The key to perfect rice is the right water ratio. Our calculator gives you exact measurements for any rice type and cooking method, so you never have mushy or crunchy rice again.
Different rice types absorb different amounts of water. Long-grain white rice typically uses a 1:1.5 ratio, while brown rice needs 1:2.5. The cooking method also affects how much water you need. Water needs rise with whole-grain varieties because the intact bran layer slows absorption; standard cooking directions, such as those from the USA Rice Federation, give higher water ratios and longer times for brown and wild rice than for white.
Basic Rice Formula
A home cook finds the exact water amount for two cups of white rice cooked on the stovetop
Someone scales up the water ratio for brown rice, which needs more liquid and longer cooking time
A user converts cups of rice into the right water level for a large rice cooker meal
A meal prepper measures water for six servings of rice without ending up with mushy or dry grains
Too much water = mushy. Too little = hard, undercooked grains.
Each variety has unique starch content and absorption rates.
Rice cookers and Instant Pots need slightly less water than stovetop.
Yes, for most rice types. Rinsing removes excess starch for fluffier results. Rinse until water runs clear (usually 2-3 times). Exception: arborio for risotto - don't rinse, you want the starch.
Resting allows steam to finish cooking and moisture to distribute evenly. 5-10 minutes covered makes a big difference in texture.
Common causes: heat too high, not enough water, or lifting the lid during cooking. Try reducing heat once it boils, and don't peek!
Yes. White long-grain rice uses about 1:1.5 rice-to-water, while brown rice needs roughly 1:2.25–2.5 and 40–45 minutes to cook, because the intact bran layer absorbs water more slowly. This calculator adjusts the ratio by rice type.
