Urn size calculator

Urns are sized in cubic inches. A widely used rule of thumb is about 1 cubic inch of capacity for each pound of healthy body weight. Many families round up to the next standard size.

This is an estimate. The volume of cremated remains varies with height, bone density, and the cremation process. Confirm with your funeral home or crematory before buying. Cemeteries and columbarium niches may have their own size limits.

Good to know

• You can buy an urn from any seller. The FTC notes that families can supply their own casket or urn.
• If the urn will go in a niche, get the niche's interior dimensions first.
• In Florida, dividing cremated remains among family members requires the consent of the person who authorized the cremation. See our cremation guide.
