Other Things to Consider Before Choosing a Material

  • Brand Identity: What message are you sending to your customers? Consider how the material aligns with your brand's tone—whether that's fun and innovative or timeless and trustworthy.
  • Budget: Some materials offer high-end finishes at a premium. If needed, flexing on certain design features can help meet your budget.
  • Durability: Consider traffic and placement. Materials closer to touchpoints may need to withstand more wear.
  • Customizability: Think through what each material offers. Do you want a high-gloss look? Bright colors? Subtle elegance? Customization is key to making the right impact.
