Tortilla Carb Counts by Type and Size
The carbohydrate content of a tortilla is not a single number but depends on several factors, with the primary ones being the type of grain used and the tortilla's size. Different grains and manufacturing processes result in varied nutritional profiles, meaning a corn tortilla's carb count will differ from a flour tortilla's. Generally, corn tortillas are a lower-carb option, while standard flour tortillas contain a higher amount. Whole wheat versions can also impact the fiber and net carb count.
Corn Tortillas: A Lower-Carb Choice
Corn tortillas are a traditional staple in many Mexican dishes and are generally considered a lower-carb alternative to flour tortillas. They are made from nixtamalized corn, a process that improves nutritional value and makes them naturally gluten-free.
- Small (6-inch) Corn Tortilla: A standard small corn tortilla contains approximately 15 grams of total carbohydrates.
- Medium (44-gram) Corn Tortilla: A slightly larger medium corn tortilla has around 19.6 grams of total carbs, with about 2.77 grams of fiber, resulting in approximately 16.83 grams of net carbs.
- Health Benefits: Corn tortillas are also a source of whole grains and provide fiber, which aids digestion and can help manage blood sugar levels.
Flour Tortillas: Higher Carbs for Flexibility
Flour tortillas, made from wheat flour, are known for their soft, pliable texture, making them ideal for dishes like burritos. However, this flexibility comes with a higher carbohydrate count, which increases with size.
- Small (6-inch) Flour Tortilla: A small flour tortilla has about 15 grams of total carbohydrates.
- Medium (8-inch) Flour Tortilla: An 8-inch flour tortilla contains a higher carb count, typically around 25 grams.
- Large (12-inch) Flour Tortilla: For those extra-large burritos, a 12-inch flour tortilla can contain nearly 60 grams of carbohydrates.
Specialty and Low-Carb Tortillas
For those on a ketogenic or low-carb diet, many brands now offer specialized tortillas with significantly reduced carbohydrate content. These are typically made with alternative flours and high-fiber ingredients.
- Almond Flour Tortillas: Made with almond flour, these tortillas can contain as few as 3 grams of net carbs per serving.
- Coconut Flour Tortillas: Another popular low-carb option, coconut flour tortillas typically have around 6 grams of net carbs.
- Zero Net Carb Tortillas: Some brands, like Mission Foods, have developed tortillas that contain high amounts of fiber, allowing for a net carb count of zero.
- Cauliflower Tortillas: Using a base of cauliflower mixed with eggs and cheese, these can offer as little as 1 gram of net carbs per tortilla.
Comparison Table: Corn vs. Flour Tortillas
To better understand the nutritional differences, here is a comparison of typical medium-sized corn and flour tortillas.
| Nutritional Aspect | Corn Tortilla (Medium) | Flour Tortilla (Medium) |
|---|---|---|
| Total Carbohydrates | ~19.6 grams | ~22.2 grams |
| Dietary Fiber | ~2.77 grams | ~1.58 grams |
| Net Carbs | ~16.8 grams | ~20.6 grams (approximate) |
| Calories | ~96 kcal | ~138 kcal |
| Fat | ~1.25 grams | ~3.6 grams |
| Protein | ~2.51 grams | ~3.69 grams |
| Gluten-Free? | Yes, naturally | No |
Making Your Choice: What Matters Most?
Choosing between a corn and flour tortilla depends on your personal dietary needs and preferences. For those watching their carb intake, a smaller corn tortilla or a specialty low-carb option is the clear winner. However, for a larger, more flexible wrap, a flour tortilla is often preferred, but it's important to be mindful of its higher carb and calorie content. A whole wheat flour tortilla can also offer a nutritional middle ground with added fiber compared to refined white flour tortillas.
Conclusion
The number of carbs in a tortilla shell is not a fixed value and depends heavily on the size and type. Corn tortillas are generally lower in carbs, higher in fiber, and naturally gluten-free. Flour tortillas, while more versatile for certain meals, contain more carbohydrates, fat, and sodium. For those on a strict low-carb diet, many excellent specialty alternatives are available, from almond flour to zero-net-carb versions. Ultimately, the best tortilla for you is one that fits your overall nutritional goals while still allowing you to enjoy your food. By checking nutrition labels and being aware of portion sizes, you can make informed choices to support your healthy eating plan.

Understanding Net Carbs
When considering carbohydrate intake, especially for low-carb diets, understanding the concept of "net carbs" is useful. Net carbs are calculated by subtracting the dietary fiber and sometimes sugar alcohols from the total carbohydrates. Because fiber is a type of carb that the body doesn't digest and absorb for energy, it doesn't raise blood sugar levels in the same way as other carbohydrates. This makes the net carb count a more relevant number for some people monitoring their intake.
For example, a corn tortilla might have 19.6 grams of total carbs and 2.77 grams of fiber. This would give it a net carb count of approximately 16.83 grams. By contrast, a low-carb tortilla might have 19 grams of total carbs but 19 grams of fiber, resulting in 0 net carbs. It's crucial to check the nutrition label for the specific fiber content of any specialty low-carb tortilla you purchase, as products can vary widely.
