Estimating the amount of Chavant clay you need for a project can be challenging. The calculators below can help you determine how much clay to buy for your project. Start from the Volume & Surface Calculator to estimate your project needs, then use the Volumetric Yield and Linear Coverage calculators to determine how much clay area or volume a particular clay covers.

Volume & Surface Area

Use this tool to help calculate how much volume or surface area your project has.


Determine how much volume a block, billet, bar or wedge of clay fills.
