If a person weighs 120 lbs, what size urn is needed?

When selecting an urn for cremated remains, a common guideline is that you need approximately one cubic inch of urn capacity for each pound of body weight. In this case, since the person weighs 120 lbs, an urn with a capacity of 120 cubic inches is appropriate. This size will allow for the complete collection of the cremains, ensuring they fit comfortably without being overcrowded.

Choosing a larger urn may not be necessary unless there are specific personal preferences or needs, such as including keepsakes or additional items along with the ashes. An urn that is too small would not accommodate all of the ashes, which is why the 120 cubic inch urn is the right fit for a person weighing 120 lbs.
