Kitchen Wallpaper Calculator: How Many Rolls Once You Exclude Cabinets and Splashbacks?

A kitchen is deceptive to estimate because the floor area suggests a mid-size roll count, but most of the wall is hidden behind units, appliances, and tiled splashback zones by the time you actually look at what needs papering. The real calculation starts with figuring out how much wall is genuinely exposed, not the room's total perimeter — and it needs a washable paper to survive the environment once it's up.

Measure only the exposed wall, not the whole perimeter

Walk the kitchen and note where fitted units, the fridge, and any built-in appliances sit against a wall — that wall space effectively doesn't exist for wallpaper purposes. What's left is usually a strip above the counter and units, a section around a doorway or window, and any wall not taken up by cabinetry at all. Measure only these genuinely visible sections rather than the room's total wall width.

Splashback zones stay tiled, not papered

The wall directly behind the hob and the sink is almost always tile, glass, or a metal splashback rather than wallpaper — a fixed exclusion regardless of the rest of the room's plan. Note the width of each splashback zone and leave it out of your measurements entirely; including it in the calculation just inflates a roll count for paper you're never going to hang there.

Choose a washable, wet-area-rated paper before you calculate

Grease from cooking and steam from the hob and dishwasher put a kitchen wall under more strain than almost any other room except a bathroom. Standard paste-the-paper wallpaper stains and lifts here within months. Choose a vinyl-coated or specifically wet-area-rated wallpaper before you measure, since these sometimes come in a slightly different usable width than a standard decorative paper, which changes the drop count.

Calculate drops for each exposed section separately

Once you've identified the genuinely paperable sections — above the units, around a window, on a wall with no cabinetry — divide each one's width by the usable strip width, round up to a whole number of drops, and multiply by the cut length (wall height plus pattern repeat). Sum the sections together rather than treating the kitchen as a single continuous wall run, since the gaps from cabinetry break up what would otherwise be one strip into several shorter, separately-cut ones.

Add a slightly larger buffer than a plain room

A kitchen's many small, interrupted sections generate more offcut waste per roll than a room with long uninterrupted walls, the same effect a bathroom sees. Add at least one buffer roll beyond the calculated total, and two if the paper has a repeat above 30 cm, since the short off-cuts from around units and appliances are rarely long enough to reuse elsewhere.

Common questions

How many rolls of wallpaper do I need for a kitchen?

A typical kitchen of around 4x3m with most walls partly covered by units and appliances usually needs 4-7 rolls of a washable, wet-area-rated paper for the genuinely exposed sections — considerably fewer than the floor area alone would suggest, since cabinetry removes a large share of the wall.

Do I need to paper behind the fridge or cooker?

No — skip any wall section that will be permanently hidden behind a fitted appliance or unit, the same principle as skipping the wall behind a wardrobe in a bedroom. Measure only what will actually be visible.

Is any wallpaper suitable for a kitchen?

No. Standard paste-the-paper wallpaper stains and can lift with grease and steam exposure. Choose a vinyl-coated or wet-area-rated paper designed for kitchens and bathrooms, and keep the splashback zones behind the hob and sink tiled rather than papered.
