A toad is a squat amphibian with dry, warty skin and short legs, while a frog is a smaller, smoother-skinned amphibian with long hind legs built for jumping. Skin is the quickest tell: bumpy and dry usually means toad, smooth and moist usually means frog.
The core difference
Toad and frog both name amphibians in the same broad family, but toad refers to the drier-skinned, squatter type and frog to the smoother-skinned, longer-legged type.
- toad — a squat, warty-skinned amphibian related to frogs, typically with drier skin and shorter legs: a toad hopped across the garden path after the rain.
- frog — a small tailless amphibian with long hind legs built for jumping and swimming: a frog leapt into the pond as we walked past.
How to tell them apart
Because toads are technically a type of frog, the two words overlap rather than sitting neatly opposite each other, which is why the same pond visitor can get called either one. Looking at the skin and legs settles most cases: warty and dry with short legs points to toad, while smooth and damp with long legs points to frog.
The words branch out further in ways that have nothing to do with the animal. Frog also names the part of a violin bow the player grips and, informally, the act of unpicking knitting, while toad can be used as an insult for an unpleasant person.
