The interior diameter of the center ring will not be a true indicator of the size that will be effective for you because of the stretch, or give, of the ring.  Two men of the same exact size girth (fully erect) may use two completely different size support rings because each may need a different level of pressure applied to effectively maintain an erection. If you have never used a support ring and are not sure which size to try, you may guess and exchange sizes if the size you chose is incorrect, otherwise, we suggest that you purchase a Rejoyn ring kit which includes three (3) sizes of the Pos-T-Vac Ultimate ll support rings sizes l, ll, and lll .  This is a great way to try several sizes before ordering other types of rings. If you purchased a vacuum therapy system, or pump, from us you would have received three (3) Pos-T-Vac support rings, and should be able to chose a size based on these.
