• Consider mobile cropping (top/bottom 50px may be cut)
• Ensure readability across all device sizes
• Account for the new “Edit profile” button position

Content Ideas for Different Goals:

Twitter/X In-Stream Images: Maximizing Engagement

In-stream images are the heart of Twitter/X visual content, driving engagement and stopping the scroll:

Single Image Posts (1600 x 900px)

This 16:9 aspect ratio is optimal for Twitter/X’s timeline display:

Why 1600 x 900px Works Best:

• Displays perfectly without cropping
• Utilizes maximum timeline real estate
• Works across all device types
• Maintains quality when compressed
• Supports Twitter/X’s algorithm preferences
• Optimal for X Premium users sharing to their audience

Content Types That Perform Well:

• Quote graphics with branded backgrounds
• Data visualizations and infographics

• Use high contrast between text and background
• Include your brand colors subtly
• Leave 5% padding on all edges
• Consider both light and dark mode viewing
• Add your handle or logo for reshares

Alternative Single Image Size (1200 x 675px)

This smaller 16:9 format also works well:

When to Use 1200 x 675px:

• Faster loading on slower connections
• Simpler graphics that don’t need maximum resolution
• When file size is a concern
• For frequent posting (reduces bandwidth usage)

Multiple Image Posts (Collages)

Twitter/X supports up to 4 images per post:

2 Images: Each displays at approximately 506 x 506px 3 Images: One large (506 x 506px) + two smaller (253 x 506px) 4 Images: Grid layout, each approximately 253 x 506px

Multi-Image Best Practices:

• Design each image to work independently
• Maintain consistent styling across all images
• Use the layout to tell a sequential story
• Ensure text is readable in smaller display sizes
• Consider the story flow from left to right, top to bottom
• Tag products or people in individual images
