Compare boards, pedestals, pavers, a concrete slab, tiles or gravel for the same footprint.

Plan a job with the right calculators
Each guide connects the useful estimates in working order, so you can keep the same dimensions and compare consistent quantities.
Choose a guide for your project
Start with the area to be covered, then open only the calculators that match the base and finish you intend to use.
Gravel drive: calculate each layer
Estimate excavation, geotextile and gravel without confusing loose depth with compacted finished depth.
Read guideTiling: from substrate to skirting
Calculate area, levelling compound, tiles, adhesive and skirting length for the same room.
Read guidePlasterboard partition: frame and finish
Estimate boards, tracks, studs, insulation and paint from the partition’s finished dimensions.
Read guideA simple method that avoids entering dimensions twice
Record the finished dimensions and substrate constraints first. Use those same measurements in each calculator, then save the useful alternatives in one project.
- Measure each separate area, opening or change in depth.
- Estimate the base first, then the finish and finally the consumables.
- Compare results using the same waste allowance and pack sizes.
