Adults (19 and over)
Targets are the same for most adults regardless of age. Desirable ranges:
- Total cholesterol: under 200 mg/dL (5.2 mmol/L)
- LDL (“bad”): under 100 mg/dL (2.6 mmol/L)
- Non-HDL: under 130 mg/dL (3.4 mmol/L)
- HDL (“good”): 60 mg/dL (1.5 mmol/L) or above; low under 40 (1.0)
- Triglycerides: under 150 mg/dL (1.7 mmol/L)
Children and teens (under 19)
Young people use slightly different cut-offs. Broadly, total cholesterol under 170 mg/dL (4.4 mmol/L) and LDL under 110 mg/dL (2.8 mmol/L) are acceptable. Routine testing isn’t needed for every child, but it’s advised where there’s a family history of very high cholesterol or early heart disease.
Why levels rise with age
Cholesterol tends to increase through adulthood, and after menopause women often see LDL rise as the protective effect of oestrogen falls. The healthy target doesn’t change — but staying within it can take more effort over time.
Your target depends on risk, not just age
People with diabetes, existing heart disease or other risk factors are often given lower LDL goals than the general ranges above. Look at your numbers together — your ratio and non-HDL matter as much as any single figure — and set targets with your clinician.
