Stacking Ring Size Guide

When determining your ring size, keep in mind that your finger size can expand and shrink due to temperature changes, eating certain foods, or doing certain activities with your hands. When it comes to temperature change, your fingers are typically bigger in the morning or when you're hot. On the other hand, your fingers shrink when you are cold. So be sure to measure your ring size in a few situations to help you pick your size.

Example: My index finger is usually a US 6. But when it's cold, my index finger can drop to a US 5. And when it's hot or my fingers are swollen my index finger can go up to a US 7.

Method #1: Measure the diameter of an existing ring 

  1. Pick an existing ring that fits the desired finger.
  2. Measure the internal diameter of the existing ring in millimeters. 
  3. Match the measurement to the closest number on the below chart to find your approximate ring size.
US Ring Size Ring Internal Diameter (mm)
4 14.9
5 15.7
6 16.5
7 17.3
8 18.1
9 19
10 19.8
11 20.6
12 21.4

 

Method #2: Measure the circumference of your own finger 

  1. Wrap a length of (non-stretchy) string/ribbon/paper around the desired finger. Make sure to pull it so it's a snug fit.
  2. Measure the length of the string/ribbon/paper in millimeters.
  3. Match the measurement to the closest number on the below chart to find your approximate ring size.
US Ring Size Finger Circumference (mm)
4 46.8
5 49.3
6 51.9
7 54.4
8 57
9 59.5
10 62.1
11 64.6
12 67.2

Adjustable EDS Ring Splint Size Equivalents

To choose the correct size for your EDS ring splint, use a standard ring sizer (or use Method #2 above) and measure around your knuckle. The fit should be snug but not tight.

If you already have EDS rings, use the chart below as a guide to find the approximate EDS ring splint size. 

Adjustable Ring Splint Size EDS Ring Splint Size Equivalent
4 5.5-6.5
5 6.5-7.5
6 7.5-8.5
7 8.5-9.5
8 9.5-10.5
9 11-12
10 12-13
11 13-14
12 14-15

How to adjust your splint ring

Artist disclaimer: This ring splint is wearable art, not a medical device, and is not a replacement for professionally prescribed medical splints or care.

With three points of refined adjustments to accommodate the changing needs of your hands, this swan neck splint ring is for everyone whether or not you live with Ehlers-Danlos Syndrome (EDS). 

Adjusting the outer rings

Changing the angle of the outermost rings will loosen or tighten the fit of the splint. 

How to make the splint fit looser / tighter 

To loosen the fit, evenly push the outermost ring inward.

To tighten the fit, evenly pull the outermost ring outward. If needed, you can also slightly expand or compress the outer rings themselves to refine the fit.

If needed, you can also slightly expand or compress the outer rings themselves to refine the fit.

Always apply slow, even pressure. Avoid aggressively forcing the metal. Gradual adjustments will help preserve both the fit and the integrity of your splint.

Adjusting the center (width & circumference)

Changing the center section alters the overall width and circumference of the splint. 

Note: If you’ve already adjusted the outer rings, you may need to refine them again after this step.

How to increase or decrease the circumference of the splint

Wrap a ring mandrel (or other tapered tool) with a soft cloth to prevent scratches.

To increase size: gently slide the splint down the mandrel and check the fit in between each gradual adjustment.

To decrease size: place the splint on the mandrel at a slightly smaller section and carefully press the sides inward.

Always apply slow, even pressure. Avoid aggressively forcing the metal. Gradual adjustments will help preserve both the fit and the integrity of your splint.
