Tortillas are a pantry staple — but carb counts vary widely between flour, corn, whole wheat, and low-carb versions. This calculator converts the numbers on your tortilla nutrition label into a standard per-100g figure, so you can compare brands and types on an equal basis, track macros, and plan meals without guesswork.
Enter the weight and carbohydrate content from the package — or pick a common tortilla type to auto-fill the fields. The tool works out total carbs for any number of tortillas, carbs per 100g, carbs per ounce, and net carbs when you add fiber. It's designed for anyone counting carbs: keto eaters, low-carb dieters, people managing diabetes, or anyone curious about portion sizes. Meal prepping? The count field scales totals to your batch, so you can log a whole meal at once.
Tortilla Carbs Per 100g Calculator
Quick Start: Entering Your Tortilla's Numbers
Start by choosing the tortilla type that matches what you have. The preset values are rough averages from common US brands, so they make it easy to get a ballpark figure in seconds. For meal prep or macro tracking, though, your package label is always more accurate: use the custom option and type in the exact weight and carbohydrate values from the Nutrition Facts panel.
Here is the full workflow:
- Pick a preset, or choose Custom and enter your label values.
- Set the number of tortillas you plan to eat or batch-cook.
- Make sure the weight unit and carb unit match your label; the calculator converts ounces to grams automatically.
- Add fiber per tortilla if you want net carbs.
- Press Calculate and read the main result plus the breakdown below it.
The Math Behind Carbs per 100g
The calculation standardizes any tortilla to a common 100-gram reference, just like food databases do. The formula is simple:
Total carbs ÷ total weight × 100 = carbs per 100g
Because the number of tortillas appears in both the numerator and the denominator, it cancels out mathematically. That means a 30g corn tortilla and a 60g flour tortilla can be compared fairly: the flour tortilla may contain more total carbs per serving, but the corn tortilla's carb density per 100g can be lower. Still, the count field is useful for getting the total carbs in your actual meal, which is what your food diary needs.
Worked Examples
Example 1 — Flour tortilla. Your label says one 60g flour tortilla has 33g of carbohydrates. Carbs per 100g = 33 ÷ 60 × 100 = 55g. If you eat two tortillas, total carbs = 66g, total weight = 120g, and carbs per 100g remains 55g.
Example 2 — Low-carb tortilla with fiber. A 45g tortilla contains 10g total carbs and 9g fiber. Net carbs per 100g = (10 − 9) ÷ 45 × 100 = 2.2g. The total-carb figure would be 22.2g per 100g, which shows why fiber makes such a difference for low-carb eaters.
Reference Table: Common Tortilla Values
| Tortilla type | Typical weight | Carbs per tortilla | Carbs per 100g |
|---|---|---|---|
| Flour (8-inch) | 60 g | 33 g | 55 g |
| Corn (6-inch) | 30 g | 14 g | 47 g |
| Whole wheat (8-inch) | 50 g | 24 g | 48 g |
| Low-carb (8-inch) | 45 g | 10 g | 22 g |
These are approximate values drawn from common nutrition labels and public food databases. Actual numbers vary by brand, recipe, and tortilla size, so always verify with your own package when precision matters.
Tips for Accurate Carb Counting
- Weigh the tortilla yourself instead of trusting the serving size. Commercial tortillas often weigh more or less than the label claim, and even a 5g difference changes the per-100g result.
- Watch for low-carb tortillas with added fiber or sugar alcohols. Net carbs are useful, but if you track total carbs for medical reasons, use the total-carb figure.
- Compare products by per-100g, not by per-tortilla, because tortilla sizes vary so much.
- When you log a meal, remember to include the fillings — the tortilla is only part of the carb picture.
Tip: If you often use the same brand, save the values from your package and simply adjust the number of tortillas each time. This calculator scales all totals for you.
Frequently Asked Questions
What is the difference between total carbs and net carbs? Net carbs are total carbohydrates minus fiber (and sometimes sugar alcohols). Fiber is not digested like other carbs, so many low-carb eaters prefer to track net carbs. Our calculator displays both per-100g values so you can choose the approach that fits your diet.
Why do corn tortillas sometimes have fewer carbs than flour tortillas? Corn tortillas are typically smaller and less dense because they use maize flour, while flour tortillas often include added starches, fat, and sometimes sugar. The per-100g difference may be smaller than you expect, but it still matters for portion control.
Does carbs per 100g equal glycemic index? No. Glycemic index measures how quickly a food raises blood sugar, while this calculator measures carbohydrate quantity by weight. For a more complete view of blood-sugar impact, pair this with our glycemic load calculator.
Where can I find verified nutrition data? The USDA FoodData Central database is a reliable public source for food composition data. You can search for tortillas and compare products there: fdc.nal.usda.gov.
