135 film
photographic film format provided in a cartridge, also known as 35 mm film from the width of the film strip; most common analog (chemical) film used during the era of analog photography by both amateur und professional photographers
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film with a film gauge of 35 millimetres (1.4 inches) loaded into a standardized type of magazine (also referred to as a cassette or cartridge) for use in 135 film cameras.
The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 120, 828, 126, 110, and APS, it remains the most popular film size today.
The size of the 135 film frame with its frame's aspect ratio of 2:3 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as "full frame". Even though the format is much smaller than historical medium format and large format film, being historically referred to as miniature format or small format, it is much larger than image sensors in most compact cameras and smartphone cameras.
The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'.
History
35 mm still cameras
The 135 film size is derived from earlier still cameras using lengths of 35 mm movie film, which had the same size but with different perforations. The 35 mm film standard for motion picture film was established in Thomas Edison's lab by William Kennedy Laurie Dickson. Dickson took 70 mm film stock supplied by George Eastman's Eastman Kodak Company.
Begin with the source’s own compact description: “135 film” is photographic film format provided in a cartridge, also known as 35 mm film from the width of the film strip; most common analog (chemical) film used during the era of analog photography by both amateur und professional photographers. The dossier treats that line as a proposition to test through film, photographic and format, not as a finished interpretation.
Why this record matters
The phrase “photographic film format provided in a cartridge, also known as 35 mm film from the width of the film strip; most common analog (chemical) film used during the era of analog photography by both amateur und professional photographers” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q1051557. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1934 and 1007.
Titles can refer to several editions, objects or performances, making precise identification essential before interpretation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
