Cremation Urns
for your pets or other loved ones
All urns are high-fired stoneware
There is a standard for adult urns. We tend to follow the guidelines set by the Cremation Association for North America (CANA). Their standard for an adult urn is 200 cubic inches. In many cases, this can be off by 10-20% in either direction depending on many factors. The industry standard for rough estimates is 1 cubic inch of cremains for every 1 pound of healthy body weight. This industry standard should only be used as an approximate size required.
There is no real standard for pet urns. But, because of the variations in cremation processing for pets we generally advise 1.5 pounds = 1 cubic inch, especially for smaller pets.
If you have the ashes you can measure the bag by making it into a square and multiplying the length x width x height. That will give you the cubic inches. For instance a box that is 4"L x 4"W x 5" H = 80 cubic inches.
