Class Ring Size Guide: How to Measure & Size a Class Ring

If this is your first time sizing a ring at all, you're not alone — class rings are often exactly that for students and parents alike. Here's a straightforward guide made for exactly that situation.

Quick answer: Measure your finger the same way you would for any ring, but expect to size up slightly — class rings are traditionally bulkier and heavier than an everyday band, and most companies mail a free plastic sizing kit before you finalize your order, which is worth using.

Why class ring sizing is its own situation

Class rings are frequently the first ring someone ever gets properly sized for — which means the usual assumptions about ring sizing (that you already know your size, that you're used to how rings fit) often don't apply.

A Typical Ring Buyer

  • Has likely worn rings before and has a rough sense of their size
  • Usually buying a thinner, everyday-style band

A Class Ring Buyer

  • Often sizing a ring for the very first time, with no prior reference point
  • Buying a traditionally bulkier, heavier design than an everyday band
  • Sometimes still a teenager whose hand may not be fully done growing

The underlying measuring method is the same one used for any ring — see our full how to measure ring size guide if you want the complete step-by-step walkthrough. This page covers what's specific to the class ring situation.

A Common Question

Which hand does a class ring go on?

In the US, class rings are traditionally worn on the ring finger of the right hand — the opposite of where an engagement or wedding ring typically goes. This isn't a strict rule, though; plenty of people wear theirs on whichever hand feels comfortable, or switch it after graduation. If you're unsure, right hand, ring finger is the safe traditional default.

Step by Step

How to measure your class ring size

  1. Measure the correct finger and hand — typically the right ring finger, per tradition, unless you already know you'll wear it elsewhere.
  2. Use the sizing kit if your school's ring company sent one. Many class ring companies (Jostens, Balfour, and similar) mail a free plastic ring sizer as part of the ordering process — it's designed specifically for their rings and is worth using over a generic paper strip if you have one.
  3. If you don't have a kit, the standard paper strip or string method works just as well — full instructions are in our measuring guide, and you can cross-check your result against our full ring size chart.
  4. Account for the bulkier design. Class rings are traditionally thick and substantial, similar to a wide band — size up slightly from a thin-reference measurement. See our band width guide for the general adjustment pattern.
Worth Knowing

If you're still growing: measure now, not months ahead

Class rings are often ordered months before delivery, which can tempt an early measurement. If you're a younger student, hand size can still shift somewhat during the ordering window — measure as close to the actual order deadline as your school allows, rather than as early as possible.

Don't guess based on a parent's size or an old measurement. Even a sibling's class ring size from a year or two earlier isn't a reliable stand-in — measure your own hand directly, at the time you're actually ordering.
Long-Term Thinking

Class rings are often resized years later

Unlike many rings, class rings are frequently kept for decades — some people resize theirs as an adult to wear again, pass down to family, or repurpose for a graduation gift. If your hand size has changed significantly since your school years, this is completely normal and usually straightforward to fix.

Frequently Asked

Class ring size: frequently asked questions

What size class ring should I order?

Measure your finger directly — using the sizing kit your class ring company sent, or a paper strip or string — and size up slightly since class rings are traditionally bulkier than an everyday band.

How do you measure class ring size?

The same core method as any ring: wrap a strip snugly around the base of the correct finger, mark the overlap, and measure in millimeters. Many class ring companies also mail a dedicated plastic sizing kit.

What hand does a class ring go on?

Traditionally the right hand, ring finger, in the US — though this isn't a strict rule and many people wear theirs differently.

Should I size up for a class ring?

Generally yes, since class rings tend to have a thicker, bulkier shank than an everyday band, similar to sizing considerations for any wide ring.

What if I'm still growing when I order my class ring?

Measure as close to the actual order deadline as possible, rather than far in advance, since hand size can still shift somewhat for younger students.

Can a class ring be resized years later?

Usually, yes — this is common, since many people keep class rings for decades and resize them as adults. See our resizing cost guide for typical pricing.
