If you hover on the AR numbers on the weave pages, it will give you some ring sizes (Requires you having JavaScript turned on/allowed on MAIL)
You can change the measurement system it uses (gauge/mm/inch/etc) in your MyMAIL preferences.

Beyond that, you can figure it out yourself.
Take the Inner Diameter of your Rings
Divide that by the Diameter of your wire, and you get a Ratio we call Aspect Ratio (or AR)

So...
AR=ID/WD

You can reverse this, to find the right Inner Diameter to use with your rings by taking the AR number and multiplying it by the diameter of your wire.

So...

ID = AR * WD

If you use cheapy craft rings that measure in Outer Diameter (OD) you need to add 2xWD onto the final ID Measurement to compensate...

Hope that helps.

 Posted on Thu May 10, 2012 10:00 pm Link to Post: Zlosk wrote a pretty good article on aspect ratio: http://www.zlosk.com/maille/aspectratios.html And he has a chart listing what ARs work best with certain weaves: http://www.zlosk.com/maille/artable.html I have one too, link in signature. Once you have an idea of what AR to use, you would try and find ring sizes that come close. We can throw you some ideas of ring sizes to use if you let us know what specific designs you're interested in. Chainmailbasket.com (2018-03-30) - 270 + 24

 Posted on Sat May 12, 2012 8:27 am Link to Post: Psst Konstantin. 'Add to the ID', as written - but meant was surely subtract from OD' - Both is valid; it just depends on the work direction. Do you have the AR and want to know the craft shop ring OD? Or do you have the shop rings' OD, and want to have the AR... -ZiLi- Maille Code V2.0 T7.1 R5.6 Ep Fper MAl Ws\$ Cpbsw\$ G0.3-6.4 I1.0-30.0 N28.25 Ps Dacdejst Xagtw S08 Hip Human societies are like chain mail.
