How Sizing Works for Splint Rings

Choosing the right size for a splint ring is key to comfort, support, and effectiveness. At Splints by Evabelle, we use standard ring sizes to make it simple for anyone to measure their fingers or thumbs accurately. Whether you measure at home, with a jeweler, or through your occupational therapist (OT), you can get the correct fit without guesswork.

Why Standard Ring Sizes Matter and How Sizing Works for Splint Rings

Using standard ring sizes means:

• Accessibility – Anyone can find their size using tools available online, in stores, or through their OT.

• Consistency – Standard sizes ensure that splints fit as intended across different designs and styles.

• Ease of ordering – You don’t need custom measurements for most splints; just your standard ring size.

  
  

How to Measure Your Finger or Thumb

There are three main ways to measure:

1. Visit a Jewelry Store – Jewelers can measure your finger quickly and accurately using professional ring sizers.

2. Use a Standard Ring Sizer at Home – These are affordable and available online or in craft/jewelry stores. They often come as a set of plastic or metal rings or as a measuring tape.

3. Ask Your Occupational Therapist – Many OTs have standard ring sizers and can help you measure accurately, especially if your finger has swelling or limited mobility.

Tip: Measure your finger at the end of the day when it’s slightly larger for the most accurate fit. Avoid measuring when your hands are cold, as fingers can shrink slightly.

Special Sizing Considerations by Splint Type

Different splints interact with joints differently, so sizing can vary:

Swan Splints & Mallet Finger Splints

• These splints typically pass over a joint, so they require two ring sizes: one above and one below the joint.

• Ensures the splint can slide on without pinching while keeping the joint supported.

• Check the product listing for recommended spacing and ring sizes specific to each splint style.

  
  

Thumb Splints

• Thumb splints come in multiple designs, some covering the full thumb, others supporting only a section.

• Depending on the style, you may need multiple sizes to accommodate the base, midsection, and tip of the thumb.

• Listings provide guidance on which parts of the splint require which sizes.

MCP, Trigger Finger, & Hyperextension Splints

• For these, the base joint ring size is critical.

• The splint may also require extension measurements to ensure proper finger alignment.

• This sizing ensures the splint supports the joint fully while allowing safe, controlled movement.

Tips for a Perfect Fit

• Always refer to the size chart provided in the listing.

• If you’re between sizes, sizing slightly larger is usually more comfortable.

• Consider swelling or stiffness – measure fingers at the same time of day if possible.

• For multi-joint splints, double-check that all rings fit comfortably to avoid pinching or slipping.
