What this rice to water ratio calculator does
The right amount of water is the difference between fluffy, separate grains and a pot of paste or a pot of crunch. This free online rice to water ratio calculator gives you the exact water for any amount of rice or grain, for the way you actually cook it: stovetop, rice cooker, Instant Pot or pressure cooker, oven, microwave or boiled like pasta.
Choose the rice (white, jasmine, basmati, brown, sushi, wild, black and more, plus quinoa, couscous, bulgur, barley, millet, farro, steel-cut oats and buckwheat), set how much you are cooking in cups, grams, ounces, servings or cooked cups, and the tool returns the water in cups, millilitres and fluid ounces, the cook and rest times, the cooked yield, the number of servings, a pot size and a step-by-step method with a pot diagram. It also adjusts for texture, soaking, large batches and altitude.
How to use the calculator
- Pick the rice or grain and the cooking method. Methods that do not suit a grain are hidden.
- Set the amount. Measure dry rice in cups, grams or ounces, or enter the servings or cooked cups you want and the tool works out the dry rice for you.
- Choose a texture: firm and separate, standard or soft and tender.
- Add adjustments if they apply: altitude, soaked rice, salt and serving size.
- Read the result. You get the water, times, yield, pot size and the method, plus a table of the same grain in other cookers.
- Print, download a CSV or copy the plan.
Rice to water ratio chart
These are the standard-texture ratios the tool uses, written as rice : water by volume. Use the same cup for both, then adjust to taste.
| Rice or grain | Stovetop | Rice cooker | Instant Pot | Oven | Microwave |
|---|---|---|---|---|---|
| White rice, long-grain | 1 : 1.75 | 1 : 1.4 | 1 : 1.1 | 1 : 2 | 1 : 2 |

| Brown basmati rice | 1 : 2 | 1 : 2 | 1 : 1.25 | 1 : 2.25 | 1 : 2.25 |
| Sushi or short-grain white rice | 1 : 1.1 | 1 : 1.1 | 1 : 1 | 1 : 1.4 | 1 : 1.4 |

| Parboiled (converted) rice | 1 : 2 | 1 : 2 | 1 : 1.25 | 1 : 2.25 | 1 : 2.25 |
| Black (forbidden) rice | 1 : 2 | 1 : 2 | 1 : 1.25 | 1 : 2.25 | 1 : 2.25 |
| Red rice | 1 : 2 | 1 : 2 | 1 : 1.25 | 1 : 2.25 | 1 : 2.25 |
| Wild rice | 1 : 3 | 1 : 3 | 1 : 2 | 1 : 3 | 1 : 3 |
| Sticky (glutinous) rice, soaked | 1 : 1 | 1 : 1 | 1 : 0.9 | 1 : 1.1 | 1 : 1.1 |
| Quinoa | 1 : 2 | 1 : 2 | 1 : 1 | n/a | n/a |
| Couscous (instant) | 1 : 1.25 | n/a | n/a | n/a | n/a |
| Bulgur (medium or coarse) | 1 : 2 | n/a | 1 : 1.25 | n/a | n/a |
| Pearl barley | 1 : 2.5 | 1 : 2.5 | 1 : 2 | n/a | n/a |
| Millet | 1 : 2.25 | 1 : 2.25 | 1 : 1.5 | n/a | n/a |
| Farro (pearled) | 1 : 2.5 | 1 : 2.5 | 1 : 2 | n/a | n/a |
| Steel-cut oats | 1 : 3.5 | 1 : 3.5 | 1 : 3 | n/a | n/a |
| Buckwheat groats (kasha) | 1 : 2 | n/a | 1 : 1.25 | n/a | n/a |
Notice the pattern: the more water that can escape, the more you need to add. A pressure cooker needs the least, an open stovetop pot the most, and whole-grain rices need more than white rices because the bran absorbs water slowly.
