how big can frogs get

Frogs can get impressively large: the biggest living species, the goliath frog , can reach around 32–35 cm (about 12–14 inches) from snout to vent and weigh around 3.3 kg (about 7–7.3 pounds), with some sources reporting specimens close to 4.5 kg.

Biggest frog on Earth

• The goliath frog (Conraua goliath), found in fast-flowing rivers in Cameroon and Equatorial Guinea, is considered the largest frog species in the world.

• Typical large adults are about 32 cm long and around 3.3 kg, but particularly big individuals can reach roughly 34–35 cm and over 7 pounds in weight.

How “big” looks in real life

• A full-grown goliath frog’s body (not counting outstretched legs) is about the length of a sheet of printer paper, and with legs stretched it can measure around 75–80 cm (about 30–31 inches).

• One zoo likens its size to a small house cat, and these frogs can jump close to 3 meters (around 10 feet) in a single leap.

Other giant frog species

• Several other species also get quite large, including the Chilean giant frog, Lake Junin giant frog, African bullfrog, and Blyth’s river frog, with body lengths commonly in the 20–32 cm (8–12.5 inch) range.

• Many well-known “big frogs” like American bullfrogs still top out around 20 cm (about 8 inches) and roughly 0.5–1 kg, noticeably smaller than a true goliath frog.

Overall size range in frogs

• Across all frog species, sizes range from tiny frogs only about 7–8 mm long up to goliath frogs over 30 cm, making them one of the most size-diverse amphibian groups.

• Some prehistoric, now-extinct frogs appear to have been even larger than today’s goliath frog based on fossil evidence, suggesting ancient frogs may once have pushed size limits further.
