Children's Ring Size Guide: How to Measure and Choose the Perfect Fit
Buying rings for children can be one of the trickiest jewellery purchases. Why? Because children's finger sizes can vary widely, even among kids of the same age. That’s why it's important to measure before you buy — and we’re here to help make that easy!
How to Measure Your Child’s Ring Size
The best way to ensure a good fit is by using a simple piece of string or a flexible measuring tape:
-
Wrap the string around your child’s finger where the ring will be worn.
-
Mark the spot where the string overlaps.
-
Measure the length of the string in millimetres.
-
Match this measurement to a ring sizing chart to find the corresponding US ring size — the standard size we use.
Tip: Make sure the string is snug but not tight. You want the ring to slide over the knuckle comfortably.
Children's Ring Size Chart (US Sizes)
| US Ring Size | Inside Circumference (mm) |
|---|---|
| 1 | 39.1 mm |
| 2 | 41.5 mm |
| 3 | 44.0 mm |
| 4 | 46.4 mm |
| 5 | 49.0 mm |
| 6 | 51.5 mm |
| 7 | 54.0 mm |
📏 Tip: Measure your child's finger with a piece of string, mark where it overlaps, and measure in millimetres. Then match to the chart above!
Pro Tip: Buy a Size Up for Growing Fingers
My personal suggestion is to choose one size larger than the measurement. This way, the ring will grow with your child:
-
She can start wearing it on her middle finger.
-
As she grows, she can move it to her ring finger.
-
Later on, it can be worn on her little finger.
This smart sizing trick ensures your gift lasts for many years — and with today’s trends, rings can stylishly be worn on any finger, not just the traditional ring finger!
Matching the Inside Circumference
When in doubt, always match your measurement to the inside circumference of the ring. This is the key factor in getting the sizing right.
We hope this guide helps you choose the perfect fit for your child’s special ring!
