You design a nice post, publish it, and find the platform has cropped the edges or compressed it until the text is blurry. Usually the image wasn’t prepared at the right ratio. The key isn’t memorizing dozens of numbers — it’s understanding aspect ratios.
The essential aspect ratios
- 1:1 (square): safe for feed posts on most platforms.
- 4:5 (portrait): takes more screen space on phones; great for Instagram and Facebook posts.
- 9:16 (full vertical): stories, reels, TikTok and Shorts.
- 16:9 (landscape): YouTube thumbnails, presentations and wide screens.
- About 1.91:1: link preview images when sharing an article.
Commonly used sizes
| Use | Ratio | Suggested pixels |
|---|---|---|
| Square post | 1:1 | 1080 × 1080 |
| Portrait post | 4:5 | 1080 × 1350 |
| Story / reel / TikTok | 9:16 | 1080 × 1920 |
| YouTube thumbnail | 16:9 | 1280 × 720 |
| Link preview | ≈1.91:1 | 1200 × 630 |
Platforms update their layouts regularly, so check each one’s help center when you need an exact size, especially for cover images.
The safe zone
In stories and reels, like and comment buttons and the account name cover the screen edges. Keep important text and your logo in the middle, away from the top and bottom. Profile pictures are usually shown as circles, so avoid important elements in the corners.
One image, many platforms
- Start with a large, high-resolution image with the main subject centered.
- Use Crop Image and pick the ratio for each platform.
- Set the pixel dimensions with the Image Resizer.
- Compress with the Image Compressor before uploading.
Why does my image look blurry?
- You uploaded a small image and the platform enlarged it.
- You uploaded a huge image and the platform compressed it heavily.
- The text is too small relative to the image.
The fix: upload close to the recommended size and keep text large and clear. If your original is small, try the Image Upscaler.
Bottom line
Remember four ratios — 1:1, 4:5, 9:16 and 16:9 — keep key content centered, and prepare a version for each platform instead of relying on automatic cropping.
