Aspect Ratio is the Ratio (value) between a jump rings wire thickness or gauge (GA) and its Inside Diameter (I.D), example for SX-AA-16516 with an ID of 0.325" and a Wire OD: 0.0625 the AR would be 0.325/0.0625=5.2 AR. Aspect Ratio is ratio used to to compare rings and to figure out what ring will work for what weave. To use AR select a weave using the M.A.I.L. link below and note the necessary AR. Then on TheRingLord.com the AR is listed in the Product Description of the rings you will use for your weave.

We have a few resources to assist you - click any of the below for more info.

• For basic ring size info, we have a chart you can print life size.
• The weave samplers page tells you recommended AR's for some weaves  M.A.I.L. - Maille Artisans International League - Weave Index .

Most weaves do not require the ring size to be precise! If you have a weave that you determine needs and AR of 5.3 but the ring on our site is AR 5.5 in most cases this is perfectly acceptable and it will work well. If you are deciding between 2 rings, you have to decide will tighter be ok or would looser be better? This depends on the weave and you. Tighter can be used but it depends on your experience with the weave - beginners tend to have more trouble closing rings in tight weaves. You can get a ring too tight. Most weaves work well enough in a range of about +/-0.3 on the AR. You can confirm by looking at the weaves samples page and seeing the recommended sizes. There are links at the top of that page as well for more resources on weaves and AR.
