On average, one standard sushi roll requires about 1/4 cup (approx. 75g) of uncooked sushi rice. This yields enough cooked, seasoned rice to fill and roll one nori sheet comfortably.
The classic ratio is roughly 1 tablespoon of rice vinegar per 1/4 cup of uncooked rice. This calculator uses a well-established 4:1 rice-to-vinegar ratio to ensure the right balance of tang and stickiness.
For every 1/4 cup of uncooked rice, use about 1/2 teaspoon of sugar and 1/4 teaspoon of salt. The combination with rice vinegar gives sushi rice its signature sweet, savory, and slightly tangy flavor.
Short grain Japanese or medium grain rice is strongly recommended for sushi. These varieties have higher starch content, making the rice sticky enough to hold rolls together. Long-grain rice doesn't clump well and will cause your rolls to fall apart.
Use a 1:1.2 ratio of rice to water — for every cup of uncooked rice, use 1.2 cups of water. This produces rice that is cooked through but firm enough to handle and season without becoming mushy.
Season the rice immediately after cooking while it's still hot. Add the vinegar mixture and fold it in gently using a rice paddle or flat spatula. Fan the rice as you mix to cool it quickly and achieve a glossy finish.
Sushi rice is best used within 1–2 hours of preparation at room temperature. Refrigerating it causes the rice to harden and lose its sticky texture. If you must store it, wrap it tightly and let it return to room temperature before using.
One cup of uncooked sushi rice typically makes about 4 standard sushi rolls. The rice roughly doubles in volume when cooked, yielding enough for 4 nori rolls when combined with fillings.
