1 six-inch sub (260 g) has about 530 calories.
Why estimates miss: Meatball Sub is a multi-ingredient dish. A footlong roughly doubles every number, so order the six-inch for a single serving. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
