There is no standard size. A typical plot in the US is 30 inches wide (80 cm), 7 feet long (210 cm) and 6 feet deep (180 cm). Florida requires new plots to be 42 inches wide (105 cm), 96 inches long (240 cm), with 12 inches of soil over the top of the burial container (30 cm). Jewish tradition requires the grave to be at least 40 inches deep (100 cm), and wide and long enough for the body plus coffin, if one is used. Obviously, cemeteries that routinely use concrete burial vaults to enclose the coffin will require larger plots than those where the dead are buried in just a wooden coffin. Burial of cremated remains permits use of much smaller plots.
