How to Highlight Text in PowerPoint: Precision Styling for Presentations

Text highlighting in slides makes key points pop instantly. I learned this the hard way during a Carnegie Mellon presentation where my professor called out my wall-of-text slides.

The built-in highlighter tool hides in plain sight on the Home tab. No special downloads, no complex steps—just select text and pick a color. The trick is using contrast that works on projectors, not just your monitor.

You’ll transform boring bullet points into scannable, professional content that guides your audience’s attention. Works across all modern PowerPoint versions, including the web edition.

Between you and me, this one formatting skill makes you look like a presentation pro with zero design experience required.

What Youll Need

Instructions

These are the exact steps I use to apply clean, professional text highlighting in any presentation.

Open your PowerPoint presentation and navigate to the slide containing the text. Click and drag to select the specific portion you want to highlight. If you need to highlight an entire text box, click the box’s edge to select all text within it.

Verify your selection by checking that the chosen text is surrounded by a dotted outline. This confirms you’ve got the right content selected before applying any formatting. Precise selection prevents accidentally highlighting unintended text.

With your text selected, look to the Home tab on the ribbon. In the Font group, locate the Text Highlight Color button—it looks like a marker with a colored underline. Click the dropdown arrow next to it to reveal the color palette.

Choose your preferred highlight color from the available options. As you hover over each color, PowerPoint will preview the effect on your selected text. Click your chosen color to apply it. The highlight will appear behind the text, not as a font color change.

If the default colors don’t match your presentation’s theme, select More Colors… from the highlight color dropdown. This opens the Colors dialog where you can define a custom RGB or HEX value to match your brand or slide design exactly.

For consistent highlighting across multiple slides, note the exact color values you use. This ensures uniformity throughout your presentation. I always keep a small text box with sample colors on a hidden slide for reference during editing.

To change an existing highlight, simply select the highlighted text and choose a new color from the Text Highlight Color menu. The new color will replace the old one immediately, with the preview showing before you click.

To remove highlighting entirely, select the text and click the Text Highlight Color button, then choose No Color from the palette. The highlight will disappear while leaving the text itself unchanged. This is particularly useful when repurposing slides for different presentations.

For more creative highlighting, use the Drawing Tools. On the Home tab, click the Shapes dropdown and select the Line tool. Then choose the Highlighter option from the Shape Styles section.

This activates a freehand highlighter that works like a physical marker. Click and drag across any portion of your slide to create custom highlight shapes. Adjust the color and thickness using the Shape Format tab that appears when the highlighter is selected. This method works for highlighting across multiple objects or irregular areas.

Tips and Common Mistakes

Small details make the difference between amateur and polished presentations.

Precision Selection: In Step 1, take an extra second to verify your text selection shows that dotted outline. I can’t count how many times I’ve accidentally highlighted a period or space because I rushed this part. The preview in Step 2 will show exactly what you’ve selected before committing to a color.

Color Consistency Hack: For Step 3, create a color reference slide as I do. Jot down the exact RGB or HEX values you use for each highlight color in a text box on a hidden slide. This becomes your style guide for the entire presentation, ensuring every highlighted element matches perfectly.

Undo Safety Net: Before applying any highlight in Step 2, make sure you’ve saved your presentation. While PowerPoint’s undo function is reliable, I’ve learned the hard way that a saved version is your best insurance against accidental formatting changes.

Freeform Highlighting Pro Tip: When using the highlighter tool in Step 5, start with a thicker line weight than you think you need. You can always adjust it thinner in the Shape Format tab, but it’s easier to reduce than to thicken an almost-invisible line.
