One full cracker sheet is about 65 calories, before the marshmallow and chocolate. On the energy-density scale, 430 kcal per 100 g puts graham crackers at the very high end. Fiber is the standout at 3.4 g per 100 g, which slows a portion down more than the calorie count suggests.
A typical serving (1 cracker, 15 g) has about 65 calories, and 100 g has 430 kcal. Calories scale with weight, so double the portion means double the number.
There are 6.7 g of protein in 100 g of graham crackers, which works out to about 1 g per serving (1 cracker). Treat it as an energy source rather than a protein source.
Sugar comes to 24.8 g per 100 g, so 1 cracker (15 g) delivers roughly 4 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 174957 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
