How many people usually serve on a petit jury?

Traditionally, a petit jury consists of 12 members, though there is no longer a uniform requirement for this number.12

In many jurisdictions, modifications have been made to this standard:

• Minor criminal cases: Some jurisdictions allow for a jury of six members.1
• Civil cases: Federal courts in the United States typically employ a six-person jury.1

While the 12-member jury has deep historical roots in English law and American law, the specific number of jurors and the requirements for a valid verdict vary significantly depending on the jurisdiction and the nature of the case. If a jury cannot reach the required agreement, the judge may declare a mistrial.12
