Open-Plan Living Room Wallpaper: Choosing a Wall and Getting the Count Right
An open-plan kitchen and living room is usually too large to wallpaper entirely, and the mix of zones — cooking, dining, sitting — means different walls have different practical requirements. The most common approach is a single feature wall in the living zone, which gives the space a focal point without committing to paper near a hob or dishwasher. Here's how to choose that wall and order for it accurately.

In an open-plan space, the choice of wall determines everything that follows — which paper is suitable, how many strips are needed, and where the seams land. A wall behind a sofa, a dining area, or a fireplace is typically the best candidate: it's the one that gets looked at most, and it's usually the furthest from kitchen humidity.
Kitchen walls need moisture-resistant paper
A wall adjacent to or shared with a kitchen — particularly one near a hob, sink, or kettle station — is exposed to significantly more moisture and grease than the living side of the room. Standard wallpaper is not suitable there. If the wall you want to paper is within a few metres of the cooking zone, check the paper's specification for washability or moisture resistance before ordering.
High ceilings mean fewer strips per roll — and more rolls overall
Open-plan rooms often have higher ceilings than standard-height rooms. A ceiling 2.8m or 3m high means each strip needs to be longer, which reduces how many strips you get from a single roll. A roll that yields three standard strips may yield only two in a high-ceilinged space — that changes the roll count significantly on a wide feature wall.
Measure the feature wall's actual width, not the room's perimeter
An open-plan room's perimeter is large, but a feature wall in the living zone is often one bounded section of one wall. Measure its width from corner to corner (or from wherever the paper will stop), and use that width to work out the strip count — not the total room dimensions.
Large patterns look proportional in large spaces — but cost more per roll
An open-plan room gives a large-scale pattern the space to read well, and a bolder design often suits the proportions better than a small repeat. The trade-off is that a larger pattern repeat wastes more length per strip, and in a tall room with longer strips, that waste compounds. Calculate the roll count with the actual repeat distance, not a rough estimate.

Should I paper all four walls of an open-plan room?
Rarely — a large open-plan space with wallpaper on every surface can feel visually busy and is expensive to paper. A single feature wall in the living zone is the standard approach, giving the room a focal point without the cost or complexity of covering every wall.
Can I use standard wallpaper near a kitchen in an open-plan room?
It depends on proximity to the cooking zone. A wall directly behind a hob or sink needs something moisture-resistant. A wall five metres away in the dining area is usually fine with standard paper. Check the manufacturer's specification if you're in any doubt.
Does a fireplace wall count as a feature wall even if it's not perfectly flat?
Yes — a chimney breast with its alcoves either side is one of the most common feature wall treatments. The wall splits into three sections (the breast face and the two alcove returns), each of which needs its own strip count. Plan them as separate panels rather than one flat wall.
