示例
Prepare Instagram content
Check that your feed post is 1080x1080 (square) or 1080x1350 (portrait, the best for engagement). Stories and Reels need 1080x1920 vertical format.
Design a YouTube thumbnail
YouTube recommends 1280x720 (16:9) thumbnails, max 2MB. Use JPG or PNG. The thumbnail is the single biggest factor in click-through rate.
Create LinkedIn post graphics
Shared images on LinkedIn perform best at 1200x627 (1.91:1 ratio). Article cover images should be 1200x644. Keep file size under 5MB.
Frequently asked questions
Do I need to use the exact pixel dimensions?
Not always. Most platforms resize images automatically, but using the recommended dimensions ensures maximum quality with no cropping. Match the aspect ratio at minimum.
What image format should I use?
JPG works for photos, PNG for graphics with text or transparency. Some platforms also accept WebP. Avoid BMP and TIFF as they result in unnecessarily large files.
How often do social media image sizes change?
Platforms update dimensions occasionally, usually once or twice per year. Profile photos and post images change rarely. New features like Reels or Shorts may introduce new sizes. This guide is updated for 2026.
What is the best aspect ratio for engagement?
Vertical content (9:16 or 4:5) generally gets the most engagement because it takes up more screen space on mobile devices. For feed posts, 4:5 (1080x1350) is optimal on Instagram. For videos, 9:16 (1080x1920) is standard across Stories, Reels, Shorts, and TikTok.
Can I use the same image across all platforms?
A 1200x630 image works across Facebook, LinkedIn, and X for shared links. However, each platform has different optimal sizes for feed posts, stories, and ads. For best results, resize per platform.
