Floor Material Quantity Calculator
Calculate floor covering from a room length and width and a board or tile length and width in the same chosen unit. Add 0–100% user waste, round up to whole pieces, and optionally multiply by a user-supplied unit cost. This is pure covering arithmetic; it excludes patterns, joints, cuts, packaging, base construction, quotes, and tax.
A QUICK WALKTHROUGH
How to use this tool
- Enter the room length and width.
- Enter the board or tile dimensions and 0–100% waste.

GOOD TO KNOW
Common questions
Can I mix metres and feet?
No. Convert every length to the same chosen unit first.
How does waste affect the result?
Waste is added to the area ratio before the required piece count is rounded up.
Is unit cost required?
No. Leave it blank to calculate area and pieces only.
