Formula and method
Worked example
With room length = 15 ft, room width = 12 ft, waste = 10 %, coverage per box = 20 ft², price per ft² = $3.5, the Flooring Calculator returns flooring to buy: 198.0 ft²; boxes: 10; estimated cost: $700.00.
Tips for better results
- Add 5–15% for waste, cuts and breakage depending on the material.
- Measure twice and round up when buying — returns are easier than second trips.
- Coverage figures vary by product, so check the label or spec sheet.
⚠️ Material estimates are approximate. Follow local building codes and manufacturer instructions.
