Free Tile & Flooring Calculator – Tiles, Boxes & Cost

Tile Calculator Guide

The Tile Calculator estimates how many tiles and boxes you need for any flooring project. Enter your room dimensions, tile size, and waste factor to instantly see the number of tiles required, boxes to purchase, and estimated cost.

The waste factor accounts for cuts, breakage, and pattern alignment. Use 5% for simple straight layouts, 10% for standard installations, and 15% for diagonal or complex patterns. Always buy at least 10% extra to have matching tiles for future repairs.

Tile sizes vary widely — from small mosaic tiles (1×1 inch) to large format tiles (24×24 inches or larger). Larger tiles generally require less grout and create a more seamless look, but are heavier and harder to cut. Enter the exact tile dimensions from the product label for the most accurate calculation.
