Often when we are asked to convert microfiche to digital formats like PDF and TIFF, the people having them converted don't know the size of the documents contained on the microfiche themselves. So here's a short guide to what size images are stored on microfiche.
What size are the images stored on microfiche?
This can depend on the type of microfiche that you have. There are most commonly two sizes; 16mm and 35mm.
Obviously the larger the fiche is the larger the images are that will go onto it. 16mm microfiche almost always contain A4 documents or documents of a similar size or sometimes 2 A5 documents go on there to save the amount of film negatives being used.
35mm contain anything from size A3 up to A0+ depending on how much the ratio of it is reduced when transposing it onto the negative. 35mm microfiche were usually used by the likes of architects and anyone else that works with large format images.
How do I know what type of microfiche I have?
It really is as simple as measuring them. If they measure 16mm (1.6cm) or 35mm (3.5cm) then that's what they are. Much more rarely you'll find some microfiche sleeves that contain both 16mm and 35mm negatives. These are known as Combi fiche. All the different types of microfiche can be seen here.
