Finding Your Size

Finding your size is easy!

There are two methods:

The easiest is with this free printable ring sizer (will open as PDF in new window):


The other method is to use a thin flexible measuring tape, such as those found in sewing kits, to measure your joints and then locate your US ring size using this conversion chart:

Size Chart

For any style swan neck, boutonnierre, single and double lateral support splints, and mallet support splints:

Measure right around the joint(s) you need the splint(s) for, ensuring that the measuring tape is overlapping as shown in the picture. If there's any issues such as nodes or swelling that cause a size variation, or for the larger PIP joints if there is a size difference; measure just above and just below the joint(s), select the larger size from the drop down menu, and provide both sizes in the notes when checking out. If your measurement comes out smaller than the sizing on the chart just select the smallest size from the drop down menu and put your actual measurement/size in the notes for me. This way I can customize the sizing during production for a perfect fit.

For thumb splints:

Measure the thumb IP joint (the upper knuckle, below the fingernail) as this is where the thumb is usually widest and we want to be sure you can get your splint on/off comfortably. For thumb splints I will also need your wrist size to ensure you receive the proper size chain bracelet to secure your splint.

For IP/MCP combination splints I will need the length of the inside your thumb, as shown in the picture. With your thumb slightly bent measure the distance between the creases in your thumb.

For MCP/CMC/wrist combination thumb splints I will need the distance from the web of your thumb to your the base of your hand as shown in the picture and the circumference of your wrist.

For hand MCP splints and triggering splints:

Measure around the base of the finger where a regular ring would sit.

For buddy splints:

Measure both the finger that needs to be buddied and the one next to it at the base where a regular ring would sit. For pinky fingers I will also need to know the offset, or distance from where a regular ring would sit on the pinky to where a regular ring would sit on the ring finger. This allows me to create the splint so that it will sit properly on both fingers where a regular ring should sit to provide the most comfortable support.

If you've been measured for Oval 8 or Siris SRS I can convert the sizing for you. Select the size you have from the drop down menu and add into the notes which company you were sized for so I'll know to convert them.

If you have complicated issues such as nodes, swelling or severe deviation that makes sizing difficult, please feel free to contact me and I'll be happy to help!
