Living Room Wallpaper Calculator

Living rooms tend to be the largest room you’ll wallpaper, often with more doors and windows — here’s what to expect when you plan one.

Get my living room roll count

The planner handles custom roll sizes and pattern repeat too — open it for a living room sized roughly 5m × 4m.

Quick roll estimate

Enter your total wall length and height for an instant estimate — standard 53cm × 10m roll, adjustable below.

Chimney breasts and alcoves

Treat a chimney breast as extra wall length, and alcoves either side as their own short strips — measure each separately for the most accurate total.

Open-plan spaces

If your living room opens into a hallway or kitchen, decide where the wallpaper will logically end and only measure that section.

Larger rooms benefit from a buffer roll

On bigger jobs, order slightly more than the exact estimate to cover pattern-matching waste across many more strips than a small room needs.

Common questions

Should I paper all four walls or just one?

Many living rooms use wallpaper on a single feature wall with paint elsewhere. Measure just that wall for a feature-wall plan.

How do bay windows affect the count?

A bay window interrupts more wall than a standard window — measure its full opening width, not just the flat frontage.

Ready to plan the full project?

Save your measurements, plan every room in the house, and get the exact cutting plan — seams placed, waste shown — before you buy a single roll.
