What Is a Laminate Flooring Calculator?
A laminate flooring calculator estimates how many boxes of laminate planks you need for a room using the coverage printed on each box. It applies a waste factor for cuts and plank staggering. It is the go to tool for homeowners buying laminate, since the material is sold in whole boxes with a labeled square footage.
How It Works
Boxes = ceil((Room Area × (1 + Waste ÷ 100)) ÷ Coverage per box).
Example
A 12 ft × 10 ft room with 10% waste and 20 sq ft boxes: 132 ÷ 20 = 6.6 → 7 boxes.
How to Calculate
- Measure the length and width of the room in feet. A 12 by 10 foot room is 120 square feet.
- Add a waste factor, typically 10 percent for a straight staggered layout. Multiply 120 by 1.10 to get 132 square feet to order.
- Check the coverage per box on the carton, often 20 square feet.
- Divide the square footage to order by the box coverage. One hundred thirty two divided by 20 is 6.6 boxes.
- Round up to a whole number of boxes, so order 7 boxes for this room.
Laminate Box Coverage by Common Plank Style
| Plank Style | Coverage per Box |
|---|---|
| Narrow 7 in planks | 15 to 18 sq ft |
| Standard 7.5 in planks | 20 sq ft |
| Wide 9 in planks | 22 to 25 sq ft |
| Long format planks | 25 to 30 sq ft |
| Bulk cartons | 30 to 40 sq ft |
