The general weight of 1.65 meters should be 50.3~65.1kg, the standard weight is only for reference and may not be suitable for everyone. At present, the more commonly used formula for calculating standard height and weight is BMI (Body Mass Index), BMI = weight (kg)/height² (cm²). Healthy adults should generally have a BMI of 18.5 to 23.9, with <18.5 being thin, ≥24 being overweight, and ≥28 being obese. According to the lowest value of normal BMI, the lowest weight of 1.65 meters should be 50.3kg; according to the highest value of normal BMI, the highest weight of 1.65 meters should be 65.1kg. However, the so-called "standard weight" refers to the weight that can maintain a healthy state, and the BMI index only reflects the relationship between height and weight, and the weight is also related to gender, age, genetic factors, and different personal circumstances, so there is no need to deliberately pursue a standard weight. There is no absolute standard weight for individuals, and it is recommended to analyze the actual situation of individuals.
