X (Twitter) Image Sizes
X displays images differently depending on the aspect ratio, so size selection matters.

| 2-image post | 900x1200px | 3:4 |
Landscape 16:9 is least likely to be cropped in the timeline, making it ideal for banners and thumbnails. Portrait 4:5 takes up more screen space on mobile, making it more eye-catching.
Profile and Header
| Image Type | Recommended Size |
|---|---|
| Profile icon | 400x400px (circular crop) |
| Header image | 1500x500px |
The header image may be cropped by about 60px at the top and bottom depending on the device. Keep important elements centered.

5 Tips for Great Social Media Images
1. Upload Larger Than the Recommended Size
Social platforms re-compress uploads automatically. Preparing images about 1.5x the recommended size helps maintain quality after compression.
2. Respect the Safe Zone
Stories and Reels have UI elements overlaying the top and bottom. Keep text and key information within the center 70% of the frame.
3. Save Text-Heavy Images as PNG
Photos work fine as JPG, but images with text or logos look sharper when saved as PNG.
4. Create One Large Image and Resize for Each Platform
When repurposing one image across multiple platforms, create it at the largest needed size and resize down for each platform.
5. Check on Both Mobile and Desktop
Image display varies by device. Cover and header images especially show different areas on phone vs computer — always verify on both.

FAQ
What pixel size should I use for social media images?
It depends on the platform and post type. Landscape: 1200x675px (16:9) for X. Portrait: 1080x1350px (4:5) for Instagram. Stories/Reels: 1080x1920px (9:16). These three sizes cover most platforms.
Do I need different images for each social platform?
Ideally, yes — each platform has its own optimal size. But if that is not practical, create one image at a generous size (like 1200x1200px square) and resize for each platform.
Why does text get hidden in my Stories?
Stories and Reels overlay UI elements (username, message input, etc.) at the top and bottom. Keep important text within the center 70% of the frame, leaving the top and bottom 15% clear.
Why does image quality drop after uploading?
Social platforms automatically re-compress uploaded images. To minimize quality loss: upload images 1.5x the recommended size, save JPGs at 80%+ quality, and use PNG format for images with text.
Summary
Social media image sizes vary by platform and post type. The three essential sizes — landscape 1200x675px (16:9), portrait 1080x1350px (4:5), and stories 1080x1920px (9:16) — cover the vast majority of platforms. Upload images larger than the minimum requirement, mind the safe zone for text placement, and verify on both mobile and desktop to ensure your images look great everywhere.
