How to Measure Your Ring Size

You know which ring is the right one for you, but are unsure about the right size? Here is how to measure your ring size.

A perfectly fit ring should not come off easily when you ease it on your finger, it should rather slide smoothly. This is important both for your comfort and to minimize the risk of loss.

  • If you are unsure about your ring size, the easiest way is to use our ring size guide . Just download and print our guide and find a ring that you wear comfortably on the same finger that you are buying your new Whitmore ring for. Place the ring on the chart to find the right size.

If you would rather measure at home, here are the steps to follow:

Cut a strip of paper or string no wider than 1/2" (1.4 cm).

Wrap it around the very base of your finger that you are planning to wear the ring on.

Use a pen to mark the point where it forms a complete circle and overlaps.

You can refer to the chart given below to convert the measured size into the US one, and then continue browsing your collection to find the perfect ring for you or your loved ones.

Whitmore tips for a sound measurement:

  • The size of your fingers will change with temperature and throughout the day. They expand in warm weather and shrink in cold. So, don’t measure your fingers when you are cold; they are the smallest at this time. Measure your finger at the very end of the day in warm temperatures when it is the largest for a more accurate reading.
  • If you're wondering how to measure your ring size, start by using a soft measuring tape or a piece of string to wrap around your finger and compare it to a sizing chart.
  • If you're unsure how you can tell what size ring you are, measure your ring size more than once before your purchase. Your left hand and right hand are not the same size. So, make sure to measure the finger you plan to wear the ring on.
  • If your knuckles are larger, take two measurements: one around the knuckle and one where the ring would go. Then, choose a size in between. Your ring needs to fit over the knuckle but not be too loose on the finger.
  • Consider the width of the ring you are planning to purchase. If it is wide, go for a 0.5 larger size. A ring sizing guide can be helpful in ensuring accuracy.
  • If you are hovering between two sizes, pick the larger one.

What if the the ring doesn't fit?

If your ring does not quite fit, don't worry. It's tricky to get the right size sometimes, but we've got you covered. Just return the ring for resizing if necessary to get a perfect fit.

We offer free resizing up to two sizes smaller or larger than ordered within 30 days of delivery. If the resize is more than two sizes, it is $90. Please note scalability based on the design's complexity; not all features scale. If you require any assistance, please don't hesitate to email our customer care team at support@whitmorejewels.com.
