Bacteria are in general 2 to 5 micrometers in length, 1 to 3 micrometers in width.
Fungi are generally 2.5 micrometers in width, can be miles in length.
Protozoa vary from 5 micrometer width for the little guys to 100 micrometers for the big guys, all sorts of shapes.
Soil nematodes are 10 to 50 micrometers width, to 10 to 20, up to 1 cm length.
Magnifications were 1000X for the stained bacterial pictures, to 400X for some of the bacteria, 200 X for the fungi, to 6 X for the arthropods.
Does that help? Sorry I was so slow getting back.
