Determine your frame size using the body frame size calculator. First select your gender. Then enter either your wrist size or elbow breadth. Lastly, enter your height in meters or feet and click calculate.
Determine your wrist size by measuring your wrist just below your wrist bone with a tape measure. This is the smallest point of the wrist.
To determine your elbow breath extend your arm forward such that it is horizontal and parallel to the ground. Then bend your elbow such that your forearm is at a 90º angle to the ground. Place your forefinger and thumb of your other hand on either side of your elbow joint. Then use your forefinger and thumb as a gauge to determine your elbow breadth by measuring the gap between them with a ruler.
Determining your frame size will help you set realistic weight loss goals (use the ideal weight calculator, which takes your frame size into account). We do not all have the same size of frame; some people have a smaller and lighter frame, while others will possess a heavier build. As such, if you have a large frame size you cannot expect to weigh the same as someone with a small frame.
This is a very rough method of determining frame size and is mostly about getting you to understand that we aren’t all built the same, can’t all look the same (even if we try), to help you set more realistic goals, to focus less on a number on a scale and focus more on having a healthy body composition. For example, this calculator determines frame size only from one measurement (upper body), it does not take the lower body into consideration. However, upper and lower body frame size is not necessarily the same. The upper body of a pear-shaped women for example may be small framed (delicate hands and wrist), while her lower body might be larger framed (heavier ankles).
Rating scales such as the body mass index, do not take the size of your frame into account, which means that is lacks accuracy in determining whether or not you fall within a healthy weight range. For example, a mesomorph tends to be medium or large framed and also carries a good amount of muscle mass. You can’t compare this persons weight when in shape with an out-of-shape ectomorph whose skeleton is slight and at the best of times carries little muscle mass.
