Tile Layout Calculator

How to Use This Tile Calculator

Start by entering your room dimensions in inches or feet — the calculator accepts both. Next, set your tile size and grout spacing. Choose from over 10 layout patterns including straight grid, brick/subway offset, herringbone, and diagonal to see a live preview of your tiled surface. Full tiles appear in blue while cut tiles are highlighted in red, giving you a clear picture of where cuts are needed. For non-rectangular spaces, switch to advanced mode to build L-shaped, U-shaped, or T-shaped rooms. You can also add obstacles like outlets, windows, or drains so the calculator accounts for tiles around them. When you are satisfied with the layout, export a PDF material list or share a link with your tile supplier or contractor.
