Using these tools

Updated 6 October 2026.

Planning estimates

Use these tools to help plan quantities. Results depend on the dimensions and product specifications you enter. They are not a guarantee that a particular purchase will be sufficient.

Check before buying or cutting

Confirm your measurements, product coverage, roll dimensions, batch information and bag volumes with the supplier. Follow the manufacturer’s instructions. Surface condition, layout choices, cutting errors and material behaviour can change what you need.

Scope

The paint tool models rectangular rooms using one shared paint specification. The wallpaper tool supports free and straight matches only. The garden tool estimates volume and does not convert it into weight. Tiles and flooring use area estimates rather than cutting layouts. Concrete uses the selected mixed yield per bag. Decking counts surface boards without offcut reuse. Fencing models open runs with site-built picket infill, not fixed panels. None of these tools supplies structural, electrical or other professional installation advice.

Free access and changes

The tools are currently free to use without an account. Features, example values and methods may change as the tools are improved. Review the displayed assumptions each time you use a result.

Please use the calculators for ordinary project planning and avoid automated traffic that disrupts other visitors.
