Four to five inches, and famously dumpy
A White's tree frog finishes growing at about 4 to 5 inches in body length, and what the tape measure misses is the bulk: this is one of the heaviest tree frogs in the hobby, with a broad head, a thick fold of skin draping over the ear, and a rounded body that earns it the nickname dumpy tree frog. Females grow larger and plumper than males, and a big female sitting on a branch has real presence, more like a small green paperweight than a delicate climber. Males announce themselves by calling, with a loose throat pouch, while staying a touch smaller and leaner through the body.
Growth from froglet to handful
Froglets leave the water tiny and grow fast, passing through a lanky juvenile stage before the characteristic heaviness arrives. With steady feeding and warmth, most White's tree frogs approach adult length within their first year and then continue filling out, the skin fold and rounded belly developing as the frog matures. Because they are such willing eaters, growth can overshoot into obesity, visible as fatty ridges above the eyes that begin to cover them. A healthy adult is plump but still clearly shaped, able to climb and jump without hauling obvious excess around with it.
Perches and space that hold an adult's weight
Housing must be built for the finished frog's mass as much as its length. Branches and ledges should be wide, smooth, and firmly fixed, because a heavy adult landing from a jump will flex or topple anything flimsy, and broad leaves alone will not support it for long. A roomy, tall enclosure with a large shallow water bowl for nightly soaking suits the adult, and smooth surfaces matter because this species' skin is prone to abrasion from rough decor. Give each frog its own favored perch level, since adults are tolerant tankmates but still compete for the best soaking and sleeping spots. Misting in the evening matches the hours when this frog wakes, drinks droplets from leaves, and begins to hunt.
Feeding a big, enthusiastic frog
Adults take large crickets, roaches, and occasional treats, snapping at almost anything that moves, including, famously, keeper's fingers at feeding time. That enthusiasm makes portion control the keeper's job: feed measured amounts on a schedule rather than offering food whenever the frog watches you, and use tongs to keep meals accurate and fingers safe. Night is feeding time, and a healthy adult should hunt actively and hold a steady, rounded shape between meals. A frog growing suddenly slimmer, or refusing food it would normally lunge for, warrants a check of temperatures and a vet visit if it persists.
A personable frog whose notes are worth keeping
White's tree frogs are long-lived and develop individual habits, favorite perches, preferred prey, and a tolerance for gentle handling that varies frog to frog. Recording those details, along with final adult size and weight, gives the frog continuity if its home ever changes across its long life. On that day, KinsLe Transferrable Profiles sends its profile to the new keeper with those habits and routines recorded, so a much-loved frog settles in without starting from scratch.
