If you've ever looked at a glucose meter reading and wondered "is that... good?" — you're not alone. Blood sugar targets differ depending on when you tested, whether you have diabetes, and what your doctor has set as your personal goal. Here's a plain-language breakdown.
Normal Ranges (Without Diabetes)
| Test | Typical Normal Range |
|---|---|
| Fasting glucose | 70–99 mg/dL |
| 2 hours after eating (postprandial) | Under 140 mg/dL |
ADA Targets for People With Diabetes (2026 Standards of Care)
For most non-pregnant adults with diabetes, the American Diabetes Association's current guidance recommends:
- A1C target: below 7% for most adults (your doctor may set a different, personalized target)
- Before meals (preprandial): 80–130 mg/dL
- Peak after meals (postprandial): below 180 mg/dL
- Time in Range (TIR): more than 70% of readings within your target range, for people using continuous glucose monitors
Why Your Number Might Be Different
These are general reference ranges, not one-size-fits-all rules. Age, pregnancy, other health conditions, how long someone has had diabetes, and risk of low blood sugar episodes can all shift what target range is appropriate for a given person. Older adults or people with certain health complications are often given a somewhat looser target for safety reasons.
The Takeaway
A blood sugar chart is a helpful reference point, not a diagnosis. If your numbers are consistently outside the typical range, or you're not sure what target is right for you, the most useful next step is a conversation with your doctor — they can set a target based on your full health picture.
