A roll of 120 film does not have one fixed number of photographs. The answer depends on the image format your camera exposes.
For the common medium-format sizes, expect roughly:
| Format | Typical photographs on a 120 roll |
|---|---|
| 6×4.5 / 645 | 15–16 |
| 6×6 | 12 |
| 6×7 | 10 |
| 6×9 | 8 |
Those figures are useful starting points, not promises. The manual for the exact camera, film holder or magazine is always the final authority.
The word "120" names a roll-film format. It does not mean 120 photographs, and it does not mean the film is 120 mm wide. The camera chooses how far to advance the roll between exposures, so the same 120 film can produce very different counts in different cameras.
For the broader difference between 35mm and roll film, read 35mm vs 120 Film. For the different frame shapes themselves, see What Is a Medium-Format Camera?.
If you are choosing among those frame shapes rather than simply counting a loaded roll, see 6×4.5 vs 6×6 vs 6×7 vs 6×9: Medium Format Sizes Compared.
| Camera format | Usual 120 count | Manual-backed example |
|---|---|---|
| 6×4.5 / 645 | 15–16 | Pentax 645: 15 |
| 6×6 | 12 | Hasselblad A12: 12 |
| 6×7 | 10 | Fujifilm GW670III: 10 |
| 6×9 | 8 | Fujifilm GW690III / GSW690III: 8 |
A useful way to read the table is: the larger the frame, the fewer frames fit on the roll.
The Pentax 645 manual specifies its 120 holder as 15 frames per roll. Hasselblad’s official 500 Classic-era manual specifies the A12 magazine as 12 exposures on 120-type film. Fujifilm’s GW670III/GW690III/GSW690III manual specifies 10 exposures for 6×7 and 8 for 6×9 on 120.
These documented examples explain why "120 gives 16 shots" is too broad. Sixteen is common for some 645 cameras, but it is not a universal 645 count, and it is not relevant to a 6×6, 6×7 or 6×9 camera.
All of the formats above use the same basic width of 120 roll film. The difference is the length of film consumed by one frame.
A 6×4.5 camera exposes a shorter frame and moves the film forward by a relatively short distance. A 6×9 camera exposes a much longer frame and needs more film between one picture and the next. The roll therefore ends sooner.
The final count is determined by several camera-specific factors:
That is why it is better to ask, "How many exposures does this camera make on 120?" rather than, "How many photos are on 120 film?"
645 gives the highest count among the common medium-format sizes in this guide. Most 645 cameras make either 15 or 16 exposures from a full 120 roll.
Both values are normal. The Pentax 645’s dedicated 120 holder is a 15-frame design, while other 645 cameras use spacing that allows 16. A counter that stops at 15 is not necessarily malfunctioning, and you should never force the advance in the hope of creating an extra frame.
The relatively generous count is one reason 645 works well for travel, portraits, events and everyday photography. You still get a substantially larger image than 35mm, but you have enough frames to make variations when a scene changes.
Do not assume every camera called "645" behaves identically. Some systems have interchangeable film inserts, different film backs or motorised winding mechanisms. Check the exact model and back, especially if buying used equipment with parts from more than one generation.
A square 6×6 camera generally gives 12 exposures on a 120 roll. This is the classic count for many TLRs, box cameras, folders and modular 6×6 SLR systems.
Hasselblad’s A12 magazine makes the number explicit in its name and specification: it is a 12-exposure 120-film magazine. Other 6×6 cameras may use a red window in the rear door, while more advanced systems use automatic counters, but the usual full-roll count remains twelve.
Twelve frames creates a different rhythm from 645. There is room for a short portrait sequence or a walk through a neighbourhood, but less room for repeated experiments. That is part of the appeal for many photographers: each frame tends to receive a little more attention.
Remember that square format does not mean you must publish square photographs. You can crop later, but the counter still gives you twelve square negatives, not twelve rectangular 6×7 frames.
A 6×7 camera usually gives 10 photographs on a roll of 120. The Fujifilm GW670III manual lists 10 exposures for 6×7 on 120; 6×7 Mamiya RB67 backs are also normally ten-frame designs.
