What is the normal range for blood sugar?

In general, the American Diabetes Association’s (ADA) recommended blood sugar levels are:

  • Between 70 and 130 mg/dL before meals
  • Less than 180 mg/dL after meals

Your range is yours alone—based on your health, age, level of activity and other factors. And remember that your target is a range you’d like to stay within, not a single number.
