Photographic Film Formats & Roll Standards
6 items
Standardized analog photographic film types defined by ISO 1007 (135 35mm), ISO 732 (120/220 medium format roll film, 110 pocket cartridges), and ISO 1010 (4x5 and 8x10 large format sheet films), covering perforation pitches, spool geometries, and DX-coding standards.

135 Film (35mm Still Film / ISO 1007)
135 Film (standardized under ISO 1007) is the most popular photographic film format in history, consisting of a 35.0 mm wide cellulose acetate or polyester strip with standard KS-1870 sprocket perforations housed in a light-tight metal cassette. Capturing standard 36 × 24 mm frames in 24 or 36 exposure lengths, it utilizes electrical DX-barcode contacts to auto-set ISO speed and exposure latitude.

120 Roll Film (Medium Format / ISO 732)
120 Film (standardized under ISO 732, introduced by Kodak in 1901 for the Brownie No. 2) is the universal medium format roll film standard, featuring a 61.5 mm wide unperforated film strip attached to continuous light-tight backing paper wound on a plastic/metal spool. Capturing multiple frame formats including 6×4.5 cm (16 exp), 6×6 cm (12 exp), 6×7 cm (10 exp), and 6×9 cm (8 exp).

220 Roll Film (Double-Length Medium Format)
220 Film (standardized under ISO 732, introduced in 1965) is a double-length medium format roll film that yields twice the exposures of 120 film (24 exposures at 6×6 cm, 20 exposures at 6×7 cm). By eliminating the backing paper along the body of the film (retaining paper only at the black leader and trailer), twice as much film fits onto the same 25mm spool.

4×5 Large Format Sheet Film (ISO 1010)
4×5 Sheet Film (standardized under ISO 1010) is the benchmark large format photographic film standard, measuring exactly 3.90 × 4.90 inches (99.0 × 124.5 mm nominal for 4×5 inch film holders) with a massive 12,325 mm² active negative area (~14.3× larger than 35mm full frame). Loaded individually into dual-sided dark slides, it features edge notch codes for emulsion identification in total darkness.

8×10 Ultra-Large Format Sheet Film
8×10 Sheet Film (standardized under ISO 1010) is the pinnacle of ultra-large format analog photography, measuring 7.90 × 9.90 inches (200.5 × 251.5 mm nominal) with a gargantuan 50,425 mm² negative surface area (~58.4× larger than 35mm full frame). Famous for direct contact printing with zero enlargement grain in platinum/palladium and silver gelatin printing.

110 Pocket Film Cartridge (ISO 732)
110 Film (introduced by Kodak in 1972 for the Pocket Instamatic system) is a subminiature drop-in film cartridge containing a 16.0 mm wide single-perforated film strip with a 13 × 17 mm frame format (approx. 1/4 the area of 35mm). Featuring integral supply and take-up chambers with backing paper, it requires no rewinding.
