Frame size[edit source]

116 is a roll film introduced by Eastman Kodak in 1899 for 2 3/4×4¼ inch negatives (the nominal size in centimeter is 6.5×11 cm)

Rebollo fr asks: Is it an exact conversion? Or is it optimistic, as for 6x9?

If the inch description is accurate (and not itself a simplification), then the dimensions would be about 6.35 x 10.8 cm.

It's imaginable that the centimetre sizes are accurate and that the inch sizes are a conventional translation. But I find this unlikely, as Kodak probably worked in inches.

Another possibility is that back when these cameras were made different manufacturers had different ideas of how to use the film, so one should instead say that for example Kodak cameras produced X × Y inches (close to a×b millimetres); while Voigtländer cameras produced d×e millimetres (which, if anyone is interested, is close to V × W inches). Yes, that wouldn't be hard to imagine: after all, I believe that the negative size for Barnack Leicas is larger than 24×36 in at least one dimension, and I know I have a "66" camera whose negatives are bigger than 56×56mm. -- Hoary 05:09, 19 June 2006 (EDT)

Thanks for the conversion, I was too lazy to do it.
What you say about different makes making different exposure chambers is not unlikely if the difference was tiny (maybe one millimeter or even two). It is hard to imagine a larger difference because the paper backing was the same for everyone, based on a Kodak standard: any big difference (between 56mm and 6cm for ex.) would have resulted in overlap problems. What I'm saying is only valid for the red window era, of course. After the advent of auto-stop advance, any maker could do what pleased him. --Rebollo fr 05:35, 19 June 2006 (EDT)
