X post image size: plan for the crop, not just the upload.
Prepare product screenshots and announcement graphics for a fast mobile timeline. A wide 16:9 asset or square image can both work, but media count and platform surfaces can affect presentation.

QUICK ANSWER
Start with the job, then choose the frame.
A 1600 × 900, 16:9 canvas is a useful workflow for wide X media, while square artwork can suit compact posts. Treat both as design starting points and preview the actual post because X may present media differently by device, surface, and attachment count.

Choose wide when the product is naturally wide
Dashboards, browser views, and video stills often fit 16:9. Do not force a narrow mobile screen to fill the width; use composition and background space to preserve its shape.
Use square for compact visual statements
Square can give a diagram, quote, or centered product card a stable footprint. Keep text large and avoid assuming that square is the only crop viewers will encounter.
Attachment count changes the media layout
Multiple images can be arranged differently from a single image. Preview the exact number and order of attachments in the current composer instead of validating each file in isolation.
Prepare crop-resilient media for X
Validate the complete post, not only the exported rectangle.
- Choose a wide or square working canvas based on the actual product evidence.
- Place essential copy and the decisive screen region near the compositional center.
- Test the exact attachment count and ordering in the current X composer.
- Review the mobile timeline preview, then adjust scale or crop before publishing.
Twitter post image size FAQ
What size should an X or Twitter post image be?
A 1600 × 900 wide canvas or a square image is a practical starting point. Preview the current X post because presentation can vary.
Does X crop images in the feed?
Media presentation can depend on aspect ratio, surface, device, and number of attachments. Keep essential content centered and inspect the composer preview.
Can I post more than one product image?
Yes, but the multi-image layout changes available crops. Test the exact set together and order the strongest visual first.
