Room material planning guides
Measure accurately, use the right specification and understand the quantities before buying. These worked examples can be repeated in the calculators.
How many flooring boxes for a 12 m² room?
A 4 × 3 m room with 90 × 15 cm planks: compare an area estimate, a laying plan and offcut reuse before choosing pieces and full boxes.
How to calculate wall panels and full packs
Estimate wall panels from usable dimensions, pieces per pack and reserve. A worked 4 × 2.7 m wall example with 70 × 77 cm panels.
How to calculate wallpaper rolls with a pattern repeat
Count full-height drops, trimming and straight-match repeats. See why enough square metres of wallpaper may still mean too few rolls.
How to measure an L-shaped or irregular room
Measure edges, avoid overlapping areas and draw a non-rectangular floor plan. Includes a 14 m² L-shaped example and measurement checks.
Reuse flooring offcuts with a cutting and assembly plan
Understand offcut reuse, match cut-piece IDs to the floor plan and export a PDF. Compare the same layout with and without reuse.
