Letterboxing is an outdoor hobby that combines elements of orienteering, art, and puzzle solving.

Letterboxing is used as an alternative to a full-screen, pan-and-scan transfer of a widescreen film image to videotape or videodisc.

Letterboxing was developed for use in 4: 3 television displays before widescreen television screens were available, but it is also necessary to represent on a 16: 9 widescreen display the unaltered original composition of a film with a wider aspect ratio, such as Panavision's 2. 35: 1 ratio.

Letterboxing is another treasure hunt game.
