Flooring Quantity Calculator

Never buy the wrong amount of flooring again. This calculator accounts for room dimensions, box coverage, and a built-in waste factor to ensure you have enough material for cuts and mistakes.

How to Use This Tool

  1. Enter the room length and width in feet.
  2. Check your flooring box for coverage in square feet (typically 15-25 sq ft per box).
  3. Set waste factor: 10% for straight lay, 15% for diagonal, 20% for complex patterns.
  4. Click Calculate to see total boxes needed.

The Formula

Boxes = (Room Area / Box Coverage) + Waste. Standard waste factor is 10% for straight installation and 15% for diagonal. Complex patterns may require 20% waste.

Why It Matters

You are laying hardwood in a 15x12ft bedroom (180 sq ft). Planks cover 24 sq ft each — you need 8 packs. Add 10% for cuts: order 9 packs. Nail-down installation needs 10d finish nails at ~2 per plank.
