Sorry if my question sounds silly, but how to know if my scan is high
bit or low bit?

Open the file in an image editor and see what mode it's in.

Or if you know the pixel dimensions just do the math -- all 10, 12, 14 and 16
bit scans are double the size of 8 bit files because of the way the data is
stored. 8 bit RGB files should be 3x as large as the pixel count, high bit
files twice this size.
