European Wallpaper Roll Calculator

Metric-first, with European roll sizes as the default. Metres and centimetres in, rolls and square metres out, nothing converted in your head.

Sheet 7 of 9

Centimetres end to end, with European roll sizes as the default. Nothing is converted to inches and back. Working in feet? Sheet 1.

Euro rolls are singles, not US doubles. The repeat is entered in centimetres, as labels print it.

Each drop allows 10 cm of trim, 5 cm at the ceiling and 5 cm at the skirting.

Estimate only. Check the roll label for its true width and length, confirm the repeat, and buy every roll from one dye lot.

Your walls, in drops

Metric first, not converted

This is a European wallpaper roll calculator rather than an imperial one with a conversion bolted on. Most calculators that claim to handle metric convert your metres into inches, do the arithmetic, and convert back. That works, but it rounds twice and it presents Euro roll sizes as awkward decimals. This sheet works in centimetres throughout, so 53 cm is 53 cm and a 10 m roll is 1000 cm.

Listings usually write the sizes closed up, as 53cm x 10m or 52cm x 10m, and some use the US spelling "meters" for the same thing. The defaults reflect European practice: a 53 cm × 10 m roll, 10 cm of trim per drop, and the repeat entered in centimetres as labels print it. A 2.5 m wall plus trim is 2.6 m, which a 64 cm repeat rounds up to 3.2 m, so three drops come off a 10 m roll and 40 cm is left. That rounding is worth seeing: the same wall on a plain paper takes a 2.6 m cut and still yields three, but at 2.4 m it would have yielded four.

If your measurements are in feet and inches, the imperial sheet is the one to use. If you are trying to understand why the two systems produce different-looking roll sizes for the same wall, the metres vs feet guide sets them side by side.

How the metric sheet works

  1. Measure in metres and centimetres

    Each wall width and the ceiling height. The ticket takes metres and centimetres separately so you can type what your tape shows.

  2. Use the Euro roll presets

    53 cm × 10 m is the most common size, with 52 cm × 10 m close behind. Type a custom size if your range differs.

  3. Enter the repeat in centimetres

    European labels print the repeat in centimetres, often as "Rapport". Enter it as printed; the sheet does the rounding.

  4. Read rolls and square metres

    The count is in whole rolls. The readout also gives the wall area in square metres, which is what a decorator quoting by area will ask for.

European roll coverage

Drops from one roll at three common wall heights, allowing 10 cm of trim, for a plain paper and for a 64 cm straight repeat.
RollAreaWall 2.4 m: plain / 64 cm repeatWall 2.5 m: plain / repeatWall 2.7 m: plain / repeat
53 cm × 10 m5.3 m²4 / 33 / 33 / 3

53 cm × 15 m7.95 m²6 / 55 / 45 / 4
70 cm × 10 m7.0 m²4 / 33 / 33 / 3

The second number in each pair is the cost of a pattern. At a 2.4 m wall a plain paper gives four drops from a 10 m roll and a 64 cm repeat gives three, because the cut rounds from 2.5 m up to 2.56 m. Roll width changes how many drops a wall needs, and roll length changes how many a roll gives, so the two columns move independently.

Questions people ask

How long is a 10 metre roll of wallpaper?

Ten metres, which is 32 ft 10 in. At a 2.5 m wall height plus 10 cm of trim, a plain paper needs a 2.6 m cut and the roll gives three drops with 2.2 m left over. With a 64 cm repeat the cut rounds up to 3.2 m and the roll still gives three, with 40 cm left. At a 2.4 m wall the plain paper gives four.

How many metres is a roll of wallpaper?

The European standard is 10 m long by 52 or 53 cm wide, which is about 5.2 to 5.3 square metres of paper. Some ranges sell 15 m or 20 m rolls, and hand-printed papers vary more. The label is the authority.

How many metres of wallpaper do I need?

Multiply the number of drops by the cut length. The readout above gives that as well as the roll count, so you can check it against a supplier quoting in metres rather than rolls.

How does a wallpaper calculator work in metres?

Identically to one in feet, with the units swapped. Drops = wall width ÷ roll width, rounded up. Cut length = wall height + trim, rounded up to a whole pattern repeat. Drops per roll = roll length ÷ cut length, rounded down. Rolls = drops with waste ÷ drops per roll, rounded up.

What is the standard wallpaper roll length in metres?

Ten metres across most of Europe, paired with a 53 cm width. The 52 cm width also appears, and the difference is small enough that some suppliers list them interchangeably even though they are not.

How many square metres does a wallpaper roll cover?

A 53 cm × 10 m roll holds 5.3 m², and a 52 cm × 10 m roll holds 5.2 m². Usable coverage is lower because each drop is cut to length, which is why this sheet counts drops rather than dividing area by coverage.

Should I use the metric calculator or the main one?

Use this one when your wall measurements and your roll label are both metric. Use the main sheet when they are in feet and inches. Mixing units by converting in your head is where mistakes creep in; both sheets run the same engine.

What is the difference between metric rolls and US double rolls?

A European 10 m roll is a single roll sold as a single roll. A US double roll is two single rolls packaged together but priced by the single. The lengths are similar (10 m is 32.8 ft; a US double is often 27 or 33 ft), but the pricing conventions are not. The metres vs feet guide covers both.
