Introduction to Film Formats: It's Not Just About Size

By Paul McKay

This article is your guide through the diverse landscape of film formats available today. From the best-selling 35mm to the large format films, and many different instant films, each format offers its own set of advantages and artistic possibilities.

Here's a quick overview of size and features to get us started:

 *Width/length can be used interchangeably as it depends on the orientation of the scene on the frame. Think of them as (i) one side, and (ii) the other side, of the image!

Now, let's delve deeper into each of these film formats, exploring their unique characteristics and what makes them beloved by analogue photographers around the globe. You can learn more about the types of film available in each format in our Beginner's Guide to Film.



The Classic 35mm Film: A Versatile Choice


When it comes to film photography, the 35mm format is undeniably iconic. Its journey began in the early 20th century, initially finding its place in motion pictures. The standard 35mm film, with its 36x24 mm frame size, was actually derived from motion picture film stock. It wasn't until Leica commercialised the first 35mm camera in the 1920s that this format transitioned into the world of still photography, revolutionising the way photographers captured the world.

The beauty of 35mm film lies in its versatility and accessibility. As the most popular film format, it is compatible with a wide range of cameras, from vintage rangefinders to modern SLRs. Its popularity is partly due to its convenience - the film comes in light-tight metal canisters, holding strips of photographic film usually up to 36 exposures, and 35mm film can be developed in many film processing labs arounds the world. This format strikes a balance between image quality and ease of use, making it an excellent choice for both beginners and professionals. It's perfect for a variety of photography styles, including street, portrait, and landscape.

One of the most significant advantages of 35mm film is the availability of a wide range of film types in 35mm format. Whether it's the classic black and white, vibrant colour negatives, or the unique characteristics of slide and reversal films, 35mm offers something for every photographer's taste. Its relatively small size also allows for compact camera designs, which has been a driving factor in the enduring popularity of 35mm format cameras.

Despite the digital revolution, 35mm film has held its ground. It is celebrated for its aesthetic appeal as well as it's ease of use. In a world where immediacy is often prized, 35mm film encourages a more thoughtful and intentional approach to photography. It is a format that remains exceptionally accessible!



The Medium Format 120 Film: For the Detail Enthusiasts


The story of 120 film, often referred to as medium format film to differentiate it from 'large' format, is deeply entwined with the history of photography. Introduced by Kodak in 1901 for their Brownie No. 2 camera, it marked a significant departure from the bulky glass plate photography prevalent at the time. The 120 film, with its paper backing, made photography more accessible and portable, allowing for greater flexibility in capturing images.

Medium format 120 film is renowned for its superior image quality and resolution. Unlike the fixed 36x24mm frame of 35mm film, 120 film offers a variety of frame sizes including 6x4.5, 6x6, 6x7, and even 6x9 cm, depending on the camera used. This flexibility allows photographers to choose the aspect ratio that best suits their artistic vision, whether it’s the square format favoured in classic portraiture or the wider formats ideal for breathtaking landscapes.

Another distinctive feature of 120 film is its fine grain relative to the image size which contributes to the incredible detail and clarity of images. This quality makes it a favourite among professional photographers, especially those specialising in portrait, fashion, and landscape photography. The larger negative size not only captures more detail but also provides a shallower depth of field, allowing for stunning bokeh effects that add a dreamlike quality to photographs.

Similar to 35mm film, you can find a large choice of 120 film brands and types to get the exact look that you want for your photography.

Despite advancements in digital photography, 120 film remains a staple for those who appreciate the nuances of analogue. Its ability to capture a wider dynamic range and richer tones gives it a unique aesthetic that is difficult to replicate with digital sensors. For photographers who value the tactile process and the thoughtful approach that film photography demands, 120 film offers an enriching and rewarding experience.



Large Format Photography: 4x5 and Beyond


Large format photography, encompassing film sizes like 4x5 inches and larger, is steeped in the earliest traditions of photography. Originating in the 19th century, large format film was the standard for professional photographers, especially in studio settings and landscape photography. The size of the film, significantly larger than 35mm or medium format, allows for unparalleled detail, resolution, and tonal range.

