For a more complete picture, combine BMI with your body fat percentage. The estimated body fat for this BMI is approximately 5301% (Deurenberg formula, assumes male aged 30 — use the body fat calculator for personalised results).

Note that "ideal" weight varies by individual — muscle mass, bone density, age, and ethnicity all affect what's healthy for a specific person.
How accurate is BMI?+
BMI is a useful population-level screening tool but has individual limitations. It doesn't distinguish between fat and muscle mass — a muscular person may have a high BMI despite having low body fat. It also doesn't account for fat distribution (abdominal fat is more associated with health risk than overall BMI). Use BMI alongside waist circumference and body fat percentage for a more complete picture.
