Monerujo has a feature called PocketChange which splits change into multiple outputs. This increases the transaction size, but by how much? And do other wallets have this type of feature?

A typical 1 input 2 output transaction is ~1.49 kB (ref).
A 1 input 16 output transaction is ~3.2 kB (ref, assume this is a PocketChange transaction).
Therefore in this example, a PocketChange transaction is just over twice the size of a normal transaction.
It's worth pointing out that it's the input count that is the more defining aspect to overall transaction size, as each input requires a ring signature, but PocketChange is about creating more outputs, not inputs.

wouldn't one be able to reveal if a user just made a pocket change transaction? how does ring signature hide things if a transaction contains 1 input and 16 outputs.– Patoshi パトシ ♦Commented Nov 13, 2023 at 20:42

"how does ring signature hide things if a transaction contains 1 input and 16 outputs" The same as any 1 in, 16 out tx. And remember, that 1 input is in a ring of 16 other possible inputs; each input has its own ring. Commented Nov 14, 2023 at 1:52
