How to Choose the Right Challenge Coin Size
Most customers order 1.75" or 2" challenge coins. These sizes balance portability with enough space for logos, text, and custom edges. If your design includes detailed imagery or you want the coin to feel like a premium keepsake, go with 2" or 2.25". For large events where you need to control cost, 1.5" keeps the price down while still delivering a quality product.
Size by Use Case
- Military challenge coins: 1.75" to 2" are the most popular. Unit coins often use 1.75" while commander's coins and commemorative issues use 2".
- Corporate challenge coins: 1.75" to 2" work well for employee recognition, brand launches, and trade show giveaways.
- Commemorative coins: 2" to 2.5" give the coin presence and make it suitable for display cases.
- Police and fire department coins: 1.75" to 2" are standard, often with antique finishes and custom edges.
Challenge Coin Thickness and Weight
Thickness ranges from 2.5 mm to 4 mm. A 3 mm thickness is standard for most coins under 2". For 2" and larger, 3.5 mm to 4 mm gives the coin a solid feel. Zinc alloy is the most common material and provides a good weight-to-cost ratio. Brass and copper are heavier and feel more premium.
