Film: 24mm Vs. 35mm

film, not as popular but still used

Two types of film, 24mm and 35mm, are the most common non-digital film media.

What is 24mm Film?

24mm film cartridges

Advanced Photo Systems, or APS, use 24mm film rolls. 24mm stands for the width of the strip of film from edge to edge (the actual frame size is only 16.7mm x 30.2mm). It is usually only available by order on the Internet, as most people no longer use this type of film or cameras.

24mm Picture Formats

24mm film uses three formats to capture pictures. The High Definition format provides pictures with an aspect ratio of 16:9 and are developed into 4---7 prints. The Classic format provides pictures with an aspect ratio of 3:2 and are developed into 4---6 prints. The Panoramic formats provides pictures with an aspect ratio of 3:1 and are developed into 4---11 prints.

What is 35mm Film?

35mm film cartridge

35mm film, named for the width of the strip from edge to edge, is the non-digital choice of most photographers for still photography and motion pictures. This film has not really changed since it was introduced by William Dickson and Thomas Edison in 1892, and you can still buy it in stores.

35mm Picture Formats

Classic 35mm Camera

35mm film can produce pictures in various sizes. The most commonly used formats are 8x10, 5x7, 4x6, and 3x5. Pictures can be developed multiple times and in multiple sizes from one roll of film. This makes it more popular with photographers.

Impact of 35mm Film

Digital Camera

Of the two film sizes, 35mm film is more popular. In fact, digital cameras base the frame size of their single reflex lenses on the 35mm camera.

Main Differences

There are no real differences between 24mm and 35mm film except for the width of the film strip and the casing.
