Effortlessly use body frame size calculator to your skeletal frame structure from height and wrist circumference to categorize your body frame as small, medium, or large.
For Women:
- Height under 5’2″
- Small: < 5.5 inches wrist
- Medium: 5.5-5.75 inches
- Large: > 5.75 inches
For Men:
- Height over 6’0″
- Small: < 6.75 inches wrist
- Medium: 6.75-7.0 inches
- Large: > 7.0 inches

Body Frame Size Chart
| Height Range (feet) | Small Frame (inches) | Medium Frame (inches) | Large Frame (inches) |
|---|---|---|---|
| 4’10” – 5’2″ | < 5.5 | 5.5 – 5.75 | > 5.75 |
| 5’2″ – 5’5″ | < 6.0 | 6.0 – 6.25 | > 6.25 |
| 5’5″ – 5’9″ | < 6.25 | 6.25 – 6.5 | > 6.5 |
| 5’9″ – 6’0″ | < 6.5 | 6.5 – 6.75 | > 6.75 |
| Over 6’0″ | < 6.75 | 6.75 – 7.0 | > 7.0 |
Body Frame Size Formula
The body frame size use the following equation:
Frame Size = Height (cm) / Wrist Circumference (cm)The resulting ratio (Frame Size) indicates frame size according to the following ranges:
- Small Frame: R > 10.4
- Medium Frame: R = 9.6 – 10.4
- Large Frame: R < 9.6
For example…..
- Height: 170 cm
- Wrist Circumference: 16 cm
- Frame Size = 170/16 = 10.625
Interpretation:
- Less than 10.4 = Large Frame
- 10.4 to 11 = Medium Frame
- Greater than 11 = Small Frame
How do you tell if you are small, medium, or large boned?
Determining whether you are small, medium, or large-boned involves several key measurements and observations:
- Wrist Method: Wrap your thumb and middle finger around your wrist. If they:
- Overlap significantly = Small Frame
- Barely touch = Medium Frame
- Don’t meet = Large Frame
- Elbow Method: Extend your arm and bend your elbow at a right angle (90 degrees). If your fingers:
- Wrap around easily = Small Frame
- Just meet = Medium Frame
- Don’t touch = Large Frame
A person, standing at 5’11”, can barely touch his fingers when wrapping them around his wrist, indicating a medium frame size.
How do I measure my frame size?
To accurately measure your frame size:
- Stand straight with a relaxed posture.
- Use a flexible measuring tape.
- Measure key points:
- Wrist circumference
- Elbow breadth
- Ankle circumference
- Shoulder width
A female measures her wrist circumference at 5.75 inches, elbow breadth at 2.5 inches, and stands at 5’4″, indicating a small frame size.
How to measure wrist circumference?
To measure wrist circumference properly:
Position: Let your arm hang naturally.
Placement: Place measuring tape just below the wrist bone.
Tension: Keep tape snug but not tight.
Reading: Note measurement in inches or centimeters.
Mike measures his wrist by placing the tape measure just below his wrist bone, obtaining a measurement of 7.2 inches, indicating a large frame for his height of 6’2″.
What is considered a large frame for a man?
A man is considered to have a large frame when:
- Height over 5’5″: Wrist circumference > 6.5 inches
- Height over 5’9″: Wrist circumference > 6.75 inches
- Height over 6’0″: Wrist circumference > 7.0 inches
At 6’1″ with a wrist circumference of 7.2 inches, is classified as having a large frame.
