- Australian builders, tradespeople, and DIY renovators
- Worth noticing
- Calculators use Australian sizes and metric units; users can edit variable inputs such as paint coverage and bag yield.
Field notes
The calculators accept job dimensions and show a scale drawing alongside the quantity estimate and its working. Inputs can reflect product-specific details, such as paint coverage or bag yield, rather than relying only on fixed assumptions. Coverage includes trade and garden tasks; the site cautions users to check sizes and quantities with a supplier before ordering.
