What this calculator does
Turns room dimensions into the square footage, boxes or planks you need to buy, with a waste allowance sized to the install pattern.
When to use it
- Buying laminate, LVP, hardwood or tile for a room.
- Comparing box sizes across brands.
- Planning transitions across multiple rooms.
Common mistakes
- Buying by room area instead of box coverage — you'll come up short.
- Skipping the underlayment and moisture barrier from the budget.
- Ignoring the direction of planks when calculating cuts.
Pro tips
- Add 10% waste for straight lays, 15% for diagonal or herringbone.
- Buy from the same dye lot to avoid color mismatches.
- Acclimate flooring 48 hours before install.
