Our Cremation Urns – Size Selector

Our urn size selector instantly calculates the size of the urn needed. This calculation is based on the nationally accepted 1lb = 1 cu. in. formula, which leaves a safe amount of leeway. Volume of remains varies based on equipment & procedure, please adapt our calculations to your own.

Are we missing a cat or dog breed on our weight list? Please contact us and we’ll add them to our list. If we are missing an important volumetric measurement such as pints or other, please let us know.

We would appreciate any crematoriums who would be willing help us craft a better cremains calculation. If we can get a couple crematoriums in the pet cremation industry to submit their personal calculations, we can average those “weight to cubic inch” calculations and provide a more helpful tool.

We hope this page is a useful resource, let’s make it even better!
