Free Contrast Checker for Presentations

Check slide color contrast for PowerPoint, Keynote, and Google Slides presentations. Ensure readability from the back of the room. Free tool.

Presentations are viewed on projectors, large screens, and laptops — often from a distance and in rooms with ambient light. Poor contrast in slides means your audience can't read your content, which undermines your entire message.

Tips for Presentations

1

Use a higher contrast threshold for presentations (5:1+) since projectors wash out colors significantly

2

Avoid red text on dark backgrounds and blue text on black — these combinations fail on most projectors

3

Test your slides with the projector or screen you'll actually use — colors shift dramatically between displays

4

Keep text large (24pt+) and high-contrast — your slides should be readable from the back row

Try This Example

“Check if white #FFFFFF text on my slide background #2C3E50 provides enough contrast for a conference presentation”
