In general, Eukaryotic cells are a fair bit larger than Prokaryotic cells (if you look at them under the microscope, you can generally see details inside Eukaryotic cells, whereas Prokaryotes are just tiny dots).
Prokaryotic cells are 0.2-2 uM (micrometers or 10^-6)
Eukaryotic cells are 10-100 uM
Give or take, eukaryotic cells are 50-100 times bigger than prokaryotic cells.
