Frequently Asked Questions & Guide

How do you calculate the number of tiles needed?

Multiply length by width for the area, then divide by the coverage of a single tile (accounting for joint spacing width). Always add 10% to cover cuts and layout waste.

What is the standard spacing for floor tiles?

Standard floor tile spacer size is 1/8 inch. Larger tiles or uneven substrate may require larger joints (e.g. 3/16 inch or 1/4 inch) to prevent lippage.

Does this calculator account for tile cutting waste?

Our calculator reports both the base count and an estimated layout with 10% waste buffer. Complex patterns like herringbone may require a 15% waste allowance.
