The number of jurors on a jury typically varies depending on the type of case and the jurisdiction. For a federal civil jury in the United States, the jury must begin with at least 6 and no more than 12 members, and the verdict must be returned by at least 6 jurors, usually unanimously unless the parties agree otherwise. In criminal cases and many other jurisdictions, the standard jury size is commonly 12 jurors. Some places, like Scotland, use 15 jurors for criminal trials. Civil juries can sometimes be smaller, often 6 to 12 members, with 8 being a common size in many civil cases today. Here is a summary of typical jury sizes:

• Federal civil jury (U.S.): 6 to 12 jurors, verdict usually unanimous with at least 6 jurors.

• Criminal jury (traditional): usually 12 jurors.

• Scottish criminal jury: 15 jurors.

• Civil juries in practice today often have 6 to 8 members, sometimes up to 12.

• State and local courts may vary: for example, in Texas, district courts use 12 jurors, while some other courts use 6 jurors.

Thus, the number of jurors on a jury is generally between 6 and 12, with 12 being the classic standard for criminal juries, but can vary by case type and jurisdiction.
