Accurate flooring calculations prevent shortages and minimize waste. This calculator determines material quantities for any room, accounting for cutting waste and installation factors.
Waste factors vary by floor type and room complexity. Add 5% for simple rectangular rooms with vinyl or laminate. Add 10% for wood flooring, tile, or rooms with angles. Diagonal or pattern installations require 15% waste. Complex rooms with many obstacles need 20% extra.
Measure each room's length and width at the longest points. For irregular rooms, divide into rectangles, calculate each section, and sum totals. Subtract large permanent fixtures like islands but not removable appliances.
Most flooring is sold by the square foot or in boxes covering specific areas. Vinyl planks typically come in boxes of 20-24 sq ft. Hardwood varies widely. Always order from the same lot as colors vary between production runs.
Quick Tips
- Always order 10-15% extra materials for waste
- Check local building codes before starting
