What are the dimensions of 122 film?

[eharriett]

I'm trying to figure something out here and Google and Wikipedia are no help. Does anyone know what the width of 122 film is? I can easily find the exposure size, but not the size of the film itself. My guess going by exposure size is it is 85mm, with the backing paper being maybe 1 mm wider. Can anyone confirm?

Thank you.

Spool length will get you close but is slightly larger than the film.
