How Many Urns Fit in One Grave?

Families often ask whether Grandma's ashes can go in Grandpa's grave, or how many family members can share one cremation plot. The answer depends on the cemetery, but there are some common patterns.

In a full casket grave

Many cemeteries allow one casket plus one or two urns in a standard grave, and some allow more. The urns are usually placed above the casket. Others count every interment separately and set a strict limit. See burying ashes in an existing family grave.

In a cremation plot

Cremation-only plots are smaller, often around two by two feet to four by four feet. Many hold two to four urns, depending on size and the cemetery's rules. See cremation plot headstone size.

Urn vaults

Some cemeteries require each urn to go inside an urn vault (a small concrete or polymer box) so the ground doesn't sink. Vaults take up more room than the urn alone, which affects how many fit.

Fees and records

Each urn burial usually means its own interment (opening and closing) fee and a record in the cemetery's register. The plot owner, or their heirs, normally has to authorise each burial. See who owns a headstone and how to transfer cemetery plot ownership.

Names on the headstone

Plan the headstone for everyone who might share the grave. You can leave space now and add names later, or add a small plaque or flat marker. See adding a name and date to an existing headstone and listing children's names.