Ten exposures can sound limiting if you are used to 36-exposure 35mm film, but it can be a productive constraint. It rewards checking focus, exposure, framing and subject position before each release.
The count is also useful for planning. A single roll can cover a compact portrait session, a carefully selected sequence of landscapes, or a small editorial assignment. If you need several lighting setups or many variants of a subject, bring additional rolls rather than trying to stretch the counter past its intended stop.
A 6×9 camera usually gives eight exposures on a roll of 120. Fujifilm’s GW690III and GSW690III manual specifies exactly that count for their 6×9 format.
With only eight frames, the format naturally encourages an economical approach. It suits photographers who prefer a wide 3:2-like rectangle and who want a large negative for a limited sequence of landscapes, architecture, travel scenes or portraits.
Eight is a typical count for a full 120 roll in this format, not a general rule for every camera with a large image. Panoramic roll-film cameras can make even fewer photographs because their frames are wider still.
120 and 220 are related roll-film formats, but they must not be treated as automatically interchangeable.
Fujifilm’s Professional Film Data Guide describes the same approximate 61.5 mm film width and the same image-size categories for 120 and 220. The practical difference is roll length and backing paper. A 120 roll has backing paper along its length; 220 uses a longer film length and does not have backing paper behind the full length of the film.
In a camera designed for 220, that longer roll often produces roughly double the 120 count. For example, the Fujifilm GW670III/GW690III/GSW690III manual lists:
| Format | 120 | 220 |
|---|---|---|
| 6×7 | 10 | 20 |
| 6×9 | 8 | 16 |
But this only applies when the camera or film back is specifically made for 220 and correctly configured. The Fujifilm manual requires the correct 120/220 film-selector and pressure-plate settings. Using the wrong setting can place the film incorrectly at the focal plane.
Do not assume that a 220 roll is safe simply because it can be inserted into the camera. Follow the manual for the exact body and back.
Use this short check before every unfamiliar camera or newly acquired film back:
Cameras with automatic counters usually require the backing paper’s start arrow to be aligned with a mark in the film chamber. If the film is loaded past or before that mark, the counter may be inaccurate and the first or final frame can be affected.
On red-window cameras, use the frame number sequence intended for that camera and format. Do not simply advance to a number that looks familiar: backing paper can carry different numbering sequences for different frame sizes.
At the end of the roll, make the final exposure indicated by the counter, then wind the film fully onto the take-up spool before opening the back. Opening a camera before the film is secured risks fogging the remaining roll.
Knowing the count helps you decide how to work before you leave home.
A 645 roll allows more alternate expressions, small exposure changes or repetitions of moving subjects. Twelve 6×6 frames suit a short, coherent project. Ten 6×7 frames invite more deliberate decisions. Eight 6×9 frames can be treated almost like a compact contact sheet of final selections.
That is not a rule about seriousness or skill. It is simply a difference in pacing. The best approach is to load the format whose frame count and image shape match the kind of session you intend to make.
If you are choosing a first system rather than just counting a loaded roll, Best Medium Format Cameras for Beginners compares practical 645, 6×6 and 6×7 options. The Camera_DATA catalogue can then help you compare exact camera types and specifications.
No. "120" is the name of a roll-film format. It is neither an exposure count nor the width of the film in millimetres.
Yes, if each camera accepts 120 film. The same type of film will make about 10 pictures in the 6×7 camera and about 8 in the 6×9 camera because the cameras expose different frame sizes.
It may be working exactly as designed. Some 645 cameras, including the Pentax 645 with its standard 120 holder, are 15-frame cameras. Check the manual before assuming there is a fault.
Do not force the advance. The camera’s spacing and end-of-roll mechanism were designed to protect the film and maintain frame separation. Forcing it can overlap frames, tear film or create an unexposed final area.
Only follow this if the manufacturer’s manual specifically permits it and explains the procedure. The correct film setting, pressure plate and winding behaviour matter. Physical fit alone is not enough.
Incorrect loading, a premature advance problem, an unusual format, or a camera/back configured for a different film length can all affect the result. Keep the developed film and inspect the frame spacing before drawing a conclusion.
