Finding the right urn for a loved one is a very personal decision, and we know it can feel heavy. Our goal is to make this part simple, clear, and as stress-free as possible.
Even though urn capacity can sound technical, it’s actually very straightforward once you know one basic rule.
The Simple Rule (Used by Professionals)
The guideline most funeral professionals follow is:
1 pound of body weight (before cremation) = 1 cubic inch of urn capacity
For example:
-
If your loved one weighed 180 lbs, you’ll need at least 180 cubic inches
-
If they weighed 220 lbs, you’ll need at least 220 cubic inches
Because exact weights aren’t always known, our standard adult urns are made with a 250 cubic inch capacity, which comfortably fits the vast majority of individuals.
Common Urn Sizes Explained
250 Cubic Inches — Individual Urn
This is the most common choice. It’s suitable for most adults up to approximately 240 lbs and works well for single-person memorials.
500 Cubic Inches — Companion Urn
Designed for:
-
Couples who wish to be placed together
-
Families who want extra space
-
Situations where personal mementos may be included
About physical size:
A 500 cubic inch urn does not look twice as big. In most cases, it’s only about 4 inches taller and 2 inches wider than a standard urn. Exact measurements are always listed in the product images.
A Few Helpful Considerations
If you plan to share the ashes
If remains will be divided into keepsake urns or memorial jewelry, you may not need one large urn. However, if you’re starting with a main urn, it should still meet the full capacity needed using the 1-to-1 rule.
Can an urn be too big?
No. An urn does not need to be filled completely to be respectful. Extra space does not affect preservation or appearance. If you’re deciding between two sizes, choosing the larger one is always the safer option.
