Measure every rectangle
Keep separate walls or floor sections as separate rows so their source dimensions remain reviewable.
A transparent area-based estimate
Know how many tiles and boxes your measurements imply.
Add rectangular surfaces or enter a known area, choose tile dimensions, then set the extra percentage yourself. TileCalc rounds to whole tiles and, when supplied, whole boxes. It runs in your browser and does not pretend to model cuts, joints, patterns, obstacles, offcuts, or installer decisions.

Three explicit steps
Measure, define the tile, then choose the extra
Enter tile face dimensions
Use the width and height printed for the selected product; thickness is irrelevant to this area estimate.
Choose and record the extra
Enter a percentage that fits your plan and advice; TileCalc never inserts a universal hidden recommendation.
Useful for a first quantity check
One formula, several ordinary surfaces
- For floors, add rectangular sections separately when the room is not one clean rectangle.
- For walls and backsplashes, record every measured panel and decide explicitly whether openings are excluded.
- For box planning, supply the exact pieces-per-box label to see the unavoidable whole-box rounding.
