Plan tile installation with project-specific quantities instead of a broad rule of thumb. This calculator turns your measurements and assumptions into a clear main estimate, shows the supporting figures, and makes rounding or timing assumptions visible. Use it for early budgeting and quote comparison, then confirm measurements, product coverage, labor scope, and site conditions before ordering materials or scheduling work.
The result is a planning estimate for tile installation, based entirely on the values entered. It is most useful for checking scope, comparing quotes, and identifying which assumption deserves better measurement.
This tool does not replace a site inspection, manufacturer instructions, code requirements, or a written contractor quote.
A 12 × 24 inch tile covers 2 sq ft. For 180 sq ft plus 10% waste, the project needs 99 tiles. At 12 tiles per box, buy 9 boxes.
No. It uses nominal tile face dimensions. For most purchasing estimates, the waste allowance is more important, but verify manufacturer box coverage for the exact product.
Tiles cannot be purchased fractionally, and boxes are normally sold as whole units. Each rounding step keeps the order from falling short.
Use the best project-specific values available. Contractor measurements and written quotes usually produce a more useful planning estimate than broad averages.
Only when those costs are represented by an input. Add local taxes, delivery, permits, disposal, and other omitted charges before making a final budget decision.
Yes. Decimal entries are supported where they make sense, and calculations keep full precision until the displayed result is formatted.
| Variable | Conversion |
|---|---|
| Tile face area | width × length ÷ 144 |
| Base tile count | surface area ÷ tile area |
| Adjusted tile count | base count × waste factor |
| Box count | ceiling(adjusted tiles ÷ tiles per box) |
