Size Guide for Urns

What size Urn do I need?

Understanding how much ash is left after the cremation process, can allow you to know what size urn is required. Therefore, we have created this size guide to help you find the correct sized urn for your loved one.

General info

The general rule is for every pound of body weight, allow one cubic inch of cremated remains. If you are measuring in Kilograms, the conversion is 1 Kilogram = 2.2 Pounds.

It is important to note that when choosing a cremation urn, you should concentrate on the volume of the remaining ashes rather than their weight. You can measure volume by using the metrics of Cubic Inches or Litres.

To learn more about the ashes capacity of a specific Urn, we provide specifications on every product page below our descriptions to guide you through this process.

Below you will find Ash Volume Tables for adults, children, babies and pets.

The average amount of ash which will remain after the cremation of an adult is between 183 to 213 Cubic Inches, which is about 3 to 3.5 Litres. Our adult urns have the capacity of between 3.0 and 5.1 Litres.
