Size Guide
Choosing the right size ensures the best comfort and accurate tracking. Use the steps below to find your size before ordering.
Method 1: Measure an existing ring (Most accurate)
Take a ring that fits the finger you’ll wear Vortex Pulse on.
Place it on a ruler.
Measure the inner diameter (straight across the inside of the ring).
Match your measurement to the size chart below.
Tip: If your size is between two options, choose the larger size for comfort.
Method 2: Measure your finger with paper or thread
Cut a thin strip of paper or use a thread.
Wrap it around the finger where you’ll wear the ring (snug, not tight).
Mark the point where the paper/thread meets.
Lay it flat and measure the length in mm this is your finger circumference.
Match the circumference to the size chart above.
Tips for best accuracy
Measure at the end of the day (fingers can be slightly larger).
Don’t pull the paper/thread too tight.
Measure 2–3 times and use the most consistent result.
If your knuckle is larger than your finger base, measure both and choose a size that passes comfortably.
Use the table to select your order size.
Inner Diameter (mm) = inside width of the ring
Perimeter (mm) = finger circumference
