To calculate the Urn size you require is, for every pound of body weight, allow one cubic inch of cremated remains. If you are measuring in Kilograms, the conversion is 1 Kilogram = 2.2 Pounds.
It is important to note that if the deceased was taller, you may need to add extra capacity and for stillborn/young babies you will also need to add slightly more for the capacity. Fat is burnt away during the cremation process, so will have less of a bearing on the final amount of ashes which you will need to also consider when choosing the right urn size.
