Which envelope formatting option is most readable?

• A. Lower case with punctuation
• B. Light type on light background
• C. Script or italic font
• D. Capital letters in block format

Answer: (D)

Readable envelope text relies on clarity, contrast, and consistent letterforms. Capital letters in block format achieves that by using uniform letter shapes and a clean, left-aligned layout, making the address easy to recognize quickly for both people and scanning systems. The consistent height and spacing reduce ambiguity between similar-looking characters and help the eye move along the lines without distraction. The other options undermine readability: lowercase with punctuation introduces varied shapes and potential misreads; light type on a light background lowers contrast, making letters harder to discern; script or italic fonts have flowing, connected shapes that are more difficult to read at a glance and are less reliable for quick recognition.
