Apply waste to area first
For a 20 m² floor with 10% waste, the working area becomes 22 m². Establish the adjusted area before converting it into material units.

FLOORING QUANTITY
Flooring purchase quantity guide
Divide by usable area per tile
A 600×600 mm tile covers 0.36 m². Dividing 22 m² by 0.36 gives about 61.11, so 62 tiles are required after rounding up.
Round up again for boxes
If 62 tiles are required and a box contains 12, the purchase quantity is 6 full boxes, not 5.17. Unit rounding and box rounding are separate steps.
Use usable installed area per box
Wood flooring packages differ in piece count and usable coverage. When the manufacturer provides installed area per box, that value is usually a better input than reconstructing coverage from nominal board dimensions.
Check roll width and cutting direction
The same floor area can require different roll lengths depending on roll width, room direction, seams, and cuts. Treat the area result as a first purchasing reference and verify the cutting plan separately.
Apply cost to the real purchase unit
Estimated cost should use rounded purchase units such as full tiles or boxes, not only the theoretical area. Delivery, accessories, and labor are separate.
IMPORTANT NOTES
Important notes
- Vinyl roll requirements can vary with width and cutting direction.
- Tile waste can vary with grout, cuts, and patterns.
- For wood flooring, area per box is recommended because package contents vary.
- Waste rate is a reference input and does not guarantee shortage or surplus.
- Estimated cost is based on your input price, not live pricing.
- Floor area received from TOOL083 is not deducted again.
FAQ
Frequently asked questions
01How many 600×600 mm tiles for 20 m² with 10% waste?+

02How many boxes for 62 tiles at 12 tiles per box?+
62÷12 rounds up to 6 boxes.
03What input is best for wood flooring?+
Use the usable installed area printed for each box when available.
04Can this determine exact vinyl roll cutting?+
No. The first version is an area-based reference; cutting direction can change actual rolls needed.
