Rice to Water Ratio Chart
Recommended ratios for stovetop cooking using the absorption method.
| Rice Type | Ratio (Rice:Water) | Cook Time | Yield (per cup dry) | Notes |
|---|---|---|---|---|
| Long Grain White | 1 : 1.5 | 15-18 min | ~3 cups | Most versatile, fluffy |
| Short Grain White | 1 : 1.25 | 15-18 min | ~3 cups | Stickier, good for bowls |
| Basmati | 1 : 1.5 | 15-18 min | ~3 cups | Rinse well, soak 20 min |
| Jasmine | 1 : 1.25 | 12-15 min | ~3 cups | Fragrant, slightly sticky |
| Sushi Rice | 1 : 1.1 | 15-18 min | ~2.75 cups | Rinse until clear, season after |
| Brown Rice | 1 : 2.25 | 40-50 min | ~3.5 cups | More water and time needed |
| Wild Rice | 1 : 3 | 45-55 min | ~3.5 cups | Technically a grass seed |
| Arborio (Risotto) | 1 : 3-4 | 18-25 min | ~3 cups | Add liquid gradually, stir |
| Sticky Rice | 1 : 1.1 | 20-25 min | ~2.5 cups | Soak 4+ hours first |
| Parboiled | 1 : 2 | 20-25 min | ~3 cups | More forgiving, harder to mess up |
How to Use This Calculator
- Enter Your Rice Amount (cups, dry): Start by entering your rice amount — this is the primary input for the calculation.
- Fill In Additional Details: Complete the remaining fields: rice type, cooking method, or enter number of servings. Each value refines the calculation for greater accuracy.
- Click Calculate: Hit the Calculate button to run the numbers. Results appear instantly below.
- Review Your Results: Check your water needed, rice, ratio. Use these figures to inform your next decision or compare against alternative scenarios.
How It Works
The perfect rice-to-water ratio depends on the rice variety, grain length, and cooking method. Too much water makes mushy rice; too little makes it crunchy. Getting the ratio right is the single most important step.
The basic rule:
- Long grain white: 1 cup rice to 1.5-1.75 cups water
- Basmati / Jasmine: 1 cup rice to 1.25-1.5 cups water (less water for fluffier grains)
- Short grain / Sushi: 1 cup rice to 1.1-1.25 cups water
- Brown rice: 1 cup rice to 2-2.5 cups water (the bran needs more water and time)
- 1 cup dry rice yields approximately 3 cups cooked (varies by type)
These ratios assume absorption method cooking (no draining). Rice cookers and Instant Pots may need slightly less water because they lose less steam. Always let rice rest 5-10 minutes after cooking before fluffing.
Tips & Considerations
- Double-check your rice amount before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both water needed and rice — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to perfect your recipes.
- If you're unsure about your or enter number of servings, start with a conservative estimate and adjust from there.
Frequently Asked Questions
What is the ratio of rice to water?
For standard long grain white rice, use 1 cup rice to 1.5 cups water. For brown rice, use 1:2. For basmati and jasmine, use 1:1.25 to 1:1.5. The ratio varies by rice type because different grains absorb different amounts of water.
How much water for 2 cups of rice?
For 2 cups of long grain white rice, use 3 cups water (1:1.5 ratio). For basmati, use 2.5-3 cups. For brown rice, use 4-5 cups. For sushi rice, use 2.25-2.5 cups.
Should I rinse rice before cooking?
Yes, rinsing removes excess surface starch that causes gummy, sticky rice. Rinse 2-3 times until the water runs mostly clear. The exception is risotto rice (arborio) — you want that starch for creaminess.
How much cooked rice does 1 cup dry make?
1 cup of dry rice yields approximately 3 cups cooked for white rice, 3-3.5 cups for brown rice, and 2.5-3 cups for wild rice. This can vary slightly by brand and cooking method.
Why is my rice mushy?
Mushy rice is caused by too much water, stirring during cooking (which releases starch), or cooking too long. Use the correct ratio for your rice type, don't lift the lid during cooking, and let it rest 5-10 minutes off heat before fluffing.
Do I need to adjust water at high altitude?
Yes. At elevations above 3,000 feet, water boils at a lower temperature and evaporates faster. Add 2-4 tablespoons of extra water per cup of rice and increase cooking time by 3-5 minutes.
