How to use Aspect Ratio
Ring sizes and converting them can easily cause confusion. Aspect ratio is the easy way out of the confusion.
AR is aspect ratio. It is the ratio of the ID divided by the wire diameter (AR=ID/wiredia)
Basically it tells you how fat the donut is. Some weaves require loose rings and some require tight (fat) rings. The weave samplers page tells you recommended AR's for some weaves.
I'll explain how to use them by giving an example of looking for a ring for a certain project that is a different guage.
We use standard wire gauge. A lot of other companies use American Wire gauge. If you need a ring that is their size 18g - this is 0.04" (1mm) - it is our 19g.
I recommend bypassing the gauge confusion and looking at the size in decimal inches or mm. This info is listed for every ring and highlighted in the following listing for you.
The actual inner diameter of the ring is also given in decimal inches or mm.
For more information of reading the information provided on the site see the How to Read the Site page.
Ok so now you've figured out what ring it is that you have. You've used this ring for a certain project and liked it but can't get 19g in copper and you'd like to try copper. You've decide 18g will be good.
Here's where you look at the AR. The AR for the ring you liked is listed in green
You can do one of 2 things next. You can go directly to the material you were interested in and the size you wanted and look for this AR. Or you can hit "Search by AR"
If you hit the search button you will be asked for a range. The range depends on the weave - you can always look again with a different range if too few rings pop up in your range.
What happens when the exact number doesn't come up? You have to decide will tighter be ok? Would looser be better? This depends on the weave and you.
