I measured around the bicep, I have short arms so I knew they would be longer but the large fits well, offers good compression without cutting off circulation.

I have a 15" bicep and a 34" length. The large fits great! Hopefully you can use this info to help you figure out your size.

I suggest measuring your arm where you will wear it. I wear mine on my upper arm.S/M fits 8.5"-11". M/L fits 11"-15". For people with larger arms, there is an extender that adds 3", according to Sporteer website 15"-18".

The unit's opening roughly measures 16" circumference. You'd have to compare that with the circumference of your arm.

I found the info on their USA website--I'm not sure if this link will work as Amazon tends to delete, but google the name, choose the US site, pick the epitrain and it gives an illustration ( http://www.bauerfeindusa.com/en/products/supports-orthoses/elbow/epitrain.html ) Basically you measure 4 and 3/4 inches from the point of your elbow and take a circumference around your arm. The measurement then corresponds to a size. These fit snug, but that is the point. Oh, and in case Amazon deletes my link..the site is bauerfeindsusa dot com and then finding it is easy.

Measure your wrist, bicep (at thickest parts) as well as length from wrist to bicep. I did not measure the bent elbow but if you're wondering it measures a little under 12". I ordered large and my bicep measured 13", wrist 7&1/2" and length 17". It has a good stretch, if you're a little larger, yet maintains great compression. I really love them, surprised at how well they work.

You measure the width of your upper palm. Mine was 4 Inches, so I ordered a medium and it fits perfectly.

You use a dollar bill to measure. I pretty much knew already I was a small because my arms are so thin but the dollar test confirmed it. I believe the measurement method is in their website.

The 2XU website has a sizing chart for this and clearly states: "Measurements for the arm sleeves should be taken in a relaxed state at the largest girth of the bicep and the forearm. If your measurements of two different points for a garment do not correlate for one particular size, first try the size recommended by your forearm measurement."So NOT flexed. The other answer is just wrong.

I had returned it. The armband was bigger than my arm. You should measure your arm and compare it to the band's.
