35mm vs. 120 Film: Which Format Is Right for You?

Ask two film photographers which format they shoot and you will often get a strong opinion, not just a preference. 35mm and 120 film produce genuinely different results, cost differently to shoot, and suit different kinds of photography. Neither one is objectively better. The right choice depends on what you are actually trying to capture.

35mm: the versatile standard

35mm is the format most people picture when they think of film photography, and for good reason. It is the most widely produced, most widely available, and most affordable film format on the market, with an enormous range of stocks, speeds, and price points to choose from.

A standard 35mm roll typically gives you 24 or 36 exposures, which makes it well suited to the kind of shooting where you want a lot of frames without constantly reloading, travel, street photography, everyday candid shots, or anything fast moving where you are reacting to the moment rather than carefully setting up each shot.

35mm cameras also tend to be smaller, lighter, and easier to carry all day than their medium format counterparts, which matters more than people expect once you have been walking around a city for six hours with a camera around your neck.

120: bigger negatives, different look

120 film, often called medium format, uses a roll of film without the individual frame sprockets of 35mm, and the negatives themselves are dramatically larger. That size difference is the entire reason people shoot 120: more surface area on the negative means more resolved detail, smoother tonal gradation, and a level of quality that becomes especially noticeable in larger prints or heavily cropped images.

Unlike 35mm, which has one standard frame size, 120 cameras shoot in a few different aspect ratios depending on the camera body: 6x4.5, 6x6, 6x7, and 6x8 are the common formats, and each one changes how many exposures you get per roll along with the shape of your final image. A square 6x6 format and a rectangular 6x7 format feel like genuinely different creative tools, even though both come from the same roll of film.

This level of detail makes 120 a favorite for portrait and landscape photographers specifically, where fine detail, smooth tonal rendering, and large print quality matter more than shooting quickly or carrying light gear.

The tradeoffs are real, though. 120 cameras are generally larger, heavier, and slower to operate than 35mm bodies. You get far fewer exposures per roll, often somewhere between 8 and 16 depending on the format your camera shoots, which means more frequent reloading and more deliberate shooting overall. Medium format film and cameras also tend to cost more than their 35mm equivalents, which is worth factoring in if you are shooting frequently.

Choosing based on what you are actually shooting

A few quick ways to think about it:

• Travel, street, everyday shooting, fast moving subjects: 35mm's portability, exposure count, and lower cost per roll make it the practical choice
• Portraits, landscapes, anything destined for a large print or heavy crop: 120's larger negative and finer detail make the extra size and cost worth it
• Just starting out: 35mm is generally the easier and more forgiving format to learn on, both in terms of camera cost and film cost while you are still making mistakes
• Already comfortable with exposure and composition and chasing a specific look: 120 rewards that experience with a noticeably different quality ceiling

Plenty of photographers end up shooting both, reaching for 35mm when they want to move quickly and shoot a lot, and switching to 120 when a specific subject calls for the extra detail and a more deliberate pace.

What this means once your film reaches us

We process and scan both formats, 35mm and 120, in color and black and white. Print sizes are matched to your format automatically: 35mm prints at 4x6, while 120 prints correspond to your specific aspect ratio, 6x4.5, 6x6, 6x7, or 6x8, so your prints reflect the actual shape of the negative rather than being cropped to fit a standard size.

Whichever format fits the shot you are picturing, load the roll, shoot it the way the format is best suited for, and send it our way when you are done.
