I used to eyeball rice and water the same way every time, until I actually cooked six different rice types side by side and realized how differently each one drinks. Basmati wants far less water than brown rice. A rice cooker wants less than the stovetop. Below is the reference I now keep taped inside the cupboard, plus the calculator above if you'd rather just plug in numbers.
Rice to water ratio, by type and method
All ratios assume rinsed rice and sea-level cooking. Ratio is rice : water.
| Rice type | Stovetop | Rice cooker | Instant Pot |
|---|---|---|---|
| White (long-grain) | 1 : 1.5 | 1 : 1.25 | 1 : 1 |
| Basmati | 1 : 1.5 | 1 : 1.25 | 1 : 1 |
| Jasmine | 1 : 1.25 | 1 : 1 | 1 : 1 |
| Brown | 1 : 2 | 1 : 2.25 | 1 : 1.25 |
| Wild | 1 : 3 | 1 : 2.75 | 1 : 1.5 |
| Sushi | 1 : 1.1 | 1 : 1 | 1 : 1 |
Cook times, by type and method
| Rice type | Stovetop | Rice cooker | Instant Pot |
|---|---|---|---|
| White (long-grain) | 18–20 min | 20–25 min | 4 min + 10 min NR |
| Basmati | 15–18 min | 18–20 min | 4 min + 10 min NR |
| Jasmine | 15 min | 15–18 min | 3 min + 10 min NR |
| Brown | 40–45 min | 45–50 min | 22 min + 10 min NR |
| Wild | 45–50 min | 50–55 min | 25 min + 10 min NR |
| Sushi | 15 min + rest | 15–20 min | 3 min + 10 min NR |
NR = natural pressure release.
Why your rice cooker needs less water
- A sealed rice cooker loses almost no water to evaporation, so it needs less than an open stovetop pot for the same rice.
- An Instant Pot seals even tighter and cooks under pressure, so it needs the least water of the three — usually close to 1:1.
- Most rice cookers have cup markings printed inside the bowl. If yours has them, trust those over a generic ratio — they're calibrated to that specific model.
- Rinsing rice removes surface starch, and a little water clings to the grain afterward — for firmer results, reduce water by about a tablespoon per cup.
Rice types at a glance
White
The baseline ratio most other rice is measured against — 1:1.5 on the stovetop.
Basmati
Slender and lower-starch, so it drinks less water than standard long-grain white.
Brown
The bran layer is tougher, needing more water and roughly double the cook time.
Wild
Technically a grass seed, not rice — the thickest husk means the most water and time.
Frequently asked questions
How much water do I need for rice in a rice cooker?
It depends on the rice. White, jasmine, and sushi rice typically need about 1 cup of water per cup of dry rice in a rice cooker. Basmati needs slightly more, around 1:1.25, and brown rice needs closer to 1:2.25 because the bran layer takes longer to absorb water. Use the calculator above for the exact figure.
How long does rice take to cook in a rice cooker?
White, jasmine, and sushi rice generally finish in 15–20 minutes on a standard rice cooker cycle. Basmati is similar, around 18–20 minutes. Brown rice takes considerably longer, typically 45–50 minutes, and wild rice can run 50–55 minutes.
What is the water ratio for basmati rice?
On the stovetop, use about 1 to 1.5 cups of water for every cup of dry basmati, depending on whether it's soaked first. In a rice cooker, 1:1.25 is a reliable starting point.
How do I cook brown rice in a rice cooker?
Use roughly 2.25 cups of water for every cup of dry brown rice, and select your rice cooker's "brown rice" setting if it has one — it runs a longer cycle to fully soften the bran layer.
Do I really need less water in a rice cooker than on the stovetop?
Yes. An open pot on the stove loses water to steam throughout cooking, so recipes compensate with extra water. A sealed rice cooker loses very little, so it typically needs 20–30% less water for the same rice.
Why does jasmine or basmati rice need less water than plain white rice?
Jasmine and basmati are bred to be more slender with a different starch structure than standard long-grain white rice, so they absorb water more readily and need less of it to fully hydrate.
