Social Media Image Sizes: The Complete 2025 Guide
Uploading the wrong image size to social media means your content gets cropped in unexpected places, stretched, or blurred after the platform recompresses it. This guide gives you the exact dimensions you need for every major platform in 2025—without all the guesswork.
Why Getting Image Sizes Right Matters
Every social media platform displays images inside specific containers. When your image doesn't match those containers, the platform auto-crops or stretches it—and the result often looks unprofessional. Cover photos lose important elements, profile pictures crop out faces, and post images display poorly on mobile.
Beyond cropping, all major platforms recompress images when you upload them. If your original file is already heavily compressed or too small, the platform's additional compression stacks on top and produces visibly blurry, artifact-filled results. Uploading at the recommended dimensions with reasonable file sizes gives the platform's algorithm the best source material to work with.
Use ImageHub's resize tool to quickly resize any image to the exact pixel dimensions required for each platform before uploading.
📸 Instagram Image Sizes
Instagram is primarily a visual platform, making correct image dimensions especially important. Instagram stores images at up to 1080px wide—uploading larger images just gets them downsized, while uploading smaller images gets them stretched and blurred.
Profile Picture
110 × 110 pxMinimum 320 × 320 px recommended (displayed as circle). Upload at least 320 × 320 px to prevent blurring. Center your face or logo—edges are cropped.
Square Post
1080 × 1080 pxThe classic Instagram format. Ratio 1:1. Displayed at 600px on desktop and up to 1080px on high-resolution mobile screens.
Portrait Post
1080 × 1350 pxRatio 4:5. Takes up more vertical space in the feed, giving you more visual real estate per post. The most popular format for fashion and product posts.
Landscape Post
1080 × 566 pxRatio 1.91:1. Good for panoramic shots and scenes. Shows less of the image in the grid—use portrait or square for better grid aesthetics.
Stories / Reels
1080 × 1920 pxRatio 9:16 (full-screen vertical). Keep important elements in the center 1080 × 1420 px area to avoid overlap with UI elements (profile name, stickers area).
📘 Facebook Image Sizes
Profile Picture
170 × 170 pxUpload at minimum 170 × 170 px. Displays as 170 × 170 on desktop and 128 × 128 on smartphones. Displayed as circle on your profile, but stored as square.
Cover Photo
851 × 315 pxDisplays at full width on desktop (851px) and 640px on mobile with automatic cropping. Design with key elements in the center 640 × 315 px to ensure they show on all devices.
Shared Link / Post Image
1200 × 630 pxRatio 1.91:1. Used for Open Graph previews when sharing links. Also the standard size for regular photo posts displayed in the feed.
Stories
1080 × 1920 pxSame as Instagram Stories. Full-screen vertical format, ratio 9:16. Facebook and Instagram stories are cross-posted, so one file works for both.
𝕏 X (Twitter) Image Sizes
Profile Picture
400 × 400 pxRecommended 400 × 400 px minimum. Displayed at 48 × 48 px in feeds and at larger sizes on your profile page. Displayed as a circle.
Header / Banner
1500 × 500 pxRatio 3:1. The banner appears behind your profile picture. The bottom portion (roughly 60px) and side edges may be cropped on smaller screens. Keep important content centered.
Tweet / Post Image
1200 × 675 pxRatio 16:9 for inline feed display. X automatically crops to a preview in the feed—images display differently based on single vs. multiple image posts. 1200 × 675 px is the safest single-image choice.
💼 LinkedIn Image Sizes
Personal Profile Picture
400 × 400 pxMinimum 200 × 200 px, recommended 400 × 400 px or larger. Square 1:1 ratio. Professional headshot with neutral or simple background. Displayed as circle in feeds.
Personal Background Banner
1584 × 396 pxRatio 4:1. The horizontal banner behind your profile picture. Keep text and key elements in the center-right area, as the profile picture overlaps the lower-left corner.
Company Page Logo
300 × 300 pxSquare 1:1 ratio. Appears in search results, articles, and feed posts. Use a clean, centered logo—it displays very small in many contexts.
Post / Shared Image
1200 × 627 pxRatio ~1.91:1 for standard posts. LinkedIn also supports vertical (4:5) and square (1:1) images. For maximum feed real estate and engagement, 1200 × 627 px or a 1:1 square work best.
▶️ YouTube Image Sizes
Video Thumbnail
1280 × 720 pxRatio 16:9. Minimum 640 × 360 px. Maximum file size 2 MB. Custom thumbnails are one of the most impactful factors for click-through rate on YouTube—make text readable at small sizes.
Channel Banner / Art
2560 × 1440 pxThe large banner is displayed differently across TV (2560 × 1440), desktop (2560 × 423), tablet (1855 × 423), and mobile (1546 × 423). Design within the safe area of 1546 × 423 px centered to ensure visibility everywhere.
Channel Profile Picture
800 × 800 pxDisplays in circular frame across YouTube. Upload at 800 × 800 px for best quality. This photo is shared with your Google account profile picture.

Pro Tips for Social Media Images
- ✓ Upload JPG (not PNG) for photos – social platforms recompress all images; starting with JPG reduces double-compression quality loss.
- ✓ Use the 1:1 square format on Instagram – it takes up the most grid space and looks consistent across all devices.
- ✓ Keep text within the safe zone – most platforms crop at the edges on smaller screens. Place text and logos in the center 80% of the image.
- ✓ Use 1200 × 630 for link sharing – this is the Open Graph standard used by Facebook, LinkedIn, and most messaging apps when generating link previews.
- ✓ Don't over-compress before uploading – platform compression adds to yours. Use quality 85–90 for social uploads, not the web-optimized 75–80 you'd use for your own site.
