Social Media Image Sizes 2026: The Complete Guide (Instagram, YouTube, LinkedIn, TikTok)
Why Image Sizes Matter on Social Media
Every social platform optimizes its feed for specific aspect ratios. If you upload an image with the wrong dimensions, the platform's algorithm automatically crops it ā often removing your subject, cutting off your text overlay, or leaving awkward white borders. Beyond aesthetics, wrong-sized images can hurt algorithmic reach: Instagram and TikTok have confirmed they prioritize content that natively matches their recommended formats, and YouTube thumbnails at the correct 16:9 ratio receive better click-through rate signals than incorrectly sized alternatives.
Instagram Image Sizes 2026
| Format | Dimensions | Aspect Ratio | Max File Size |
|---|---|---|---|
| Square Post | 1080 Ć 1080 px | 1:1 | 8 MB |
| Portrait Post | 1080 Ć 1350 px | 4:5 | 8 MB |
| Landscape Post | 1080 Ć 566 px | 1.91:1 | 8 MB |
| Story / Reel | 1080 Ć 1920 px | 9:16 | 8 MB |
| Profile Picture | 320 Ć 320 px | 1:1 (circle crop) | ā |
Pro tip: Portrait (4:5) posts take up more vertical screen real estate in the feed, resulting in higher visibility and typically 15-20% higher engagement than square posts. Use DCPIXEL's Instagram Portrait Resizer to resize any image to 1080Ć1350px instantly.
