Pierwsze dwa z brzegu (poza potępioną przez cię wikipedią)

There are many standard widths for 120 camera frames: 645, 6x6, 6x7, 6x8, 6x9, 6x12, and 6x17. These numbers are ostensibly in centimeters although in practice a 6x6 camera such as a Hasselblad will expose a 56 x 56 mm frame.

My personal choice

I like 6x6. I find that I take better photographs when I park the camera on a tripod, look down onto the ground glass, and evaluate the composition as though I were looking at a finished photo.

I am particularly partial to the 6X6 format for several reasons. While 645 cameras are somewhat smaller and lighter it is sometimes awkward to change from horizontal to vertical framing. With 6X6 you essentially have both orientations at the same time and the only real penalty is slightly higher film costs and a couple of less frames per roll. Also, I find that I frequently end-up framing and printing a square or almost square image — something that I find compositionally satisfying, especially when I'm also working with a panoramic camera at a particular location.
