Pet urn size guide: scale comparison between small and medium ceramic memorials.

How to Choose the Right Urn Size? (A Simple Guide)

Choosing a final resting place for a beloved companion is a deeply personal task. One of the most common questions we receive at Mira Ceramics is: "How do I know if the ashes will fit?"

The Golden Rule: 1 lb = 1 Cubic Inch

The standard rule in the memorial industry is straightforward: one pound of a pet’s (or person’s) healthy body weight equals approximately one cubic inch of remains.

Example: If your faithful dog weighed 30 lbs, you will need an urn with a volume of at least 30 cubic inches.

Mira Ceramics Size Guide

To make your choice easier, we have categorized our handmade ceramic urns into two main sizes:

Pet/Use Average Weight Recommended Urn Size
Pocket Pets (Hamsters, Birds) Up to 5 lbs 5 cu. in. (Mini/Keepsake)
Standard Cats 8 – 15 lbs 18–45 cu. in. (Small/Medium)
Small to Medium Dogs 15 – 45 lbs 18–45 cu. in. (Small/Medium)
Sharing a Memory Token amount 5 cu. in. (Mini/Keepsake)

What if I am "Between" Sizes?

If your pet was exactly 45 lbs, or if you are unsure of the exact weight, we always recommend choosing the larger size. It is much better to have a little extra space than to have an urn that is too small. You can always place a small memento, like a lock of fur or a collar, inside alongside the remains.

The Concept of "Sharing" or "Keepsake" Urns

Sometimes, families choose to divide a loved one's ashes among several relatives. In this case, our 5-cubic-inch mini urns are the perfect choice. They are designed to hold a "token" portion of remains, allowing everyone to keep a beautiful, hand-painted piece of memory in their own home.
