1. Instagram Image Sizes
Instagram supports multiple post types with different dimensions.
Instagram Dimensions
| Post Type | Dimensions | Aspect Ratio | Notes |
|---|---|---|---|
| Square post | 1080 x 1080 px | 1:1 | Most common |
| Portrait | 1080 x 1350 px | 4:5 | Highest engagement |
| Landscape | 1080 x 566 px | 1.91:1 | Good for wide shots |
| Story / Reels | 1080 x 1920 px | 9:16 | Full screen vertical |
| Profile picture | 320 x 320 px | 1:1 | Rendered as circle |
| Carousel | 1080 x 1080 px | 1:1 | Maximum 10 slides |
Instagram Best Practices
Portrait (4:5) images get 38% more engagement than square posts. Always use the highest resolution available and let Instagram compress it.
2. TikTok Image and Video Sizes
TikTok is designed for vertical mobile viewing.
TikTok Dimensions
| Content Type | Dimensions | Aspect Ratio | Notes |
|---|---|---|---|
| Video | 1080 x 1920 px | 9:16 | Standard vertical |
| Thumbnail | 1080 x 1920 px | 9:16 | Auto-generated |
| Profile photo | 200 x 200 px | 1:1 | Circular crop |
| Image post | 1080 x 1920 px | 9:16 | Full screen |
TikTok videos should always be shot or resized to 9:16. Horizontal videos will have letterboxing (black bars).
3. YouTube Image Sizes
YouTube has specific requirements for every visual element.
YouTube Dimensions
| Asset | Dimensions | Aspect Ratio | File Size Limit |

YouTube Thumbnail Tips
Thumbnails should be 1280 x 720 px minimum. Use bright colors, readable text, and a clear focal point. Channels with custom thumbnails see 30–40% more clicks than those without.
4. X (Twitter) Image Sizes
Twitter displays images in multiple contexts.

Tall pins (2:3 ratio) perform best on Pinterest. They take up more screen space in the feed and get more clicks.
8. How to Resize Images Without Losing Quality
Resizing an image usually reduces quality. Here is how to maintain sharpness.
Resizing Best Practices
- Start with the largest source image possible
