Things To Keep In Mind While Measuring You Finger Size

Time & Temperature :

Measuring the ring in cold or in hot temperature will affect the ring size measurement. Also checking the finger size at the end of the day when it is largest is strongly recommended.

Ring Width :

Wider rings feel tighter than thinner rings. Choose a half size bigger for ring widths that are 4.0 mm or more.

Comfortable but Secure :

Ensure that your ring is secure but can easily slide over your knuckle and feels comfortable at all times.

Shape of Finger :

If your knuckle size is larger than average please make sure you keep in mind the need for a slightly larger size to ensure comfort.

So, how do ring sizes work? Ring sizes have a scale of A to Z. A is the smallest size, and Z is the largest. Each letter represents the circumference of the ring in mm. Most jewellers offer half sizes so that you can get the most accurate and comfortable fit.
