Blood sugar level varies from person to person, and what's considered normal can depend on various factors, like the time of day and whether you've eaten recently.

Fasting Blood Sugar: 70-99 mg/dL considered normal for fasting blood sugar levels, typically measured in morning before eating.

Post-Meal Blood Sugar: 140-180 mg/dL is common target range for blood sugar levels about 1-2 hours after eating.

Hemoglobin A1c (HbA1c): A level of less than 5.7% is generally considered normal.

Random Blood Sugar Level: It below 140 mg/dL is often considered within the normal range, regardless of the last meal.

Pre-Exercise: Before engaging in physical activity, blood sugar levels are often recommended to be between 90-250 mg/dL.

Pre-Bedtime: Before going to sleep, it's ideal for blood sugar levels to be between 90-150 mg/dL.

Continuous Glucose Monitoring (CGM): If you're using a CGM device, the target range can vary but is often set between 70-180 mg/dL.
