Pro Tip

Even though the upload is square, Twitter displays profile pictures as circles. Ensure your logo or face is centered and not cut off by the corners.

Header Image

The header image is the large banner at the top of your profile. It's a great space to showcase your brand's personality, current promotions, or tagline.

Safe Zones

Part of your header image may be covered by your profile picture on desktop, and cropped on mobile. Keep critical text and logos in the center of the image.

Post Image

Images attached to tweets get more engagement than text-only tweets. Optimizing them ensures they look great in the feed without awkward cropping.

Best Practices for Twitter Images

High Quality

Use sharp, clear images with good lighting and vibrant colors to grab attention in a fast-moving feed.

Minimal Text

Keep text to a minimum. If you must use text, ensure it's large and readable on mobile screens.

Brand Consistency

Maintain consistent branding (colors, fonts, style) across all your Twitter images to build recognition.

Common Mistakes to Avoid

  • Using low-resolution or blurry images that look unprofessional.
  • Adding too much text to images, making them hard to read on mobile.
  • Ignoring mobile display differences (most users are on mobile).
  • Using inconsistent branding that confuses your audience.
  • Not updating header images for special events or campaigns.

Frequently Asked Questions

What happens if I upload an image with the wrong dimensions to Twitter?

Twitter will automatically crop your image to fit the supported aspect ratios. However, this automatic cropping may not focus on the important parts of your image, which is why using a tool like SocialCrop is recommended.

Can I upload images in any file format to Twitter?

Twitter supports JPEG, PNG, and GIF formats. For the best quality and loading times, JPEG is recommended for photographs, while PNG is better for graphics with text or transparent elements.

What's the maximum file size for Twitter images?

Twitter compresses images during upload, but it's best to keep your file size under 5MB for photos and 15MB for GIFs on web. Larger files may be compressed more heavily, resulting in lower quality.
