Instagram Image Sizes

Instagram Feed Strategy

Instagram displays images at 1080 pixels wide in the feed, regardless of the original upload size. Images smaller than 1080 pixels will be upscaled and appear blurry, while images larger than 1080 pixels will be downscaled (which is fine). The 4:5 portrait format (1080x1350) occupies the most vertical screen space in the feed, making it the best choice for engagement. A portrait post takes up approximately 30% more screen area than a square post, giving your content more visual dominance as users scroll. For carousel posts, maintain consistent dimensions across all slides to avoid jarring aspect ratio changes between swipes.

Stories and Reels Dimensions

Stories and Reels use the 9:16 vertical format at 1080x1920 pixels. This fills the entire phone screen edge to edge. When designing story images, keep critical content within the center 1080x1420 area, because the top 200 pixels are partially obscured by the username bar and the bottom 300 pixels can be covered by swipe-up links, stickers, and engagement UI elements. Text and key visual elements should never extend into these danger zones, or they will be partially hidden by platform UI overlays on viewers' devices.

Facebook Image Sizes

Facebook Shared Images and Link Previews

When you share a link on Facebook, the Open Graph image displays at 1200x630 pixels (1.91:1 aspect ratio). This is the same aspect ratio used by Twitter cards and LinkedIn link previews, making 1200x630 the single most versatile social media image size. If you can only create one social sharing image, make it 1200x630 and it will work acceptably across Facebook, Twitter/X, and LinkedIn. Images smaller than 600x315 will display as tiny thumbnails rather than large-format previews, dramatically reducing click-through rates. Always ensure your OG images meet the minimum size to trigger the large preview format.

Cover Photo Responsive Behavior

Facebook cover photos present a unique challenge because they display at different crops on desktop (820x312) and mobile (640x360). The safe zone where content is visible on both devices is approximately the center 640x312 area. Avoid placing critical text, logos, or calls to action near the edges, as they will be cropped on one device or the other. Design your cover photo with the understanding that different viewers will see slightly different crops depending on their device and browser window size.

Twitter/X Image Sizes

Twitter/X Feed Image Display

Twitter/X displays images in the feed with a 16:9 crop by default. Images with different aspect ratios are center-cropped to fit the 16:9 preview window. When a user clicks to expand, they see the full image. This means the most important content in your image should be centered within the 16:9 safe zone, even if your full image has a different aspect ratio. For photographs, this is usually fine since subjects tend to be centered. For infographics or images with text at the edges, the automatic crop can cut off critical information. Upload at exactly 1600x900 or 1200x675 to guarantee your entire image displays without cropping in the feed.

Twitter Card Images

When sharing links, Twitter displays the Open Graph image as a card. Summary cards use a small square thumbnail, while summary_large_image cards use the full 1.91:1 aspect ratio at 1200x628 pixels. The large image card provides significantly more visual impact and higher click-through rates. Specify the twitter:card meta tag as "summary_large_image" in your HTML to enable the larger format. The image must be at least 300x157 pixels and no larger than 4096x4096, but 1200x628 is the optimal target size.

LinkedIn, TikTok, YouTube, and Pinterest

LinkedIn

LinkedIn post images display best at 1200x627 pixels (1.91:1 aspect ratio). Company page cover photos are 1584x396 pixels. LinkedIn is a professional platform where image quality signals credibility. Blurry or poorly-cropped images undermine professional authority more on LinkedIn than on any other platform. For shared articles, the link preview image (1200x627) is pulled from the page's Open Graph tags. Document carousels (PDF uploads) should use 1080x1080 or 1080x1350 slides for optimal display in the feed.

TikTok

TikTok content is primarily video, but the video cover image (displayed in your profile grid) is 1080x1920 pixels in 9:16 format. This cover image is the first impression viewers get when browsing your profile, so it should clearly communicate the video's content. Profile photos are 200x200 pixels displayed as circles. TikTok photo carousels (a newer format) use vertical images at 1080x1920 for maximum screen coverage.

YouTube

YouTube thumbnails are critically important for click-through rate and should be 1280x720 pixels (16:9). The best thumbnails use high contrast, large faces with expressive emotions, bold text with 3-4 words maximum, and bright colors that stand out in a grid of competing thumbnails. Channel banners are 2560x1440 pixels but display at dramatically different crops across TV (full size), desktop (2560x423), tablet, and mobile. The safe area for text and logos is the center 1546x423 pixels, which is visible on all devices.

Pinterest

Pinterest strongly favors vertical images. Standard pins at 1000x1500 (2:3 aspect ratio) perform well, but long pins at 1000x2100 (or even taller) get more screen space and higher engagement. Pinterest's feed is a masonry layout where taller pins dominate visually. However, extremely tall pins (beyond 1:3 ratio) are truncated in the feed with a "see more" overlay. The sweet spot is 2:3 to 1:2.5 aspect ratio. Board covers display at 800x450 pixels and should clearly represent the board's theme with bold, recognizable imagery.

Image Optimization Tips for Social Media

Format Selection

JPEG is the best format for photographs on social media due to its superior compression-to-quality ratio. A well-compressed JPEG at quality 80-85% produces files 3-5 times smaller than PNG with virtually imperceptible quality loss for photographic content. PNG should be used for graphics with sharp text, logos, screenshots, or images requiring transparency. WebP offers better compression than both JPEG and PNG, and most social platforms now accept it, but JPEG remains the safest universal choice. Avoid uploading TIFF, BMP, or RAW files — platforms will reject them or recompress them aggressively.

Color Space Considerations

Upload images in sRGB color space. Social media platforms display images in sRGB, and images in Adobe RGB or ProPhoto RGB color spaces will be converted automatically, often resulting in washed-out or shifted colors. If you edit in a wide color space, convert to sRGB as the final step before uploading. This is especially important for product photography where accurate color representation directly affects customer expectations and satisfaction.

Compression Before Upload

Every social platform re-compresses uploaded images using their own algorithms. Facebook's compression is notoriously aggressive, often reducing quality visibly on images with fine gradients or text. To minimize double-compression artifacts, upload at the highest quality your file size allows. For Facebook, images under 100KB sometimes receive less aggressive re-compression. For Instagram, PNG uploads sometimes preserve quality better than JPEG because Instagram's compression pipeline handles PNG input more carefully. Test both formats with your specific image content to determine which produces better results after the platform's processing.
