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