とは何か Flooring Calculator?

▾

A flooring calculator estimates the number of tiles, planks, or square metres of flooring material needed for a room, including a waste allowance for cuts, breakage, and pattern matching.

PrimeCalcPro provides professional-grade tools trusted by businesses and academics.

方法 Flooring Calculator

▾

1Measure the room length and width to get total area (m² or ft²)
2Add 10% waste allowance for straight-lay patterns, 15% for diagonal or herringbone
3Divide total area by the area of one tile or plank to get unit count
4Calculate total cost by multiplying units × price per unit, plus fitting costs

解いた例

▾

例 1

入力:Room 4m × 5m = 20m² · 10% waste

結果:22 m² tiles needed

Order at least 22m² to allow for cuts

例 2

入力:250mm × 1500mm planks, 25m² floor + 10%

結果:73 planks

27.5m² ÷ (0.25×1.5m²) = 73.3

💡

プロのヒント

Always buy at least 10% extra and keep offcuts — if a tile cracks in future, matching an old batch is nearly impossible. Dye lots change between production runs.
