How to use the Tile Calculator
Estimate tile count from surface dimensions, tile size, pattern allowance, grout spacing, and waste. It includes Known total area, Multiple rectangular areas workflows, so choose the one that matches the values you actually know. Use it to check a practical estimate, paying close attention to the selected units and assumptions.
Step by step
- For the Tile, enter total area, area unit, area 1 length, area 1 width, area 2 length. Keep each value in the unit displayed beside its field.
- Review the selected Tile workflow and inputs, then read tile required in the result panel.
- Change one Tile assumption at a time to compare scenarios. Use Reset to restore this tool's worked example values.
How the calculation works
Area is divided by the installed tile module (tile plus grout gap), increased for waste, and rounded up to whole tiles and boxes. Supports yard/inch/centimeter area and dimensions plus per-tile, box, or area pricing.
Worked example
In the Tile worked example, total area 120 ft², area unit Ft², area 1 length 12 ft, area 1 width 10 ft produces tile required of 87 tiles. Area 120.00 ft². Review the displayed units before comparing the result.
Understanding the result
The Tile reports tile required. Use it to check a practical estimate, paying close attention to the selected units and assumptions. Check the entered units and assumptions before using the result for purchasing, construction, engineering, or safety decisions.
How to check the answer
Check the Tile result by reversing the conversion or recomputing tile required from total area, area unit, area 1 length. For construction, electrical, weather, or purchasing decisions, compare the result with the applicable specification or professional guidance.
Common questions
What does the Tile calculate?
Estimate tile count from surface dimensions, tile size, pattern allowance, grout spacing, and waste.
Which Tile inputs have the biggest effect?
tile required responds directly to total area, area unit, area 1 length, area 1 width, area 2 length. Change one input while holding the others constant to see its effect.
Is the Tile result exact?
Check the entered units and assumptions before using the result for purchasing, construction, engineering, or safety decisions. Recheck total area, area unit, area 1 length and use tile required only for a decision where that level of precision is appropriate.
