Yes, pizza crust has fiber, and the honest number is lower than most pizza articles claim. In USDA’s national food composition data, one large slice of cheese pizza on a regular restaurant crust carries about 2.7 grams of fiber, a thin slice about 2.0 grams, and a whole wheat crust slice 4.2 to 5.1 grams. That’s the whole slice, crust plus sauce plus cheese, not the crust standing alone.
You know the drill on pizza night. Nobody’s eating a salad, the box is open, and the only thing you control is what’s under the cheese. The FDA’s Daily Value for fiber is 28 grams, so a regular slice is about 10 percent of a day, and NIH’s MedlinePlus notes that Americans average about 16 grams a day against a 21 to 38 gram recommendation. Pizza isn’t where you win that. It’s where you stop losing ground.
For the rest of the cart, our guide to eating more fiber on a budget covers the foods that don’t come under cheese.
How much fiber is in a slice of pizza, by crust type
| Crust (cheese pizza) | Fiber per 100 g | USDA slice weight | Fiber per slice | Share of 28 g DV |
|---|---|---|---|---|
| Stuffed crust | 1.7 g | 148 g | 2.5 g | 9% |
| Restaurant thin crust | 2.3 g | 86 g | 2.0 g | 7% |
| Restaurant regular (medium) crust | 2.3 g | 119 g | 2.7 g | 10% |
| Restaurant thick crust | 2.2 g | 132 g | 2.9 g | 10% |
| Frozen thin crust | 3.0 g | 97 g | 2.9 g | 10% |
| Gluten-free thin crust | 2.5 g | 119 g | 3.0 g | 11% |
| Whole wheat thin crust | 3.5 g | 119 g | 4.2 g | 15% |
| Whole wheat thick crust | 3.9 g | 132 g | 5.1 g | 18% |
Every row is a cheese pizza, so the crust is the only thing changing. Fiber per 100 grams and the slice weights both come from the FNDDS 2021-2023 release of USDA FoodData Central (records 2708618, 2708615, 2708616, 2708617, 2708612, 2708693, 2708687 and 2708688, searchable by ID at FoodData Central), checked 2026-07-30. Fiber per slice is the USDA value times USDA’s own gram weight for one piece.
Two footnotes. Seven rows use USDA’s “1 piece, large pizza” measure; frozen thin crust is the exception, since record 2708612 publishes no large-pizza piece, so its 97 grams is the “1 piece, NFS” weight. And that isn’t the full FNDDS list: USDA also has gluten-free thick crust at 2.9 grams per 100 grams (record 2708694) and frozen thick crust at 2.2 (record 2708613). All national survey averages, not your local pizzeria.
How much fiber is in the crust alone, with nothing on top
Everything above is a finished slice. For the bare crust, USDA files the numbers somewhere else: FoodData Central’s Branded Foods dataset, which carries label data manufacturers submit themselves.
| Crust (bare, nothing on top) | Fiber per 100 g | Label serving | Fiber per serving |
|---|---|---|---|
| Angelic Bakehouse Thin & Crispy 7 Sprouted Whole Grain | 10 g | 50 g (1/4 crust) | 5.0 g |
| 365 Whole Foods Market organic whole wheat thin crust | 6.4 g | 47 g (1/3 crust) | 3.0 g |
| Banza chickpea crust | 6.2 g | 48 g (1/4 crust) | 3.0 g |
| Urban Farmer cauliflower crust | 4.2 g | 48 g (1/4 crust) | 2.0 g |
| Market Pantry (Target) whole wheat crust | 3.5 g | 57 g (1/4 crust) | 2.0 g |
| PICS cauliflower crust | 3.2 g | 63 g | 2.0 g |
| 365 Whole Foods Market cauliflower crust | 1.8 g | 56 g (1/4 crust) | 1.0 g |
| Pillsbury Classic refrigerated white-flour crust | 1.5 g | 65 g (1/6 crust) | 1.0 g |
Read that table on its own terms. Nothing’s on these crusts, so they don’t line up against the slice table above, where sauce and cheese add weight and drag the per-100-gram number down. And they’re single-brand numbers reported off a company’s own label, not lab-analyzed averages. Change the recipe, change the row. Records in order: 2596817 (T. Marzetti), 2052491 (Whole Foods Market), 2604706 (Banza LLC), 1985746 (Urban Farmer), 2634634 (Target Stores), 2424592 (Price Chopper), 2425029 (Whole Foods Market), 2738511 (General Mills), checked 2026-07-30 and 2026-07-31 at USDA FoodData Central.
Start at the bottom row, because that’s the crust most carts actually contain. A sixth of a Pillsbury Classic refrigerated crust, enriched bleached wheat flour first on the label, is 1 gram of fiber. That’s the floor everything else gets measured against.
Not much clears it by a lot. Three cauliflower crusts, three answers: 2 grams, 2 grams, 1 gram, so one of them ties plain white dough. “Cauliflower” on the box tells you nothing useful about fiber. The two whole wheat crusts split the same way, 3.0 grams for the 365 organic thin crust against 2.0 for Market Pantry’s, one label opening with whole wheat flour and the other with water.
