How many photographs fit on a 120 film roll?
It depends on the camera frame size: commonly 15-16 at 6x4.5, 12 at 6x6, 10 at 6x7, 8 at 6x9, 6 at 6x12 and 4 at 6x17.
How many photographs does a half-frame camera make?
A half-frame camera usually makes about 48 photographs from a 24-exposure roll and about 72 from a 36-exposure roll.
Why can the final exposure count differ?
Film length, loading position, frame spacing and the camera transport mechanism can change the count by one or more frames.
Counts are practical estimates based on common 135 and 120 camera formats; individual cameras can differ. Last reviewed: July 2026.
