Finding your perfect ring size has never been easier! With our Digital Ring Sizer, you can measure your size from the comfort of your home in just two simple steps.
To ensure accuracy, you’ll need to calibrate your screen.
Using a Credit Card: Align the top of your card with the dotted guide on the screen. Adjust with the plus (+) and minus (–) buttons until the bottom line matches your card’s bottom.
Using a Ruler: Place your ruler on the screen. Align the “0” on your ruler with the “0” on the screen. Adjust until the ruler measurements match perfectly.
Place an existing ring flat against the digital grid.
Adjust the scale with the plus (+) and minus (–) buttons until the circle on-screen touches the inner edges of your ring.
Once aligned, the tool will display your exact ring size.

Q1. Why do you only recommend up to 2 sizes for alterations?
Resizing more than 2 sizes can compromise the ring’s structure, especially if it has diamonds or intricate settings.
Q2. Can my ring be resized in the future?
Yes, most rings (except full eternity rings) can be resized. At Zarna Jewels, we offer one free resizing within 30 days of purchase (conditions apply).
Q3. What if my ring cannot be resized?
Some designs (like full eternity bands or delicate custom styles) cannot be resized. In such cases, we may need to remake the ring. Our team will guide you.
Q4. How long does resizing take? Can it be done in-store?
Resizing typically takes 10–14 working days. For in-person service, you may book an appointment at our Surat or Mumbai office.
Q5. Can I resize my ring multiple times without affecting it?
Yes, but we recommend limiting resizing as frequent alterations can weaken the metal and setting.
