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 affect the size of the urn required as fat is a combustible element of nature and naturally disappears.

A 200 cubic inch / 3.1Lt 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?
