Rice Calculator

Rice cooking is a precise science where the ratio of water to rice determines the final texture. Too little water produces hard, crunchy grains. Too much water creates mushy, porridge-like results. The correct ratio depends on the rice variety, as each type has different starch content, grain length, and absorption characteristics. The calculator handles nine common rice types with their specific water ratios, cooking times, and resting periods.

Long-grain white rice (the most common variety in the US) uses a 1:1.75 ratio — 1.75 cups of water for each cup of rice. It produces fluffy, separate grains. Jasmine and basmati rice use slightly less water at 1:1.5 because their aromatic varieties have thinner husks that absorb water more efficiently. Short-grain and sushi rice use even less water (1:1.25 and 1:1.2 respectively) because their higher amylopectin starch content creates the sticky, clumped texture desired for sushi and risotto.

Brown rice requires significantly more water (1:2.5) and much longer cooking time (45 minutes vs. 18 minutes) because the intact bran layer acts as a barrier to water absorption. Wild rice needs the most water (1:3) and the longest cooking time (50 minutes). Arborio rice for risotto uses the highest ratio (1:4) but releases starch during cooking to create the characteristic creamy sauce.

The cooking method affects timing but not the water ratio. Different methods deliver heat differently, which changes how long the rice needs to absorb water and gelatinize its starches:

• Stovetop: Standard method with timed cooking and resting. The most control over the process.
• Rice cooker: Automatic and hands-off. Cooking time is slightly longer (1.1×) because the cooker cycles between heating and steaming.
• Instant Pot/Pressure cooker: Dramatically faster cooking (0.5× time) because pressure raises the boiling point. Some prefer this for brown rice.
• Oven: Even heat distribution but longer cooking (1.5×). Good for large batches where stovetop space is limited.
• Microwave: Quick (0.8× time) but can produce uneven results. Use a microwave-safe container with a vented lid.

Calculate perfect rice in four steps:

1. Enter number of servings: Input how many people you are serving.
2. Choose rice type: Select from nine common varieties including long grain, basmati, jasmine, brown, wild, sushi, and arborio.
3. Select serving size: Choose side dish or main course. Main course portions are 1.5× larger.
4. Choose cooking method: Select stovetop, rice cooker, Instant Pot, oven, or microwave.
5. Review results: View dry rice amount (cups and grams), water amount (cups and ml), salt, cooking time, rest time, total time, and nutritional estimates.

Rinse your rice under cold water until the water runs clear. This removes excess surface starch that causes rice to become gummy and sticky. Place the rice in a fine-mesh strainer and rinse for 30-60 seconds, agitating gently with your hand. This step is especially important for long-grain and basmati rice where separate, fluffy grains are desired.

Use a tight-fitting lid and do not lift it during cooking. Every time you remove the lid, steam escapes and the cooking time increases. Once the water reaches a boil, reduce to the lowest heat setting that maintains a gentle simmer. The steam trapped under the lid does the actual cooking.

Rest the rice after cooking with the lid still on. During resting, the remaining steam redistributes moisture evenly through the grains, and any water that collected on the bottom absorbs upward. Fluff with a fork, not a spoon — the tines separate the grains without crushing them.
