Common Uses for Text on Images

Text overlaid on images is everywhere online — blog post headers, social media quote cards, event flyers, product announcement banners, and call-to-action graphics. The key to text-on-image working well is ensuring the text is readable against the photo background, the typography matches the tone of the content, and the text doesn't overpower the visual.

Text-on-Image Design Tips

Create Contrast Between Text and Background

The most common mistake when adding text to images is poor contrast — dark text on a dark photo or light text on a bright sky. Add a semi-transparent dark or light overlay behind the text, or use a text outline/drop shadow to separate it from any background. Readability always trumps design aesthetics when it comes to text on images.

Limit Yourself to Two Font Styles

Using too many fonts in a single image makes it look amateurish. Stick to a maximum of two — typically one for the headline (larger, bolder, more attention-grabbing) and one for supporting text (smaller, simpler, more readable). Pairing a display/decorative font with a clean sans-serif is a timeless combination.
