How Many Rolls Do I Need?

Once you've measured your wall, working out the rolls is simple. Here's the plain-English method.

First, know your roll size

A standard wallpaper roll is 10 metres long and 53 centimetres wide. That's the size most of our rolls come in, but always check the product page — some designs differ, and our wall murals are sold as panels, not rolls (see How to Hang a Wall Mural).

The simple method (no pattern repeat)

Step 1 — How many drops fit across your wall? A "drop" is one full top-to-bottom strip of wallpaper. Take your wall width in cm and divide by 53 (the roll width). Round up.

Example: a 320cm wide wall ÷ 53 = 6.04 → you need 7 drops.

Step 2 — How many drops come from one roll? Take the roll length (1000cm) and divide by your wall height.

Example: wall is 260cm tall. 1000 ÷ 260 = 3.8 → 3 full drops per roll.

Step 3 — Divide and round up. 7 drops needed ÷ 3 drops per roll = 2.3 → you need 3 rolls.

If your wallpaper has a pattern repeat

A pattern repeat means each drop has to be cut a little longer so the design lines up with the drop beside it.

The quick rule: add the pattern repeat to your wall height before you do Step 2.

Example: wall is 260cm tall, pattern repeat is 53cm. Treat each drop as 313cm. Now 1000 ÷ 313 = 3.1 → still 3 drops per roll, but with a large repeat it can drop to 2. This is why we round up.

The golden rule: always buy a little extra

• Buy one spare roll on bigger jobs. Offcuts, mistakes, and future repairs all need paper from the same batch.
• Buy it all in one order so every roll comes from the same print run and the colour matches exactly.
