How to Resize Images for Social Media: The Complete Size Guide
Every social platform has different image size requirements. Get the exact dimensions for Instagram, Facebook, Twitter, LinkedIn, and more.
You've taken the perfect photo, edited it, and you're ready to post. Then Instagram crops it awkwardly, Facebook stretches it, and LinkedIn compresses it into a pixelated mess. The problem isn't your photo — it's the dimensions.
Every social media platform has specific image size requirements. Posting the right dimensions means your images display perfectly without cropping, stretching, or quality loss. Here's the complete guide to resizing images for social media in 2025.
Instagram Image Sizes
| Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Square Post | 1080 x 1080 | 1:1 |
| Portrait Post | 1080 x 1350 | 4:5 |
| Landscape Post | 1080 x 566 | 1.91:1 |
| Story / Reel | 1080 x 1920 | 9:16 |
| Profile Picture | 320 x 320 | 1:1 |
Instagram displays images at 1080px wide. Uploading larger images works but they get downscaled. Uploading smaller images gets upscaled, which looks blurry. The 4:5 portrait format gets the most screen real estate in the feed — use it for maximum visibility.
Facebook Image Sizes
| Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Feed Post | 1200 x 630 | 1.91:1 |
| Cover Photo | 820 x 312 | 2.63:1 |
| Profile Picture | 170 x 170 | 1:1 |
| Event Cover | 1200 x 628 | 1.91:1 |
| Story | 1080 x 1920 | 9:16 |
Facebook heavily compresses uploaded images. To minimize compression artifacts, upload at exactly the recommended dimensions and pre-compress your images to under 100KB. This gives Facebook's algorithm less work to do and results in sharper output.
Twitter/X Image Sizes
| Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| In-Stream Photo | 1200 x 675 | 16:9 |
| Header Photo | 1500 x 500 | 3:1 |
| Profile Picture | 400 x 400 | 1:1 |
LinkedIn Image Sizes
| Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Feed Post | 1200 x 627 | 1.91:1 |
| Banner Image | 1584 x 396 | 4:1 |
| Profile Photo | 400 x 400 | 1:1 |
| Company Logo | 300 x 300 | 1:1 |
Pinterest & TikTok
Pinterest favors tall images: 1000 x 1500px (2:3 ratio) performs best. TikTok thumbnails are 1080 x 1920px (9:16). Both platforms reward properly sized content with better distribution.
How to Resize Without Losing Quality
The key to good resizing is maintaining aspect ratio. Stretching a 1:1 image to 16:9 distorts it. Instead, crop to the target aspect ratio first, then resize to the exact pixel dimensions.
ConvertMinify's resize tool handles this automatically. The aspect ratio lock prevents distortion, and the crop tool lets you select exactly the area you want before resizing.
Optimization Tips for Social Media
- Resize first, compress second. Get the dimensions right, then use the JPG compressor to optimize file size.
- Use the right format. JPG for photos, PNG for graphics with text. Platforms accept both.
- Pre-compress to avoid platform recompression. Uploading an already-optimized image means the platform's compression algorithm has less to do, resulting in better output quality.
- Test on mobile. Most social browsing happens on phones. Check how your images look at mobile dimensions.
