The Polaroid 20×24 camera is a very large instant camera made by Polaroid, with film plates that measure a nominal 20 by 24 inches (51 cm × 61 cm), giving the camera its name, although at least one camera takes pictures that are 23 by 36 inches (58 cm × 91 cm).

The most common large format is 4×5 inches (10.2x12.7 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Graphic, among others. Less common formats include quarter-plate (3.25x4.25 inches (8.3x10.8 cm)), 5×7 inches (12.7x17.8 cm), and 8×10 inches (20×25 cm); the size of many old 1920s Kodak cameras (various versions of Kodak 1, 2, and 3 and Master View cameras ...
When the Polaroid SX-70 was introduced in 1972 it used a film pack of 10 film sheets where each film sheet had a size of 3.5 x 4.25 in 2 with a picture area of 3.125 x 3.125 in 2 and ASA film speed of 150. [14]
A good cell phone camera with typical pixel size 1.1 μm (Samsung A8) would have about 3 times worse SNR due to shot noise than a 3.7 μm pixel interchangeable lens camera (Panasonic G85) and 5 times worse than a 6 μm full frame camera (Sony A7 III). Taking into consideration the dynamic range makes the difference even more prominent.
(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
Because of the relatively large size of the imaging area these media provide, they can record higher resolution images than most consumer digital cameras. Based upon the above pixel density, a medium-format film image can record an equivalent resolution of approximately 83 million pixels in the case of a 60 x 60 mm frame, to 125 million pixels ...
