Body Frame Size Calculator for Women (Wrist & Elbow)
Last reviewed: October 2026 by the Get Tips For Better Life Editorial Team
Body frame size describes how big your bones are: small, medium or large. It’s one reason two women of the same height can both be healthy at quite different weights.
This free body frame size calculator for women uses your wrist size (the method on MedlinePlus, from the U.S. National Library of Medicine), with an optional elbow check, and shows a healthy weight range for your frame. No sign-up, and nothing you enter is saved.
Body Frame Size Calculator for Women
Find out if you have a small, medium or large frame from your wrist size (and elbow, if you like), plus a healthy weight range for your frame.
Wrap a tape measure around the smallest part of your wrist, just above the wrist bone.
Bend your arm to 90°, palm facing you, and measure the width between the two bony points of your elbow.
Wrist method: MedlinePlus (U.S. National Library of Medicine) chart for women. Elbow method: 1983 Metropolitan Life tables for women. Ideal weight: Hamwi formula, adjusted 10% for small or large frames. These are rough guides, not medical advice.
Wrist Size Chart for Women
| Height | Small frame | Medium frame | Large frame |
|---|---|---|---|
| Under 5’2″ | Wrist under 5.5 in | 5.5 to 5.75 in | Over 5.75 in |
| 5’2″ to 5’5″ | Wrist under 6 in | 6 to 6.25 in | Over 6.25 in |
| Over 5’5″ | Wrist under 6.25 in | 6.25 to 6.5 in | Over 6.5 in |

How to Measure Your Wrist
- Use a soft tape measure (or a strip of paper you then measure with a ruler).
- Wrap it around the smallest part of your wrist, just above the wrist bone, on the side of your hand.
- Keep it snug but not tight, and read the number in inches or centimeters.
Quick check without a tape: wrap your thumb and middle finger around your opposite wrist. If they overlap, you probably have a small frame. If they just touch, medium. If they don’t meet, large. It’s rough, but useful.
Elbow Breadth Method (Optional)
Bend your arm to 90° with your palm facing you. Feel the two bony points on either side of your elbow and measure the distance between them (calipers are best, or pinch your fingers on the points and measure the gap).
| Height (women) | Medium frame elbow breadth |
|---|---|
| 4’10” to 5’3″ | 2¼ to 2½ in |
| 5’4″ to 5’11” | 2⅜ to 2⅝ in |
| 6’0″ and over | 2½ to 2¾ in |
Smaller than the medium range means a small frame, and larger means a large frame. Source: 1983 Metropolitan Life tables (heights measured in 1-inch heels).
Height-to-Wrist Ratio
Some calculators divide height by wrist size instead (both in the same unit). For women, a ratio over 11 suggests a small frame, 10.1 to 11 medium, and under 10.1 large. Our calculator shows this too. It’s a different method, so it can disagree with the chart, especially near a cut-off. When two methods agree, that’s your most likely frame.
Ideal Weight by Frame Size for Women
These ranges use the Hamwi formula (100 lb at 5 feet, plus 5 lb for each inch above), lowered 10% for a small frame and raised 10% for a large frame. We never go below a healthy BMI of 18.5.
| Height | Small frame | Medium frame | Large frame |
|---|---|---|---|
| 4’10” | 89 to 94 lb | 90 to 100 lb | 99 to 110 lb |
| 5’0″ | 95 to 100 lb | 95 to 105 lb | 105 to 116 lb |
| 5’2″ | 101 to 106 lb | 104 to 116 lb | 115 to 127 lb |
| 5’4″ | 108 to 113 lb | 114 to 126 lb | 125 to 139 lb |
| 5’6″ | 115 to 123 lb | 124 to 136 lb | 136 to 150 lb |
| 5’8″ | 122 to 132 lb | 133 to 147 lb | 146 to 162 lb |
| 5’10” | 129 to 142 lb | 142 to 158 lb | 157 to 173 lb |
| 6’0″ | 137 to 151 lb | 152 to 168 lb | 167 to 185 lb |
These “ideal” weights are on the low side for many women, especially after 40. The healthy BMI range (18.5 to 24.9) is wider, and both are only guides. Compare more formulas with our ideal weight calculator for women.
Does Frame Size Matter for BMI?
BMI doesn’t consider frame size. A woman with a large frame may have a slightly higher BMI without carrying extra fat, while a small-framed woman can have a “normal” BMI with more body fat than ideal. That’s why waist size and body fat are useful extra checks. Try the waist-to-hip ratio calculator and the body fat calculator for women.
Frequently Asked Questions
How do I know my body frame size as a woman?
Measure your wrist and compare it with the chart for your height. Under 5’2″, a wrist under 5.5 inches is a small frame. From 5’2″ to 5’5″, under 6 inches is small. Over 5’5″, under 6.25 inches is small.
What is a medium frame for a woman who is 5’4″?
A wrist between 6 and 6.25 inches.
Should I measure my dominant wrist?
Most guides don’t specify. Measure the wrist you don’t write with, and use the same one each time.
Does frame size change with age?
Bone size doesn’t change much in adulthood, but bone density can drop after menopause. Frame size is about bone width, not density.
Is there an ideal weight for my frame?
Formulas give a rough target, but a healthy weight is a range. Strength, waist size, and how you feel matter more than hitting one number.
What does it mean if my fingers overlap around my wrist?
It usually means a small frame. If they just touch, it’s likely medium.
Is a 6-inch wrist small for a woman?
It depends on your height. Under 5’2″, a 6-inch wrist is a large frame. From 5’2″ to 5’5″, it’s medium. Over 5’5″, it’s small.
Can I use the calculator in centimeters?
Yes. Tap Metric and enter your height and wrist in centimeters. The chart thresholds switch to centimeters too.
