What size urn should I buy?

Urns are sold by size, measured by the amount of ashes that each urn holds in cubic inches.
One pound of human weight will yield a little less than 1 cubic inch of remains.
According to the Cremation Association of North America (CANA) the standard capacity of a single adult urn should be 200 cubic inches.
The size of each urn in cubic inches is listed with the item’s description.
