The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 20 to 203 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

Land
45 × 22cm
Water, at least 9 cm deep
22 × 22cm

Minimum, and for two animals — which is how the standard states it. Bigger is always better. Around 22 cm tall on average.

The standard gives 10 × 5 body lengths of land and 5 × 5 of water, for two animals.

For each further animal the standard asks for another 9 × 9 cm of land and 9 × 5 cm of water.

Swiss Tierschutzverordnung (TSchV), SR 455.1, Anhang 2, Tabelle 6 — legally binding minimum enclosure sizes for amphibians, given as multiples of total body length and stated for two animals.

From this animal’s own snout-vent length, which for a frog is its body length of 1.75 in (44.8 mm) — how this is worked out.