Ratios by method: stovetop, rice cooker, Instant Pot, oven and microwave
Stovetop (absorption). The classic method. Use a heavy pot with a tight lid, bring to a boil, then turn the heat as low as it goes. White rice is usually 1 : 1.5 to 1 : 2, with jasmine at the lower end and parboiled rice at the higher end. Do not lift the lid.
Rice cooker. A cooker traps steam, so it needs less water, commonly 1 : 1.25 to 1 : 1.5 for white rice. The cooker switches to warm when the water is gone.
Instant Pot or pressure cooker. Almost no water escapes, so white rice needs about 1 : 1 and brown rice about 1 : 1.25. Use the natural release for 10 minutes so the grains finish steaming.
Oven baked. A good hands-off method for a big batch. Pour boiling water over the rice in a covered dish and bake at 375°F (190°C). Ratios are close to the stovetop.
Microwave. Use a bowl three times bigger than the water and rice, cover loosely, cook on high and then at medium power. The ratio is about 1 : 2 for white rice.
Boiled like pasta. Rice cooked in plenty of salted boiling water and drained will not go wrong on the water, but it loses some of the starch and flavour. It is useful for wild rice, black rice and cold rice salads.
How much rice per person
Dry rice roughly triples in volume when cooked, though brown, sushi and sticky rice expand a little less. The table is for white long-grain rice and a side-dish portion of about ¾ cup cooked.
| Dry rice | Cooked rice | Side-dish servings | Water (stovetop, standard) |
|---|---|---|---|
| ½ cup (92 g) | 1½ cups | 2 | 1 cup less 2 tbsp |
| 1 cup (185 g) | 3 cups | 4 | 1¾ cups |
| 1½ cups (278 g) | 4½ cups | 6 | 2⅝ cups |
| 2 cups (370 g) | 6 cups | 8 | 3½ cups |
| 3 cups (555 g) | 9 cups | 12 | 5¼ cups |
For a rice bowl or a main course, plan on ½ cup of dry rice per person. For a crowd, the oven method is the easiest, and the tool trims the stovetop ratio slightly for big batches because proportionally less water evaporates.
Cooking times for rice and grains
Times are for covered cooking after the water boils. The rest time matters: the grains finish absorbing water and the texture firms up.
| Rice or grain | Stovetop (cook + rest) | Instant Pot (pressure + natural release) | Dry grams per cup |
|---|---|---|---|
| White rice, long-grain | 15 + 10 min | 4 + 10 min | 185 g |
| Jasmine rice | 12 + 10 min | 3 + 10 min | 185 g |
| Basmati rice (white) | 12 + 10 min | 4 + 10 min | 180 g |
| Brown rice, long-grain | 40 + 10 min | 22 + 10 min | 190 g |
| Brown basmati rice | 35 + 10 min | 22 + 10 min | 185 g |
| Sushi or short-grain white rice | 15 + 10 min | 5 + 10 min | 200 g |
| Short-grain brown rice | 40 + 10 min | 24 + 10 min | 200 g |
| Parboiled (converted) rice | 20 + 5 min | 6 + 10 min | 190 g |
| Black (forbidden) rice | 35 + 10 min | 22 + 10 min | 190 g |
| Red rice | 35 + 10 min | 20 + 10 min | 190 g |
| Wild rice | 50 + 10 min | 25 + 10 min | 160 g |
| Sticky (glutinous) rice, soaked | 20 + 10 min | 8 + 10 min | 200 g |
| Quinoa | 15 + 5 min | 1 + 10 min | 170 g |
| Couscous (instant) | 0 + 5 min | n/a | 170 g |
| Bulgur (medium or coarse) | 14 + 10 min | 5 + 10 min | 140 g |
| Pearl barley | 40 + 10 min | 20 + 10 min | 200 g |
| Millet | 18 + 10 min | 10 + 10 min | 200 g |
| Farro (pearled) | 30 + 5 min | 12 + 10 min | 190 g |
| Steel-cut oats | 25 + 5 min | 10 + 10 min | 160 g |
| Buckwheat groats (kasha) | 13 + 5 min | 3 + 10 min | 170 g |
Rinsing and soaking rice
Rinse rice in a sieve under cold running water, swishing with your hand, until the water runs mostly clear. This washes away surface starch, so the grains cook separately. Rinsing is recommended for jasmine, basmati, long-grain, sushi and brown rice, and unnecessary for parboiled and many enriched rices. Drain well so that you do not add extra water to the pot.
