Pet Urn Size Guide

Choosing the correct urn capacity is more important than choosing by external dimensions alone. The amount of ashes can vary with the cremation process, bone structure and the crematorium's handling method, so confirm the expected volume with your crematorium whenever possible.

Allow some spare capacity

Where your pet is close to the upper limit, select the next size up. Spare room can also be useful if you plan to include a collar tag, fur, a written note or another small keepsake.
