Rice to Water Ratio Changes With Every Grain, So Stop Using 2 to 1
The 2 to 1 rule only suits white long grain. Here's the rice to water ratio for 12 kinds of rice, the same chart in grams, what changes in a rice cooker, and what a serving costs at $1.12 a pound.
Two cups of water for every cup of rice works for exactly one kind of rice: plain white long grain. Basmati wants 1.5 cups, short grain wants 1.25, and parboiled rice drinks 2.25. If your rice keeps coming out gluey or crunchy, the rice to water ratio you learned is probably the culprit, not your stove.
The fix is a short chart and, if you own one, a kitchen scale. A cup of uncooked rice weighs about 180 grams, which means you can turn every rice to water ratio below into grams and stop guessing how full your cup really is.
The rice to water ratio chart for 12 kinds of rice
These volume ratios come from the Gigacalculator rice to water chart, and they line up with what most package directions say. Times are for a covered pot on the stovetop, measured once the water returns to a simmer.
| Rice type | Water per cup | Cook time |
|---|---|---|
| White long grain | 2 cups | 18 to 20 min |
| White short grain | 1.25 cups | 15 min |
| Jasmine | 1.75 cups | 15 to 20 min |
| Basmati | 1.5 cups | 15 to 20 min |
| Sushi (Calrose) | 1.33 cups | 18 to 20 min |
| Brown long grain | 1.75 cups | 40 to 45 min |
| Brown short or medium | 2 cups | 50 min |
| Parboiled (converted) | 2.25 cups | 20 min |
The same chart puts white medium grain at 1.5 cups for 15 minutes, Texmati at 1.75 cups, and both black japonica and wild rice at 2 cups, with 45 to 50 minutes for wild rice and 50 for black japonica. Notice the spread: the thirstiest rice on the list takes almost twice the water of the least thirsty one.
Why weighing gets the proportion of water to rice right
Cups are where most rice goes wrong. Scoop straight from the bag and you pack the grains in; spoon them in and you get less. A scale doesn't care how you filled it, and water is the easiest ingredient on earth to weigh because a milliliter of it weighs a gram.
What 1 cup of rice in grams really means
The food blog Foodess puts 1 cup of rice in grams at about 180 for uncooked rice, and a US cup of water is about 237 grams. Our guide to grams and ml explains why water is the one liquid where those two numbers match.
Turning the chart into a weight ratio
Divide the water weight by 180 grams of rice and the proportion of water to rice by weight falls out. White long grain lands near 2.6 to 1 by weight, while basmati sits close to 2 to 1. So the famous 2 to 1 rule is actually right for basmati if you weigh, and wrong for long grain if you don't.
Quick rule for a scale: long grain white rice takes about 2.6 grams of water per gram of rice, and basmati takes about 2 grams.
Basmati rice to water ratio and the other aromatic grains
The basmati rice to water ratio is 1.5 cups of water per cup of rice, a quarter cup less than jasmine. That difference matters because basmati grains are long and slender and turn mushy fast when they sit in extra water.
Jasmine sits in between
Jasmine takes 1.75 cups and cooks in 15 to 20 minutes, the same window as basmati. If you swap one for the other in a recipe, change the water too, or you'll be off by about 59 grams per cup of rice.
Swapping jasmine for basmati without changing the water adds about a quarter cup per cup of rice, which is enough to turn fluffy into sticky.
The rice cooker ratio is not the stovetop ratio
A rice cooker is a sealed box, so it loses less steam than a pot with a rattling lid. That's why the rice cooker ratio in your machine's manual can differ from the chart above, and why the lines inside the bowl usually beat any cup you bring from the drawer.
Many machines also come with their own measuring cup, and it isn't necessarily a full US cup. If you fill the bowl with the machine's cup and then add water with a kitchen measuring cup, your rice and water ratio in the rice cooker is off before you press start.
Uncooked rice to cooked rice, in weight and calories
Going from uncooked rice to cooked rice, the volume roughly triples, so 1 cup of dry rice gives about 3 cups cooked, according to Foodess. USDA data shown on ReciPal puts a cup of cooked long grain white rice at 158 grams and 205 calories.
| Amount | Weight | Calories |
|---|---|---|
| 1 cup cooked | 158 g | 205 |
| 1/2 cup cooked | 79 g | about 103 |
| 100 g cooked | 100 g | about 130 |
| 3 cups cooked (1 cup dry) | about 474 g | about 615 |
Cooked rice calories per gram
Cooked rice calories work out to about 1.3 per gram for long grain white rice, with 45 grams of carbs and 4 grams of protein in that 158 gram cup. Weigh your cooked portion and multiply by 1.3; it's faster than trying to level a heaped cup of sticky rice.
What counts as one serving
Montana State University Extension, following MyPlate guidance, counts half a cup of cooked rice as one ounce equivalent of grains, the same logic behind our oatmeal serving guide. Adults need roughly 5 to 10 of those a day, so a full cup of cooked rice covers two.
One cup of dry rice turns into about three cups cooked and roughly 615 calories, which is why a single rice cooker batch can feed a family.
What getting the ratio right saves you at $1.12 a pound
Rice is cheap, which is exactly why people shrug off a ruined pot. White long grain averaged $1.12 a pound in September 2026, up from $1.05 for 2025, according to BLS figures compiled by Officialdata.org. A pound is about 454 grams; run your own bag sizes through the grams to ounces converter.
At that price a 45 gram side portion costs about 11 cents and a 90 gram main portion about 22 cents. A cup of dry rice is roughly 44 cents. Toss one scorched batch a week and you've binned about $23 of rice in a year, plus whatever you were serving it with.
Rice to water ratio questions people ask
How much water do I need for 2 cups of rice?
Double the chart. Two cups of white long grain take 4 cups of water, about 946 grams, while 2 cups of basmati take 3 cups, about 710 grams. By weight, that's 360 grams of rice either way.
How many calories are in 1 cup of rice?
It depends on whether the cup is cooked. Counting 1 cup of rice calories after cooking, long grain white rice comes to 205. A cup of dry rice becomes about three cooked cups, so it carries roughly 615 calories once it's on the table.
Does brown rice need more water than white?
Not always. Brown long grain takes 1.75 cups, which is actually less than white long grain at 2 cups, but it needs 40 to 45 minutes. Brown short and medium grain take 2 cups and about 50 minutes.
Is the water ratio for rice cooker rice different?
It can be, since the sealed lid traps steam. Follow the lines in the cooker bowl with the machine's own cup, or weigh rice and water and keep notes on what your cooker likes. If your scale reads oddly, our nickel calibration trick checks it in two minutes.
