According to the Cremation Association of North America (CANA), an adult cremation urn for ashes should be 200 cubic inches.

*This, of course, can vary somewhat depending on the person's height, bone density, and other factors.

Cremation urn capacity is measured in cubic inches. A cubic inch is 1" long, 1" wide, and 1" deep. Most standard adult urns have an interior capacity of about 200 cubic inches, or while "companion urns" (for two people) have a capacity of 400 cubic inches.A 200 cubic inch cremation urn is which is the industry standard size for an adult urn. It will fit the remains for almost all adults.

Of course there can be exceptions (atypical bone density, a large framed body, inconsistent results from the cremation machine, pins or other implants from surgeries, normal differences in the human body and/or cremation process). But in most circumstances the general rule of thumb works just fine.

The typical rule of thumb is that one pound of body weight equals one cubic inch of cremated remains. This is the method used in our urn size calculator above.

As a formula, this looks like:

1 lbs body weight = 1 cubic inch of remains

175 lbs individual = 175 cubic inch urn needed

Again, this varies and is no guarantee. But generally speaking, the calculation works well because the amount of remains is most often a little less than the individual's body weight.

*Please note that these sizes and ranges are approximate. 

The only way to 100% guarantee the amount of ashes is to physically measure them.
