A good total cholesterol level for adults is below 200 mg/dL, with LDL (the “bad” kind) below 100 mg/dL and HDL (the “good” kind) at 60 mg/dL or above. But those headline numbers only tell part of the story. Your ideal targets depend on your age, sex, and overall heart disease risk.
LDL Cholesterol: The Number That Matters Most
LDL cholesterol is the type that builds up inside artery walls and drives heart disease. It gets the most attention from doctors for good reason. Here’s how the standard categories break down for adults:
- Below 100 mg/dL: Optimal
- 100 to 129 mg/dL: Near optimal
- 130 to 159 mg/dL: Borderline high
- 160 to 189 mg/dL: High
- 190 mg/dL and above: Very high
Those categories are a starting point, not a final answer. The newest guidelines from the American Heart Association and American College of Cardiology, published in 2026, bring back specific LDL targets tied to your personal risk level. If you already have heart disease or are at very high risk, the recommended goal is an LDL below 55 mg/dL. If your 10-year risk of a cardiovascular event is 10% or higher, the target drops to below 70 mg/dL. For people at lower risk, staying under 100 mg/dL is generally sufficient.
In other words, “good” LDL is relative. A level of 95 mg/dL might be perfectly fine for a healthy 35-year-old but too high for someone who has already had a heart attack.
HDL Cholesterol: Higher Is Better, to a Point
HDL works like a cleanup crew, carrying excess cholesterol away from your arteries and back to the liver for disposal. Unlike LDL, you want this number to be high.
- 60 mg/dL and above: Best, considered protective against heart disease
- 40 to 59 mg/dL (men) or 50 to 59 mg/dL (women): Normal range
- Below 40 mg/dL (men) or below 50 mg/dL (women): Low, and a risk factor on its own
There is a ceiling, though. HDL above 80 mg/dL doesn’t appear to provide additional protection and may even be associated with other health issues. The sweet spot for most people falls between 60 and 80 mg/dL.
Triglycerides: The Often-Overlooked Number
Triglycerides are a different type of fat in your blood, fueled heavily by sugar, alcohol, and excess calories. A desirable triglyceride level is below 150 mg/dL. When triglycerides climb above 200 mg/dL, they become an independent risk factor for heart disease, and they also make your other cholesterol numbers less reliable. High triglycerides can cause standard blood tests to underestimate how much harmful cholesterol is actually circulating.
Non-HDL Cholesterol: A Broader Picture
Your lab results may include a number called non-HDL cholesterol. This is simply your total cholesterol minus your HDL, and it captures all the potentially harmful types of cholesterol in one figure, not just LDL. For adults 20 and older, a healthy non-HDL level is below 130 mg/dL. For children and teens 19 and under, the target is below 120 mg/dL.
Non-HDL is gaining traction as a clinical marker because it accounts for other artery-clogging particles that LDL alone misses, particularly in people with high triglycerides or diabetes. The updated 2026 guidelines now set non-HDL goals alongside LDL goals: below 100 mg/dL for high-risk adults and below 85 mg/dL for those at very high risk.
Healthy Ranges for Children and Teens
Children and teenagers have their own set of targets, and they’re stricter than adult ranges because cholesterol buildup starts earlier than most people realize. For anyone 19 or younger:
- Total cholesterol: Below 170 mg/dL
- LDL: Below 110 mg/dL
- HDL: Above 45 mg/dL
- Non-HDL: Below 120 mg/dL
Screening is typically recommended at least once between ages 9 and 11, and again between 17 and 21. Children with a family history of early heart disease or very high cholesterol may be tested earlier.
Why Your Personal Risk Changes the Target
A cholesterol panel doesn’t exist in a vacuum. Two people with identical LDL numbers can face very different levels of risk depending on factors like age, blood pressure, diabetes, smoking status, and family history. The updated guidelines recommend that doctors use a newer risk calculator called PREVENT, developed by the American Heart Association, to estimate your chance of a cardiovascular event over the next 10 or even 30 years.
If your 10-year risk falls below 3%, mildly elevated LDL may not require medication. Between 3% and 5% (borderline risk), treatment becomes something to consider. At 5% to 10% (intermediate risk), cholesterol-lowering therapy is more strongly recommended. Above 10%, the goal is aggressive: at least a 50% reduction in LDL, typically targeting below 70 mg/dL.
The guidelines also flag a lesser-known blood marker called lipoprotein(a), or Lp(a). About one in five people have elevated levels of this inherited particle. If your Lp(a) is at or above 125 nmol/L (roughly 50 mg/dL), it’s considered a risk-enhancing factor that may call for tighter LDL control. Lp(a) doesn’t show up on a standard cholesterol panel, so you’d need to specifically request the test. It only needs to be checked once in your lifetime since levels are largely genetic and don’t change much.
Fasting vs. Non-Fasting Tests
You may have been told to fast for 9 to 12 hours before a cholesterol test. Fasting is still the standard approach because eating can temporarily raise triglyceride levels and throw off the accuracy of certain calculations. However, many doctors now accept non-fasting panels for routine screening, particularly when they’re primarily looking at LDL and HDL. If your non-fasting triglycerides come back high, your doctor will likely ask you to repeat the test after fasting for a more accurate reading.
What Actually Moves the Numbers
Diet, exercise, and body weight all influence your cholesterol, though the degree varies from person to person. Roughly 70% to 80% of the cholesterol in your blood is made by your liver, which is why genetics play such a large role and why some people have high cholesterol despite eating well.
Replacing saturated fats (red meat, butter, full-fat dairy) with unsaturated fats (olive oil, nuts, fatty fish) can lower LDL by 10% to 15% for many people. Soluble fiber from oats, beans, and fruits helps by binding cholesterol in the gut before it reaches the bloodstream. Regular aerobic exercise is one of the most reliable ways to raise HDL, with consistent activity boosting it by 3 to 6 mg/dL on average. Cutting back on sugar and alcohol is the fastest way to bring down triglycerides.
When lifestyle changes aren’t enough, or when risk is already high, medication becomes part of the picture. Statins remain the first-line treatment and can reduce LDL by 30% to over 50% depending on the dose and specific drug. For people who can’t tolerate statins or need additional lowering, other options exist that work through different mechanisms. The 2026 guidelines emphasize treating to a specific LDL goal rather than simply prescribing a medication and hoping for the best.
