How many carbs are in a slice of pizza?
A typical frozen cheese pizza serving (81g) has about 24g of carbohydrate and 22g of net carbs. Restaurant slices are often much larger and can run 30 to 40g of carbs each.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 serving, frozen cheese pizza (81g) | 23.5g | 1.8g | 21.7g |
| 100 grams | 29.0g | 2.2g | 26.8g |
Net carbs
One serving of cheese pizza has about 22g of net carbs, total carbs (24g) minus fiber (2g). Pizza crust is low in fiber. See the net carbs guide.
Glycemic index of a slice of pizza
The glycemic index of a slice of pizza is about 60. Pizza has a moderate glycemic index that varies with crust thickness and toppings. Thin-crust pizza tends to have a higher GI than thick crust because thin crust has less dough to slow digestion relative to the surface area.
For diabetes
A restaurant pizza slice from a large 14-inch pie typically weighs 100 to 130g and carries 30 to 40g of carbs. The fat from cheese slows gastric emptying and may delay the blood sugar rise by one to two hours after eating, which can make timing a bolus challenging. Deep dish and stuffed-crust varieties can exceed 50g of carbs per slice. Thin crust with vegetable toppings is the most manageable choice. See the diabetes carb-counting guide.
Keto and low carb
A standard pizza slice has 22 to 40g of net carbs depending on size. Pizza does not fit keto. Cauliflower-crust pizzas can reduce carbs to 10 to 15g per slice but are not zero.
Good to know
The USDA data here is for frozen cheese pizza, which tends to be smaller and more uniform than restaurant pizza. A standard restaurant slice of cheese pizza from a 14-inch pie weighs about 107g and has roughly 31g of carbs. New York-style pizza with a larger, thinner slice can range from 35 to 45g of carbs. Cauliflower-crust pizza typically has 10 to 15g of carbs per slice.

How many carbs are in a slice of pizza?
A frozen cheese pizza serving (81g) has about 24g of carbs. A typical restaurant cheese slice (107g) has about 31g of carbs.
Does thin-crust pizza have fewer carbs than thick crust?
Per slice, thin-crust can have fewer carbs because there is less dough. But restaurant slices vary widely in size and crust thickness.
Is pizza keto?
No. Even a small slice of regular pizza exceeds most keto daily carb budgets. Cauliflower-crust pizza reduces carbs but does not eliminate them.
How many carbs are in a whole pizza?
A 15-ounce frozen cheese pizza has about 130g of carbs in total. A restaurant 14-inch cheese pizza can have 200 to 250g of carbs across 8 slices.
Why does pizza sometimes spike blood sugar late?
The fat in cheese slows gastric emptying, which delays glucose absorption. Blood sugar can peak 2 to 4 hours after eating pizza rather than 1 to 2 hours as with bread.
