How big can a male Syrian hamster get?

[flogging_molly]

I have a boy Syrian hamster he's about 5 inches long and he's only 3 months, how big will he grow to?

It depends on how long his growth spurt lasts, it's different in all hamsters. My Biscuit is nearing 7 inches and he's 5-6 months old. (Estimate because I got him from a PETsMART)

Some Syrians are over 20 cm in length when fully grown. A lot depends on their genetics (parents etc).
