What size rice cooker should I buy?

Community consensus on r/RiceCookerRecipes and r/BuyItForLife is to size down rather than up. The 3-cup Zojirushi models are repeatedly praised by solo cooks and couples for footprint and leftovers control, and several owners note that larger 10-cup units cook smaller batches less well. Choose a 5.5-cup if you cook for a family of four; a 3-cup if you mostly cook one to three servings.
