US to UK ring sizes - which site to believe?

[Susie]

I've had an order from Spain for a ring, size US 7.5
I initially thought this would be an O due to a site i found, but i've since found a few more. One says it's a P, another O1/2.

Mmmm. I don't want to get this wrong, so I am asking the experts.
Is there one conversion you all trust?

Thank you so much

Sue

Why not send them a disposable ring sizer?

I send them to all my customers and amazingly haven't had a wrong size yet out of several hundred, even with wide rings , Im really impressed!

[Susie]

That's a good idea. Have you got a good source of ring sizers?

A link should have come up in my post above?
Its showing for me :)

Or, if you both have smart phones, both use the same ring sizer app. If you both use the same app it should be okay

Same as Sarah - I send the sizers out and no problems. Conversion site I use is this:http://www.ringsizes.co/

I have both sizes of mandrels UK- Europe (Which we use in Australia) and USA makes converting very simple, however I also use the above mentioned ring sizers if I am unable to fit personally as most people think they know their ring size but usually have no idea.

I went back and noticed your link Sarah, so ordered some from Cooksons. And Lydia, yes, that was the site i normally used, but then started to browse.
Thanks very much for your help everyone :0)
