What Is 135 Film Called?

You’ve probably heard the term 35 mm film, especially if you’ve ever dabbled in analog photography. But did you know it’s also called 135 film? That’s right—both names refer to the same widely used format that powered generations of photographers, from casual snapshooters to legendary artists.

The “35 mm” refers to the actual width of the film strip, a standard that traces back to early motion picture cameras. But in still photography, it's the cartridge—the little metal canister you load into your camera—that defines the 135 format. Inside, the 35 mm film is neatly wound and protected from light, making it convenient and reliable for both amateurs and pros.

This format became the backbone of film photography throughout the 20th century. Its popularity wasn’t accidental. The 135 cartridge standardized the way film was loaded and advanced, allowing compact cameras to deliver consistent, high-quality images. Whether you were shooting snapshots on vacation or chasing the perfect street scene, chances are you were using 135 film without even knowing the name.

Even today, with the resurgence of film photography, 135 remains the most accessible and widely available type. You’ll find it in everything from vintage point-and-shoots to modern SLRs. Its enduring appeal lies in its balance of portability, image quality, and ease of use.

So next time someone mentions 135 film, just think: it’s the classic 35 mm—the little cartridge that shaped how we see the world, one frame at a time.
