- Category leadership (prominence signals)
- Customer confidence (established presence)
Tip 1: Prioritize Visibility and Readability
Distance and Typography
Legibility Formula: Letter height determines maximum reading distance:
Standard Calculation: Viewing Distance = Letter Height × 100
Practical Examples:
- 100mm letters: 10m maximum distance
- 200mm letters: 20m maximum distance
- 500mm letters: 50m maximum distance
- 1000mm letters: 100m maximum distance
Typography Selection: Bold, sans-serif fonts optimize legibility:
Recommended Characteristics:
- High stroke weight (bold, medium minimum)
- Simple letterforms (minimal decoration)
- Open counters (internal spaces)
- Consistent width (regular rhythm)
- Adequate spacing (letter and word gaps)
Avoid:
- Script fonts (distance illegibility)
- Thin weights (visibility loss)
- Condensed typefaces (reading difficulty)
- Decorative fonts (comprehension delay)
- All capitals (reduced readability in long text)
Color Contrast
High-Contrast Combinations: Maximum visibility requires strong contrast:
Most Effective:
- Black on white/yellow (maximum contrast)
- Dark blue on white (professional, clear)
- White on dark blue/black (sophisticated)
- Yellow on black (high-visibility warning)
- Red on white (attention-capturing)
Avoid:
- Low contrast (pastel combinations)
- Similar tones (gray on beige)
- Color-blind problematic (red/green alone)
- Busy backgrounds (pattern interference)
Testing: Convert design to grayscale:
- Strong contrast remains visible
- Weak combinations disappear
- Verification before production
Lighting Considerations
Illumination Options: Ensure 24/7 visibility through Illuminated Signs:
Internal Illumination:
- LED channel letters (even, vibrant)
