A cholesterol levels chart by age is most accurate when it shows two things clearly: children and teens have their own healthy ranges, while most adults and seniors use the same basic cholesterol cutoffs. What changes most with age is screening frequency and how your results are interpreted with your overall heart and stroke risk.
High cholesterol usually does not cause symptoms. That is why a simple chart is helpful, but it is only the starting point. Your lipid panel matters most when it is read alongside factors like blood pressure, diabetes, smoking, kidney disease, family history, and any past heart attack or stroke. The CDC and the American Heart Association both emphasize this bigger picture.
Important: This chart is for general education. It does not diagnose disease or replace personal medical advice, especially if you already have cardiovascular disease, diabetes, chronic kidney disease, or a strong family history of very high cholesterol.
Cholesterol levels chart by age at a glance
The most practical by-age chart comes from MedlinePlus, with added screening context from NHLBI. For children, the healthy ranges are different. For adults and seniors, the core cutoffs stay mostly the same, although LDL goals may be lower in people at higher risk.
| Age group | Total cholesterol | Non-HDL cholesterol | LDL cholesterol | HDL cholesterol | Triglycerides | What to know |
|---|---|---|---|---|---|---|
| Children and teens (19 and younger) | Less than 170 mg/dL | Less than 120 mg/dL | Less than 110 mg/dL | More than 45 mg/dL | Less than 75 mg/dL up to age 9; less than 90 mg/dL ages 10 to 19 | Children use different healthy ranges from adults |
| Adults (20 to 64) | Less than 200 mg/dL | Less than 130 mg/dL | Less than 100 mg/dL | 60 mg/dL or higher is best | Less than 150 mg/dL | Low HDL is less than 40 mg/dL in men and less than 50 mg/dL in women |
| Seniors (65 and older) | Less than 200 mg/dL | Less than 130 mg/dL | Less than 100 mg/dL for many people | 60 mg/dL or higher is best | Less than 150 mg/dL | Basic adult ranges still apply, but follow-up is more individualized |
These are the most useful healthy-range targets for readers. They are not treatment goals for every person. The American Heart Association notes that some people need LDL goals below 70 mg/dL, and those at very high risk may need goals below 55 mg/dL.
How to read adult results that are above the healthy range
Healthy targets are useful, but many adults want to know what “borderline” or “high” actually means on a lab report. According to MedlinePlus LDL guidance, MedlinePlus total cholesterol guidance, and MedlinePlus triglyceride guidance, these are the most practical adult interpretation ranges.
| Test | Healthy or optimal | Near optimal / borderline | High |
|---|---|---|---|
| Total cholesterol | Less than 200 mg/dL | 200 to 239 mg/dL | 240 mg/dL or higher |
| LDL cholesterol | Less than 100 mg/dL | 100 to 129 mg/dL = near optimal; 130 to 159 mg/dL = borderline high | 160 to 189 mg/dL = high; 190 mg/dL or higher = very high |
| Triglycerides | Less than 150 mg/dL | 150 to 199 mg/dL = borderline high | 200 mg/dL or higher |
This extra context helps explain why an adult can have a result that is not yet “high” but still deserves attention, repeat testing, or a conversation about overall cardiovascular risk.
What the numbers mean
Total cholesterol
Total cholesterol is the overall amount of cholesterol in your blood. For most adults, a level below 200 mg/dL is desirable. In children and teens, the healthy target is below 170 mg/dL. Total cholesterol is useful, but it should not be interpreted alone because LDL, HDL, non-HDL, and triglycerides give a clearer picture of risk.
LDL cholesterol
LDL is often called the “bad” cholesterol because it contributes to plaque buildup in the arteries. For many adults, less than 100 mg/dL is a good general target. But there is not one LDL goal that fits everyone. The right goal depends on your overall risk profile.
That is why current guidance can look different from one person to another. For some people, an LDL goal below 100 mg/dL is appropriate. For others, especially those at higher risk, the goal may be below 70 mg/dL. In very high-risk secondary prevention, the 2026 dyslipidemia guideline recommends an LDL-C goal below 55 mg/dL and a non-HDL-C goal below 85 mg/dL.
HDL cholesterol
HDL is often called the “good” cholesterol because it helps carry cholesterol away from artery walls. In adults, 60 mg/dL or higher is considered best. HDL is considered low at less than 40 mg/dL in men and less than 50 mg/dL in women. In children and teens, a healthy HDL level is more than 45 mg/dL.
