Choosing the right size and thickness is an important part of ordering wholesale custom keychains. Size affects how clearly your artwork and text can be displayed, while thickness determines how solid the finished product feels.
For simple metal designs, we generally recommend starting at 1.25 inches with a thickness of at least 1.5 mm. This provides enough room for a clean layout and gives the finished piece a more substantial feel.
This guide covers the most common options and explains how to choose the right specifications for your design.
Common Keychain Sizes and Thicknesses
Acrylic
Common options for promotional items, artist merchandise, and collectibles.
Good for simple logos, short text, and high-volume giveaways. It is lightweight, easy to carry, and budget-friendly.
A practical choice for artwork, character graphics, and branded merchandise. It provides clear detail without feeling bulky.
Suitable for detailed artwork, collectible merchandise, and luggage tags. The extra material adds strength and a more substantial feel.
Metal and Enamel
Compact options with enough weight for a solid, finished feel.
Works well for most logos, text, and simple artwork. The natural weight of metal keeps the finished piece compact while still feeling solid.
Better for sculpted artwork, deep molding, and premium retail pieces. The added depth supports larger and more complex details.
PVC and Rubber
Flexible construction that supports raised and layered details.
Offers a good balance of flexibility and support. It holds raised details clearly while remaining soft enough for everyday use.
Size and Thickness for Complex Designs
Acrylic
Best for multi-character illustrations, backgrounds, gradients, small printed text, and decorative details.
The larger print area helps keep faces, lettering, and background elements from running together. Use 4 mm for layered pieces, epoxy coatings, or shapes with narrow wings, tails, or other extended areas.
Metal and Enamel
Suitable for badges, animal faces, vehicles, buildings, and artwork with several color sections or raised metal details.
A practical range for designs that combine a name, date, border text, and several enamel sections. The added space makes the layout easier to read and keeps the metal lines properly separated.
Better for sculpted animals, architecture, vehicles, and mechanical details. The extra depth gives the raised and recessed areas enough room to stand apart.
PVC and Rubber
A good option for mascots and cartoon characters with separate facial features, clothing, accessories, or multiple raised levels.
This combination provides enough depth to separate the face, clothing, accessories, and other raised sections. Designs with deeper textures or additional levels may require more than 5 mm.
VeperPins’ Quick Recommendation Chart
While we’ve listed several size and thickness options above, you don’t need to finalize every detail before ordering. Use these recommendations as a starting point, and once we review your artwork, we’ll adjust the specifications to suit your design.
| Your Priority | Best Choice | Start Here | When to Adjust |
|---|---|---|---|
| Sharp artwork and full color | Acrylic | 2.5 inches (63 mm) 3 mm thick | Move up to 4 mm for layered pieces or shapes with long, narrow areas. |
| Raised texture and character designs | PVC | 2 inches (51 mm) 4 mm thick | Move up to 5 mm when the artwork has deeper layers or heavier texture. |
| A solid, premium finish | Metal and Enamel | 1.5 inches (38 mm) 2 mm thick | Increase the size or thickness for 3D relief and larger sculpted details. |
| Large promotional orders | Single-Sided Acrylic | 2 inches (51 mm) 3 mm thick | Choose a larger size when the design includes small text or more detail. |
These are starting points, not fixed rules. The final size may change slightly depending on the artwork, shape, quantity, and intended use.
