How to Measure Circular Body Jewelry
How to Measure Circular Body Jewelry (The Right Way!)
If you've ever found yourself confused about how to measure a body jewelry ring, you're not alone! Understanding how to properly measure circular jewelry—especially for piercings like Septums or Daiths—can save you a ton of time, discomfort, and return hassles.
The Golden Rule: Only Measure the Inner Diameter
When you're measuring a circular body jewelry ring, do not include the ring itself in your measurement. We know it sounds a little silly at first, especially with thicker gauge rings—but trust us, this makes all the difference.
The diameter of body jewelry is measured in millimeters (mm) from the inner edge of one side to the inner edge directly across—this is the largest central space inside the ring. Think of it as measuring the space your piercing will actually occupy, not the total size of the ring.
Pro Tip: Use a caliper or a small ruler for the most accurate measurement!
Why It Matters
Measuring diameter is crucial. This small measurement can make a big impact on how your jewelry fits and feels. For example:
-
Typical Septum Rings usually range between 8mm – 10mm in diameter.
-
If you mistakenly purchase a 6mm ring, it might feel uncomfortably tight or not fit at all.
-
A ring that’s too large may slide or rotate too much, which can cause irritation.
Anatomy Matters
Each piercing placement has its own ideal sizing depending on your anatomy. While body jewelry can be interchangeable, that doesn’t always mean it should be.
Choosing the wrong size can lead to:
-
Sliding or twisting of the jewelry
-
Skin pinching
-
Irritation or Keloid formation from too much movement
Getting the correct diameter ensures your jewelry sits comfortably and safely in place—no shifting, no pinching, no regrets.
