Sizing Information

Choosing Your Sling Ring Size

When you are making a sling, choose your Sling Ring based on the following four criteria:

  • the weight/texture (aka "hand") of the fabric
  • the width of the fabric
  • the shoulder style of the sling
  • your personal preference for the balance between security and ease of adjustment.

(Note: Your child's weight and height have nothing to do with which size Sling Ring you need. Each and every ring is put through a pull test to 250lb.)

Small: Small Sling Rings are best used with light weight, and/or very smooth fabrics. They are also well-suited to closed tail slings and onbuhimos. If you plan to make your sling very narrow (22"-26") you might also want the small Sling Rings. Smaller rings tend to be very secure, though not as easy to adjust as the larger rings.

Medium: If you are using a medium weight fabric, in widths of 26 "-30", you might be more comfortable with the medium size rings. In general, the medium Sling Rings will give you a sling that is secure, but may not be as easy to adjust as the large rings if your fabric is on the thicker side. Many people prefer medium rings when making a single-layer dupioni or shantung silk sling, especially if it will be machine-washed.

Large: This is by far the most popular size of Sling Ring available. This is the size you'll want if you are looking to incorporate Sling Rings into your woven wrap tie-offs or for DIY Wrap Conversion Ring Slings (WCRS). If you are using a heavy weight (winter weight) or heavy nap fabric, a very wide fabric (30"-45"), or have just had difficulty adjusting your sling in the past even if it is a thinner fabric, you may want to try large Sling Rings. They are also preferred for double-layered slings of nearly any material.

Extra Large: This is a new in 2017 size offered by SlingRings.com. The extra large size aluminum rings might be perfect for you if you have a particularly luxurious hand-woven, and you're looking for tie-off options or converting a very cushy woven wrap into a Ring Sling. If you are using a heavy weight (winter weight) or heavy nap fabric, and you're making a double-layered sling, you may want to try the Extra Large size.


For the record, my absolute favourite source for DIY ring sling tutorials is Sleeping Baby Productions; I consider myself an "intermediate beginner" with my Singer FashionMate from Canadian Tire - nothing very fancy - and I have had no problems making WCRS for myself and as gifts using her tutorials. No matter which pattern you are using, you will want to carefully test your ring/fabric combination to make sure that your sling will be safe. A sling is a very simple concept, but the wrong combination of rings and fabric can be dangerous. Always practice safe baby carrying.

Please feel free to personally contact me if you are still not sure what size is appropriate for your application.
