The film footage calculated on the order form is just an estimate based on the reel diameter.
We will measure the exact footage and adjust the total appropriately.

Some of the 8mm Kodak yellow boxes say 25 ft on them and it can be confusing because there is actually 50 feet on these reels. Most of the boxes actually say 25ft of a double roll. Usually the words "double roll" will be right under "25ft" or might be on the other side of the box. When the film was purchased, it had one 25ft roll of 16mm film in the cartridge. The film was shot one side at a time and then taken out, turned over, put it back in and shot the other side. Kodak then split the 25 feet of 16mm film into one 50 foot roll of 8mm film. So, this is why the 3" reels have 50 feet on them even though the box might say 25ft of a double roll.
