Flooring Calculator

Add rectangular areas that make up your room. For L-shaped or irregular rooms, add each section separately.

Calculation Method

The flooring calculator estimates the amount of material needed using these steps:

1. Room area = sum of all rectangular sections (length × width)
2. Waste area = room area × waste percentage
3. Total area needed = room area + waste area
4. Pieces needed = total area ÷ area per piece (tile or plank)
5. Boxes needed = pieces ÷ pieces per box (rounded up)

Waste Percentage Guide

• Simple rectangular room: 5–10% waste
• Standard layout: 10% waste (recommended default)
• Diagonal or herringbone pattern: 15–20% waste
• Complex room shape or many cuts: 15–20% waste
• Large-format tiles in small rooms: 15–20% waste

Flooring Type Notes

• Tile: Sold individually or by the box. Account for grout spacing (not included in area calculation). Larger tiles mean fewer cuts but more waste on edges.
• Hardwood: Sold by the box or square foot. Plank widths typically range from 2.25–5 inches. Allow material to acclimate 48 hours before installation.
• Laminate: Sold in boxes covering a specific area. Planks click together for floating installation. No glue or nails needed for most products.
• Vinyl: Planks or tiles are waterproof and work well in kitchens and bathrooms. Sold by the box or individually.
