Urn Size Guide

Our guide to help you select the correct size Urn for your Pet Companion.

The recommended rule is you will need at least 1 cubic inch volume for each pound that your animal weighed / weighs.

For example, Pet Companion that weighs 20 pounds will need an urn with a minimum capacity of at least 20 cubic inches.

It is strongly recommended to have extra space in the Urn – just to err on the side of caution and make sure the ashes are contained properly.

Adding 10 cubic inches more is a good way to be sure that your Pet Urn will be large enough to hold the animal’s cremains. 

Therefor, if your dog weighed / weighs 20 pounds, shop for dog urns with 30 cubic inches of capacity or more.
