Social Media Image Size Guide (2026)
Updated May 25, 2026
Why image size matters on social media
Every social platform displays images at specific dimensions. Upload the wrong size and the platform crops it — often badly, cutting off faces or text — or stretches it until it looks unprofessional. Sizing an image correctly before you upload puts you in control of exactly what is shown.
Below are the current recommended dimensions for the main platforms. Each links to a tool that resizes and crops any photo to that exact size, in your browser.
| Image | Dimensions | Tool |
|---|---|---|
| Square post | 1080 x 1080 | Instagram post size |
| Portrait post | 1080 x 1350 | Instagram portrait size |
| Story or Reel | 1080 x 1920 | Instagram story size |
Portrait posts take up more feed space than square ones, which is why many creators prefer them.
YouTube
| Image | Dimensions | Tool |
|---|---|---|
| Video thumbnail | 1280 x 720 | YouTube thumbnail size |
| Channel banner | 2560 x 1440 | YouTube banner size |
The channel banner is shown at different crops on phone, desktop, and TV, so keep important elements near the center.
X (Twitter)
| Image | Dimensions | Tool |
|---|---|---|
| Header banner | 1500 x 500 | X header size |
| In-feed post image | 1200 x 675 | X post image size |
Facebook, LinkedIn, TikTok, and Pinterest
| Image | Dimensions | Tool |
|---|---|---|
| Facebook cover photo | 820 x 312 | Facebook cover size |
| LinkedIn profile banner | 1584 x 396 | LinkedIn banner size |
| TikTok video | 1080 x 1920 | TikTok video size |
| Pinterest pin | 1000 x 1500 | Pinterest pin size |
Two tips for sharp social images
- Start from a large source. Each tool scales your image to cover the target frame and crops the overflow, so proportions stay correct. Starting from a photo larger than the target keeps the result sharp — enlarging a small image looks soft.
- Mind the file size. Platforms re-compress what you upload, but a smaller starting file uploads faster. If needed, run the result through the image compressor.
Dimensions do shift as platforms redesign, but the sizes above reflect current guidance. When in doubt, a larger image at the right aspect ratio is always safer than a small one.
