Social media image size reference 2024
Each platform has specific optimal image dimensions for different placements. Using the wrong size leads to compression artifacts, unwanted cropping, or letterboxing. Instagram feed posts display at 1080px wide, with square (1:1), portrait (4:5), and landscape (1.91:1) supported. Profile pictures display as circles; upload at least 180×180 and center the key element. Twitter/X profile pictures should be at least 400×400; the header is 1500×500. LinkedIn profile photos display at 400×400; the background banner at 1584×396. YouTube thumbnails should be 1280×720 (16:9).
| Platform | Placement | Optimal size | Aspect ratio |
|---|---|---|---|
| Square post | 1080×1080 | 1:1 | |
| Portrait post | 1080×1350 | 4:5 | |
| Story/Reel | 1080×1920 | 9:16 | |
| Twitter/X | Post image | 1600×900 | 16:9 |
| Article header | 1200×628 | 1.91:1 | |
| YouTube | Thumbnail | 1280×720 | 16:9 |
Crop modes and focal point selection
When resizing an image to a different aspect ratio, you must choose how to handle the mismatch. Center crop removes edges from all sides to fill the target ratio — best when the subject is centered. Fit with padding scales the image to fit entirely within the target dimensions and adds colored bars (letterbox/pillarbox) to fill gaps — best when you can't lose any part of the image. Stretch-to-fill distorts the image to exactly match dimensions — acceptable only for abstract backgrounds. For portraits, use face-detection focal point to keep the face centered in the crop area.
Glossary
- Aspect ratio
- The proportional relationship between width and height (e.g., 16:9, 4:5, 1:1).
- Letterboxing
- Horizontal black/white bars added above and below an image when its aspect ratio is wider than the display area.
- Pillarboxing
- Vertical bars added to the sides of an image when it's narrower than the display area.
- Focal point
- The most important part of an image (often a face or product) that should remain visible after cropping.
