Healthy weight by height works as a range: use BMI 18.5–24.9 and a waist-to-height ratio under 0.5 to set a smart target.

At 5’5″ (1.65 m), a healthy weight lands around 111–150 lb (50–68 kg) using BMI 18.5–24.9, with a waist under half your height as a smart check.

For adults, a practical starting point is your healthy weight range for your height using BMI, then cross-check with waist size for central fat.

Most programs use BMI, not a fixed weight: gastric bypass is usually offered at BMI ≥40, or ≥35 with weight-related conditions.

At 6’2, a broad healthy weight range sits near 145 to 195 pounds, but the best target still depends on age, sex, muscle mass, and medical history.

At 5 feet tall, a healthy weight is about 95–127 lb (43–58 kg) based on BMI 18.5–24.9; keep waist under 30 in as a second check.

If you ask how much you should weigh at 5’6, a healthy range for most adults is about 115–154 pounds, though muscle and health can shift that window.

For adults, match weight to height using the BMI 18.5–24.9 range to get a healthy weight range instead of a single target number.

Healthy weight in your 40s depends on height, waist size, and body composition; aim for BMI 18.5–24.9 and a waist under half your height.

For a height of 163 cm, a healthy weight for most adults sits roughly between 49 kg and 66 kg based on standard BMI ranges.
