For size, if you have a current hoop you can measure the diameter in 2 or 3 places and take the average to get your hoop size. Note, our hoop sizes are given in inside diameter (ID), which is the measure from inside edge to inside edge.
Size is largely personal preference depending on the kind of moves you're wanting to do but in general, a hoop with an inner diameter of around 26-28 inches is usually a great choice for off body hoop dance and 30+ inches is better for on-body moves.
The larger the size hoop, the easier it is to hoop around the body. Smaller hoops are better for more advanced tricks and off body hooping. It's common when starting out hooping to start with a larger size, then work down to smaller sizes as skill level increases. Please see the attached chart for more info.
We offer resizing service for our Atomic LED hoops. This way if you want to start a little larger and downsize later you don't have to get a whole new hoop. You also have 60 days after receiving your hoop to exchange it for a different size. So if it doesn't feel just right after trying it for a bit, you can send it in for a different one for just the price of shipping.
