = 168 sq ft total wall area.
Deduct Doors or Windows: If the wall has windows, doors, or large openings, subtract their area from the total. For example, if a window is 12 sq ft, the usable wall area becomes 156 sq ft.
Check Wallpaper Roll Coverage: Wallpaper rolls usually have a fixed coverage area:
Single roll: Covers about 27 sq ft, Double roll: Covers about 54 sq ft (most common option), Triple roll: Covers about 81 sq ft (used for larger spaces or murals).
Calculate the Number of Rolls: Divide the total wall area by the coverage of one wallpaper roll. For example, if your wall area is 168 sq ft and one double roll covers 54 sq ft, then 168 ÷ 54 = 3.1. This means you will need 4 rolls of wallpaper to cover the wall completely.
Round Up the Quantity: Always round up to the next whole roll to avoid shortage.
Add Extra for Wastage: Add 10 to 15% extra wallpaper for pattern matching, trimming, and mistakes.
Final estimate for a 12×14 wall, you will need: 4 double rolls of wallpaper (recommended) Or 7 single rolls if sold individually.
If your wallpaper has large patterns or designs, you may need one extra roll to ensure proper alignment.
