Tile Calculator

This tile calculator estimates the number of tiles needed for a floor, wall, or custom area based on project dimensions and tile size.

It includes waste allowance for cuts, breakage, and layout complexity so you can plan a more realistic purchase quantity.

A 10 ft by 8 ft bathroom floor has 80 square feet of area. If each tile is 12 inches by 12 inches, each tile covers 1 square foot, so the base count is 80 tiles.

With a 10% waste allowance, the estimate becomes 88 tiles. If the layout is diagonal or has many cuts around fixtures, a 15% allowance may be more realistic.

Check tile boxes for batch, shade, and calibre information. Mixing boxes from different batches can produce visible colour or size differences.

Keep spare tiles for repairs because matching the exact tile later can be difficult once a style or batch is discontinued.

Use the calculator result as the material starting point, then check the parts of the project that affect the real order: access, delivery minimums, product pack sizes, batch matching, surface preparation, waste, and whether the work area is as square and level as it looks.

For a quick budget, multiply the adjusted quantity by the supplier price and add delivery, tools, fixings, disposal, and any preparation materials. Those extras can be the difference between a tidy estimate and a project that quietly runs over budget.

Homeowners can use it before visiting a supplier, landlords can use it when comparing repair quotes, and contractors can use it for quick early checks before producing a formal estimate. It is also useful when comparing two project options that use different materials.

The result should make conversations more specific. Instead of asking for "enough material for a room" or "a load for the driveway," you can discuss approximate quantities, waste allowance, delivery units, and where a professional measurement is still needed.

Measure consistently and avoid mixing inside dimensions, outside dimensions, and rounded estimates in the same calculation. Even a small measuring error can become expensive across a whole room, wall, driveway, or project area.

Do not round material quantities down. Allow for cuts, waste, breakage, overlaps, access constraints, and supplier pack sizes before ordering, especially when matching batches or finishes matters.
