Social Media Image Size Guide for Clean Posts
Why image sizes matter on social media
Each social media platform displays images at specific dimensions and aspect ratios. When you upload an image that does not match these dimensions, the platform automatically crops or resizes it, often cutting off important content, squishing the image, or adding black bars. The result looks unprofessional and reduces engagement.
Taking a few extra seconds to prepare your image at the correct size before uploading makes the difference between a polished post and one that looks careless. This is especially important for business accounts, product promotions, and brand content where visual quality directly affects credibility.
Instagram image sizes
Instagram supports three main feed post sizes: square at 1080 by 1080 pixels, portrait at 1080 by 1350 pixels, and landscape at 1080 by 566 pixels. Portrait format takes up the most vertical space in the feed, which tends to increase engagement because the image dominates the screen on mobile devices.
Instagram Stories and Reels use a 9:16 ratio at 1080 by 1920 pixels. Profile photos are displayed in a circle at 320 by 320 pixels but should be uploaded at higher resolution for clarity. Instagram automatically compresses uploaded images, so starting with a high-quality file helps maintain the best possible appearance.
Facebook image sizes
Facebook feed images work best at 1200 by 630 pixels for link previews and shared posts. Square images at 1200 by 1200 pixels also display well in the feed. Facebook cover photos should be 820 by 312 pixels for desktop and 640 by 360 pixels for mobile, but since the display differs between devices, keep important content centered.
Facebook Stories use the same 1080 by 1920 pixel format as Instagram Stories. Event cover photos use a 16:9 ratio at 1920 by 1080 pixels. Group cover photos display differently on mobile and desktop, so test on both devices.
YouTube, LinkedIn, and X (Twitter) sizes
YouTube thumbnails should be 1280 by 720 pixels at a 16:9 ratio. This is one of the most important images for video performance because the thumbnail is what viewers see before deciding to click. Channel art should be 2560 by 1440 pixels, but the safe area for text and logos is only 1546 by 423 pixels in the center.
LinkedIn feed images work best at 1200 by 627 pixels. LinkedIn profile banners should be 1584 by 396 pixels. For company page images, use 1128 by 191 pixels for the banner.
X (formerly Twitter) displays images at a 16:9 ratio in the feed. In-stream photos work best at 1600 by 900 pixels. Header photos should be 1500 by 500 pixels. Profile photos are displayed in a circle, so keep the subject centered.
TikTok and Pinterest sizes
TikTok profile photos should be at least 200 by 200 pixels. Video thumbnails and cover images display at 1080 by 1920 pixels in the 9:16 format. Since TikTok is primarily a video platform, the main image concern is the cover frame and profile picture.
Pinterest pins perform best with a 2:3 aspect ratio at 1000 by 1500 pixels. Longer pins are possible but may be truncated in the feed. Square pins at 1000 by 1000 pixels also work but get less feed visibility than vertical pins.
Creating one image for multiple platforms
The most efficient approach is to shoot or design your image with enough space around the subject to allow different crops. Start with a high-resolution original at least 2000 pixels wide, then create platform-specific versions by cropping to each required ratio.
Save each version with a clear naming convention: product-launch-instagram-square.jpg, product-launch-facebook-link.jpg, product-launch-youtube-thumb.jpg. This prevents confusion about which version goes where and makes it easy to find the right file for each platform.
Preview before publishing
Always preview your image on a mobile device before publishing. Social media is consumed primarily on phones, and an image that looks great on your desktop monitor may have text that is too small, details that are too fine, or composition that feels too tight on a phone screen.
Many social media scheduling tools show a preview of how your post will appear in the feed. Use these previews to catch sizing issues before your audience sees them.
