Urn Size Calculator

How do I calculate the right size of an urn I need?

Just like people and pets, urns come in many different shapes and sizes. The general rule of thumb is for every pound of the person's total weight you will need one cubic inch of space. So if a person weighed 150 lbs. you will need an urn that is 150 cubic inches or larger.
