The Institute of Medicine says men and women need at least 130 grams of carbohydrates, pregnant women require a minimum of 175 grams and women who are breastfeeding need at least 210 grams of carbs each day.
It's easier to count the actual grams of carbs, because that's how they're listed on nutritional facts labels. Carbs typically contain four calories per gram, so if your recommended intake is 900 to 1300 calories, you'd divide that by four to arrive at 225 to 325 grams. According to the Dietary Guidelines, the actual carb consumption by most women is on the lower end of that range.
