Once you have a ring in hand, put it on (see our how to, if needed) and do an easy test before things get hard. Hopefully, you are using one or more of our Sizing Rings which are cheap and recyclable, start with the largest and work your way down. You can even use one of our paper rings but this is not as easy.
With ring snugly in place on your flaccid package, hook your index finger under the edge of the ring and work it between you and the band all the way up to, but not including, your second knuckle (this should be pretty easy and not require any lube). That’s the one finger test. Start over for the 2 and 3 finger tests, they work the same way. What is your max finger count?
0 FINGERS: Remove the ring immediately! How did you even get it on? At some point, you ignored a voice in your head screaming something about self preservation. You really should listen to those voices.
1 FINGER: Tight fit and will result in aggressive restriction of blood flow during erection. Things will get purple, perhaps uncomfortable, and you may be required to ejaculate to lose the erection (which will happen slowly). In terms of hardness, this ring size will give you the maximum effect but at the possible expense of your own pleasure. Do not wear a ring of this size while erect for very long!
2 FINGERS: Goldilocks. Firm fit and will result in moderate restriction of blood flow. This ring size will give your erection a gentle but noticeable boost; harder and more persistent. There may be some discoloration, this is normal, and the state of your erection will follow your state of arousal. It is the opinion of King Rings’ staff that 2 Fingers is the ideal fit.
3 FINGERS: Loose fit and easier to put on and remove. You will look and feel great wearing a King Ring this size but it may not give your erection much benefit. Super comfortable when erect, lifts your balls up and away from your body (as do all our rings), and without much or any discoloration. Our Tungsten Carbide rings can weigh more than 11oz / 312g and, when worn casually, a 3 Finger size may work its way off your package and then down and out your pant leg. In other words, an excellent conversation starter.
DISCLAIMER: Every man is unique in shape, size, and volume change of erectile tissue. The Three Finger Rule Of Thumb is a great guide for many men but may not be right for everyone. Use your good judgement and listen to the voices in your head, you are solely responsible for you. Have fun!
