Why rice ratios are a starting point, not a rule
"One cup of rice, two cups of water" is a decent default for long-grain white rice and a disaster for sushi rice, which wants barely more water than it weighs. The reason is the grain: long-grain varieties absorb more liquid and stay separate, short-grain varieties are starchier and sticky, and wholegrain rice keeps its bran layer, which slows water uptake and needs both more water and more time. Cooking method adds a second variable, because a rice cooker holds steam in while a stovetop pan loses it.
Ratios by type and method
| Rice | Stovetop | Rice cooker | Microwave | Time |
|---|---|---|---|---|
| Long-grain white | 1 : 1¾ | 1 : 1½ | 1 : 2 | 15–18 min |
| Jasmine | 1 : 1½ | 1 : 1.4 | 1 : 2 | 12–15 min |
| Basmati | 1 : 1½ | 1 : 1.4 | 1 : 2 | 10–12 min |
| Short-grain / sushi | 1 : 1.1 | 1 : 1.1 | 1 : 1.5 | 12–15 min |
| Brown | 1 : 2¼ | 1 : 2 | 1 : 2.5 | 35–45 min |
| Wild | 1 : 3 | 1 : 3 | 1 : 3.5 | 45–55 min |
| Glutinous / sticky | 1 : 1 | 1 : 1 | 1 : 1.2 | 20–25 min |
These are volumes, not weights: one cup of dry long-grain rice weighs about 185 g, a cup of sushi rice about 200 g, and a cup of wild rice only about 160 g. That is why the same "one cup" instruction produces different pots of rice depending on the bag you opened — the calculator converts between the two so you can weigh instead.
The finger method, quantified
The traditional check is to level the rice, touch its surface with your fingertip and add water until it reaches the first joint — roughly 2 cm. That works because the ratio of water depth to rice depth stays about the same across pot sizes, but it is only reliable with a finger of average length. Entering your pot diameter here converts the water volume into an actual depth, so you can measure once with a ruler instead of guessing every time.
Getting it right in practice
- Rinse first. Three or four changes of water until it is mostly clear removes surface starch; skipping it makes jasmine and sushi rice gluey.
- Weigh rather than scoop if you want repeatability: 75 g of dry rice per person is a generous side, 60 g a smaller one.
- Do not lift the lid. Every time you peek you lose steam, which is exactly the water the grain needed.
- Rest, then fluff. Ten minutes off the heat lets the moisture even out; fluffing with a paddle rather than a spoon keeps the grains intact.
- Adjust for your own pot. A wide pan evaporates more than a narrow one. Note how your last batch turned out and nudge the ratio by 0.1 next time.
Frequently asked questions
What is the correct rice to water ratio?
For long-grain white rice, 1 : 1¾ by volume; jasmine and basmati 1 : 1½; short-grain or sushi rice 1 : 1.1; brown rice 1 : 2¼; wild rice 1 : 3; glutinous rice 1 : 1. A rice cooker needs slightly less water than a stovetop pan because it traps steam.
Why is my rice mushy or crunchy?
Almost always the ratio or the pot. Too much water (or lifting the lid and losing steam) makes it mushy; too little, or cooking at too high a heat so the water boils off early, leaves the centre crunchy. Weighing the rice and matching the ratio to the variety fixes most of it.
How much dry rice per person?
About 75 g (roughly ½ cup) of dry rice per person as a side dish, or 100 g for a main-course portion. Rice roughly doubles to triples in weight, so 75 g dry becomes about 200 g cooked.
Do I need to soak rice before cooking?
Basmati benefits from 20–30 minutes, sushi rice from about 30 minutes, and glutinous rice needs 4–6 hours or overnight. Long-grain white, jasmine, brown and wild rice do not need soaking; if you do soak, reduce the water by 5–10%.
How much water does brown rice need?
About 1 : 2¼ by volume on the stovetop and 1 : 2 in a rice cooker, with 35–45 minutes of cooking. The bran layer slows water absorption, which is why brown rice needs both more liquid and roughly double the time of white rice.
What is the finger method for measuring rice water?
Level the rice, rest your fingertip on its surface and add water until it reaches the first joint of your index finger — about 1.5–2 cm above the rice. It is a handy field method, but a ruler plus your pot diameter gives a repeatable answer.
How much cooked rice does 1 cup of dry rice make?
Roughly 3 cups for long-grain white rice, 2½–3 cups for jasmine and basmati, 2 cups for brown and glutinous rice, and up to 3½ cups for wild rice. The calculator shows the predicted cooked weight for your exact portion.
Should I add salt or oil to the water?
Salt is optional and best added at about ½ teaspoon per cup of dry rice; oil or butter (a teaspoon per cup) keeps grains separate and helps against sticking. Acidic additions such as vinegar or tomato change the texture, so add them after cooking for sushi rice.
