What size urn fits into a niche?

One standard size measures about 9 inches cubed, but most cemeteries offer several sizes for individuals, families, or couples. There may also be larger, fancier, and more pricey niches and smaller, simpler, and more budget-friendly niches in the same columbarium. It is all dependent on the columbarium you're interested in.

The standard niche size for cremation urns is between 9 and 12 inches cubed. The average size of a cremation urn is 9 to 13 inches for a vase type and 10 to 12 inches for a rectangular box type. It would be best to contact the columbarium to find out the exact niche size so you can choose the best cremation urn size.
