Flooring Calculator for a Whole House
Estimate flooring for a whole-house install.
Buy all whole-house flooring from the same production run — mixing lots creates visible color banding. Add 10% waste for open floor plans, 12–15% if hallways and small rooms break up the layout. Save 3–4 extra boards after install for future repairs.

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 2,000 sq ft house?
2,000 sq ft plus 12% waste = 2,240 sq ft. At 22 sq ft per box, that's 102 boxes — order 105 to have leftovers for repairs.
Same flooring throughout the whole house?
It's the modern preference — makes the space feel larger and eliminates transitions. Keep bathrooms and laundry rooms on tile or waterproof LVP.
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.
