How to Design a Custom T-Shirt

πŸ“… April 9, 2026 ✍️ Priya Sharma ⏱️ 7 min read

Whether you're designing your first custom tee or your fiftieth, a few core design principles make the difference between a print that looks amateur and one that looks genuinely professional.

1. Start With a Clear Purpose

Before opening a design tool, decide what the shirt is for β€” a subtle corporate uniform, a bold event tee, or a personal gift β€” since that purpose should shape every design decision that follows.

2. Color and Contrast

High contrast between design and garment color reads best both up close and from a distance. Stick to 1–3 colors for the cleanest, most cost-effective print, especially with screen printing.

3. Typography Tips

Keep text large enough to read from a few meters away, avoid overly thin fonts that can lose detail in printing, and always convert text to outlines/vector shapes before sending your final file.

4. Placement and Scale

A small chest logo (around 10cm wide) suits a professional, understated look, while a large full-front design makes a bolder statement β€” decide based on how the shirt will actually be worn and where.

5. Preparing Your Final File

Export your final design as a high-resolution PNG (300 DPI+) or, ideally, a vector file (AI, EPS, SVG) so it scales cleanly to any print size without losing quality.

πŸ’‘ Pro Tip

Print or view your design at actual size on screen before finalizing β€” details that look fine zoomed in can look very different at true garment scale.

Key Takeaways

  • Decide the shirt's purpose before starting the design.
  • High contrast and 1–3 colors print cleanest and most affordably.
  • Convert text to outlines/vector shapes before submitting your file.
  • Match placement and scale to how the shirt will actually be worn.
  • Export at 300 DPI+ or as a vector file for the sharpest print.
