What Size Urn Do I Need?
Yatskia UrnsTable of contents
1 pound ≈ 1 cubic inch
If someone weighed 150 pounds, look for an urn around 150 cubic inches or slightly larger.
Urn size refers to capacity, not just height or width. Capacity is measured in cubic inches and tells you how much cremated remains the urn can hold.
For many adults, a standard adult urn between 180 and 220 cubic inches is usually a practical option. If you are unsure, choosing slightly more capacity can help avoid sizing problems.
Once you understand this basic rule, choosing urns for ashes becomes much easier.
