This free flooring calculator works out how much flooring to buy for 1 room or several, with extra for cuts and the number of boxes.
It works for any floor sold by area: laminate, vinyl plank, hardwood, engineered wood or carpet tiles.
I built it because the floor's area is never the amount to buy. Cuts at the walls and a few spares push it up.
Here's how it works, a worked example, and how to pick the extra.
TL;DRKey takeaways
What is a flooring calculator?
A flooring calculator turns a room's size into the amount of flooring to buy.
It adds extra for the boards you cut at the walls, and counts the boxes.
How it works
The math is the floor's area, plus your extra, divided by what a box covers.
A worked example
Here's the example the calculator loads: a 15 by 12 foot room, 10% extra, and boxes of 20 square feet.
15 × 12 = 180 square feet. 180 + 10% = 198 square feet. 198 ÷ 20 = 9.9, so 10 boxes.
How to pick the extra
The calculator lets you set the extra, because it depends on the room and the layout.
The installation guide for your flooring gives the maker's own figure, so start there.
Mistakes to avoid
These are the slips that come up most.
- Buying exactly the floor's area, with nothing for cuts
- Forgetting closets and the floor under doorways
- Rounding the boxes down instead of up
Who is the flooring calculator for?
It's for anyone laying a new floor, and these tools help around it.
