With a total length of 25 to 35 cm (up to even 42 cm), whereby the tail measures 2/3 of the total length, the Lacerta viridis belongs to the “giants” among the lizards of the family Lacerdidae. The body of the males is a brilliant emerald green (hence its German name) punctuated with small yellow and black spots that are more pronounced upon its back. The throat is clear blue in the adult males in particular during the mating season. The colour of the females is more variable and young animals are rather brown. The belly of the males is yellow, that of the females pale yellow to greenish.
