Tattoo conventions range from small events sponsored by a local business that may last a day, to major international conventions spanning a weekend or the better part of a week.

They may include contests and exhibitions, booths selling tattoo-related items and even booths rented for use by tattoo artists who work during the convention. Collectors may attend conventions specifically to obtain a tattoo from a particular visiting artist.

Other events may include professional events such as workshops and meetings as well as social events.

Contests, usually restricted to registered participants, usually feature a variety of categories: black-and-gray, tribal, oriental, backpiece, women, men, and so on. Judging may be by vote or by a panel of judges.