Non-HDL cholesterol and triglycerides
Non-HDL cholesterol includes LDL and other cholesterol particles that can contribute to artery disease. Healthy non-HDL is under 120 mg/dL for children and under 130 mg/dL for adults. Triglycerides are not cholesterol, but they are part of most lipid panels and matter for heart health. In adults, triglycerides below 150 mg/dL are considered healthy, 150 to 199 mg/dL is borderline high, and 200 mg/dL or more is high.
Why adult cholesterol is not truly age-specific
This is the part many readers need most. There is no official decade-by-decade adult cholesterol chart where your normal LDL or total cholesterol automatically changes at age 30, 40, 50, or 70. Adults and seniors generally use the same main cutoffs. What changes is how likely abnormal results are to appear with age, how often testing is recommended, and how aggressively high-risk patients are treated.
Age still matters. Cholesterol levels often rise as people get older, and recent CDC/NCHS data show that high total cholesterol was more common in adults ages 40 to 59 than in adults ages 20 to 39 during August 2021 to August 2023. That does not mean higher numbers become healthy with age. It means abnormal results become more common and deserve more attention.
Cholesterol screening schedule by age
A cholesterol levels chart by age is most useful when you pair it with an age-based testing schedule. The NHLBI diagnosis page and CDC guidance give a practical screening framework for children, adults, and older adults.
| Age group | Usual screening guidance |
|---|---|
| Children | At least once between ages 9 and 11 |
| Adolescents and young adults | Again between ages 17 and 21 |
| Healthy adults | Usually every 4 to 6 years |
| Men 45 to 65 | Often every 1 to 2 years |
| Women 55 to 65 | Often every 1 to 2 years |
| Adults older than 65 | Yearly screening is commonly recommended |
CDC says most healthy adults should have cholesterol checked every 4 to 6 years. NHLBI adds more age detail, including yearly screening for adults older than 65. Children with obesity, diabetes, or a strong family history may need earlier or more frequent screening. NHLBI also notes that screening may start as early as age 2 when family history raises concern.
Healthy cholesterol ranges for children, adults, and seniors
Children and teens
Children are not just small adults when it comes to cholesterol. Their healthy targets are lower for total cholesterol, non-HDL, and LDL, while HDL should stay above 45 mg/dL. MedlinePlus guidance on high cholesterol in children and teens and MedlinePlus’ pediatric encyclopedia both stress that family history, obesity, diabetes, and certain inherited conditions can raise risk.
One child-specific detail worth knowing is triglycerides. The healthy cutoff changes by age. For children up to age 9, triglycerides should be less than 75 mg/dL. For ages 10 to 19, they should be less than 90 mg/dL.
| Pediatric triglyceride range | Healthy |
|---|---|
| Ages 0 to 9 | Less than 75 mg/dL |
| Ages 10 to 19 | Less than 90 mg/dL |
That helps explain why a child’s triglyceride result should not be judged by adult cutoffs.
Recent U.S. data show why this matters. The CDC/NCHS March 2026 data brief reported that 16.5% of children and adolescents ages 6 to 19 had at least one abnormal cholesterol measure during August 2021 to August 2023.
Adults
For most adults, the most useful quick targets are total cholesterol under 200, non-HDL under 130, LDL under 100, HDL 60 or higher as best, and triglycerides under 150. Adults with abnormal numbers often need follow-up based not only on the lipid panel, but also on blood pressure, smoking status, diabetes, kidney disease, family history, and overall cardiovascular risk.
During August 2021 to August 2023, 11.3% of U.S. adults age 20 and older had high total cholesterol, according to CDC/NCHS. In the same report, prevalence was highest among adults ages 40 to 59.
Seniors
Seniors generally do not have a separate normal cholesterol chart just because they are older. The main adult ranges still apply. What changes is that older adults are more likely to need yearly screening and more personalized treatment decisions.
That is why two people in their 70s can have the same lipid panel but receive different advice. One may need lifestyle changes and monitoring. Another may need medication because of diabetes, chronic kidney disease, a prior heart attack, or a prior stroke. Current AHA guidance supports using both age and overall ASCVD risk when setting treatment goals.
