To get the best fit possible I highly recommend heading down to your local jeweller to get sized. Ring sizing is universal so don’t worry if you don’t quite understand the sizing they give you. You want to avoid having to re-size a ring so getting it to fit perfectly the first time is best and you want to feel confident ordering online.
If you can’t do that then here is a tip, but its certainly not highly recommended.
Grab yourself a ruler and measure the internal diameter of one of your rings (one side to the other, internal) and match it up to a measurement on here or let me know the internal diameter. It needs to be fairly exact right down to the point of a mm.
