Best Image Sizes for Social Media in 2026
Updated July 16, 2026
Instagram displays feed images at up to 1080 pixels wide. Uploading larger images causes Instagram to downscale server-side, which softens edges - export at the exact target size for the sharpest result.
- Feed square: 1080x1080 (1:1).
- Feed portrait: 1080x1350 (4:5). Takes the most feed real estate.
- Feed landscape: 1080x566 (1.91:1).
- Story / Reel: 1080x1920 (9:16).
- Profile picture: 320x320 minimum; upload 1080x1080 for future-proofing.
X (Twitter)
X supports up to 4 images per post, displayed at different aspect ratios depending on how many are attached.
- Single-image post: 1600x900 (16:9) or 1200x675.
- Header: 1500x500.
- Profile picture: 400x400.
LinkedIn shows link previews using the same og:image logic as most social platforms. A 1200x627 landscape image renders correctly for both single posts and shared links.
- Post / link preview: 1200x627 (1.91:1).
- Company page cover: 1128x191.
- Personal background: 1584x396.
- Profile picture: 400x400.
Facebook uses similar link-preview logic to LinkedIn but is less strict about aspect ratio. 1200x630 is the safe universal size.
- Post / link preview: 1200x630.
- Cover photo: 820x312 desktop, 640x360 mobile.
- Profile picture: 170x170 displayed, upload 320x320+.
TikTok, YouTube, Pinterest
The three platforms use very different orientations. TikTok is vertical-first, YouTube is landscape, and Pinterest favors tall portrait pins that dominate its grid.
- TikTok video / cover: 1080x1920 (9:16).
- TikTok profile: 200x200.
- YouTube thumbnail: 1280x720 (16:9). 2 MB max.
- YouTube channel banner: 2560x1440 (safe area 1546x423).
- Pinterest standard pin: 1000x1500 (2:3). Taller pins get cropped in the feed.
- Pinterest profile: 165x165.
Export tips that apply to every platform
Always export at the exact target size instead of relying on the platform to downscale a larger source - server-side downscaling is usually softer than your local export. Use WebP or JPEG at quality 85 for photos, and keep files under 1 MB whenever possible so previews load fast on mobile.
Frequently asked questions
What is the best image size for Instagram in 2026?
1080x1080 for square feed posts and 1080x1350 for portrait feed posts. Stories and Reels use 1080x1920. Instagram downscales anything larger, so export at these exact dimensions.
What size should a YouTube thumbnail be?
1280x720 pixels (16:9 aspect ratio), under 2 MB in JPG or PNG. YouTube compresses uploads, so start with a sharp source and use quality 85+.
What is the best image size for LinkedIn posts?
1200x627 pixels (1.91:1). This is the standard link-preview size that renders cleanly for both direct image posts and shared URLs.
How big should a Pinterest pin be?
1000x1500 pixels (2:3 aspect ratio). Taller pins get cropped in the feed, and shorter pins take up less space and get fewer clicks.
