All sizes are are given in millimetres.

Unfortunately due to not having access to all the specifications each film size and there being so much conflicting data on the internet, the sizes may not completely accurate. If you find any of the information to be wrong, please let me know.

Update: I now have the specifications for Super 8 & Standard 8. The sizes used in the comparison are of the camera image area and not the projector image areas which is slightly smaller.
