Social Media Image Sizes

Social media image sizes at a glance

Here are the main image sizes for eight networks in one table; TikTok and Pinterest aren't covered yet. Where a network publishes no size, the table says so.

LinkedIn image sizes

LinkedIn recommends 1584 × 396 pixels for the cover image on a profile and 1,080 pixels wide for images in posts, in any shape from 3:1 to 4:5. A Company Page cover is 1512 × 256 and its logo 400 × 400. The LinkedIn image sizes page has LinkedIn's other placements, from articles and events to groups, and the archived history of the Company Page cover.

Instagram image sizes

Instagram keeps a photo 1080 pixels wide at any shape from 1.91:1 to 3:4: 1080 × 566 for landscape, 1080 × 1080 for a square and 1080 × 1440 for the tallest portrait. Meta's publishing API, which apps and scheduling tools use to post to business and creator accounts, still stops at 4:5 (1080 × 1350). Instagram publishes no size for an ordinary Story or a profile photo. The Instagram post size page covers carousels, Stories, Reels and Reel covers.

Facebook image sizes

Facebook's help page gives a Page profile picture 320 × 320 pixels for best quality; it is cropped to a circle and shown at 176 × 176 on computers and 196 × 196 on smartphones. A Page cover photo must be at least 400 × 150 and loads fastest as an sRGB JPG of 851 × 315 pixels under 100 kilobytes. Computers show the cover at 16:9 and phones at 2.4:1, and the profile picture covers part of its left side. For a logo or text, Facebook suggests a PNG file.

For a shared link, Meta's sharing guide recommends an image of at least 1200 × 630 pixels and accepts images from 200 × 200 up to 8 MB. Facebook publishes no size for ordinary images in the feed. Meta's Ads Guide gives 1440 × 1800 (4:5) for a feed ad and 1440 × 2560 (9:16) for a Story ad, each a JPG or PNG of up to 30 MB.

X (Twitter) image sizes

X recommends 400 × 400 pixels for a profile photo, under 2 MB, and 1500 × 500 for the header; both can be JPG, GIF or PNG, but not animated. Depending on the screen, up to 60 pixels at the top and bottom of the header can be cut off.

X gives no pixel size for images in posts: a photo can be up to 5 MB, a post holds up to four, and a single photo between 2:1 and 3:4 shows uncropped. X's help pages block automated requests, so these sizes were read from archived copies made between August and October 2026.

Threads image sizes

Meta publishes no image size for Threads in its help pages. The Threads API takes JPEG and PNG images of up to 8 MB at a shape of up to 10:1 and scales them to between 320 and 1440 pixels wide. The cropper has no Threads size; Instagram's post sizes fit inside these limits.

Bluesky image sizes

Bluesky publishes no image sizes. Its open-source app crops an avatar square and a banner to 3:1, and Bluesky's image server serves them at 1000 × 1000 and 3000 × 1000 pixels, the sizes the cropper uses. An avatar or banner can be a PNG or JPEG of up to 1,000,000 bytes, and the app shrinks a larger one before it uploads it. A standard post holds up to four images of up to 2 MB each; Bluesky's app sends five to ten as a gallery.

Mastodon image sizes

Mastodon's documentation says an avatar is downscaled to 400 × 400 pixels and a header to 1500 × 500, each a WEBP, PNG, GIF or JPG file of up to 2 MB; Mastodon 4.6 and later accept 8 MB. Images in posts can be up to 16 MB, up to four per post, and are downscaled to 8.3 megapixels, enough for 3840 × 2160. Every server runs its own version and limits, so check yours.

YouTube image sizes

YouTube recommends 3840 × 2160 pixels for a video thumbnail, at 16:9 and at least 640 pixels wide, and 2160 × 3840 for a Shorts thumbnail, as a JPG or PNG. A thumbnail can be up to 2 MB on mobile and 50 MB on a computer.

A channel banner should be 2560 × 1440 pixels, at least 2048 × 1152 at 16:9 and up to 6 MB. The same banner is used on computers, phones and TVs and is cropped on some, so YouTube gives a safe area for text and logos: 1235 × 338 at the minimum size. The cropper scales that safe area to the 2560-wide banner, 1544 × 423, and marks it on the frame. A profile picture renders at 98 × 98 pixels and can be up to 15 MB; YouTube recommends no upload size for it.

How to crop an image for social media

The cropper above saves your image at exactly the size you choose, without uploading it anywhere.

1. Choose the network and the size, for example an X header.
2. Choose an image, or drop it on the frame.
3. Drag the image or use the sliders to frame it, and zoom in to crop tighter.
4. Choose JPG or PNG, then download the file and upload it on the network.

If the part you chose has fewer pixels than the size, the cropper warns that it will enlarge the image, which can make it look blurry. Zoom out, or use a larger image.
