Wondering how many carbs are in your sushi? This calculator estimates the carbohydrate content per 100 grams for a wide range of sushi types, from simple salmon nigiri to elaborate dragon rolls. Whether you're tracking macros, managing blood sugar, or following a low-carb diet, knowing the carb density of your favorite sushi helps you make informed choices.
Simply select the sushi type, choose your preferred unit (grams or ounces), and optionally enter a serving size to get the total carbs. The tool also breaks down net carbs (subtracting fiber) and provides a quick reference for common sushi pieces. Perfect for nutrition enthusiasts, diabetics, and anyone counting carbs at their favorite sushi spot.

How to Use This Tool
Select the sushi type from the dropdown, enter the amount you plan to eat (in grams or ounces), and click Calculate Carbs. The tool instantly shows total carbohydrates, fiber, and net carbs for that serving. Use the quick-fill buttons to set common portion sizes (50 g, 100 g, 150 g, 200 g) without typing.
For example, if you're having a California roll and want to know the carbs in a typical 6-piece serving (about 150 g), select California Roll, enter 150, and the calculator will show roughly 45 g of total carbs and about 43.5 g net carbs. This makes it easy to compare different sushi options side by side.
How Carb Values Are Estimated
The carb values used here are based on average nutrition data from major food databases and sushi restaurant nutrition guides. Because sushi is a combination of vinegared rice, fish, vegetables, and sometimes sauces, the exact carb content can vary by recipe and portion size. The values represent typical restaurant-style sushi without added sauces or extra toppings.
For nigiri, the rice portion is the main carb source, while maki and rolls include additional rice and sometimes sweetened ingredients like crab salad or tempura. Inari sushi, which uses sweetened tofu pouches, tends to be higher in carbs. The fiber values are generally low because white rice is the primary ingredient, but rolls with vegetables or avocado add a bit more.
Worked Examples
Example 1: You eat 120 g of salmon nigiri (about 6 pieces). Total carbs = (21 g/100g) × 120 g = 25.2 g. Net carbs = 25.2 − (0.5 × 1.2) = 24.6 g.
Example 2: A dragon roll serving of 200 g. Total carbs = (32 g/100g) × 200 g = 64 g. Fiber = 1.5 × 2 = 3 g, so net carbs = 61 g.
Example 3: You have 85 g of cucumber maki. Total carbs = (28 g/100g) × 85 g = 23.8 g. Net carbs = 23.8 − (1.2 × 0.85) = 22.8 g.
Tips for Lower-Carb Sushi Choices
- Choose sashimi (no rice) for nearly zero carbs.
- Opt for rolls with cucumber or avocado instead of extra rice.
- Ask for "light rice" or "no rice" at the restaurant.
- Limit sweet sauces like eel sauce or spicy mayo, which add sugar and carbs.
- Use this calculator to plan your sushi meal within your daily carb budget.
Factors Affecting Accuracy
The actual carb content can differ based on the amount of rice used, the type of vinegar (some contain sugar), and whether the sushi includes sweetened ingredients like imitation crab or tamago. Restaurant portions vary widely, so weighing your sushi is the most accurate method. For packaged sushi, check the nutrition label for the most precise values.
Frequently Asked Questions
Is sushi high in carbs? Yes, most sushi is carb-heavy because of the rice. A typical 6-piece roll can contain 30–50 g of carbs. However, sashimi and cucumber rolls are much lower.
What is net carbs? Net carbs are total carbs minus fiber. Since fiber isn't digested, many low-carb dieters track net carbs. Sushi has little fiber, so net carbs are close to total carbs.
Can I eat sushi on a keto diet? Traditional sushi is usually too high in carbs for keto, but you can enjoy sashimi or make "keto sushi" with cauliflower rice.
How many carbs in a California roll? A typical California roll (about 150 g) has around 45 g of total carbs. This calculator gives you a precise estimate based on your serving size.
