Cremation Urn Size Info


Cremated remains (ashes) can vary in amount due to different cremation processes, temperature variations, bone structure of the deceased, height and age. Weight does not effect the size of the urn required as fat is a combustible element of nature and naturally disappears.

A 200 cubic inch urn is, in 98% of cases, more than large enough to hold the ashes of an adult. If unsure please contact your crematorium or funeral director to confirm exactly what size urn you need to purchase. 

The ashes of very tall adults would be best suited to an urn that is 220 cubic inches/ 3.6Lt  or larger.

As calculating ash amount is not an exact science, the following is a guide only. We do not guarantee the following calculations will be true 100% of the time.

What size urn will we need?

Tall adults- 6" /182.88cm and over will need a 220 cubic inch cremation urn

Average height adult- 5"/ 5.9"  will need a 200 cubic inch urn

One month old baby to three year old- needs an urn of approximately 40 cubic inches/ 0.65 litres

Pre term babies- please ask your funeral director for more specific adivice on ash quantity.

What if the ashes do not fit in the urn?

If the amount of cremated remains cannot fit inside the selected urn, then any excess cremated remains is be returned to the family in a temporary urn supplied by the crematory or funeral home.

Premium Urns provides the information on this page as a guide only. Premium Urns shall not be held responsible for any situation where all the ashes do not fit in the urn.
