However, here's a general idea:
* Small: Some frogs, like the tiny rain frog, can be as small as 1 centimeter long.
* Medium: Most frogs, like the common green frog, are around 5-10 centimeters long.
* Large: Some frog species, like the Goliath frog, can grow up to 30 centimeters long!
To get a more specific size, you'll need to know the particular species of frog you're interested in.
