Laminate Flooring Calculator
Laminate flooring is a DIY-friendly option that floats over the subfloor without nails or glue. Enter room dimensions, box coverage (typically 20–22 sq ft), and waste percentage to get your box count. Add underlayment unless the product has a pre-attached foam backing.

Frequently Asked Questions
How many boxes of laminate do I need for a 14×11 room?
A 14×11 room is 154 sq ft. With 10% waste, you need 170 sq ft of laminate. At 22 sq ft per box, that's 8 boxes. Round up — returning unused boxes is almost always possible, but running short mid-project means a second trip and possible dye-lot mismatch.
Do I need underlayment under laminate flooring?
Yes, unless the laminate has pre-attached foam backing. Underlayment provides sound dampening, slight cushioning, and a moisture vapor barrier. A 2-in-1 underlayment with a vapor barrier is recommended over concrete subfloors.
