Understanding Film and Sensor Sizes
Photography has been around for over 125 years and in that time many different mediums have been used to capture images. Among those different mediums we have seen many different 'film' sizes. 35mm was created to standardize professional level film and it was mostly successful but it wasn't produced until 1934 and it only slowed down the creation of film formats. Below are a few quick reference tables. For more in depth info I suggest a visit to http://www.earlyphotography.co.uk.
