've Always 2 cups cooked rice, but I think it should work great even at 4 or 5 all.
A little tip for all The ones that something "sticky" like their rice, I always do around a quarter of cap more water should be pure as a man,
So with 2 cups rice, 3 1/4 cups of water, then the rice is just that you could eat it with chopsticks!
I would buy this rice cooker again!
