How many rolls of wallpaper do I need?

Measure the walls, take off the doors and windows, and divide by what one roll covers: about 56 square feet for a US double roll, about 54 for a Euro roll. Then add one roll for mistakes and repairs.

Rule card for Wallpaper: US double roll: about 56 sq ft; Euro roll: about 54 sq ft; One batch number, one spare roll.
US double roll: about 56 sq ft.

Work out your wallpaper

We use the low end of each roll's coverage and add one spare roll for mistakes and repairs. A large pattern repeat loses more paper: add a roll or two for a big repeat.

Single, double and Euro rolls

In the US, wallpaper is often priced by the single roll but sold in double rolls; a double roll covers about 56 square feet or a little more, and makers list 56 to 70, so read the label of the paper you choose. A standard Euro roll is 0.53 by 10.05 meters, about 5 to 5.3 square meters: 54 to 57 square feet, close to a US double roll.

Batches and repeats

Buy every roll with the same batch number, and order the whole job at once: the color can shift slightly from one batch to the next, and a later order may come from another. A big pattern repeat loses more paper matching the strips, so it needs more rolls. Cut each strip about 2 inches long at the top and bottom, then trim it on the wall.
