Flooring & TileVinyl Plank Flooring Calculator — How Much LVP Do I Need?
Enter your room’s length and width to get the vinyl plank (LVP) flooring to buy — the floor area plus a 10% waste allowance for cuts and the random plank layout.
How this calculator works
We multiply length × width for the floor area and add 10% for cuts and the staggered plank pattern. Divide the “sq ft to buy” by your box’s coverage (often 18–24 sq ft) to get the number of boxes.
What changes how much you need
- Add 10% waste for straight layouts; use 15% for diagonal or herringbone patterns.
- Boxes commonly cover 18–24 sq ft — divide your total by the box coverage for the box count.
- LVP is waterproof and click-lock, so it floats over most flat subfloors and concrete.
- Let planks acclimate in the room 24–48 hours before installing.
Frequently asked questions
How much vinyl plank flooring do I need?
Measure length × width for the room area and add about 10% for waste. A 14×12 ft room (168 sq ft) needs about 185 sq ft of LVP.
How do I convert square feet to boxes?
Divide the “sq ft to buy” by the coverage printed on the box — often 18–24 sq ft — and round up.
How much extra vinyl plank should I buy?
About 10% for standard layouts, 15% for diagonal or herringbone. Keep a spare box from the same lot for future repairs.
