How much film do I have on my film reels?
How to tell the length of
your film based on the width of your
film
reels
As you unpack your box of film,
you will find that your film is
currently on 3-inch film
reels, 5-inch film
reels, or 7-inch
film reels. When your film
was first developed, chances are it
was delivered back to you or your
parents on a 3-inch reel (which is
why you may have so many!). Each of
these 3-inch reels holds 50 linear
feet of film, which equates to
roughly 3-4 minutes of video,
depending on
what type of film it is.
If the 3-inch reels were viewed and
spliced together, they obviously
lengthened and needed to be put onto
larger reels. The 5-inch reels hold
approximately 200 feet of film (or
15 minutes of footage), and the
7-inch reels hold approximately 400
feet of time (or 30 minutes of
footage).
