What is a common A1c target in type 2 diabetes?

The American Diabetes Association describes an A1c below 7 percent as a common general goal for many nonpregnant adults with diabetes. However, A1c targets are individualized: a clinician sets the right goal for each person based on their overall health, risk of hypoglycemia, and other factors.

Why do A1c targets differ from person to person?

Targets are personalized because the balance of benefits and risks differs. A tighter goal such as below 6.5 percent may suit some people if it can be reached without significant hypoglycemia, while a looser goal such as below 8 percent may be more appropriate for older adults or people with limited life expectancy, extensive other conditions, or a history of severe low blood sugar.

What does A1c actually measure?

A1c, also called HbA1c, reflects your average blood glucose over roughly the previous two to three months. It is reported as a percentage and is widely used to gauge longer-term glucose control, alongside day-to-day glucose readings.

A1c Targets in Type 2 Diabetes

6 min read · Updated July 2026

A1c is one of the most useful numbers in type 2 diabetes care, because it summarizes glucose control over months rather than moments. But there is no single "correct" A1c for everyone. The right target is individualized, set through shared decision-making with a clinician. This article explains the common goals and, just as importantly, why they vary.

What A1c measures

A1c, also written HbA1c, reflects your average blood glucose over roughly the previous two to three months. It is reported as a percentage: the higher the average glucose, the higher the A1c. Because it captures a longer window, it complements the day-to-day readings covered in our guide to blood sugar levels in type 2 diabetes. This article is part of the broader type 2 diabetes hub.

If you want to see how A1c relates to an estimated average glucose, our HbA1c calculator illustrates the relationship.

The common general goal

The American Diabetes Association (ADA) describes an A1c below 7% as a common general goal for many nonpregnant adults with diabetes. This figure is a widely used reference point, not a universal rule. It reflects a balance between the benefits of lower glucose and the risks that can come with pushing too hard, such as low blood sugar.

Why targets are individualized

The single most important idea in this article is that A1c targets are personalized. Two people with type 2 diabetes can reasonably have different goals because the balance of benefits and risks differs for each of them.

A tighter goal, such as an A1c below 6.5%, may be appropriate for some people if it can be achieved without significant hypoglycemia (low blood sugar) or other harms.
A looser goal, such as an A1c below 8%, may be more suitable for older adults or for people with limited life expectancy, extensive other health conditions, or a history of severe hypoglycemia.

The ADA frames these as examples along a spectrum, chosen through clinical judgment rather than applied mechanically. What matters is that the number fits the person.

Balancing benefits and risks

Lower A1c generally reflects lower average glucose, which is associated with reduced risk of certain diabetes-related complications over time. But aggressively lowering glucose can increase the risk of hypoglycemia, which carries its own dangers, particularly for older adults or those on certain medications. The right target sits where these considerations are balanced for you specifically — which is why it is a clinical decision, not a self-set one.

Shared decision-making with your clinician

Setting an A1c target is best done as a conversation. A clinician weighs your glucose history, medications, other conditions, risk of hypoglycemia, preferences, and goals, and agrees a target with you. That target can also change over time as circumstances change. Your diagnosis and follow-up and ongoing monitoring all feed into it.
