Frame Size Guide

Working out your frame size can be tricky and is often inaccurate – we are all different shapes and sizes, and the only way to know for sure is to get a full body scan! It’s also true that as you lose weight, your wrist circumference could change significantly, so this should be used as a rough indication only.

However, having a general idea of your frame size or build can be useful when using weight loss calculators, as you will be able to adjust the results.

Method 1

To get a rough idea of your body frame size, just circle the thinnest part of your wrist with your thumb and fingers. If your thumb and fingers don’t touch, you have a large frame. If they only just touch, you have an average frame. If they overlap, you have a small frame.

However, this isn’t a very accurate measure – you might just have longer or shorter than average fingers! A slightly more accurate impression can be gained from measuring your wrist circumference.

Method 2

Wrist circumference should be measured using a soft tape-measure. Measure at the wrist crease, the area between the bottom of your palm, and your wrist bone. Compare the measurement to the table below.

Women:

Height under 5’2″

Small frame = wrist size less than 5.5″
Medium frame = wrist size 5.5″ to 5.75″
Large frame = wrist size over 5.75″

Height 5’2″ to 5′ 5″

Small frame = wrist size less than 6″
Medium frame = wrist size 6″ to 6.25″
Large frame = wrist size over 6.25″

Height over 5′ 5″

Small frame = wrist size less than 6.25″
Medium frame = wrist size 6.25″ to 6.5″
Large frame = wrist size over 6.5″

Men:

All Heights

Small frame = wrist size 5.5″ to 6.5″
Medium frame = wrist size 6.5″ to 7.5″
Large frame = wrist size over 7.5″

    1. Thanks for your comment – I did some research to try and find reliable information on calculating frame size for men under 5’5″, but it turns out that I’d actually made a mistake when I first wrote the page! The information I was able to find indicates that the wrist measurements given are applicable to all men – I’d just typed the header incorrectly. Please accept my apologies for the mistake – I’ve now updated the page.

      Interestingly, I wasn’t able to find anything more detailed on frame size for guys, but I will check periodically and update here as soon as any reliable information on this is made available.

    1. Hi Ron, “frame size” is really to do with your body shape and bone structure – e.g. someone who is petite could be said to have a small frame. It’s relevant here because if you have a small frame your ideal weight may be lower than someone with an average frame, likewise if you have a large frame you may be happier at a higher weight than the “ideal” indicated by the BMI system. Hope this helps!
