Flooring Calculator for a Living Room
Estimate boxes of flooring for any living room.
Living rooms are typically the largest room in the house and often flow into adjoining spaces — measure the whole continuous run so board colors and lot numbers match. Add 10% waste for a straight-lay pattern or 15% for diagonal or herringbone layouts.

How does the flooring calculator work?
Multiply room length × width to get square footage, add a 10% waste allowance, and divide by the box coverage printed on the manufacturer label.
What else do people ask about this calculator?
How much flooring for a 15×20 living room?
A 15×20 ft (300 sq ft) living room needs about 330 sq ft with 10% waste — roughly 15 boxes if each box covers 22 sq ft.
Same flooring in living room and hallway?
Yes — running the same flooring through connected spaces makes the whole area feel bigger. Just make sure you buy enough from the same dye lot to avoid color banding.
How much waste for hardwood flooring?
10% is standard for straight installs; add 5% more for diagonal, complex patterns, or rooms with many angles.
How many square feet in a box of laminate?
Typically 20–30 ft² per box. Check the box — it's the most reliable number for your specific product.