Why a white-flour slice lands between 2 and 3 grams
Worth separating two numbers before going further: the bare crust is about 1 gram per serving in label data, while a finished slice, sauce and cheese included, is the 2 to 3 grams USDA measures. This section is about the finished slice. The flour explains almost all of it. USDA lists white all-purpose flour at 2.7 grams of fiber per 100 grams (record 168894) and whole-grain wheat flour at 10.7 (record 168893). Refining strips the bran and germ, where the fiber lives, so the dough starts at roughly a quarter of the fiber before a topping goes on.
Dilution finishes the job. Water, sauce and cheese add weight without adding fiber, so a white-flour slice lands between 2 and 3 grams however the chain styles it. FDA’s general guide calls 20 percent of the Daily Value or more “high” for a nutrient, meaning 5.6 grams per serving for fiber. Not one finished slice in the table above clears that bar.
Does whole wheat crust actually have more fiber?
It does, just not the doubling you see repeated everywhere. Gram for gram, USDA’s whole wheat crust records run 50 to 80 percent higher than regular crust, 3.5 to 3.9 grams per 100 grams against 2.2 to 2.3. Per slice that’s 1.5 to 2.2 extra grams, so a three-slice dinner picks up about 5. Biggest swing available at a delivery counter.
The catch is menu language. “Wheat crust” and “multigrain” aren’t 100 percent whole wheat. If the ingredient list starts with anything else, expect the white-flour rows above.
Is cauliflower crust higher in fiber than regular crust?
Not from national averages, because USDA hasn’t lab-analyzed a cauliflower crust for its survey or Standard Reference tables. The brand label data above is what exists, and it swings from 1.8 to 4.2 grams per 100 grams of bare crust, against 1.5 for Pillsbury’s refrigerated white-flour crust in the same dataset. The worst cauliflower crust barely beats plain white dough, the best roughly triples it. Which means you read the box. Caulipower’s original crust lists cauliflower first, then brown rice flour, rice flour, water, corn starch and tapioca starch, and those refined starches are close to fiber-free. That’s the freezer-aisle pattern: the vegetable leads, the binders quietly follow.
The vegetable was never going to carry it anyway. USDA puts raw cauliflower at 2 grams of fiber per 100 grams (record 169986), so a cup of chopped florets is about 2 grams. To skip the label roulette, our homemade high-fiber cauliflower pizza crust puts you in charge of the dough.
What about chickpea, almond and sprouted-grain crusts?
The raw materials look great on paper. Chickpea flour carries 10.8 grams of fiber per 100 grams in USDA’s data (record 174288), four times white flour, and NIDDK lists chickpeas among the better sources of fiber alongside whole grains. Banza’s crust starts its ingredient list with chickpeas. Blanched almonds sit at 9.9 grams per 100 grams (record 170568).
Here’s the honest limitation. USDA has never lab-analyzed a national average for a finished legume, nut or sprouted-grain crust, so everything in FoodData Central here is whatever the manufacturer submitted off its own label. And a crust is never just its headline ingredient. Water, starch and fat go in too, which is why Banza’s finished crust reports 6.2 grams per 100 grams even though chickpea flour alone tests at 10.8. The panel on the box beats any per-crust average. If legumes win you over, these high fiber pasta alternatives pull the same trick with noodles.
Thick crust versus thin crust: which has more fiber?
Per 100 grams they’re twins: 2.3 grams for thin restaurant crust, 2.2 for thick. Per slice thick wins, about 2.9 against 2.0, purely on weight. A thick slice runs 132 grams, a thin one 86. So thin crust isn’t a fiber downgrade or a health halo, it’s less food, which is a calorie decision. The real loser is stuffed crust at 1.7 grams per 100 grams, because the cheese in the rim displaces dough.
Which crust should you actually buy?
Depends where you’re standing. At a delivery counter whole wheat is the pick and it isn’t close, and it’s the one upgrade backed by a national USDA average instead of a marketing claim. In a grocery store you can do better: the best rows in the crust table above are sprouted whole grain, chickpea and the 365 organic whole wheat thin crust, 5.0, 3.0 and 3.0 grams per serving of bare crust against 1 gram for plain refrigerated white dough. Whole wheat still holds up on the shelf, just not automatically, since Market Pantry’s version lands at 2.0. Cauliflower crusts depend entirely on how much starch the brand used, so check the label every time. And “sprouted” describes a process, not a fiber count. What lifted that top row was whole grain.
Keep going down the specialty shelf and the numbers get strange. USDA’s Branded Foods dataset also carries engineered high-fiber crusts, like ThinSlim Foods’ at 24.7 grams per 100 grams, 14 grams in a quarter-crust serving (record 2585780). That’s not flour doing the work. The ingredient list opens with wheat protein isolate and oat fiber, which is a different product category wearing a pizza costume.
The bigger lever isn’t the base at all. Using USDA values, half a cup of cooked broccoli adds about 2.6 grams of fiber, half a cup of artichoke hearts about 4.8, and a tablespoon of ground flaxseed about 1.9. Pile those on a white-flour pie and you’ll beat a bare whole wheat one. If cost is the constraint, we ran the numbers on which high-fiber foods give you the most fiber per dollar, because the cheapest fiber in the store has never been in the pizza aisle.
