How to identify the different type of film negatives


Scanning and restoring old photos and negatives can be a great personal or family project. I spent a lot of time on my family tree and meant scanning in loads of old photos. This can be time consuming but also tricky in identifying what types of film you own. I’ve put together this guide to help you figure out what you have.

135 Film - 35mm Film

This is arguably the most popular of all film negatives and easily recognised but the large number of perforations on the top and bottom. It was introduced by Kodak in 1934 and still widely used today.


126 ‘Instamatic’ Film

Introduced by Kodak in 1963, this cartridge was used mainly with low-end point-and-shoot cameras. The number 126 was intended to show that the images were 26mmx26mm square. These were very popular when released but have been discontinued since 2008. This film is identifiable by a square format with a single perforation. The film is also pre-exposed with numbers intended to make printing and viewing easier.


110 ‘Instamatic’ Film

These are easily identifiable as they’re long skinny strips of film with a single perforation. Introduced by Kodak in 1972, they’re a cartridge-based film format meant to be a miniaturised version of the 126 film.


120 Medium Format Film

This film type allows for a number of different frame sizes depending on the camera. I personally have a number of medium format negatives that measure 6x6cm and 6x9cm.


Large Format Film

Large format would refer to any image format of 4×5 inches (102×127 mm) or larger.
