The Big and Small of It All: Determining Lettering Font Sizes for Signs

Your business sign is often the first impression you make on potential customers. It needs to be eye-catching, informative, and legible from a distance. But how do you determine the right font size for your lettering? Let's dive into the world of sign typography and explore the factors that influence the ideal letter size.

Key Considerations:

  1. Viewing Distance: This is the most crucial factor. Imagine someone walking towards your sign. At what distance do you want them to be able to read the message clearly? The further the viewing distance, the larger the font needs to be.
    • General rule: For every 10 feet of viewing distance, increase the letter height by 1 inch. So, for a sign 50 feet away, you would want letters at least 5 inches tall.
  2. Sign Size and Shape: The size of your sign will naturally influence the letter size. A larger sign can accommodate larger lettering, while a smaller sign may require smaller, condensed fonts. Additionally, consider the shape of your sign. Narrow signs may require taller letters to maintain legibility.
  3. Legibility of the Font: Choose a font that is easy to read from a distance. Avoid overly ornate or delicate fonts, as they can be difficult to decipher. Sans-serif fonts are generally considered more legible than serif fonts.
  4. Number of Lines of Text: Keep the number of lines of text to a minimum. A cluttered sign with too many lines can be overwhelming and difficult to read.
  5. Local Regulations: Some areas have regulations that specify the minimum size for lettering on signs. Check with your local building department to ensure your sign complies with local codes.

Additional Tips:

  • Use uppercase and lowercase letters: This improves readability compared to all uppercase text.
  • Consider letter spacing and line spacing: Adequate spacing between letters and lines ensures clarity and prevents the text from appearing cramped.