Using a 4x5 inch film, photographers have the advantage of a vast negative area, which translates to finer detail and the ability to produce large prints without losing image quality. This format demands a methodical approach, often involving manual adjustments on large, bellows-type cameras and careful consideration of composition and exposure. It's a process that harkens back to the roots of photography, offering a pure, hands-on experience.

While large format photography can be more challenging and time-consuming than smaller film formats, the results are often extraordinary, with a level of detail and depth that is hard to replicate in other formats. The format is particularly popular for landscape, architectural, and fine art photography, where its high resolution and control over plane focus (tilt and shift movements) are invaluable.

In today's fast-paced digital world, large format film photography remains a revered practice for those seeking to connect with the historical aspects of the craft and for projects where image quality is paramount. It's a format that encourages slowing down, contemplating the scene, and immersing oneself fully in the photographic process.



The Compact and Retro 110 Film


The 110 film format, introduced in 1972 by Kodak, marked a significant step in making photography more accessible and portable. This pocket-sized film cartridge was developed during the era of "pocket cameras," reflecting a desire for more convenient and user-friendly photography options, especially for casual photographers and hobbyists.

Measuring a mere 17 x 13 mm, the 110 film's diminutive size made it a hit for on-the-go shooting. Despite its small size, the 110 film was capable of producing relatively high-quality images, making it a popular choice for everyday photography. The ease of loading the film cartridges, which eliminated the need to thread film onto a take-up spool, further added to its appeal.

The revival of interest in analogue photography has brought new life to the 110 format. Today, it is manufactured fresh by Lomography with a range of 110 films and cameras. It is celebrated for its vintage charm and the unique, nostalgic quality it brings to photos. Although the film choices and camera options for 110 are not as extensive compared to other formats like 35mm and 120, its distinct aesthetic and simplicity continue to attract a dedicated following.

For those who delight in the charm of vintage photography and enjoy the challenge of working with smaller negatives, 110 film offers a unique avenue to explore the art of film photography.



The Vintage Charm of 620 and 127 Films


Delving into the realm of vintage film formats, 620 and 127 films hold a special place in the history of photography. The 620 film, introduced by Kodak in 1931, was essentially the same as the 120 film but with a different spool. This format was created to encourage photographers to buy new cameras, as 620 spools were not compatible with 120 format cameras. Despite this, 620 film found its popularity due to its use in a variety of Kodak cameras, becoming a staple in mid-century amateur photography.

On the other hand, the 127 film format, introduced in 1912, was used in the famous Kodak Vest Pocket camera – often referred to as the "Soldier's camera" during World War I. With a frame size of 40 x 40 mm (in square format), it became popular for its portability and was widely used in smaller, simpler cameras for casual photography. The 127 film provided a bridge between the small 35mm and larger medium formats, offering a unique blend of convenience and quality.

Today, both 620 films and 127 films are cherished for their historical significance and the nostalgic touch they bring to images. While they are not as readily available as more common formats like 35mm or 120 film, they continue to be sought after by vintage camera enthusiasts and photographers looking to experience the classic feel of early 20th-century photography.

For those interested in exploring the roots of film photography or seeking a distinctive vintage aesthetic, these formats offer a journey back in time and a different perspective on the art of capturing images.

The Instax series of instant films, introduced by Fujifilm, has redefined instant photography for the modern era. The journey of Instax began in the late 1990s, rejuvenating the instant film market with its fresh approach and vibrant image quality. The Instax film comes in three primary formats: Mini, Square, and Wide, each offering a distinct photographic experience.

Instax Mini, the first in the series, quickly became popular for its credit card-sized prints, making it a favorite for casual snapshots, journaling, and sharing. The small size of the prints, measuring 62 x 46 mm, encourages creativity and spontaneity, making it perfect for capturing everyday moments.

Instax Square, as the name suggests, offers a square format (62 x 62 mm) reminiscent of classic Polaroid images. This format strikes a perfect balance between the nostalgic appeal of instant photography and modern design, allowing for more creative compositions and a wider range of uses, from artistic projects to party snaps.

