Calories in a 13-Inch Pizza
A whole 13-inch cheese pizza has roughly 1,900-2,300 calories, which works out to about 240-290 calories per slice when cut into 8. Pepperoni and other cured-meat toppings push each slice 30-60 calories higher, while thin-crust versions with lighter cheese sit below the range. Crust thickness, cheese quantity and toppings drive most of the variation between pizzerias.

Still Wondering About SlimAI
A 13-inch pizza is usually cut into 8 slices, though some pizzerias cut large pies into 10. At 8 slices, each one is about 100 g and roughly 240-290 calories for a standard cheese pizza.
A cheese slice from a 13-inch pizza runs about 240-290 calories, while a pepperoni slice adds roughly 30-60 more, landing around 280-340. The cured meat contributes extra fat and sodium on top of the cheese base.
Yes — pizza can fit a calorie-deficit routine when it is portioned. Two cheese slices at about 530 calories plus a side salad is a workable meal; the difficulty is that a whole 13-inch pizza carries around 2,000 calories, close to many people's full daily budget.
Point SlimAI's camera at your pizza and the photo scan estimates the slices and toppings, or search "cheese pizza" and log by slice count or grams. Voice logging works too: "two slices of pepperoni pizza".
