How Many Cubic Inches?
The amount of ashes, or “cremains”, that each urn holds is measured in cubic inches. The industry standard is approximately 1 pound of healthy weight to 1 cubic inch of cremains; that is, a 180lb person will require roughly 180 cubic inches.
Most adult cremation urns will hold 200 cubic inches at a minimum, and some hold more. We list the cubic inches that each urn will hold in the product description for each of our products.
For a larger individual, the measurements can be a little tricky. The “cremains” are composed of the bone matter that remains after the cremation process. This means that regardless of a person’s actual weight, the cremains should be around the same amount as the average person of the same height.
Here is a handy chart to help you figure weight based on height.
Of course, there are variations in bone density and structure, so for a larger individual, it is wise to err on the side of more cubic inches. Often, families will choose a companion urn, which usually hold 400 cubic inches.
Some couples choose a companion urn as a way to signify their inseparability. These urns typically will hold 400 or more cubic inches, and can often be made with or without separate compartments inside. If a divider is chosen, then both sides will be roughly 200 cubic inches. Again, be sure to see the dimensions on each product page, and use the same calculations as above to determine if the urn will be suitable.
Keepsakes urns vary widely in size; some hold as little as 1 cubic inch of cremains, while others hold up to 100 cubic inches. Choose your keepsake urn carefully depending on its inteded usage. If you would like to divide the cremains among several relatives, it is usually best to get several 50+ cubic inch keepsake urns.
