Social media platforms crop, resize, and compress every image you upload. Using the wrong dimensions means your images look pixelated, important elements get cropped, or the platform's re-compression artifacts are visible. This guide lists the optimal image sizes for every major platform in 2026.
Instagram image sizes
| Format | Dimensions | Aspect ratio |
| Square post | 1080 × 1080 px | 1:1 |
| Portrait post | 1080 × 1350 px | 4:5 |
| Landscape post | 1080 × 566 px | 1.91:1 |
| Story / Reel cover | 1080 × 1920 px | 9:16 |
| Profile picture | 320 × 320 px (displayed at 110 px) | 1:1 |
Instagram compresses JPEGs aggressively. To minimise re-compression artifacts, upload at exactly 1080 px width as a high-quality JPEG (85–90). Videos and Reels perform better at exactly 1080×1920.
Facebook image sizes
| Format | Dimensions |
| Feed post (recommended) | 1200 × 630 px |
| Feed post (square) | 1080 × 1080 px |
| Cover photo (page) | 820 × 312 px |
| Cover photo (profile) | 820 × 312 px |
| Profile picture | 170 × 170 px |
| Story | 1080 × 1920 px |
| Event cover | 1920 × 1005 px |
Twitter / X image sizes
| Format | Dimensions |
| In-tweet image (landscape) | 1600 × 900 px (16:9 displayed) |
| In-tweet image (portrait) | 1080 × 1350 px |
| Profile picture | 400 × 400 px |
| Header / banner | 1500 × 500 px |
X (formerly Twitter) displays a cropped 16:9 preview in the feed. Ensure the key part of your image is centred, as the crop focuses on the middle of the image.
LinkedIn image sizes
| Format | Dimensions |
| Feed post image | 1200 × 627 px |
| Profile picture | 400 × 400 px |
| Background / banner | 1584 × 396 px |
| Company logo | 300 × 300 px |
| Company cover | 1128 × 191 px |
| Article cover | 1200 × 644 px |
YouTube image sizes
| Format | Dimensions |
| Video thumbnail | 1280 × 720 px (minimum), 1920 × 1080 recommended |
| Channel banner (desktop) | 2560 × 1440 px (safe area: 1546 × 423 px) |
| Channel profile picture | 800 × 800 px |
The YouTube banner safe area (1546×423) is critical, this is the only portion guaranteed to be visible on all devices. Keep text and logos within this area.
TikTok image sizes
| Format | Dimensions |
| Profile picture | 200 × 200 px |
| Video (standard) | 1080 × 1920 px (9:16) |

Universal best practices
- Format: JPEG for photos, PNG for graphics with text or transparency
- Quality: export at JPEG 85–90 before uploading to minimise double-compression artifacts
- File size limit: most platforms accept up to 8–30 MB but re-compress anything above ~500 KB
- Colour space: use sRGB. CMYK profiles cause colour shifts on social platforms
Key takeaway: Always prepare images at the platform's recommended dimensions before uploading. Social platforms re-compress every image, uploading at exact dimensions with high JPEG quality (85–90) gives the best result after the platform's compression pass.
