How to measure your wall

A made-to-measure Wallnia wallpaper is printed to the exact size of your wall. For a perfect result, all you need is to measure carefully: allow 10 minutes, a tape measure and a pencil. Here is the simple method we recommend.

What you need

  • A tape measure (ideally a 5 m metal one)
  • A pencil and a sheet of paper to note the measurements
  • A stepladder for tall walls
  • If possible, a second person to hold the tape

Measure in 3 steps

  1. Measure the width of the wall at three heights: top, middle and bottom. Walls are almost never perfectly straight: keep the largest of the three values.
  2. Measure the height in three places: left, centre and right, from the floor (or the top of the skirting board) to the ceiling. Again, keep the largest value.
  3. Add a 5 cm margin to the width and the height. This margin makes up for small irregularities in the wall and ceiling; it is trimmed off with a cutter during hanging.

Example: you measure 318, 320 and 319 cm wide, and 249, 251 and 250 cm high. You keep 320 × 251 cm, then add the margin: you order 325 × 256 cm.

Entering your measurements on the product page

On each wallpaper, enter the width and height (margin included) in the calculator. The area, the number of 50 cm strips and the price appear instantly. Then click the preview to see the design on your wall and choose the framing: that is exactly the framing we print.

Doors, windows, sockets and radiators

Do not subtract them. Order for the full wall area and cut out on site with a cutter: the design then flows continuously around the openings, like a real mural.

Special cases

  • Sloping or attic wall: measure the width at floor level and the greatest height, as for a rectangular wall. The excess in the slope is trimmed when hanging.
  • Several walls: measure and order each wall separately. For a design that continues from one wall to the next, contact us before ordering.
  • Very wide wall: no problem, the wallpaper is delivered in numbered 50 cm wide strips, whatever the width of the wall.
  • Small area: the minimum order is 1.5 m².

Mistakes to avoid

  • Measuring only once: always take three measurements.
  • Forgetting the 5 cm margin.
  • Rounding down: when in doubt, always round up to the next centimetre.
  • Mixing up width and height in the calculator.
