Measure every wall
Use the greatest wall height. For a rectangular room, enter length and width; for an accent wall, enter just its width. All lengths here are metric.
PLAN BEFORE YOU PASTE
Beautiful walls. Clear numbers.
Find out how many wallpaper rolls to buy. See where each drop comes from, how the pattern matches and what remains.

Your walls, drop by drop
Each number identifies a drop in the cutting plan. The last drop on each wall is trimmed to width. Pattern marks are schematic.
Roll cutting plan
Read from left to right: pattern alignment, numbered drops, then the remainder. Scroll to inspect details.
▨ Pattern alignment■ Drop□ Remainder
The plan cuts drops in wall order, aligning each start to the repeat. Half-drop matching alternates phases 0 and ½ repeat on each wall. Every new roll is assumed to start at phase 0; the actual printed starting point may need an extra alignment cut. Check the label and installer guidance before buying. Offcuts and roll remainders are not reused. Extra rolls are shown separately.
Why counting drops matters
Area alone cannot tell you how many full-height drops fit into a roll. A small increase in wall height or pattern repeat can mean buying another roll.
Read the roll label
Copy the physical roll width and length, repeat and matching type. Presets only change dimensions; verify the pattern settings yourself.
Review the cutting plan
Follow the numbered drops and add spare rolls for damage or initial pattern alignment. Buy rolls from the same batch.
Before you buy
Why are windows and doors not subtracted?
Openings do not always save a full drop. This estimate keeps full-height drops so that an area deduction does not understate the roll count. Large openings require a separate installer cutting plan.
What is a pattern repeat?
The vertical distance after which the pattern repeats. Straight matching aligns adjacent drops at the same phase; half-drop matching shifts every other drop by half a repeat.
Does this calculate paste or labour?
The price estimate covers wallpaper only. Paste consumption depends on the adhesive and surface. Murals, A/B rolls, horizontal hanging and uneven walls need a separate plan.
