Step 2Wrap Around Your Finger

Wrap the paper strip around the finger where you plan to wear the ring. Keep it close to the skin, but not tight.

  • Measure the exact finger you will wear the ring on
  • Keep the strip straight and level
  • It should feel snug, not squeezed

Step 3Mark and Measure

Mark the point where the strip overlaps. Lay the strip flat and measure the length in millimeters.

  • The measured length is your finger circumference
  • Use millimeters for better accuracy
  • Repeat 2–3 times and use the average result

Important Measuring Tips

These tips help reduce measurement errors and make the final ring size more comfortable for daily wear.

Measure 2–3 times.
Repeat the same measuring process and use the average result for better accuracy.
Measure at the end of the day.
Fingers are usually closer to their normal daily size after daily activity.
Avoid cold hands.
Do not measure when your hands are very cold, because fingers may temporarily become smaller.
Check your knuckle.
If your knuckle is wider than the base of your finger, make sure the ring can pass over it comfortably.

Comfort Recommendation

iTasbih is designed for daily Dhikr and long-time wearing. The ring should feel secure on your finger but still be easy to remove. If you prefer a looser fit, choose one size larger.
