For the iTasbih Peace 1, choose your size by matching your finger circumference or a well-fitting ring's inside diameter to the chart below. The Peace 1 size label is not its exact diameter in millimetres. For example, size 19 measures 18.90 mm across the inside and corresponds to US size 9.
At Zovqo, we want your zikr ring to feel comfortable while you count. Start with the exact model you want, then check its sizing system. Peace 1 uses fixed size options; other tasbih rings may come with interchangeable bands.

Ordering tip: our product selector may show a label such as “19mm”. Use the Peace 1 size 19 row above: its actual inside diameter is 18.90 mm. Likewise, size 20 is 19.80 mm and size 22 is 21.40 mm. Check the colour and available option on our iTasbih Peace 1 product page before ordering.
How to measure a ring that already fits
- Choose a ring that fits comfortably on the same finger you plan to wear your Peace 1.
- Place it flat and measure straight across the centre of the inside opening. Do not include the ring's edges.
- Record the inside diameter in millimetres.
- Compare your measurement with the inside-diameter column for your preferred colour.
For example, an inside diameter close to 19.80 mm points to Peace 1 size 20 in matte black. It does not mean US size 20.
How to measure your finger with a paper strip
- Wrap a narrow paper strip around the finger where you will wear the ring. Keep it flat and comfortably snug.
- Mark where the strip overlaps.
- Lay it flat and measure from the start to the mark in millimetres. This is your finger circumference.
- Repeat the measurement to check it, then compare it with the circumference column above.
- Allow for the ring to pass comfortably over your knuckle. If your measurement falls between sizes or your knuckle is noticeably wider, ask us for help before ordering.
A paper measurement is approximate. Do not pull the strip tight or assume the nearest size will suit every finger. A ring should feel secure without pinching and should come off without force.
Fixed-size rings and interchangeable bands
Peace 1 is ordered in a selected colour and size. You need to choose the fit before buying; the chart above applies specifically to Peace 1.
Some of our other zikr rings offer multiple interchangeable bands or shells. That gives you more fitting options in one package, but it does not guarantee a fit for every finger. Check the exact model and included band sizes rather than applying the Peace 1 chart to another ring.
- Zikr Flex Pro: explore the included size options on its product page.
- Zikr Ring Jood: check its interchangeable shell options.
- Faith Smart Tasbih Ring: compare its five-size package.
- Equantu SQ976: check its five interchangeable band options.
For other fixed-size models, including Salam SQ666, use that model's own size information. A Peace 1 label, a US size and a measurement in millimetres are not interchangeable.
Buying a zikr ring as a gift
If you are choosing Peace 1 for someone else, measure a ring they wear on the intended finger or ask for their measurement. If you cannot obtain it, an interchangeable-band model may offer more flexibility, provided the included range suits the recipient.
Check our return and exchange policy before ordering. Contact us about sizing questions; exchanges depend on the policy conditions and stock.
