How to Measure Your Ring Size: A Complete Guide by Carats Atelier

Choosing a ring is one of the most exciting parts of creating your jewelry story—but ensuring the perfect fit is just as important. Whether you’re selecting an engagement ring, a statement piece, or a delicate everyday band, knowing your exact ring size helps your jewelry sit comfortably and beautifully on your finger.

1. Why Ring Size Matters

A well-fitted ring should slide on easily yet resist a gentle tug when removed. Too tight, and it feels restrictive; too loose, and you risk losing it. Temperature, time of day, and even hydration can slightly affect your finger size, so accuracy matters.

2. Measure at the Right Time

Your fingers tend to be slightly larger at the end of the day and smaller in the morning. For the most accurate measurement, measure your finger at room temperature, preferably later in the day when your hands are relaxed.

3. Simple Ways to Measure Your Ring Size

Option 1: Use a Ring Sizer

A ring sizer—available online or at any Carats Atelier boutique—is the most precise way to find your size. Simply slide the sizer over your finger until it fits snugly but comfortably.

Option 2: Measure an Existing Ring

If you already own a ring that fits perfectly, measure the inside diameter in millimeters and use a standard size chart to find your match.

Option 3: Use a String or Paper Strip

Wrap a thin strip of paper or string around the base of your finger. Mark the point where it overlaps, measure the length in millimeters, and compare it to a ring size chart. Be sure to avoid stretching the string too tightly.

4. Measuring Different Fingers

Each finger is unique—sometimes even on the same hand. Here’s what to keep in mind:

  • Ring Finger: The most common for engagement and wedding rings. It’s usually slimmer than your middle finger.
  • Middle Finger: Often slightly larger and a popular choice for statement rings.
  • Index Finger: Typically one of the largest; bold designs fit beautifully here.
  • Pinky Finger: Smaller and ideal for stacking or minimalist rings.
  • Thumb: Wide, confident, and expressive—thumb rings usually require a larger size.

It’s perfectly normal to have different sizes for each hand; dominant hands can be slightly larger due to muscle and bone structure.

5. Tips for the Perfect Fit

  • Measure twice for consistency.
  • Consider the ring’s width: wider bands often feel tighter.
  • If you’re between two sizes, choose the larger one.
  • When in doubt, our designers at Carats Atelier can guide you through an in-person or virtual sizing consultation.
