Croissants are a beloved breakfast pastry, but their carbohydrate content can vary significantly depending on size, recipe, and added ingredients. This calculator helps you determine the exact carbohydrate content per 100 grams of croissant, making it easier to track your macros and plan your meals.
Whether you're following a low-carb diet, managing diabetes, or simply curious about the nutritional profile of your favorite pastry, this tool provides accurate estimates based on standard USDA food data. Simply enter the total weight of your croissant and the number of croissants you're eating, and the calculator will compute the carbs per 100g, along with total carbs, calories, and other useful metrics.
Perfect for nutritionists, fitness enthusiasts, and anyone who wants to make informed dietary choices. Use the quick-fill buttons for common croissant sizes to get instant results.

How to Use This Tool
Using the Croissant Carbs Per 100g Calculator is straightforward. Start by entering the total weight of your croissant in grams or ounces. If you're eating more than one, specify the number of croissants. The calculator then uses standard USDA nutritional data for a plain butter croissant to compute the carbohydrate content per 100 grams, as well as the total carbs, calories, protein, fat, and fiber for your entire serving.
For quick estimates, use the preset buttons for common croissant sizes: small (57g), medium (67g), and large (85g). These are typical weights found in bakeries and grocery stores. After clicking "Calculate," you'll see a breakdown of all macronutrients, including net carbs (total carbs minus fiber), which is particularly useful for low-carb or ketogenic diets.
Formula Explained
The calculation is based on the nutritional composition of a plain croissant per 100 grams. According to the USDA FoodData Central, a typical croissant contains approximately:
- Carbohydrates: 45.8 g
- Protein: 8.2 g
- Fat: 21.0 g
- Fiber: 2.6 g
- Calories: 406 kcal
To find the total carbs for your serving, the formula is:
Total Carbs = (Carbs per 100g / 100) × Total Weight (g)
For example, if you have a 67g croissant, the total carbs would be (45.8 / 100) × 67 = 30.7 g.
Net carbs are calculated by subtracting fiber from total carbs, since fiber is not digested like other carbohydrates. This is a key metric for those tracking ketogenic macros.
Worked Examples
Example 1: Single Medium Croissant
Weight: 67g, Count: 1
Total carbs = (45.8/100) × 67 = 30.7 g
Net carbs = 30.7 - (2.6/100 × 67) = 30.7 - 1.7 = 29.0 g
Calories = (406/100) × 67 = 272 kcal
Example 2: Two Large Croissants
Weight: 85g each, Count: 2
Total weight = 170g
Total carbs = (45.8/100) × 170 = 77.9 g
Total calories = (406/100) × 170 = 690 kcal
Factors Affecting Accuracy
The nutritional values used in this calculator are averages for a plain, butter croissant. Actual values can vary based on several factors:
- Recipe variations: Some croissants use more butter or sugar, increasing fat and carbs.
- Brand differences: Commercial croissants may have different formulations, especially if they are filled or flavored.
- Size and density: A larger croissant may not be exactly proportional in nutrients; the per-100g values can differ slightly.
- Preparation method: Croissants made with whole wheat flour will have more fiber and slightly different carb counts.
For the most accurate tracking, always check the nutrition label on packaged products or use the USDA database for specific brands.
Frequently Asked Questions
Are croissants high in carbs?
Yes, croissants are considered a high-carb food. With about 45.8g of carbs per 100g, a typical medium croissant (67g) contains roughly 30g of carbs, which is about 10% of a standard 300g daily carb allowance.
What is the difference between total carbs and net carbs?
Total carbs include all carbohydrates, including fiber. Net carbs subtract fiber because fiber is not fully digested and has minimal impact on blood sugar. For low-carb diets, net carbs are often the more relevant number.
Can I use this calculator for filled croissants?
No, this calculator is designed for plain croissants. Filled croissants (chocolate, almond, etc.) have significantly different nutritional profiles. For those, you would need to adjust the per-100g values based on the specific filling.
How many calories are in a croissant?
A plain croissant has about 406 calories per 100g. A medium 67g croissant provides approximately 272 calories. This can vary by brand and recipe.
