How deep graves are dug at a burial site will depend on local practice and where you live, despite the expression of “6 feet under” as a common euphemism for death. It is based on the idea that the standard depth of a grave is 6 feet, but some graves in a cemetery may be 2 feet or 4 feet deep.
Still, there are a lot of theories and explanations about the belief that graves are always 6 feet deep. Some of the ideas about how 6 feet became a norm for burials are more plausible than others.This article will discuss the possible origins of the “6 feet under” belief. It also discusses cultural practices and legal regulations for modern burial.

How Deep Are Graves?
There is no nationwide rule that says graves must be 6 feet deep. Regulations on how deep graves are can vary from state to state and city to city. For the most part, graves dug today are not 6 feet deep.
The state of New York, for example, lacks a statewide grave-depth rule. New York City, though, requires at least 3 feet between the ground surface and the top of a casket or coffin. If the body is in a concrete vault, it needs to be just 2 feet below ground.
For single gravesites, roughly 4 feet deep is closer to the norm. The International Cemetery, Cremation & Funeral Association calls for grave widths of 2.5 feet (30 inches) and lengths of 8 feet, along with their best practices for how cemeteries should lay out graves.
In neighboring Pennsylvania, the top of a vault or grave liner has to be at least 1.5 feet below ground. When there is no vault or grave liner, there must be 2 feet between the top of the casket and the surface.
An exception is double- or even triple-depth plots. In these plots, caskets are “stacked” vertically in the same gravesite. A single grave in one of these plots might be 7 to 12 feet deep.
Can You Be Buried on Your Own Property?Technically, there are only three U.S. states that bar home burial: California, Indiana, and Washington. A few other states will only allow home burial if a funeral director is involved. The majority of states have no law forbidding home burial, but speak with your local authorities (including the health department and local funeral commission) to ensure you follow state laws governing all burials.

Where Did “6 Feet Under” Come From?
The idea that graves should always be 6 feet deep has been around for a long time. There is no agreement about where this idea came from. Here are a few theories about why people may have decided to bury their dead 6 feet deep.
The London Plague of 1665
In 1665, London officials issued a pamphlet they hoped would help stop an outbreak of the plague orBlack Death. Some people think this was the origin of the 6-foot standard.
The Lord Mayor of London ordered that all “graves shall be at least 6-foot deep” under the presumption that doing so would prevent the spread of disease.Unfortunately, the pamphlet didn’t explain the reason for the 6-foot mandate.
There are a few reasons why this probably isn’t the origin of the 6-foot standard.
Between 1665 and 1666, there were an estimated 100,000 plague victims. Many were buried in mass graves called “plague pits.” These graves were sometimes 20 feet deep or more.
The orders also didn’t say in force long. This is because the outbreak quieted in 1666 after the Great London Fire. It’s not likely, then, that the “6-foot requirement” had enough time to become a tradition.
While it’s possible that London’s 1665 plague orders created the lasting impression that graves are always 6 feet deep, it’s not likely.
Gravedigger Safety
Some people think 6 feet was just a matter of safety. Deeper graves might need bracing to prevent cave-ins. This would be especially true if the soil was sandy.
Average Gravedigger Height
The depth could have also made grave digging easier. At 6 feet, an average-sized gravedigger could still toss dirt out with a shovel. He could also get in and out without a ladder.
To Prevent Disturbing the Corpse
Grave robbery or “body snatching” was a serious problem during the early 1800s. This was especially true in England and Scotland.
Cemeteries had a lot of ways to deter grave robbers, including:
People may have also buried bodies 6 feet deep to help prevent theft.
There was also concern that animals might disturb graves. Burying a body 6 feet deep may have been a way to stop animals from smelling the decomposing bodies.
A body buried 6 feet deep would also be safe from accidental disturbances like plowing.
To Prevent the Spread of Disease
People have not always understood how diseases spread. During disease outbreaks, they may have feared that bodies could transmit disease.
While it is true that some illnesses likecholeraandtuberculosiscan infect people who handle bodies, this is not true for other diseases like bubonic plague.
Still, this may be one of the reasons why people thought bodies should be buried 6 feet deep.
Folklore/Rule of Thumb
An old “rule of thumb” says graves should be as deep as the deceased is long. This rule of thumb has unknown origins.
In the 17th and 18th centuries, the average male was 5.48 feet tall. It’s possible, then, that 6 feet was just a good rule of thumb.
Summary
It’s not clear where the “6 feet under” idea came from. It might have been for the safety of the gravedigger, or to make grave digging easier. People may have also believed it would keep bodies from being disturbed or prevent the spread of disease.
In the United States, there are no nationwide rules outlining how deep graves should be. States usually have their own rules. Generally speaking, most graves dug today are only about 4 feet deep.
