Rice-to-Water Ratio Calculator: Stovetop, Rice Cooker and Instant Pot
Rice-to-Water Ratio and Cooking Chart
All ratios below are rice:water by volume. Water amounts are for 1 US cup (236.6 ml) of dry rice. These are starting points for plain rice; package directions and appliance fill lines take priority.

Plain wild rice is not the same as a packaged wild-rice blend. Blends may contain several rice varieties, pre-seasoning or par-cooked grains; follow that package when it conflicts with this chart.
Formula and Worked Examples
Water volume = dry-rice volume × the variety-and-method water ratio. Ratios are based on volume, not rice weight.
Weight conversion: dry US cups = dry weight ÷ estimated grams per US cup for the selected variety. Rice-cooker cup conversion: US cups = 180 ÷ 236.6 × cooker cups. Cooked yield: dry US cups × estimated cooked-yield factor. Weight conversions use an estimated dry-rice density, so a kitchen scale plus package directions may produce a more brand-specific result.
Stovetop water examples (US cups)
| Dry rice | White long-grain 1:1.5 | Jasmine 1:1.25 | Basmati 1:1.5 | Brown 1:2 |
|---|---|---|---|---|
| 1 cup | 1.5 cups | 1.25 cups | 1.5 cups | 2 cups |
| 2 cups | 3 cups | 2.5 cups | 3 cups | 4 cups |
| 3 cups | 4.5 cups | 3.75 cups | 4.5 cups | 6 cups |
| 4 cups | 6 cups | 5 cups | 6 cups | 8 cups |
Example: 2 US cups of jasmine rice × 1.25 = 2.5 US cups of water. The calculator separately applies cautious texture and soaking adjustments and shows what changed.
How to Cook Rice Using the Calculator Result
- Measure and prepare. Measure the dry rice, then follow the selected variety's rinsing or soaking guidance and drain well.
- Add the calculated water. Use the calculator's water amount for the selected variety, method and texture. Ratios are rice:water by volume.
- Cook. Follow the generated stovetop, rice-cooker or electric pressure-cooker instructions and keep the lid closed.
- Rest and fluff. Rest for the displayed time, then fluff gently with a fork or rice paddle.
Methodology, Sources and Accuracy
Last reviewed: 16 July 2026. Prepared by the Starlight Tools editorial team. No named culinary reviewer is claimed for this page.
The chart and calculator provide practical starting points, not an exact or “perfect” ratio. The stovetop profiles were compared with variety charts from USA Rice and Utah State University Extension. Rice-cooker guidance is intentionally secondary to the appliance's supplied cup and fill lines. Pressure-cooker profiles were cross-checked against official Instant Pot examples and adjusted by variety; Instant Pot models and recipes differ, so the manual or a tested package recipe wins.
Dry cup weights are estimated density conversions (roughly 180–200 g per 236.6 ml cup, depending on variety), informed by USA Rice's approximate cup weight and not a laboratory measurement of your brand. Cooked-yield factors are estimates based on USDA Food Buying Guide and USA Rice yield tables. Times cover active cooking after a stovetop simmer begins or after an electric pressure cooker reaches pressure; warm-up time is not included.
Use package or appliance instructions first when they specify a different ratio, when cooking a seasoned mix, or when the cooker uses calibrated inner-pot lines. Pot diameter, batch size, lid fit, burner output, rice age, brand, rinsing and draining all change evaporation or absorption. Record what works with your usual rice and pot, then use the custom-ratio field next time.

Rice Troubleshooting: Rescue This Batch and Fix the Next
Mushy rice
Likely causes: too much water, excessive stirring or cooking too long. Rescue: uncover and spread the rice on a tray for a few minutes so steam can escape. Next batch: use 1–2 tablespoons less water per cup of dry rice, select firmer, and start checking earlier.
Sticky or gummy rice
Likely causes: loose surface starch, stirring, or fluffing too aggressively. Rescue: let it rest uncovered briefly, then lift and separate gently with a fork. Next batch: rinse until the water is less cloudy, drain well, and do not stir during absorption cooking. Do not rinse enriched rice if its package says not to.
Crunchy or hard rice
Likely causes: too little water, steam escaping, heat too low or insufficient cooking time. Rescue: sprinkle in 2–4 tablespoons hot water, cover tightly and cook on very low heat for 3–5 minutes, then rest. Next batch: check the lid fit and add 1–2 tablespoons water per cup.
Watery rice
Likely causes: the pot has not cooked long enough or the ratio is too high. Rescue: keep it covered over low heat for a few more minutes; if the grains are already tender, uncover briefly to evaporate the excess. Next batch: reduce water slightly or use a wider pot only if you can control evaporation consistently.
Burnt rice on the bottom
Likely causes: heat too high, a thin pot, a loose lid or not enough water. Rescue: remove the pot from heat without scraping the bottom and transfer the unburnt top layer to a clean bowl. Next batch: use the lowest stable simmer, a heavier pot, a tight lid and the full starting ratio.
Rice-to-Water Ratio FAQs
How much water do I need for 1, 2, 3 or 4 cups of white rice?
At the 1:1.5 stovetop starting ratio, use 1.5, 3, 4.5 or 6 US cups of water for 1, 2, 3 or 4 US cups of dry white rice. A rice cooker or Instant Pot usually uses less.
What is the white rice-to-water ratio?
Start with 1:1.5 rice:water by volume for stovetop white long-grain rice, 1:1.25 for a rice cooker, or 1:1 for an Instant Pot. Follow the package or appliance when it differs.
What is the jasmine rice-to-water ratio?
Start with 1:1.25 on the stovetop and 1:1 in a rice cooker or Instant Pot. Drain rinsed jasmine rice well so unmeasured rinse water does not soften it further.
What is the basmati rice-to-water ratio?
Start with 1:1.5 on the stovetop, 1:1.25 in a rice cooker, or 1:1 in an Instant Pot. Soaking can shorten cooking and may justify using slightly less water.
What is the brown rice-to-water ratio?
Start with 1:2 on the stovetop, 1:1.75 in a rice cooker, or 1:1.25 in an Instant Pot. Brown rice needs more time because its bran layer slows hydration.
What is the sushi rice-to-water ratio?
Start with 1:1.2 on the stovetop, 1:1.1 in a rice cooker, or 1:1 in an Instant Pot. Rinse thoroughly, drain well, and add sushi seasoning only after cooking.
What ratio should I use in a rice cooker?
Use the cooker's supplied 180 ml cup and matching inner-pot line whenever available. Without a line, this calculator's rice-cooker profiles are starting points because sealed cookers lose less steam than many stovetop pots.
What ratio should I use in an Instant Pot?
Many white varieties start at 1:1 rice:water by volume; brown, black and wild rice use more. Pressure time begins only after the pot reaches pressure, and natural-release time is separate.
Does water left from rinsing count?
Yes. Water clinging to poorly drained rice adds to the total, so rinse first, drain well, and then add the measured cooking water. This calculator assumes rinsed rice is well drained.
How does soaking change the ratio and cooking time?
Soaked and well-drained rice often cooks faster and may need a little less water. The calculator makes a cautious 0.05-cup-per-cup reduction and tells you to check early; package guidance takes priority.
Why do rice ratios differ by brand?
Grain cultivar, milling, age, pre-processing and the brand's tested method can change absorption. Pot geometry, lid fit and heat also change evaporation, so the package is the best first reference.
Can broth replace water?
Yes. Replace water with the same volume of broth, but account for its salt and any solids or fat. Thick sauces are not a direct one-for-one substitute, especially under pressure.
