Laminate Flooring Calculator
You need your room's square footage, plus 10% for waste, divided by the coverage of one box. Enter your room size and the box coverage to get boxes and cost.
How to measure for laminate
Multiply room length by width for the area, then add 10% for cutting waste. Measure into closets and doorways where the floor continues, and total irregular rooms with the square footage calculator.
Waste and layout
Plan 10% extra for a straight lay and 15% for diagonal patterns. Longer rooms and wide planks generate more offcuts. The first and last rows almost always need ripping to width.
Cost
Multiply boxes by the price each. Laminate runs $1–$5 per square foot for the planks. Comparing to a waterproof option? See the vinyl flooring calculator.
Frequently asked
How many boxes of laminate do I need?
Find the room area, add 10% for waste, then divide by the square footage each box covers and round up to whole boxes.
How much extra laminate should I buy?
Add 10% for a straight install and 15% for diagonal layouts. Keep one box back for repairs, since patterns change between production runs.
Can I install laminate over my existing floor?
Often yes — laminate floats over a flat, dry subfloor with an underlayment. It does not change the quantity you need, which is based on floor area.
