A healthy weight for a 5'5" woman is approximately 111-150 lbs based on BMI guidelines. Multiple formulas suggest a midpoint around 128 lbs (BMI 21.3). Your ideal weight depends on muscle mass, bone structure, and body fat percentage.

Two people at 5'5" and 128 lbs can look very different depending on body fat percentage. Explore what each level looks like:
Healthy body fat ranges are the same regardless of height: 14-24% for men and 21-31% for women (ACE guidelines). Athletes are typically 6-13% (men) and 14-20% (women). At 5'5" and 128 lbs, maintaining a body fat in the fitness range would mean carrying approximately 96 lbs of lean mass.
At 5'5", a weight above 150 lbs puts you in the overweight BMI category (25+). However, this does not account for muscle mass. A better approach is measuring body fat percentage. For woman, body fat above 32% is classified as obese by the ACE.
At 5'5", a weight below 111 lbs puts you in the underweight BMI category (below 18.5). Being underweight can lead to nutrient deficiencies, weakened immunity, bone loss, and hormonal issues. If you are underweight, consult a healthcare provider and focus on nutrient-dense foods with adequate protein.
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 (150 lbs). Small-framed individuals may be healthy at the lower end (111 lbs).
