Best Practices for Twitter Images

For Post Images (16:9)

Clear focal point - Make sure your main subject is obvious
Readable text - If including text, make it large and legible
High contrast - Images should stand out against Twitter's background
Mobile-first - Most Twitter users are on mobile devices
Brand consistency - Use consistent colors and style

For Profile Headers (3:1)

Keep it simple - Avoid cluttered designs in the wide format
Center important elements - Ensures visibility on all devices
Reflect your brand - Use colors and imagery that represent you
Update regularly - Fresh headers keep your profile current
Professional quality - Your header is often the first thing people see

Common Twitter Sizing Mistakes

Using Vertical Images for Posts

Vertical images in Twitter posts create excessive whitespace and don't utilize the feed space effectively. The 16:9 horizontal format is optimal.

Ignoring Header Crop Variations

Twitter headers display differently on desktop versus mobile. Important elements placed too far from center may be cut off on smaller screens.

Wrong Aspect Ratio

Images that don't match Twitter's expected ratios get cropped automatically, often cutting off crucial parts of your image.

Text Too Small

Text in images that looks fine on desktop may be unreadable on mobile. Always test on a phone screen.
