California roll calories: estimates and calculator
The California roll is an uramaki with surimi (or crab), avocado, and cucumber, often with mayonnaise and sesame seeds or tobiko on the outside.
California roll in detail
The mix of rice, avocado, and mayonnaise makes the California roll higher in calories than a simple hosomaki. Avocado adds healthy fats but also calories.
Versions with generous mayo or tempura sit at the higher end of the range; leaner versions stay more modest.
A standard California roll is usually served in 8 pieces: for the whole-roll total, multiply the per-piece estimate by the actual number of pieces.
| Element | Estimate per piece |
| Classic California roll | 40–70 kcal |
| Whole roll (8 pieces) | 320–560 kcal |
| With extra mayo | +5–15 kcal per piece |
Portions vary: use the calculator for your version.
