Dwarf jade and jade share a name, not a family. Regular jade (Crassula ovata) is a South African succulent. Dwarf jade (Portulacaria afra) comes from the same corner of southern Africa but belongs to a different plant family: Didiereaceae in current classifications (formerly Portulacaceae), not jade's Crassulaceae. They look similar at a glance — thick, fleshy leaves on succulent stems — but as bonsai subjects, dwarf jade is the easier tree to keep in scale: its leaves are much smaller, so it stays in proportion in a small pot.
Let's clear up the naming mess and talk about why.
Check leaf size first, then the stems. Dwarf jade (Portulacaria afra) usually has small, round to oval leaves about ½-¾ in (1-2 cm) long on thin, tapering stems. Jade (Crassula ovata) usually has larger oval leaves, about 1-3½ in (2.5-9 cm), on thick stems that keep a similar diameter.

How sure is this?
Same on both, so not a tell:
Why it matters: Pet owners need to know which one they have. The ASPCA lists jade plant as toxic to cats and dogs. No ASPCA listing was found for dwarf jade (Portulacaria afra), which is not proof it's safe. Otherwise care is close: both come inside once nights drop toward 50°F (10°C).

Leaf size is the usual first tell, though cultivars overlap. Dwarf jade leaves usually run about ½-¾ inch (1-2 cm); regular jade leaves are usually larger, about 1-3½ inches (2.5-9 cm). In bonsai, smaller leaves mean better proportionality and a more convincing miniature tree. Dwarf jade looks like a scaled-down tree. Regular jade looks like... a succulent in a pot. That difference matters.
Both take pruning well. Dwarf jade buds out wherever a branch or even a leaf comes off, so cutting just above a pair of leaves keeps it almost any size or shape. Jade benefits from pruning too: cut stems back to a side branch in spring to keep it compact, which also helps the trunk develop.
Wiring doesn't separate them. Both have brittle stems, so wire young green shoots gently and sparingly, if at all. On both trees most shaping is clip-and-grow.
Trunk character develops differently. Regular jade gets fat — that bulbous succulent trunk swells impressively. Dwarf jade builds a slimmer trunk: its reddish-brown stems mature to gray, with woody tissue inside. Jade's stems turn brown and woody with age too, and old jade bark peels in horizontal strips, so bark is no reason to pick one over the other.
Drought tolerance is close but not identical. Both store water in their leaves and go weeks without irrigation. Regular jade stores more per leaf (bigger, thicker leaves) and technically survives longer neglect. Dwarf jade dries out a touch faster with its smaller leaves. But honestly, both are so drought-tolerant that this rarely matters in practice.
Get dwarf jade (Portulacaria afra). Its smaller leaves keep the tree in scale in a small pot, and that's the difference that matters for styling. Both take pruning well and both have brittle stems, so on those it's a tie.
Regular jade is fine if you already own one or you specifically want that chunky succulent look. But if you're choosing between them at a nursery? Dwarf jade. Don't overthink it.
