How Deep Are Graves? The Six-Feet Myth Explained

"Six feet under" is a famous phrase, but most modern graves aren't six feet deep. Depth depends on local regulations, the cemetery, the soil and whether the grave holds one or two burials.

Where "six feet" comes from

The six-foot depth is often linked to plague-era rules in 17th-century England, intended to limit the spread of disease. It became a common rule of thumb, but modern regulations rarely require exactly six feet.

Typical depths today

• Single graves are commonly about 4 to 6 feet deep.
• Regulations in many places focus on the amount of soil over the casket or vault — often at least 18 inches to 2 feet.
• Double-depth graves are dug deeper — often 7 to 8 feet — so two caskets can be stacked. See double-depth burial.
• Cremation burials are much shallower, often 2 to 3 feet.

Rules vary by province, state and cemetery.

Why depth matters for headstones

The headstone sits on a foundation at the head of the grave. A properly supported grave — with a liner or vault — keeps the ground stable. Shallow, unsupported graves are more likely to settle and tilt the stone.

Who decides the depth?

The cemetery digs the grave according to local law and its own rules. Families rarely need to specify depth, except when buying a double-depth plot for a couple. Ask the cemetery office if you're planning ahead.

Key Takeaways

• Most graves are about 4–6 feet deep, not always six.
• Rules usually set a minimum amount of soil over the casket.
• Double-depth graves are deeper to hold two burials.
• Cremation graves are much shallower.
