It varies from person to person. Some diabetics can have very few carbs while others appear to be safe with more. You cannot afford to take chances. You need to determine how many carbohydrates are safe for you by testing your blood sugar, with your glucometer, one hour after each meal and then again two hours after the meal.
You may or may not be on insulin, but it you are your carb to insulin ratio is how many carbs you eat with how many units you inject. My carb to insulin ratio is 15:1 so if I eat 60 carbs (I have Diabetes type 1) I will give myself 4 units of insulin.
On the other hand, some people with type 2 diabetics (they are not all on insulin) cannot have much more than 20 to 25 in a day yet others can have far more. You need to test it out for you, as a unique individual, by measuring your blood sugar with your glocometer one hour after, and then two hours after, eating.
