Challenge Coin Sizes Overview
There is no absolute standard for challenge coin size, but they usually fall between 1.5 and 3 inches in diameter. Choosing the right size depends on striking the right balance between design detail, purpose, budget, and overall visual appeal.
Smaller coins are ideal for portability and simplicity, while larger coins allow for detailed artwork and a more commanding presence. While 1.75, 2 inches is the most popular choice, smaller or larger coins each serve different design goals.

  • 1.5 inches
    1.5" Challenge Coins — About 38.1 mm

    1.5-inch coins are the smallest standard size and are perfect for situations where portability matters. Units and organizations often use them for quick recognition, training completions, volunteer appreciation, or pocket tokens meant to be carried daily.
    They fit easily in a wallet or uniform pocket, making them great for morale boosts and handshake gifts. Even with their compact size, they still allow for simple logos, short mottos, and clean line work. If you're looking for a practical coin that people can keep with them at all times, 1.5" is an excellent choice.
  • 1.75 inches
    1.75" Challenge Coins — About 44.5 mm

    1.75-inch coins hit the sweet spot between size and detail. It’s one of the most popular dimensions across the military, police departments, fire services, clubs, and event organizers.
    This size offers enough space for most artwork—crests, seals, symbols, and detailed text—while still being comfortable to carry. Whether you're making team coins, graduation coins, command tokens, or community-focused designs, 1.75" delivers a balanced feel that works for almost every purpose.
  • 2 inches
    2" Challenge Coins — About 50.8 mm

    A 2-inch challenge coin has a strong presence and is widely viewed as a “premium standard” size. It’s large enough to capture intricate design elements like landscapes, building silhouettes, 3D emblems, or layered color fills, yet small enough to hand out at ceremonies or tuck into a presentation box.
    Many choose this size for command coins, retirement gifts, police unit coins, and commemorative pieces marking major achievements or historic events. If you want your artwork to truly stand out, 2" gives you room to make it memorable.
  • 2.25 inches
    2.25" Challenge Coins — About 57.2 mm

    2.25-inch coins feel solid in the hand, making them ideal for moments that deserve extra recognition. This size is often selected for promotions, long-service awards, unit anniversaries, special edition coins, or challenge coins that need layered 3D sculpting.
    The additional space lets you incorporate more storytelling—timelines, mottos, badges, or dual-theme artwork on each side. Many collectors appreciate 2.25" pieces because they display well on shelves, stands, and shadow boxes.
  • 2.5 inches
    2.5" Challenge Coins — About 63.5 mm

    At 2.5 inches, challenge coins step into a more collectible and display-focused category. This size is perfect when your design includes complex scenes, multiple symbols, or detailed backgrounds that would feel crowded on a smaller coin.
    They are often used for limited editions, special leadership presentations, historic commemorations, and premium sets. The larger diameter gives your coin a real sense of weight and presence—something people immediately notice when they pick it up.
  • 2.75 inches
    2.75" Challenge Coins — About 70 mm

    2.75-inch coins make a bold and impressive statement. This size allows for detailed 3D sculpting, multi-level plating, full panoramic artwork, or illustration-style designs that span across the entire coin.
    They’re popular for gala events, major organizational milestones, museum collections, and top-tier recognition pieces. These coins are usually intended for display rather than everyday carry, and they stand out immediately in any challenge coin collection.
  • 3 inches
    3" Challenge Coins — About 76.2 mm

    A 3-inch challenge coin is truly oversized and commands attention. These coins are often the centerpiece of a collection—chosen for high-rank presentations, commemorating historic achievements, foundation anniversaries, or large-scale challenge coin series.
    The larger surface gives you room to tell a fuller story with richer detail. A 3-inch coin feels more like a medallion and is usually displayed in cases or plaques. If you want a piece that truly stands out and leaves a lasting impression, this size delivers maximum impact.

Challenge Coin Sizes Overview

5
Choosing the perfect challenge coin size depends on design complexity, purpose, budget, material thickness, and shape. Follow these tips to choose the perfect coin size:

DESIGN DETAIL

More intricate designs require more space to showcase details clearly.
Recommendation: For complex artwork, consider 2” or larger coins.

BUDGET

Larger coins use more metal, which increases costs.
Recommendation: For a cost-effective option, smaller coins like 1.5”-1.75” are ideal.