Soaking basmati for 30 minutes makes the grains cook evenly and stretch longer; the tool trims the ratio by 0.15 when you choose it. Brown rice can be soaked for an hour or more to shorten the cooking time. Sticky rice must be soaked for several hours, and is steamed or cooked with very little water.
Altitude, pots and other things that change the ratio
At altitude, water boils at a lower temperature, so rice cooks more slowly and needs more water. A good rule of thumb is to add about 5% more water for 3,000 to 5,000 feet, 10% for 5,000 to 8,000 feet and 15% above that, with a little more time. The calculator applies these automatically.
The pot also matters. A wide, thin-bottomed pot loses water and scorches; a heavy pot with a snug lid keeps the steam in. If your lid is loose, put a piece of foil under it. A pot that is too small will boil over; the tool shows a minimum pot size in quarts.
Rice to water ratio by weight (grams)
Cooks who like precision measure rice and water by weight. One millilitre of water weighs one gram, so the ratio in grams is easy: 185 g of white rice (about 1 cup) with 310 to 370 ml of water. The calculator shows both the volume ratio and the grams of water per gram of rice, which is handy for a rice cooker or a scale.
Troubleshooting: mushy, hard, sticky or burnt rice
- Mushy: too much water or too much stirring. Use the firm texture and keep the lid on.
- Hard or crunchy: too little water, too hot a simmer or too short a cook. Add 2 to 4 tablespoons of water, cover and steam over very low heat for 5 minutes.
- Gummy: starch was not rinsed off, or the rice sat too long in water.
- Burnt on the bottom: the heat was too high, or the pot was too thin. Lower the heat and use a heavy pot.
- Wet on top, hard at the bottom: too much water for the method, or the rice was not stirred before the lid went on.
Ratios for quinoa, couscous, bulgur, barley and other grains
The grain list in the tool covers the common ones. As a quick guide, quinoa is 1 : 2 and takes about 15 minutes, couscous is about 1 : 1¼ and needs only a 5 minute soak in hot liquid, bulgur is about 1 : 2 and takes 14 minutes, pearl barley is 1 : 2½ and takes about 40 minutes, millet is 1 : 2¼, farro is 1 : 2½, steel-cut oats are 1 : 3½, and buckwheat groats are 1 : 2 for about 13 minutes. Rinse quinoa to remove its bitter coating.
Storing and reheating cooked rice safely
Uncooked rice can contain spores of a bacterium that survives cooking. If cooked rice stands at room temperature for hours the spores can grow and produce toxins that reheating does not destroy. Cool leftover rice quickly (spread it in a shallow container), put it in the refrigerator within an hour or two, eat it within 3 to 4 days, and reheat it until it is steaming hot all the way through. Never reheat rice more than once.
Worked examples
Four people, a side of white rice. Four side servings is 3 cups cooked, so 1 cup of dry long-grain rice. The tool gives 1¾ cups of water for the stovetop, 15 minutes of simmering and 10 minutes of rest.
Basmati for a curry for six. Choose servings, enter 6 and a standard serving size, and the tool works out about 1½ cups of dry basmati. Soak it for 30 minutes and the water drops to about 2 cups.
Brown rice in an Instant Pot. 2 cups of brown rice with 2½ cups of water, 22 minutes on high pressure and a 10 minute natural release.
Rice at 6,000 feet. A cup of white rice at that altitude needs about 10% more water and 15% more time than at sea level.

Frequently asked questions
What is the rice to water ratio for white rice?
