Floor Calculator
Estimate floor quantity, waste, and budget based on room and plank size.
What is Floor Calculator
Size a flooring order in one pass: enter room and plank dimensions, a waste percentage and a doorway width, and get the plank count, floor area, a skirting-board length that already subtracts the door opening, plus a materials-and-labour cost total. All local, instant.
How to use Floor Calculator
- Enter the room length and width
- Enter plank size, door width and your waste rate
- Optionally add material and labour prices, then read the totals
Frequently asked questions
What waste rate should I use?
Straight-lay rectangular rooms usually need 5–8%; diagonal or herringbone layouts can waste 12–15%. The field is editable because offcut reusability depends on your room shape.
How is the skirting estimate calculated?
Perimeter minus the door opening you entered — 2 × (length + width) − door width. Measure wardrobe or hallway gaps separately if you want it exact.
Does the result include underlay or accessories?
No — it covers planks, skirting length and the material/labour costs you enter. Underlay, thresholds and trims are not modelled, so budget them separately.
