Reel Sizes and Film Formats
Movie film was returned from the photo labs generally on 50 and 100 foot reels. Many were then spliced onto reels of 200, 300, and 400 feet. Some super 8 film was spliced onto 600 and 800 foot reels as well. 16mm film was spliced onto reels up to 14 inches or 2000 feet.

3 Inch Reel = 50 Feet
4 Inch Reel = 100 Feet
5 Inch Reel = 200 Feet
6 Inch Reel = 300 Feet
7 Inch Reel = 400 Feet
8 inch Reel = 600 Feet
10 inch Reel = 800 Feet
12 inch Reel = 1200 Feet
14 inch Reel = 1600 Feet
15 inch Reel = 2000 Feet
This is not exact since some film had a thinner base, and 400 feet would fit on a 6 inch reel.