For long-grain white rice on the stovetop, use about 1 cup of rice to 1½ to 2 cups of water (1 : 1.5 to 1 : 2). This calculator defaults to 1 : 1.75 for a standard texture, and lets you choose firm or soft.
What is the ratio for jasmine rice?
Jasmine rice needs a little less water than regular long-grain rice, about 1 cup of rice to 1¼ to 1½ cups of water on the stovetop and about 1 : 1 in an Instant Pot.
What is the ratio for basmati rice?
Use about 1 cup of basmati rice to 1½ cups of water on the stovetop after rinsing, or 1¼ cups if you soak it for 30 minutes. In an Instant Pot, 1 : 1 works well.
What is the ratio for brown rice?
Brown rice keeps its bran, so it needs more water and more time: about 1 cup of rice to 2 to 2¼ cups of water on the stovetop for 40 minutes, or 1 : 1.25 under pressure for 22 minutes.
How much water for 2 cups of rice?
For 2 cups of long-grain white rice use about 3½ cups of water on the stovetop, or about 2½ cups in a rice cooker. Enter 2 cups in the calculator and choose your method to see the exact figure.
What is the rice to water ratio in a rice cooker?
Most rice cookers work best at about 1 : 1.25 to 1 : 1.5 for white rice, because little steam escapes. Many cookers print water lines inside the pot; use those as a cross-check.
What is the rice to water ratio for an Instant Pot?
In a pressure cooker almost no water evaporates, so white rice usually needs only about 1 : 1 to 1 : 1.1 and brown rice about 1 : 1.25. Cook white rice for about 4 minutes on high pressure and brown rice for about 22 minutes, with a 10 minute natural release.
Do I need to rinse rice?
Rinsing removes surface starch and gives separate, fluffy grains, so it is recommended for most long-grain, jasmine and basmati rice. Sushi rice is rinsed until clear. Parboiled rice and enriched rice are often not rinsed.
Should I soak rice before cooking?
Soaking for 30 minutes helps basmati and brown rice cook evenly and reduces the water a little. Sticky (glutinous) rice should be soaked for several hours. Soaking is optional for other rice.
How much rice per person?
Plan about ¼ to ⅓ cup of dry rice per person as a side dish (about ¾ cup cooked) and ½ cup dry per person for a main course bowl. One cup of dry white rice makes about 3 cups cooked.
Why is my rice mushy?
Mushy rice usually has too much water, was stirred while cooking (which releases starch), or was not rinsed. Use a firmer texture setting, avoid lifting the lid and let the rice rest, covered, off the heat.
Why is my rice hard or crunchy?
Hard rice usually did not get enough water or steam. Add 2 to 4 tablespoons of water, cover tightly and steam for another 5 minutes over very low heat. At high altitude, add more water and time.
Why does the ratio change by method?
Water leaves a pot by evaporation. A heavy pot with a tight lid loses a little, an open pot loses more, and a pressure cooker loses almost none. Rice cookers and pressure cookers therefore need less water than a stovetop pot.
Does altitude change the ratio?
Yes. Water boils at a lower temperature at altitude, so rice needs more water and more time. This calculator adds about 5 to 15% more water and up to 25% more time as you go above 3,000 feet.
Can I use broth instead of water?
Yes. Use the same ratio with stock or broth for more flavour, and reduce the added salt because many broths are salty.
How long can I keep cooked rice?
Cool it quickly, ideally within an hour, and refrigerate it in a shallow container. Eat it within 3 to 4 days and reheat until steaming hot. Do not leave cooked rice at room temperature for long.
Does this work for quinoa, couscous, barley and other grains?
Yes. The grain list includes quinoa, couscous, bulgur, pearl barley, millet, farro, steel-cut oats and buckwheat, each with its own ratio and time.
Can I print or save the result?
Yes. Print / save as PDF prints only the plan, the pot diagram and the method; CSV downloads the figures and copy summary puts them on your clipboard. Nothing is uploaded.
