How to read urn capacity

Use the capacity that the store states. A product's outside dimensions do not tell you its capacity.

Start with the maker's rule.

Spirit Pieces states that about one pound of body weight equals one cubic inch of cremated remains.

This is a general estimate. Ask the crematory or the store about the capacity that you need.

A keepsake urn holds a small portion of remains. It may not hold all the remains.

Read the store's stated capacity and use. Ask the store before you choose a companion or keepsake urn.
