When to Quote or Underline in Presentations

Why This Stuff Actually Matters

Most presentation advice focuses on slides, fonts, and colors. Nobody talks about text emphasis — the difference between a quote that lands and one that falls flat, between an underline that clarifies and one that confuses.

You're about to learn exactly when each technique works and when it doesn't. No theory. Just decisions you can make in the next five minutes.

When to Use Quotes in Presentations

Quotes serve one purpose: borrowed credibility. You're borrowing authority from someone else to make your point stronger.

Use Quotes When...

• The person has more authority than you on that specific topic
• You need to show disagreement with a mainstream position
• A statistic or finding needs attribution to feel credible
• The quote is short enough for people to remember
• You're telling a story and need a real person's words to anchor it

Skip Quotes When...

• The quote is longer than two sentences — nobody's listening
• You're the expert and you just want to sound smarter
• The attribution is vague ("experts say...")
• You're quoting yourself — that's not a quote, that's a key point

When to Use Underlines in Presentations

Underlines tell the audience: this specific word matters more than the others. They create hierarchy in a line of text.

Use Underlines When...

• You're defining a term for the first time
• One word in a sentence carries the weight of your argument
• You want to distinguish between similar options (verb vs. noun)
• Technical terms need visual separation

Skip Underlines When...

• You're trying to emphasize everything — that means you emphasize nothing
• Your font is already bold or italic
• You're using it on a heading or title
• Colors would work better (and they usually do)

Quotes vs. Underlines: The Direct Comparison

How to Actually Use These in Your Next Presentation

Step 1: Decide the Purpose First

Before you open your slide software, ask: am I borrowing credibility or creating emphasis?

If credibility — use a quote. If emphasis — use an underline (or better yet, color).

Step 2: Draft the Text

For quotes, keep it under 20 words. Write the attribution immediately after. Example:

"We overestimate what we can do in a year and underestimate what we can do in ten." — Bill Gates

For underlines, underline only the word that carries the meaning. Example:

You're not managing time — you're managing priorities.

Step 3: Check for Overlap

If you're tempted to both quote AND underline the same text, stop. Pick one technique. Mixing them confuses the signal.

The Common Mistakes People Make

• Quoting themselves — "As I always say..." No. Either it's important enough to stand alone or it isn't.
• Underlining entire phrases — If you need to underline more than two words, rewrite the sentence.
• Using quotes for long passages — Your audience has a five-second attention span. Cut it or lose it.
• Underlining in dark mode — Underlines disappear on dark backgrounds. Use bold or color instead.
• Quoting unknown sources — "Studies show..." means nothing. Name the study or skip it.

Quick Reference for Your Next Slide

Need to show someone else said it? Use quotes. Attribution required.

Need to stress a specific word? Use underlines sparingly. Better yet, use bold or color.

Confused about both? Rewrite the sentence until one technique is obviously right.

That's it. Three decisions. Make them consciously and your text emphasis will stop being an afterthought and start working for you.
