Rice cooker water ratios by rice type

What published sources say about water for white and brown rice in a rice cooker, why the numbers differ, and habits they agree on.

Short answer

Sources do not agree on one number for white rice. Start with the water lines inside your cooker's pot or the manual, because ratios vary by model. If your cooker has no lines, use the table below as a starting point and adjust to how soft you like the rice.

What the sources say, per 1 cup of rice

These are the figures from each page. They are not our own testing. A chef quoted by Food Republic gives different figures for the stovetop and says that for a rice cooker he follows the machine's cup-line guide.

RiceWater, per source
Long-grain white (including jasmine and basmati)Good Housekeeping: 1 cup. Panasonic: about 1 1/2 cups for long-grain, 1 1/4 to 1 1/2 for white rice in general.
Short-grain whiteGood Housekeeping: 1 cup.
BrownGood Housekeeping: 2 1/4 cups.

The cup

The cup that comes with a rice cooker is usually smaller than a standard cup. Good Housekeeping says it is often 3/4 cup. Use the same cup for the rice and the water, and the ratio holds either way.

Habits the sources share

How long it takes

Good Housekeeping puts 1 cup of white rice at 20 to 30 minutes and brown rice at 45 to 50 minutes. The cooker stops by itself when the water is gone.
