Typography Tips for Image Text
Contrast is essential: Text must be readable against the image background. White text on dark areas; dark text on light areas. A semi-transparent background behind text solves contrast problems.
Font choice: Sans-serif fonts (Arial, Helvetica, Inter) are more readable than serif fonts at small sizes on screen. Bold weight improves readability.
Size: Text should be readable at thumbnail size. If text looks fine at 100% but is unreadable at 25%, it is too small.
Line length: Keep each line under 10-12 words for best readability.
Text Placement
Avoid placing text over the main subject. Use negative space (sky, plain backgrounds, edges). Lower third (bottom of image) is a natural place for captions. Centre placement works for quotes but can obscure subjects.
Exporting with Text
Save as JPG if text will not change. The text becomes part of the image — it cannot be edited later.
Save as PNG if transparency is needed under the text.
Keep the source file (PSD, Figma, etc.) if you may need to edit later.
Frequently asked questions
What font is best for text on images?
Bold sans-serif fonts (Montserrat, Inter, Arial Bold) are the most readable on images. Avoid thin or decorative fonts for small text.
How do I make text readable on any background?
Add a semi-transparent dark or light background behind the text, or add a text shadow/outline. White text with a dark shadow works on almost any background.
