Was ist der Wallpaper Calculator?

Wallpaper is one of the trickiest materials to estimate because pattern repeats create a lot of waste — a 60 cm repeat can add 20–30% to your material needs. This calculator converts your room dimensions and roll specs into the exact number of rolls to buy, accounting for both pattern repeat and the number of usable strips per roll.

You may also find the Paint Coverage Calculator, Carpet Calculator, and Crown Molding Calculator useful.

Wer nutzt diesen Rechner?

This tool is used by homeowners wallpapering a room, interior designers specifying feature walls, and decorators quoting renovation jobs.

Verwendung the Wallpaper Calculator

  1. Geben Sie Room perimeter ein.
  2. Geben Sie Wall height ein.
  3. Geben Sie Roll length ein.
  4. Geben Sie Roll width ein.
  5. Geben Sie Pattern repeat ein.
  6. Klicken Sie auf Berechnen, um die Ergebnisse zu sehen.

Formel

The calculator uses the following formula:

Wall area = perimeter × height; Strips per roll = floor(roll_length ÷ (height + pattern_repeat)); Rolls = ceil(perimeter ÷ roll_width × strips_ratio)

Rechenbeispiel

A room with 14 m of wallpaperable perimeter, 2.5 m walls, using rolls that are 10 m long × 0.52 m wide with a 64 cm pattern repeat needs 11 rolls.

Schritt-für-Schritt-Berechnung

  1. Wall area: 16 m × 2.5 m = 40 m²
  2. Usable strips per roll: floor(10 ÷ (2.5 + 0.64)) = floor(10 ÷ 3.14) = 3 strips
  3. Total strips needed: ceil(16 ÷ 0.53) = 31 strips
  4. Rolls needed: ceil(31 ÷ 3) = 11 rolls

Häufige Fehler vermeiden

  • Ignoring the pattern repeat — a 64 cm repeat can waste an entire strip per roll
  • Buying based on wall area alone without factoring in usable strips per roll
  • Not buying extra for patching future damage (keep 1 roll in reserve)
Pro Tip: Buy all rolls from the same batch number — the number printed on the label. Different batches can have subtle colour differences that are invisible in-store but obvious on the wall.

Häufig gestellte Fragen

How do I calculate wallpaper for a room with a pattern repeat?
Each strip must be cut so the pattern aligns at eye level. This wastes the top or bottom of each strip. The usable length per strip = roll_length ÷ (ceiling_height + pattern_repeat). The calculator does this automatically.

What is a full drop versus half drop wallpaper pattern?
A straight (full) drop means every strip starts at the same point in the pattern. A half drop means alternate strips are offset by half the repeat height. Half drop patterns generate more waste and need more rolls.

How wide are standard wallpaper rolls?
Standard UK/European rolls are 52–53 cm wide. US rolls are typically 68 cm wide. Some designers offer 70–90 cm wide rolls. Always measure and geben Sie actual roll width — do not assume.

Can I wallpaper over existing wallpaper?
Not recommended. Old wallpaper may bubble or peel when new paste is applied, and the added weight can cause both layers to fall. Strip the old paper first for best results.

How long does wallpaper paste need to soak?
Most paste manufacturers recommend 3–5 minutes of soaking time on the pasted strip before hanging. Thicker wallpapers or those printed on non-woven backing may need longer. Over-soaking causes stretching.
