Just like people and pets, urns come in many different shapes and sizes. Please Note: When we refer to "healthy" weight, we mean a weight prior to any illness that may have resulted in weight loss, if applicable.
Follow these rules to better determine the size of the urn you need:
- In order to hold all your loved one's ashes you'll need to know what the approximate healthy body weight of the person or pet you are shopping for.
- One pound of healthy body weight will yield just less than 1 cubic inch of ash.
Assume for shopping purposes that: 1 pound healthy body weight = 1 cubic inch ash.
- Cremation urn item descriptions list the size of an urn in Cubic Inches. If you know the healthy weight of the deceased - then you know the size of the urn you need. Approximate Weight = Approximate Cubic Inch Size.
- Easy example: A cremated 100 pound person (healthy weight) will yield almost 100 cubic inches of ashes. So, if 1 pound = 1 cubic inch then this person would need an urn that is approximately 90-100 cubic inches or larger.
Urn Sizing Notes
- There are a lot of other factors that play into how much cremains you will actually receive from the crematorium. Because of that we can't guarantee 100% of the time that an urn will be large enough but if you follow our rules above, or call us to discuss - 99.95% of the time we'll be right on.
- The 1 to 1 ratio of weight to cubic Inches will insure you purchase an urn that is the right size 99.95% of the time.
- Urn capacity can only be too small. You can use any size urn that holds more than you need.
- Cremated remains (ashes) can vary in amount due to different cremation processes, temperature variations and the bone structure of the decedent. Buy an urn at least slightly larger than calculated to avoid having the urn be too small for the ashes.
- The Cremation Association of North America (CANA) determined that the standard capacity of a single adult urn should be 200 cubic inches. Keepsake urns, Keepsake Jewelry, Small and Medium Size Urns are exceptions.