Instax Wide, the largest of the three, provides a more expansive canvas with its prints measuring 99 x 62 mm. This format is ideal for capturing landscapes, group shots, and detailed close-ups, offering a broader scope for photographic expression. The larger size of Instax Wide prints makes them particularly appealing for displays and gifts.

The Instax series has not only revived the joy of instant photography but has also introduced it to a new generation of photographers. Its ease of use, fun design, and instant gratification make Instax films a delightful choice for both beginners and experienced photographers seeking a unique and playful way to capture life's moments.



Polaroid Films: 600, i-Type, and Go


Polaroid film, a name synonymous with instant photography, has a rich history that revolutionized the way we capture and share moments. The original Polaroid film, developed by Edwin Land and introduced in the late 1940s, was a groundbreaking invention that allowed photographs to develop within minutes of being taken.

The Polaroid 600 series film, introduced in the 1980s, became a cultural icon. Its distinctive square format and immediate development made it a favorite for capturing life's spontaneous moments. The 600 films are known for their classic, soft-toned images with a vintage feel, making them a nostalgic choice for many.

With the advent of the digital age, Polaroid adapted and introduced the i-Type film. This new film is similar to the classic 600 but without the battery pack, designed for use with modern Polaroid cameras. It offers the same beloved instant photography experience but with enhancements suited to contemporary needs.



The Polaroid Camera: an absolute icon!


The Polaroid Go film, the latest addition, is designed for the world's smallest analog instant camera, the Polaroid Go. This film allows for creativity on the move, with its compact size making it ideal for travel and everyday adventures.

Despite the dominance of digital photography, Polaroid films have maintained their charm, offering a unique and tangible way of capturing memories. They continue to be celebrated for their ability to instantly print moments, providing a physical memento in our increasingly digital world.



Conclusion: Choosing the Right Film Format for Your Photography


As we've journeyed through the diverse world of film formats, from the ubiquitous 35mm to the expansive large format, it's clear that each type offers its own unique set of characteristics and artistic possibilities. Whether you're drawn to the convenience and versatility of 35mm, the exceptional detail of medium format, or the nostalgic charm of formats like 110, 620, and 127, there's a film type to suit every photographer's needs and preferences.

Instax and Polaroid films bring the joy of instant photography, offering a tangible and immediate way to capture and share memories. These formats, with their distinct sizes and styles, cater to a range of creative pursuits, from casual snapshots to artistic projects. On the other end of the spectrum, large format photography invites a slower, more deliberate approach, rewarding photographers with unparalleled image quality and a deep connection to the craft.

In conclusion, the choice of film format is as much about personal preference as it is about the technical aspects of photography.

Which film format have you found to be your favourite, and why does it appeal to you?


  • Most newcomers to film will shoot 35mm and happily stay with that format forever. However, It’s worth trying different formats to see for yourself the differences between them and find your own personal sweet spot. Maybe you will prefer 120 medium format or Polaroid may be more to your liking. Don’t worry about the cost, Film is etremely accessible and the used camera market is full of decent cameras to play with. If you don’t like a camera, you can always sell it for what you paid for it, in some cases maybe more and in others maybe less, that’s always the caveat with the used market. For example, I love using vintage German made 120 medium format folding cameras and I wouldn’t have found this love if I had stayed with 35mm. It can be a little hit and miss, but with due diligence you can find great examples for not a lot of cash. The important thing is to have fun.

  • It looks like there are some mistakes in your initial table. Yes, 35mm film is 35mm wide, but the frame measures 24mm × 36mm which is the key piece of information. Similarly 120 film is 60mm wide, but frames only (generally) use 56mm of this width. APS frames always measure 30.2 × 16.7 mm – the number of exposures does not depend on the selected format – a “H” size frame is always exposed on the film – other formats (C and P) are just produced in printing by cropping the H frame. I guess it’s kind of moot because nobody is shooting APS anymore.
