Use the Tile Calculator
Estimate individual tiles and full boxes from tiled area, tile size, waste and box quantity.
Calculations happen locally in your browser. ToolLott does not send these inputs to a server for this tool.
Material quantities are estimates. Confirm site dimensions, openings, product sizes, density, waste factors and supplier pack/stock details before ordering.
How to use it
Measure the job, replace the defaults with the actual product/site values, then calculate. The allowance is explicit so you can match your own project practice.
How the Tile Calculator works
Estimate individual tiles and full boxes from tiled area, tile size, waste and box quantity.
Calculation breakdown
ToolLott will explain the current inputs and displayed result here.
Tile calculation
Tile quantity uses tile face area and required floor/wall area including waste, then converts tile count to whole boxes.
tiles = ceil(area x (1+waste) / tile_face_area); boxes = ceil(tiles / tiles_per_box)ToolLott evaluates the relationship using the entered units and full numeric precision before display rounding.
| Symbol / input | Meaning | Unit |
|---|---|---|
area | Tiled area (m²) | user input |
tileLength | Tile length (mm) | user input |
tileWidth | Tile width (mm) | user input |
waste | Waste allowance (%) | user input |
perBox | Tiles per box | user input |
Step-by-step method
- Convert tile dimensions to metres and calculate one tile face area.
- Apply waste to the tiled area and divide by tile face area.
- Round up tiles, then divide by tiles per box and round boxes up.
Worked example
Ethan, a construction estimator preparing a material take-off, has 32 m² to tile using 600 × 300 mm tiles sold 8 per box, and wants 10% extra for cuts and future replacements.
Example inputs
- Tiled area (m²): 32
- Tile length (mm): 600
- Tile width (mm): 300
- Waste allowance (%): 10
- Tiles per box: 8
Calculation / processing
Tile face area = 0.6 x 0.3 = 0.18 m².Required area = 32 x 1.10 = 35.2 m²; 35.2 / 0.18 = 195.56, so 196 tiles.196 / 8 = 24.5, so 25 boxes.
The result is a planning quantity based on the entered dimensions, coverage/density values and allowance. Procurement should use current product data and site measurements.
Assumptions
- Geometry is represented by the simple dimensions entered in the tool.
- Coverage, density, stock size and waste/allowance inputs are project-specific values supplied by the user.
Limitations
- Irregular geometry, installation details, breakage, joints, laps, openings or supplier pack rules can change the actual order quantity.
- This is a quantity estimate, not structural/design certification or a substitute for drawings, specifications and supplier data.
Common questions
Why does ToolLott round some quantities up?
Items sold as whole boards, sheets, packs, boxes or panels cannot normally be ordered as fractions, so the tool rounds those purchase quantities upward.
Should I always use the default waste allowance?
No. Use an allowance appropriate to the material, layout, cutting pattern, site conditions and supplier guidance.
Can I use the result as a purchase order quantity?
Use it as a planning check, then confirm dimensions, product coverage/density and supplier pack sizes before ordering.
Methodology sources
This page uses basic mathematical or ToolLott implementation logic that does not require an external factual source. The worked result is still tied to the production tool and QA example.

A realistic way Ethan could use this tool
Ethan is a construction estimator preparing a material take-off.
Ethan has 32 m² to tile using 600 × 300 mm tiles sold 8 per box, and wants 10% extra for cuts and future replacements.
They use the worked values shown in the tool: Tiled area (m²): 32; Tile length (mm): 600; Tile width (mm): 300; Waste allowance (%): 10; Tiles per box: 8.
ToolLott returns “Tiles required: 196 (25 boxes)”. That gives Ethan a concrete figure to check against the real task before they copy it into the next document or decision.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
What this calculator is for
Use it to estimate individual tiles and full boxes from tiled area, tile size, waste and box quantity.
It sits within ToolLott’s Construction collection, where you can also estimate materials and quantities for asphalt, blocks, bricks, concrete, decking, drywall, fencing, flooring, gravel, insulation, tiles and timber.
