Tile Layout Calculator
Enter the span, tile size, and grout joint. MeasureMarks compares the two standard centered layouts and recommends the one with the better balanced edge cuts.

Grout-joint center marks
Measured from the starting edgeHow MeasureMarks chooses the layout
A centered tile layout can be centered either on the middle of a tile or on the middle of a grout joint. Both are symmetrical, but they can produce very different border cuts. MeasureMarks calculates both and favors the layout with the larger usable edge cut while checking your preferred minimum.

Choose the better centered tile layout before setting the first tile
A centered tile job can be centered on the middle of a tile or on the middle of a grout joint. Those two choices produce different border cuts. This calculator compares both arrangements and recommends the one that gives the larger, more balanced edge pieces.
What the calculator considers
Enter the total layout span, actual tile width, grout-joint width, and the minimum edge cut you would prefer. MeasureMarks builds both centered patterns, calculates the visible cut at each edge, and shows the grout-joint center marks for the recommended layout.
Before installation
- Use actual tile dimensions; nominal tile sizes can differ from measured dimensions.
- Include the grout joint in the layout because every joint changes the repeating module.
- Dry-lay or verify several tiles when variation in manufactured tile size is significant.
- Allow separately for movement joints, perimeter gaps, trim profiles, or substrate conditions required by your installation method.
Does this replace a dry layout?
No. It gives you a strong starting plan, but real tile variation and room conditions should still be checked on site.
Why might the recommended edge cut be below my minimum?
The fixed span and tile module may make your preferred cut impossible without shifting the layout or changing materials.
