What Size Rice Cooker Do You Need? 3 vs 5.5 vs 10 Cups (with Calculator)

Short answerMost households of two to four people should buy a 5.5-cup rice cooker. The catch is that the 5.5 means Japanese rice cups of 180 mL, which are smaller than a 240 mL US cup.

QUICK CHECK

What size rice cooker do you need?

A Japanese rice cup is 180 mL. A US measuring cup is 240 mL, so 1 US cup of rice is about 1.33 rice cups. The leftover multiplier is our own rule of thumb.

01Rice cups are not US cups

Zojirushi states that capacity is measured with its 180 mL rice measuring cup, using raw short-grain white rice. The US nutrition labeling standard treats 1 cup as 240 mL. So a "5.5-cup" cooker holds about 4 US cups of raw rice, not 5.5.

Always measure with the cup that came in the box. The water lines inside the pot assume that cup.
