Ring Size Guide: How to Find Your Perfect Fit with Uniglo Jewels

When it comes to choosing the perfect ring, finding the right size is essential. A well-fitted ring is comfortable, secure, and enhances the beauty of your jewelry. But how do you determine the right size when shopping online? In this guide, we’ll walk you through simple steps to measure your ring size and ensure a flawless fit.

1. Measure Your Finger at Home

You can easily measure your ring size at home with just a few tools. Here are three methods to try:

Option 1: Use a Ring Sizer

If you have access to a ring sizer, it’s the most accurate way to find your size. Many jewelers, including UnigloJewels, offer free ring sizer tools you can order or download.

Option 2: Use String or Paper

  • Step 1: Take a piece of string or a strip of paper and wrap it around the base of your finger (where the ring will sit).
  • Step 2: Mark where the ends meet, then measure the length in millimeters.
  • Step 3: Compare the measurement to a ring size chart to find your corresponding size.
Ring Size (US)Inside Circumference (mm)
549.3
651.9
754.4
857.0

Tip: Measure your finger when it’s warm, as fingers can shrink slightly in cold weather.

Option 3: Measure an Existing Ring

If you already own a ring that fits perfectly, you can measure its diameter to find your size:

  • Step 1: Use a ruler or caliper to measure the internal diameter of the ring (from one inside edge to the other, in millimeters).
  • Step 2: Match this diameter to the ring size chart for an accurate fit.
Ring Size (US)Inside Diameter (mm)
515.7
616.5
717.3
818.2

2. Keep Comfort in Mind

The perfect ring size should slide over your knuckle with slight resistance and feel snug on your finger without being too tight. Keep in mind that:

  • Fingers can swell during the day, so it’s best to measure when your hands are at room temperature.
  • Ring width matters: Wider bands will fit more snugly than thin bands, so you may want to go up half a size for thicker rings.

3. International Ring Size Conversion

If you’re shopping from outside the US or are gifting someone in a different country, you’ll want to use an international ring size conversion chart. Here’s a quick reference:

4. Tips for Surprise Ring Sizing

Planning a surprise proposal or gift? Here are some tricks to figure out your partner’s ring size discreetly:

  • Borrow a ring they already wear on their ring finger (but make sure it’s from the correct hand and finger!).
  • Ask their friends or family for advice—they might already know the size.
  • Use a casual conversation to subtly ask about jewelry preferences and ring size without giving anything away.

5. Resizing Your Ring

If you purchase a ring and discover it’s not the perfect fit, don’t worry. At UnigloJewels, we offer resizing services for many of our rings. Simply contact us, and we’ll help adjust the ring for a comfortable fit.
