I break the terms down as follows:

roll: This is a camera load of film either before or after exposure and processing and the length is dependent on the gauge and camera, for instance a standard Bolex H-series or B&H model 70 will take a 100 foot roll, but magazines were available for some of these cameras to allow 400 foot rolls, similarly for Regular-8mm most cameras took 25 foot rolls, but a Bolex H-8 would take a 100 foot roll.

reel: This term has a couple of primary definitions in the motion picture world: - 1) A carrier for motion picture film with central hub and support flanges on either side that can be of nearly any capacity, but most commonly within the range of 50 to 2000 feet. A reel can hold a "roll" of film, or several, or edited film, or a print, etc...

- 2) A standard 1000 foot projection reel of the silent film era, thus the terms one-reeler, two-reeler, five-reeler, etc. to describe the length of a theatrically released silent film.

spool: I think this is simply the British-English equivalent of the first "reel" definition above.

- I'm interested to see how others make their distinctions among these terms.

Is there a difference in standard measurements of lengths of film on spools, 
reels and rolls?

A roll of film is for shorter lengths while a reel is for longer ones? for 
example, 100 foot roll and 1000 foot reel

Can you say a spool of film - or have i confused things? Are these terms 
different for super 8, 16 and 35mm?

Any help in untangling and defining this will be much appreciated!
