Reel Sizes and Time

After transferring film for over 25 years one of the most common questions we hear is: What size reels do I have and how much time is on each reel? 8mm film reels are usually one of the following – 3 inches = 50 feet, 5 inches = 200 feet, and 7 inches = 400 feet.

When we want to estimate the amount of time that a film transfer will be the rule of thumb I use is 3 minutes per 50’ of 8mm or super 8 film. This is not exact to the second but will get you close enough to know how much time you have. If you have 16mm film then the time will be less since it runs at twice the speed. So a 50’ reel of 16mm will be 1.5 minutes in running time.
