Field notes
The listed tools distinguish geometry-based estimates from calculations tied to a product label or supplier coverage. Examples include estimating whole flooring packs from the coverage on a selected pack and calculating mortar bags from the number of specified units a bag will lay. Several tools also state their limits, including a roof-area estimate based on one rectangular horizontal projection.