PURPOSE

Pocket-friendly or casual carry: 1.5”-1.75” coins are easy to carry and store.
Display, awards, or presentation pieces: 2”-2.5” coins create a stronger visual impact.

MATERIAL & THICKNESS

Larger coins can support thicker specifications (3mm+), giving a heavier, more substantial feel.
Heavier coins often convey prestige and significance.

SHAPE

Custom silhouettes may slightly reduce the usable artwork area.
Tip: When choosing unique shapes, consider slightly larger diameters to ensure all design elements are clearly visible.

Design, Weight & Cost

Here's a quick reference:

Regarding making challenge coins, size, weight, and cost are all interconnected. As the diameter increases, so does the amount of metal, plating, and detail — all of which impact both price and presence.

Larger coins allow more intricate designs but also come with higher production costs. For most projects, the 2-inch standard coin offers the perfect balance between visual impact, weight, and budget efficiency.

Challenge Coin Thickness

7
When designing your custom challenge coins, thickness plays a crucial role in both appearance and feel. While the standard challenge coin thickness is around 3mm, many collectors and organizations prefer thick coins (up to 3.5mm or 4mm) for a more premium, weighty presence.

Choosing the right thickness of a coin depends on your design details and purpose — thicker coins allow for deeper 3D relief, intricate engravings, and a more substantial hand feel.

How Challenge Coin Sizes Are Measured

8
How Challenge Coin Sizes Are Measured
How Challenge Coin Sizes Are Measured
We measure each challenge coin by its longest side. For round coins, this refers to the diameter; for custom-shaped or irregular designs, it means the widest point across the entire piece.
When two designs share the same width but differ in height, they will be priced the same as long as the height does not exceed the width. All pricing is determined by the coin’s longest side to ensure fair and consistent quotations.

Frequently Asked Questions

9

[Standard Coin Size]
What is the standard size for challenge coins?

The standard size for most challenge coins ranges from 1.75" to 2" in diameter. This size feels substantial in the hand but still fits easily in a pocket or wallet. It’s also large enough to include detailed artwork, 3D reliefs, and clear text around the border. Many military and corporate coins use this range because it balances practicality and visual impact perfectly.

[Coin Size]
What size coins do the military or police use?

Military and police challenge coins are often slightly larger — typically 2" to 2.25" in diameter. These coins usually feature detailed insignias, badges, and unit mottos that require extra space to show clearly.
Command coins, in particular, may reach 2.5" or even 3", especially when given as presentation pieces or awards of honor. The extra size gives them a stronger presence and makes them ideal for display cases or ceremonies.

[Maximum Coin Size]
How big can custom coins be made?

Our production capabilities allow any size of coins. Oversized coins are a favorite among collectors and organizations that want their designs to stand out. Larger sizes work beautifully for wall plaques, recognition awards, or limited-edition collector runs.

[Coin Size & Cost]
Does coin size affect cost?

Yes, coin size has a direct effect on production cost. Larger coins require more metal. That said, we always offer transparent, itemized quotes before production, so you can adjust dimensions to stay within budget.

[Standard Coin Thickness]
What is the standard coin thickness?

The standard thickness for most challenge coins is about 3 mm (roughly 0.118 inch). This size gives the coin a solid, well-balanced weight while still being comfortable to carry. If you prefer a solid, heavy feel, 3.5 mm and 4 mm thicknesses are available.
Thicker coins allow for deeper relief and more detailed 3D or sculpted designs. That said, our standard 3 mm coins already handle these techniques beautifully — thicker versions simply give designers a bit more creative space to work with.

[Coin Size Measuring]
How is coin size measured for irregular or custom shapes?

For coins that aren’t perfectly round — such as dog-tag shapes, shields, or emblems — the measurement is taken from the longest distance between two opposite edges.
This ensures the pricing and mold size accurately reflect the true maximum dimension of your coin. In other words, even if your design includes cut-outs or non-circular forms, the “size” we quote will always represent its widest point for consistency.

[Choose]
How can I decide which size fits my design best?

Don’t worry! Just tell us how the coin will be used or what kind of look and feel you want, and we’ll recommend the ideal size, thickness, and finish for your project. Whether it’s a small keepsake for daily carry or a larger piece for display, we’ll make sure it fits your vision perfectly.
