For a 5’7″ female, a healthy weight range is generally between 121 and 153 pounds. This is based on the Body Mass Index (BMI) scale, where a BMI of 18.5 to 24.9 is considered normal. However, this is just a starting point, and the right weight for you depends on muscle mass, bone density, and overall body composition.
What Does the BMI Scale Say for a 5’7″ Woman?
The BMI scale is the most common tool doctors use. For someone who is 5’7″, a BMI of 18.5 equals about 118 pounds. A BMI of 24.9 equals about 153 pounds. The CDC officially recognizes this 118 to 153-pound range as “normal weight.”
Anything below 118 pounds is considered underweight. Anything above 153 pounds falls into the overweight or obese categories. These numbers come from population studies linking BMI ranges to health risks like heart disease and diabetes.
It is important to know that BMI does not measure fat directly. It is a calculation of height versus weight. A muscular woman might have a BMI over 25 but have very little body fat. The scale is a useful screening tool, not a perfect diagnosis.
What Is a Healthy Weight for a 5’7″ Female Based on Body Composition?
Body composition matters more than the number on the scale. Two women at 5’7″ and 145 pounds can look completely different. One might have 30% body fat, while the other has 20%.
Healthy body fat percentages for women range from about 21% to 33%, depending on age. A woman with more muscle will weigh more but carry less fat. This is why waist circumference is often a better health marker than weight alone.
The National Institutes of Health suggests that a waist size over 35 inches for women signals higher health risk. You can be 140 pounds with a 28-inch waist and be healthier than someone who is 130 pounds with a 36-inch waist. Focus on waist measurement and muscle mass, not just pounds.
How Age Changes Healthy Weight Ranges
Your healthy weight at 25 is not the same as at 55. As women age, muscle mass naturally decreases and body fat increases. This happens even if your weight stays the same.
Research published in the American Journal of Clinical Nutrition found that BMI standards may be too strict for older adults. A slightly higher BMI (24 to 27) is sometimes linked to better health outcomes in women over 60. This is called the “obesity paradox.”
For a 5’7″ woman in her 20s and 30s, staying closer to 125-140 pounds might be ideal. For women over 50, 140-155 pounds may be perfectly healthy if muscle mass is maintained. The key is preserving muscle through strength training, not chasing a number from your 20s.
| Age Group | Suggested Weight Range (5’7″) | Key Consideration |
|---|---|---|
| 20-39 | 121-150 lbs | Lower end often healthier if active |
| 40-59 | 125-155 lbs | Muscle loss begins; focus on strength |
| 60+ | 130-160 lbs | Slightly higher BMI may be protective |
Do Frame Size and Genetics Matter?
Yes, they do. Wrist circumference is a rough measure of frame size. A 5’7″ woman with a small frame (wrist under 6 inches) will likely be healthier at the lower end of the BMI range. A woman with a large frame (wrist over 6.5 inches) may be perfectly healthy at 155 pounds.
Genetics influence where your body stores fat. Some women carry weight in their hips and thighs, which is less risky than belly fat. Others store fat around the abdomen, which increases risks for metabolic disease regardless of total weight.
A 2019 study in JAMA Network Open found that normal-weight women with high belly fat had higher death rates than overweight women with low belly fat. This means two women at the same height and weight can have very different health profiles. Your family history and fat distribution matter more than a generic chart.
What to Avoid When Setting a Weight Goal
Do not chase a weight that requires extreme dieting. Many online charts suggest a “model weight” of 110-120 pounds for 5’7″. That is underweight for most women and can cause hormonal issues, bone loss, and low energy.
Avoid comparing yourself to social media influencers. They often use lighting, angles, and editing. Many also have low body fat percentages that are not sustainable long-term without strict dieting or performance-enhancing drugs.
Do not rely solely on BMI if you are athletic. If you exercise regularly and have visible muscle definition, your healthy weight may be 10-15 pounds higher than the BMI chart suggests. Use a body fat scale or a DEXA scan for a more accurate picture.
Avoid crash diets that promise rapid weight loss. Losing more than 1-2 pounds per week usually means losing muscle and water, not fat. This slows your metabolism and makes it harder to maintain a healthy weight later.
- Ignore “one size fits all” charts — they do not account for muscle or frame size.
- Do not aim for the lowest possible weight — being underweight carries its own health risks.
- Avoid waist trainers or detox teas — they do not change body composition.
- Do not skip meals to hit a number — this backfires by slowing metabolism.
What Does Research on Healthy Weight for 5’7″ Women Show?
Large population studies show that the lowest mortality risk for women of average height falls within the BMI range of 20 to 24. For a 5’7″ woman, that translates to roughly 128 to 150 pounds. This is not a strict rule, but a statistical trend.
A 2023 analysis in The Lancet looked at data from over 10 million people. It found that BMI between 20 and 25 was associated with the lowest rates of heart disease and diabetes. Below 18.5 and above 30, risks increased significantly.
Some studies suggest that being slightly overweight (BMI 25-27) in older age is less harmful than being underweight. The evidence is mixed, but the general consensus is clear: extreme ends of the weight spectrum carry higher health risks. The middle range is the safest bet for most women.
Frequently Asked Questions
Is 140 pounds healthy for a 5’7″ female?
Yes, 140 pounds falls within the healthy BMI range of 18.5 to 24.9 for a 5’7″ woman. It is considered a normal and healthy weight for most women of this height.
What is the ideal weight for a 5’7″ woman over 50?
For women over 50, a weight between 130 and 155 pounds is often healthy, with a slightly higher BMI sometimes being protective. Maintaining muscle mass is more important than the exact number.
Can you be 160 pounds and healthy at 5’7″?
It depends on body composition. 160 pounds puts a 5’7″ woman at a BMI of 25.1, which is technically overweight. However, if you have high muscle mass and low body fat, it can still be healthy.
How do I calculate my healthy weight if I have a large frame?
Add 10% to the standard BMI range. For a 5’7″ woman with a large frame, a healthy weight might extend up to 168 pounds. Use waist circumference and body fat percentage for a better assessment.
