Free Contrast Checker for Social Media Graphics
Verify color contrast in social media posts, stories, and ads. Ensure text is readable on Instagram, Facebook, and LinkedIn. Free tool.
Social media graphics are viewed on small screens, often while scrolling quickly. If your text overlay doesn't have enough contrast against the background image or color, your message gets lost. High contrast stops the scroll and ensures your content is accessible to all users.
Tips for Social Media
Always add a semi-transparent overlay behind text placed on photos — even beautiful images can make text unreadable
Test your graphics at mobile size (375px wide) — what looks fine on your desktop may be illegible on a phone
Check contrast for text on gradient backgrounds at both the lightest and darkest points
Use bold, high-contrast text for the main message — save subtle colors for secondary elements only
Try This Example
“Check if my Instagram post text #FFFFFF on a dark overlay #00000080 has enough contrast for readability”
