- For most adults aged 20 and older, a healthy total cholesterol is below 200 mg/dL, LDL below 100 mg/dL, and HDL at or above 40 mg/dL for men and 50 mg/dL for women (MedlinePlus).
- Children and teens aged 19 and younger have lower targets: total cholesterol below 170 mg/dL, LDL below 110 mg/dL, and HDL above 45 mg/dL (MedlinePlus).
- Cholesterol tends to rise with age, and a woman’s risk climbs after menopause, so the same number can mean different things at 25 versus 60 and is read alongside your overall heart risk (MedlinePlus).

What is a normal cholesterol level?
For an adult aged 20 or older, a normal total cholesterol is below 200 mg/dL, with LDL (“bad” cholesterol) below 100 mg/dL and triglycerides below 150 mg/dL (Cleveland Clinic). HDL (“good” cholesterol) works the opposite way: higher is better, with 60 mg/dL or above considered protective and below 40 mg/dL in men or below 50 mg/dL in women considered low (MedlinePlus).
Cholesterol is a waxy, fat-like substance your body needs to build cells and make hormones. The problem is not cholesterol itself but having too much of the harmful kind. Doctors group results into bands so a single blood draw, called a lipid panel, can flag whether you are in a safe zone or trending toward heart and blood vessel risk.
Total cholesterol: Below 200 mg/dL is normal, 200 to 239 mg/dL is borderline high, and 240 mg/dL or higher is high (Cleveland Clinic).
LDL cholesterol: Below 100 mg/dL is optimal, 130 to 159 mg/dL is borderline high, and 190 mg/dL or higher is very high (Cleveland Clinic).

Cholesterol normal range by age
Healthy cholesterol ranges split into two main groups: people aged 19 and younger have lower targets than adults aged 20 and older, and within adults the HDL goal differs by sex (MedlinePlus). The single most useful number for most people is LDL, which should sit below 110 mg/dL in children and below 100 mg/dL in adults (MedlinePlus).
The table below uses reference values published by MedlinePlus (US National Library of Medicine). These are general targets for people without diagnosed heart disease. If you already have cardiovascular disease or diabetes, your clinician may set a stricter LDL goal, often below 70 mg/dL (Cleveland Clinic).
| Group | Total cholesterol | LDL (“bad”) | HDL (“good”) | Non-HDL |
|---|---|---|---|---|
| Children and teens, age 19 and younger | Below 170 mg/dL | Below 110 mg/dL | Above 45 mg/dL | Below 120 mg/dL |
| Men, age 20 and older | Below 200 mg/dL | Below 100 mg/dL | 40 mg/dL or higher (60+ best) | Below 130 mg/dL |
| Women, age 20 and older | Below 200 mg/dL | Below 100 mg/dL | 50 mg/dL or higher (60+ best) | Below 130 mg/dL |
Triglycerides share one target across all ages: below 150 mg/dL is normal, 150 to 199 mg/dL is borderline high, and 200 mg/dL or more is high (MedlinePlus). Notice that the official ranges stop at two age bands rather than giving a different number for every decade. That is deliberate, because the meaningful cutoffs change at sexual maturity and then hold steady, while your underlying risk, not the target itself, drifts with age.
How does sex change the range?
Sex changes only the HDL target in standard reference charts: men aim for 40 mg/dL or higher and women for 50 mg/dL or higher, because women naturally carry more protective HDL (MedlinePlus). Total cholesterol, LDL, and non-HDL goals are identical for adult men and women (MedlinePlus).
The bigger difference is timing. Between ages 20 and 39, men carry a greater risk of high total cholesterol than women (MedlinePlus). Estrogen helps keep a woman’s LDL lower and HDL higher during her reproductive years.
After menopause: a woman’s risk of high blood cholesterol rises because menopause lowers the female hormones that may protect against it (MedlinePlus). LDL and total cholesterol often climb in the years around menopause, sometimes pushing a woman who was always “normal” into the borderline band. This is why a 55-year-old woman’s result deserves a fresh look even if her numbers were fine at 40.
What makes cholesterol rise or fall with age?
Cholesterol generally rises with age because the liver clears LDL less efficiently and lifestyle and hormonal shifts add up over decades. This is why screening targets stay fixed while real-world averages creep upward, and why women often see a jump after menopause as protective estrogen falls (MedlinePlus).
Several forces push the numbers around:
- Diet: saturated and trans fats raise LDL, while soluble fiber and unsaturated fats can lower it.
- Weight and activity: excess body weight tends to raise LDL and triglycerides and lower HDL, while regular exercise nudges HDL up.
- Hormones: the menopause transition removes estrogen’s protective effect on a woman’s lipids (MedlinePlus).
- Genetics: familial hypercholesterolemia causes very high LDL from a young age regardless of lifestyle, which is one reason children get a first screen between ages 9 and 11 (Cleveland Clinic).
- Other conditions: diabetes, thyroid disease, and some medications can shift your panel.
Because lifestyle moves several of these levers, many people lower borderline LDL through diet and exercise before any medication is considered.
When is an out-of-range result a concern?
A single out-of-range result is a signal to look closer, not an automatic diagnosis. LDL of 160 to 189 mg/dL is high and 190 mg/dL or above is very high, while total cholesterol of 240 mg/dL or more is high (Cleveland Clinic). These bands warrant a conversation with your clinician about your overall heart risk.
Context matters more than any one number. Doctors weigh your LDL alongside age, blood pressure, smoking status, diabetes, family history, and HDL to estimate your risk of a heart attack or stroke over the next 10 years. A borderline LDL in an otherwise healthy 30-year-old is handled differently from the same value in a 60-year-old smoker with diabetes.
Take it seriously sooner if: you have known heart disease or diabetes, since your LDL target may be below 70 mg/dL (Cleveland Clinic); you have a strong family history of early heart disease; or your triglycerides reach 200 mg/dL or higher (MedlinePlus). Fasting status, recent illness, and lab variation can all shift results, so clinicians often repeat an abnormal panel before acting. Bring your full lipid panel to your appointment rather than focusing on one figure.
Frequently asked questions
What is a normal cholesterol level by age?
For people aged 19 and younger, total cholesterol should be below 170 mg/dL and LDL below 110 mg/dL. For adults aged 20 and older, total cholesterol should be below 200 mg/dL and LDL below 100 mg/dL (MedlinePlus).
Is 200 cholesterol normal for my age?
A total cholesterol of exactly 200 mg/dL sits at the borderline-high threshold for adults, since normal is below 200 mg/dL and 200 to 239 mg/dL is borderline high (Cleveland Clinic). For anyone 19 and younger, 200 mg/dL is high because their target is below 170 mg/dL.
What is a good HDL cholesterol level?
An HDL of 60 mg/dL or higher is considered protective for adults. HDL is too low below 40 mg/dL in men and below 50 mg/dL in women (MedlinePlus). Unlike LDL, higher HDL is generally better for your heart.
Does cholesterol go up with age?
Yes. Cholesterol tends to rise with age as the liver clears LDL less efficiently. Women often see a notable increase after menopause, when protective estrogen falls and the risk of high blood cholesterol goes up (MedlinePlus).
How often should I get my cholesterol checked?
Children typically get a first cholesterol test between ages 9 and 11 (Cleveland Clinic). Most adults are rechecked every few years, and more often if results are abnormal or you have risk factors. Ask your clinician for a schedule based on your personal risk.
