Find Your Perfect Ring Size
How to Measure Your Ring Size (Accurately!)
Don’t have a steel ring sizer? No problem. Here’s how you can measure your ring size at home using just a thread and a ruler — but accuracy matters, so follow the steps carefully.
🧵 What You’ll Need:
- A piece of thread or non-stretchy string (no wool)
- A millimeter ruler
- A pen or fine-point marker
📏 Steps:
-
Wrap the thread tightly around your finger
– Choose the broadest part of the finger you’ll wear the ring on (usually the knuckle).
– The thread should feel snug and slightly squeezing. -
Mark the exact point where the thread crosses
– Mark it while it’s still tightly wrapped on the finger. -
Measure the thread length
– Lay the thread flat.
– Use a ruler with millimeter markings.
– Read the exact number in mm. -
Calculate your ring size
– Use this formula:
Ring Size = circumference (in mm) – 41
🧠 Example:
- You measure 57 mm → Use 57 mm
- 57 – 41 = Ring Size 16
