A rice water ratio calculator gives you the exact amounts needed for your specific rice type, cooking method, and batch size. Different varieties absorb different amounts of water — what works for jasmine fails with sushi rice.
Rice-to-Water Ratios Reference (Stovetop, per 1 cup dry)
| Rice Type | Water (cups) | Cook Time | Yield |
|---|---|---|---|
| White long-grain | 1.75 | 18 min | 3 cups |
| Jasmine | 1.5 | 15–18 min | 3 cups |
| Basmati | 1.5 | 18–20 min | 3 cups |
| Brown rice | 2.25 | 40–45 min | 3 cups |
| Sushi / Calrose | 1.25 | 18 min | 2.5 cups |
| Wild rice | 3 | 45–55 min | 3–4 cups |
How to Cook Perfect Rice
The most important step before cooking is rinsing. Run water over dry rice until it runs clear — this removes excess surface starch that causes gummy rice. Basmati and jasmine particularly benefit from rinsing. Sushi rice is the exception; it retains starch for stickiness.
Stovetop Method
Bring water to a boil, add rice and a pinch of salt, reduce to the lowest simmer, cover tightly, and cook for the indicated time. Do not lift the lid. Remove from heat and let steam for 10 minutes. Fluff with a fork.
Rice Cooker Method
Use the rice cooker's measuring cup (it's often smaller than a standard cup). Fill water to the line for your rice type. Most rice cookers switch to warm mode automatically when done.
Instant Pot Method
White rice: 1:1 ratio, 3 minutes high pressure, natural release for 10 minutes. Brown rice: 1:1.25 ratio, 22 minutes high pressure, natural release. The Instant Pot uses less water because none evaporates.
FAQ
How much water for 1 cup of white rice?
Standard long-grain white rice: 1 cup rice to 1.75–2 cups water on the stovetop. Rice cooker: use the rice cooker cup and water lines. Different rice varieties need different ratios — use this calculator for your specific type.
Why is my rice always mushy?
Too much water is the most common cause. Rinse rice before cooking to remove excess starch, use the correct ratio, and don't lift the lid during cooking. Let rice steam for 5-10 minutes off heat after cooking.
What is the ratio for brown rice?
Brown rice requires more water: about 1 cup rice to 2–2.25 cups water, and longer cooking time (40-45 minutes vs 18-20 for white). The bran layer absorbs more water and takes longer to soften.
How much water for rice in an Instant Pot?
Instant Pot uses less water than stovetop because little steam escapes. White rice: 1:1 ratio (equal water and rice). Brown rice: 1:1.25. Cook on high pressure for 3 minutes (white) or 22 minutes (brown) with natural release.
