Yes. People with larger bone structures (wider wrists, broader shoulders) naturally weigh more at the same height and body fat. The formulas above provide averages. If you have a large frame, you may be healthy at the upper end of the range (164 lbs). Small-framed individuals may be healthy at the lower end (122 lbs).
If you are above the healthy range, create a moderate calorie deficit of 500 cal/day for ~1 lb/week loss. If below, add a 300-500 calorie surplus. In both cases, prioritize protein (0.8-1g per lb body weight) and resistance training. Use our TDEE calculator to find your maintenance calories and our cutting or bulking guides for a structured plan.
A healthy weight for a 5'8" woman is approximately 122-164 lbs based on BMI guidelines (18.5-24.9). Multiple formulas (Robinson, Miller, Devine) suggest a midpoint around 140 lbs. However, ideal weight varies significantly based on muscle mass, bone structure, and body fat percentage.
A healthy BMI range is 18.5-24.9 regardless of height. For someone 5'8", this translates to 122-164 lbs. BMI is a rough screening tool and does not distinguish between muscle and fat. A muscular person may have a high BMI while being perfectly healthy.
