Camera sizes
FPV camera sizes are four named mounting widths. Unlike most fit questions, this one usually has a remedy, because adapter brackets between the sizes are stock items.

The four sizes
The name refers to the mounting width, not the sensor.
| Name | Mounting width | Where it is used |
|---|---|---|
| Nano | 14 mm | 2 inch and under |
| Micro | 19 mm | The most popular size, 3 inch to 5 inch and up |
| Mini | 21 mm | Many frames are designed around this |
| Full | 26–28 mm | Older and larger frames |

Why a size mismatch is a warning here
A frame's camera bay is cut for a particular mounting width, so a camera of the wrong size does not drop in. Brackets that adapt one size to another, a nano into a micro bay being the common case, are ordinary stock items rather than something you have to fabricate.
That is why the planner names the remedy instead of refusing the pairing. A finding that says "this needs a 14 to 19 mm bracket" is more useful than a red cross, and it is more accurate.
