For most adults, a healthy total cholesterol level is below 200 mg/dL, with LDL (“bad”) cholesterol under 100 mg/dL and HDL (“good”) cholesterol at 60 mg/dL or above. But those numbers are just the starting point. Your ideal targets depend on your age, sex, and cardiovascular risk factors.
The Key Numbers on Your Lipid Panel
A standard cholesterol test measures four things: total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Each tells you something different about your cardiovascular health, and they’re all measured in milligrams per deciliter (mg/dL).
Total cholesterol is the broadest measure. Below 200 mg/dL is considered healthy for adults 20 and older. Between 200 and 239 is borderline high, and 240 or above is high.
LDL cholesterol is the one that matters most for heart disease risk. LDL particles deposit cholesterol in artery walls, gradually forming plaques that narrow blood vessels. For the general population, below 100 mg/dL is the standard goal. If you’re at high risk for cardiovascular disease, your target drops to below 70 mg/dL. For people who already have heart disease and are at very high risk of a future event, the latest guidelines from the American College of Cardiology and American Heart Association push that target even lower, to below 55 mg/dL.
HDL cholesterol works in the opposite direction, helping remove cholesterol from your bloodstream. For men, levels below 40 mg/dL are considered low. For women, the floor is higher at 50 mg/dL. For both, 60 mg/dL or above is ideal.
Triglycerides are a type of fat in your blood that your body uses for energy. Below 150 mg/dL is healthy. Between 150 and 199 is borderline high. Levels from 200 to 499 are high, and anything at or above 500 is very high and carries a risk of pancreas inflammation.
Why HDL Targets Differ for Men and Women
Women naturally tend to have higher HDL levels than men, largely due to the effects of estrogen. That’s why the minimum recommended HDL is 50 mg/dL for women but 40 mg/dL for men. After menopause, women’s HDL levels often decline, which is one reason cardiovascular risk rises in older women. For all other cholesterol measures, the targets are the same regardless of sex: total cholesterol below 200, LDL below 100, and triglycerides below 150.
Cholesterol Targets for Children and Teens
The healthy ranges are tighter for anyone 19 or younger. Total cholesterol should be below 170 mg/dL (not 200, as in adults). LDL should stay under 110 mg/dL, and HDL should be above 45 mg/dL. Non-HDL cholesterol, which captures all the potentially harmful cholesterol particles, should be below 120 mg/dL.
Medication is rarely considered for children. It generally only enters the conversation when a child’s LDL remains above 190 mg/dL after six months of diet and exercise changes, or above 160 mg/dL if they have additional risk factors for heart disease, such as a strong family history.
Non-HDL Cholesterol: A Number Worth Knowing
Your lipid panel may also report non-HDL cholesterol, which is simply your total cholesterol minus your HDL. If your total cholesterol is 180 and your HDL is 60, your non-HDL is 120. This number captures all the cholesterol types that contribute to plaque buildup, not just LDL, making it a useful single figure for assessing risk.
For most adults, a healthy non-HDL level is below 130 mg/dL. If your doctor has set your LDL target at 70 (because of higher cardiovascular risk), your non-HDL target drops to below 100. The rule of thumb: your non-HDL should be no more than 30 mg/dL above your personal LDL target.
How Risk Level Changes Your Target
The general population targets listed above are for people at borderline or intermediate cardiovascular risk. But cholesterol goals aren’t one-size-fits-all. Your overall risk profile, which factors in things like blood pressure, diabetes, smoking status, and family history, determines how aggressively your LDL needs to be lowered.
Here’s how LDL targets shift with risk:
- Borderline or intermediate risk: below 100 mg/dL
- High risk: below 70 mg/dL
- Very high risk (existing heart disease): below 55 mg/dL
Young adults with LDL at or above 160 mg/dL, or those with a strong family history of early heart disease, may also be flagged for earlier treatment. Familial hypercholesterolemia, a genetic condition that causes very high LDL from birth, sometimes requires medication starting in childhood or adolescence.
Do You Need to Fast Before a Cholesterol Test?
Traditionally, doctors required 8 to 12 hours of fasting before a lipid panel. That’s changing. Research published in the Journal of the American College of Cardiology found that eating before the test causes only small shifts in results: triglycerides rise by an average of 26 mg/dL, while LDL and total cholesterol each dip by about 8 mg/dL. HDL is largely unaffected. These differences are clinically insignificant for most people, and guidelines in the U.S., Europe, Canada, the U.K., Denmark, and Brazil now endorse non-fasting lipid panels.
The one situation where this matters is if your LDL is borderline, right around your target. A non-fasting test might show a slightly lower LDL than your true fasting level, which could affect whether treatment is recommended. If your results are on the edge, your doctor may ask you to repeat the test while fasting.
What Your Numbers Mean Together
No single cholesterol number tells the full story. A total cholesterol of 210 might sound concerning, but if most of that is HDL, your risk could actually be low. Conversely, a total cholesterol of 190 with very low HDL and high triglycerides is a worse picture than the number alone suggests.
Non-HDL cholesterol helps cut through this complexity because it bundles all the harmful particles into one figure. Some doctors also look at a protein called apolipoprotein B, which directly counts the number of particles that can deposit cholesterol in artery walls. Levels above 130 mg/dL are considered a risk-enhancing factor for adults in their 40s to 70s, particularly when triglycerides are elevated. This test isn’t routine yet, but it’s increasingly used when standard numbers don’t paint a clear picture.
The practical takeaway: look at all four standard numbers together, pay special attention to LDL and non-HDL, and know that your personal targets may be lower than the general population ranges if you have additional risk factors for heart disease.
