Frame Size (Elbow) Calculator

Use my elbow width to determine my frame size.

Since bone structure varies in size from person to person, researchers have added frame size as a factor in helping to determine someone’s ideal weight. Knowing your frame size can help you set reasonable weight goals. Enter your height and elbow width and this calculator will use standard insurance industry tables to show your frame size and ideal weight range. (Measuring the elbow, rather than the wrist, to determine frame size gives more range and accuracy, particularly for men.)

If you don’t have calipers, use your opposite thumb and index finger to find the two prominent bones of your bent elbow. Measure the distance between the thumb and index finger by carefully maintaining the distance and holding them against a tape measure or ruler.

  1. I agree with Jane’s question. Is it the width or the circumference of the elbow or to include the wrist also as width or circumfernce?

  2. Going by wrist sizes I’m a small frame. Going by this one I’m large? Wow. It’s saying I should be 25-45 pounds heavier then I am now…I had weight related health problems when I weighed that for a year and they all disappeared after I lost the weight! Anyway, this explains why I felt retarded when doing ballet (I noticed my arms didn’t look as elegant as everyone elses.

  3. To measure the wrist you measure the circumference of your wrist just above the bone.

    To measure the elbow you bend your forearm so that it’s 90 degrees or shaped like a capital “L”

    Put your forefinger and thumb on the bones on both sides of the underside of the “L”

    Measure the space between the thumb and forefinger with a ruler to get your elbow width
