How to Choose the Right Size for your Challenge Coin

“What is the standard size for a challenge coin?”

“This is my design, what size should I customize it to?”

We often get asked these kinds of questions about size. As manufacturers of challenge coins, we provide size suggestions to thousands of customers. In this article, we will reveal how to choose the right size for your challenge coin based on our practical experience.

Let’s get started.

I. What Are The Most Popular Sizes Of Challenge Coins?

Comparison of Standard Sizes of Challenge Coins

First, let’s answer the first question: what is the standard size for a challenge coin?

The answer: there is NO standard size for a challenge coin.

Some people say: 1.75″, some say it’s 2″. But actually, these are not correct. Challenge coins are customizable products. Their shape, content, and function vary, all of which can influence the size of the challenge coin. So, we can’t determine a standard size.

Let’s discuss the common sizes for challenge coins. The most common sizes are:

1.75 inches, 2 inches, 2.5 inches, 3 inches, 3.5 inches.

These common sizes apply to military challenge coins, police challenge coins, corporate coins, and firefighter challenge coins.


II. Coin Sizes In MM VS Challenge Coin Sizes In Inches

Customers from the United States usually express sizes in inches, while customers from Southeast Asia, Middle East countries, and Germany usually use millimeters. To provide a unified understanding of size, we list a comparison table of common challenge coin sizes in inches and millimeters:











III. Is There Any Standard Challenge coin Thickness?

Challenge coins do have a standard thickness. The standard thickness is 3MM and 3.5MM. Some customers prefer a thickness of 4MM. But remember, the thickness can be customized. So, you don’t have to follow the standard thickness when customizing your challenge coin. Your preference is also an important reference.

For a regular 2D challenge coin, a thickness of 3MM is enough.

If your design is a 3D challenge coin, then the thickness should be 3.5MM or even 4.0MM for the 3D effect to be better displayed.

IV.  How to Choose a Size for My Coin Design?

How to Choose between Various Sizes of Challenge Coins

So, how should you choose the right size for your challenge coin? When we decide on the size of a challenge coin, we usually consider its design, text size, content, and function.

1. Challenge coin design

When we talk about the design of a challenge coin, we mean the content, logo, and text the coin expresses. A challenge coin should fully display these details, so its design is one of the most important criteria. When choosing the size of your challenge coin, remember to consider this factor. If you need help, feel free to fill out the form below and send us your design. We will provide professional advice. This service is free.

2. Function

Challenge coins can come with a keychain accessory, serving as a pendant. In this case, we need to consider the weight of the challenge coin; it should not be too heavy. So, when you design it, 1.75″, 2″ is enough.

Challenge coins can also function as bottle openers. Here, we need to consider the ease of use of the bottle opener function. The recommended sizes are 2″, 2.25″, 2.5″, and 3″.

3. Budget

If your budget is limited, you can opt for smaller sizes like 1.5″ and 1.75″. Try to keep the color design simple, retaining 1-3 colors. This can significantly reduce your costs.

4. Usage

If your challenge coin is for rewarding employees, we suggest a size of 4″-5″. Engrave their names and tenure on it. Such gifts are very popular.

If your challenge coin is to serve as a souvenir, 1.75″ or 2″ is enough.


1.5″-2.5″   2.5″-3.5″
  • Round Coin
  • Awards & Prizes
  • Carrying Coins
  • Dog tag
  • Gadget Coins like bottle openers, spinners, etc
  • Badges
