Why does the water ratio differ by rice variety?

Each variety has a different grain structure, starch content, and density. Brown rice retains its outer bran layer, which absorbs more water and takes longer to cook. Long-grain varieties like basmati release less starch and stay separate, while short-grain sushi rice is stickier and needs slightly less water to reach the right texture.

Should I rinse the rice before cooking?

Rinsing removes excess surface starch, which reduces stickiness and clumping. For jasmine and basmati it is recommended. For sushi rice, a light rinse (2–3 times) is standard. If you rinse your rice, drain it thoroughly before using the ratios from this calculator — the ratios assume dry, uncooked rice.

Why use less water in a rice cooker?

A rice cooker traps steam more efficiently than an open stovetop pot, so less water evaporates. Using stovetop ratios in a rice cooker often results in wet, mushy rice. Most rice cooker manufacturers recommend reducing water by about 10–15%.

Why use even less water in an Instant Pot?

The Instant Pot is a sealed pressure cooker. Virtually no steam escapes during cooking, so only a minimal amount of water is needed beyond what the rice absorbs. Using standard stovetop ratios will produce very soggy rice in a pressure cooker.

How much does rice expand when cooked?

White rice roughly doubles in volume when cooked (1 cup dry yields about 2–3 cups cooked depending on variety). Brown rice expands by about 2 to 2.5 times. This calculator shows the estimated cooked yield so you can plan portions accurately.

Can I use these ratios for wild rice or rice blends?

Wild rice and blended mixes (e.g., white + wild) have their own ratios, typically around 1:3. This tool covers the five most common pure varieties. Always check the package instructions for specialty blends as ratios can vary by brand.
