How It Works
Every rice variety absorbs water differently. Long-grain white rice needs a 1:2 ratio (1 cup rice to 2 cups water), while sushi rice only needs 1:1.2. Get the ratio wrong and you end up with mush or crunchy grains.
This calculator adjusts the water amount based on three factors: the rice type you selected, how much you are cooking, and your cooking method. Rice cookers and Instant Pots lose less steam than a stovetop pot, so they need less water.
Rice to Water Ratio Chart
| Rice Type | Water Ratio | Cook Time | Yield (per 1 cup dry) | Texture |
|---|---|---|---|---|
| White long-grain | 1 : 2 | 18 min | 3 cups | Fluffy, separate grains |
| White short-grain | 1 : 1.25 | 15 min | 2.5 cups | Soft, slightly sticky |
| Jasmine | 1 : 1.5 | 15 min | 2.75 cups | Soft, slightly sticky, fragrant |
| Basmati | 1 : 1.5 | 18 min | 3 cups | Long, fluffy, separate grains |
| Brown rice | 1 : 2.5 | 45 min | 2.5 cups | Chewy, nutty |
| Wild rice | 1 : 3 | 50 min | 3.5 cups | Firm, chewy |
| Sushi rice | 1 : 1.2 | 15 min | 2.5 cups | Sticky, glossy |
| Arborio (risotto) | 1 : 3.5 | 20 min | 3 cups | Creamy, starchy |
All cook times are for stovetop. Rice cooker times are ~15% shorter. Instant Pot times are ~50% shorter.
Stovetop vs Rice Cooker vs Instant Pot
| Method | Water Adjustment | Time Adjustment | Best For |
|---|---|---|---|
| Stovetop | Full ratio (no change) | Full time | Any rice type, most control |
| Rice Cooker | -10% water | ~15% faster | Set-and-forget, consistent results |
| Instant Pot | -15% water | ~50% faster | Brown rice, wild rice, speed |
Stovetop gives you the most control. Bring water to a boil, add rice, reduce to low, cover, and do not lift the lid until the timer goes off. Let it rest 5 minutes after cooking.
Rice cookers regulate temperature automatically and switch to "keep warm" when done. They lose less steam, so you use slightly less water. Most models handle white and sushi rice well.
Instant Pot pressure-cooks rice, which cuts cook time significantly. It is especially good for brown and wild rice, which take 45-50 minutes on the stovetop but only 22-25 minutes under pressure. Use natural release (10 minutes) for best texture.
FAQ
Do you rinse rice before cooking?
Yes, for most types. Rinsing removes surface starch, which prevents clumping and gives you fluffier grains. Put the rice in a fine mesh strainer and run cold water over it until the water runs clear (about 30 seconds). The exception: do not rinse arborio rice for risotto — you want that starch for the creamy texture.
Why is my rice mushy?
Three common causes: too much water, lifting the lid during cooking (releases steam and disrupts the ratio), or not using a tight-fitting lid. Measure water precisely — do not eyeball it. If you use a rice cooker, make sure you are using the correct water line for your rice type.
How much rice per person?
About 0.5 cup of dry (uncooked) rice per person as a side dish. That yields roughly 1-1.5 cups cooked, depending on the type. For rice as the main dish (like a rice bowl), plan 0.75-1 cup dry per person.
Can you use broth instead of water?
Absolutely. Chicken broth, vegetable broth, or bone broth all work as a 1:1 replacement for water. The ratios stay the same. Using broth adds flavor without extra effort — it is one of the easiest upgrades for plain rice.
