How to Measure Your Ring Size at Home

Measure your finger circumference in millimetres, then match it with the chart below to choose the right iTasbih Peace 1 ring size. You will need a thin paper strip or a soft measuring tape, a pen, and a ruler with millimetre marks.

Step 1 – Prepare your tools

Prepare a thin paper strip or a soft measuring tape, a pen for marking the overlap point, and a ruler with a millimetre scale.

Step 2 – Wrap around your finger

Wrap the strip around the finger you plan to wear the ring on. Keep it close to the skin, straight and level – snug, not squeezed.

Step 3 – Mark and measure

Mark the point where the strip overlaps, lay it flat and measure the length in millimetres. This is your finger circumference. Repeat 2–3 times and use the average result.

Step 4 – Match your size

Compare your finger circumference with the size chart and choose the size that best matches your measurement. If you are between two sizes, choose the larger size.

• #18 – 18.20 mm inner diameter, 57.15 mm circumference (US 8)

• #19 – 19.00 mm inner diameter, 59.66 mm circumference (US 9)

• #21 – 20.70 mm inner diameter, 65.00 mm circumference (US 11)

• #22 – 21.50 mm inner diameter, 67.51 mm circumference (US 12)

• #23 – 22.30 mm inner diameter, 70.02 mm circumference (US 13)

Note: if your measurement falls between two sizes, choose the larger size for a more comfortable daily wearing experience.

Important Measuring Tips

• 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.
