Tile Calculator

What you will get

1. Needed

See the estimated project quantity from your measurements.

2. Buy

Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.

3. Check

Review product coverage, site conditions, local requirements and supplier details before ordering.

Quick answer: Calculate floor or wall tile quantity from room dimensions and tile size with waste. Start with actual measurements, use the product label for coverage or yield, and treat the result as a planning estimate until site conditions and supplier requirements are confirmed.

Estimate tile count for a rectangular floor or wall, including cutting waste.

Enter dimensions and calculate.

Tile area is converted to square feet before dividing the project area. Always round up to whole tiles/boxes and follow the manufacturer's box coverage.

Diagonal layouts and rooms with many cuts generally need more waste than a simple rectangular layout.

Practical planning notes

How to use this Tile Calculator | Tiles & Waste

Calculate floor or wall tile quantity from room dimensions and tile size with waste. Start with the actual dimensions or load values from the project, keep the units consistent, and change the default assumptions when the product label or supplier sheet gives you a more accurate value.

What the estimate does and does not include

This page is for early material planning. The result can change with openings, layout, cuts, waste, product yield, density, packaging, access, installation method and site conditions. It does not replace structural design, permitted drawings, manufacturer instructions or a contractor quotation.

Worked planning example

For a simple project, enter one measured section first and review the result. If the shape is irregular, split it into smaller sections, calculate each section, and add the quantities before applying whole-bag, box, bundle or delivery rounding.

Before you order

  • Re-check the field measurements and the unit labels.
  • Replace generic coverage, yield, density or spacing assumptions with the exact product data.
  • Confirm package size, minimum order, delivery, tax and local requirements with the supplier.