What cholesterol results may be concerning
A healthy-range chart is helpful, but readers also want to know what usually counts as a warning sign. In adults, total cholesterol of 240 mg/dL or higher is high. LDL of 160 mg/dL or higher is high, and 190 mg/dL or higher is very high. Low HDL is less than 40 mg/dL in men and less than 50 mg/dL in women. Triglycerides of 200 mg/dL or more are high.
Very high LDL or a strong family history can point to an inherited disorder rather than a simple lifestyle issue. That is especially important when high cholesterol shows up in a child, teen, or young adult.
Familial hypercholesterolemia: when high cholesterol may run in families
Familial hypercholesterolemia, often called FH, is an inherited condition that causes very high LDL cholesterol and raises the risk of early heart disease and stroke. According to the American Heart Association’s FH page, if one person in a family has FH, parents, siblings, and children should be checked as well.
This is one reason age alone should never reassure you that a very high cholesterol result is “normal for your age.” If cholesterol is unusually high early in life, inherited risk may be part of the picture.
How cholesterol is measured
Cholesterol is usually measured with a lipid panel, also called a lipoprotein panel. It commonly includes total cholesterol, LDL, HDL, non-HDL, and triglycerides. Some tests are fasting and some are nonfasting, so it is best to follow the instructions you are given before the test. The MedlinePlus medical test page explains both approaches.
How to improve cholesterol levels at any age
Eat in a heart-healthier way
The CDC’s prevention guidance recommends foods naturally high in fiber, such as oatmeal and beans, while cutting back on saturated fat. MedlinePlus also notes that unhealthy eating patterns and too much saturated fat can raise LDL cholesterol.
Move regularly
Regular physical activity supports healthier cholesterol levels and overall heart health. CDC recommends at least 2 hours and 30 minutes of moderate-intensity physical activity each week for adults, and children and adolescents should be active for 1 hour each day.
Work toward a healthy weight
Overweight and obesity can raise LDL and triglycerides and increase heart disease risk. Even modest improvements in eating patterns and activity can help improve the lipid profile over time.
Avoid smoking and limit alcohol
Smoking lowers HDL and raises cardiovascular risk. Drinking too much alcohol can raise total cholesterol and triglycerides. These are two modifiable factors worth addressing at any age.
Use medication when lifestyle changes are not enough
Some people can improve cholesterol with lifestyle changes alone. Others need statins or other lipid-lowering medication because their overall risk is high or because inherited high cholesterol is involved. Medication decisions should be based on a full clinical picture, not a chart alone.
When to talk to a clinician sooner
Do not wait for your next routine check if you already know your cholesterol is above the healthy range, you have heart disease, diabetes, kidney disease, or you have a close family history of very high cholesterol, early heart attack, or early stroke. The same is true for children with obesity, diabetes, or a strong family history.
FAQ
Do cholesterol levels normally rise with age?
Often, yes. Cholesterol levels tend to rise as people get older. But that does not mean higher cholesterol becomes healthy or expected enough to ignore.
Do seniors have different normal cholesterol numbers?
Usually no. Seniors generally use the same adult reference ranges, but screening and treatment decisions become more individualized with age and medical history.
How often should adults get their cholesterol checked?
Most healthy adults should be checked every 4 to 6 years. Adults older than 65 are commonly screened every year, and some midlife adults need testing every 1 to 2 years depending on age and risk.
Can children really have high cholesterol?
Yes. Children can have abnormal cholesterol, especially with obesity, diabetes, or inherited conditions such as familial hypercholesterolemia. Recent CDC data show that 16.5% of children and adolescents had at least one abnormal cholesterol measure during August 2021 to August 2023.
Is one cholesterol number enough to judge heart risk?
No. LDL, HDL, non-HDL, triglycerides, age, blood pressure, diabetes, smoking, kidney disease, family history, and any history of cardiovascular disease all matter. A chart is helpful, but it is only a starting point.
The bottom line
A useful cholesterol levels chart by age should show different healthy ranges for children and teens, then explain that adults and seniors mostly use the same basic cholesterol targets. The real age-related differences are screening frequency, risk assessment, and how aggressive treatment should be.
If you have not had a lipid panel in a while, a practical next step is to get tested, review the full panel in context, and use the chart as a guide rather than a diagnosis. Catching a problem early can make a meaningful difference for long-term heart health.
