Ring Size Guide
Finding the perfect fit for your jewelry ensures both comfort and style. One Carat's size guide offers step-by-step instructions to help you measure rings, bracelets, bangles, and necklaces with ease.
Method 1: Select a ring that fits your desired finger. Measure its inner diameter using a flexible measuring tape. Use our conversion chart to find your ring size.
Method 2: Wrap a paper strip or string around your finger, mark and measure it, then refer to our size chart.
Tips for Accurate Ring Measurement:
- Measure your finger in the evening when it's slightly larger.
- Ensure your hands are warm, as cold temperatures can shrink your fingers.
- Avoid measuring after consuming alcohol or salty foods, as they can cause swelling.
- If your knuckle is larger than the base of your finger, measure both and choose a size that slides on comfortably.

Bracelet Size Guide
A well-fitted bracelet enhances both comfort and elegance.
Step 1: Wrap a flexible tape measure around your wrist where the bracelet will sit. If using a piece of string, mark the meeting point and measure it against a ruler.
Step 2: Add 1 inch for a snug fit if your bracelet has a clasp. For bangles and cuffs, measure the widest part of your hand to ensure an easy slide-on fit.

Bangle Size Guide
Say goodbye to tight or loose bangles! Follow this step-by-step guide to find your ideal size:
Step 1: Tuck your thumb into your palm as if sliding on a bangle. Measure the widest part across your hand using a flexible measuring tape.
Step 2: Wrap a strip of paper or a flexible tape measure around your wrist and mark where the ends meet.
Alternate Method: Use an existing bangle by measuring its inner diameter with a ruler. Multiply the diameter by 3.14 (C = D × 3.14) to calculate the circumference.
