Urn Size Calculator
Choosing the right urn shouldn't be guesswork. Estimate the volume of cremated remains from a few simple details — and we'll recommend the urn size that fits, then point you to the right collection.
Cremation ash volume
— cups
Estimates use the established ~1 cu in per lb of healthy body weight, refined for frame, age and gender. Always confirm with your funeral director.
A closer estimate than the rule of thumb
The common guideline is one cubic inch of ashes per pound of healthy body weight. Our calculator starts there, then refines for body frame, age and gender so you choose an urn that truly fits.

Find your frame size in seconds
A person's body frame — small, medium or large — affects bone mass and therefore the volume of ashes. Two simple ways to estimate it:
Quick wrist test
Wrap your thumb and index finger around the other wrist:
- Overlap → small frame
- Just touch → medium frame
- Don't meet → large frame
Precise method
Measure the wrist circumference with a flexible tape, then use the chart.
| Frame | Wrist (men) | Wrist (women) |
|---|---|---|
| Small | 5.5″ – 6.5″ | under 5.5″ |
| Medium | 6.5″ – 7.5″ | 5.5″ – 6.25″ |
| Large | over 7.5″ | over 6.25″ |
General guidance for adults; taller individuals trend one frame larger.
