Choose a font that stays clear at a distance

Look for open, distinct letter shapes

The reader should quickly distinguish I, l, 1, O, 0, C, and G. Open counters and simple terminals help letters remain recognizable when the screen is small in the field of view.

A familiar sans serif is a dependable starting point because the shapes do not ask the reader to decode a visual style before understanding the message.

Use weight and width carefully

Bold strokes survive distance and glare, but extremely heavy letters can close the spaces inside characters. Very condensed fonts fit more text while making similar letters harder to tell apart.

Do not solve a long sentence only by compressing it. Shorten the wording first, then use the largest comfortable width and weight.

• Prefer bold over thin
• Prefer normal width over extreme condensation
• Keep visible space between letters
• Avoid novelty fonts for essential information

Test the exact names and numbers

A font that looks good in a sample may fail on the passenger name, gate number, price, or abbreviation you actually need. Test the real message, including accents and non-Latin characters.

Walk to the intended distance and ask someone unfamiliar with the content to read it. If they hesitate, simplify before adding effects.
