Best Rice Cooker by Size: How Many Cups Do You Need?
Quick answer: Choose a 3-cup rice cooker for 1 to 2 people, 5.5 to 6 cups for a family of 3 to 6, and 10 cups for large families or entertaining. If you are between sizes, go up one size, since a cooker works best when it is at least a third full and a bigger one costs little more.

How rice cooker sizes are measured
Rice cooker size is the number of cups of uncooked rice it can hold, and it makes roughly double that in cooked rice. A 5.5-cup cooker makes about 11 cups cooked. Two things trip people up:
- The cup is not a US cup. The measuring cup supplied with most cookers holds 180 ml (about ¾ of a US cup). Use it for both rice and the water lines.
- Some sizes are listed as cooked cups. An 8-cup (cooked) cooker holds only 4 cups of uncooked rice. Always check which one the label means.
For the amounts of water, see how much water to use for rice.
What to consider when choosing a size
- Household size and appetite: estimate 1 to 1½ cups of cooked rice per adult as a side, more if rice is the main part of the meal.
- How often you cook: if you cook daily, a compact cooker that matches your portion cooks more evenly than an oversized one.
- Other uses: steaming, oats and quinoa need room because grains expand. Do not fill past the max line.
- Counter space: a 10-cup cooker is much larger than a 3-cup one, and induction and pressure models are bulkier still.
- Minimum amount: most cookers need at least about 1 cup of uncooked rice to cook well. A tiny batch in a big cooker can dry out.
