In short: these are just different types of photographic film that differ in frame size, and accordingly in image quality and compatible cameras.
135 (35mm) – classic
Most likely, your family albums were shot on this film.
- One roll of film usually gives 24 or 36 frames; there are also movie film rolls of this format where the number of frames can vary.
- Frames are rectangular, sized 24×36 mm.
- The most beginner-friendly format.
- Compatible with point-and-shoot cameras, as well as more professional automatic or mechanical cameras.
120 – medium format
- Used with medium format cameras (Bronica, Pentax 67, and others), they are quite bulky, so definitely not a pocket story.
- The number of frames depends on the camera itself: usually 12, generally from 8 to 16.
- Frame size can vary: 6×4.5, 6×6, 6×7, or even 6×9 cm.
- Photos come out detailed because 120 film is larger than 135 and allows for higher quality images.
110 – small retro format
- Today it’s rare, but it still has its fans.
- The frames are very small: 13×17 mm.
- The image quality is lower than 135 or 120, but that’s the point – they look more vintage.
Today, this film is made only by Lomography.
Which format to choose?
- Want to just get started? Get film 135 – it’s accessible and easy.

But first, make sure you have the right camera, because each one can read only one specific film format.
