Social media image sizes, from each platform's own help pages

Social media image sizes, as the platforms' own help pages gave them on 22 October 2026: a Facebook Page cover photo 851 × 315 pixels, an Instagram post 1080 pixels wide in any shape from 1.91:1 to 3:4, a LinkedIn banner 1584 × 396, an X header 1500 × 500, and a YouTube thumbnail 16:9, ideally 3840 × 2160.

Each size in the table below links to the help page it came from. Where we found no size on a platform's own pages, we say so rather than guess, and where its only figure is for adverts, we say that too. For clips, see social media video sizes and length limits.

Social media image sizes at a glance

Facebook cover photo and post sizes

Facebook's help page on Page profile picture and cover photo dimensions gives the Facebook cover photo size as a minimum and a target, with the profile picture beside it:

• Cover photo: at least 400 × 150 pixels. It loads fastest as an sRGB JPG that is 851 × 315 pixels and under 100 KB.
• Profile picture: 320 × 320 pixels for the best quality. It shows at 176 × 176 pixels on computers and 196 × 196 on smartphones.
• On mobile devices the profile picture overlaps the cover photo by about 40 pixels, so leave room around faces and words rather than filling the cover to its edges.
• For a cover or profile picture with a logo or text, a PNG file may give a better result.

Our resize tool has no Facebook tile, so use Pixels: switch off Keep the proportions and type 851 and 315. If the saved JPG is still over 100 KB, compress the image with Target size, which counts a KB as 1,000 bytes.

Facebook post size

We found no pixel size for a photo in an ordinary post in Facebook's help centre. Its page on photos that will not upload recommends JPEG, BMP, PNG, GIF or TIFF files under 15 MB, and a PNG under 1 MB, because larger PNG files may appear pixelated.

Meta does give a feed size, in its advertising guide. Its ads guide for Facebook Feed images recommends a 4:5 picture of 1440 × 1800 pixels, at least 600 pixels wide, as a JPG or PNG up to 30 MB. That is a sensible target for an upright photo post too, but it is advertising guidance, not a rule for posts.

Instagram post, story and profile picture sizes

Instagram's help page on the image resolution of photos you share says a photo between 320 and 1080 pixels wide keeps its own resolution as long as its shape is between 1.91:1 and 3:4. At 1080 pixels wide, that is any height from 566 to 1440 pixels. A wider photo is reduced to 1080 pixels wide, a narrower one is enlarged to 320, and a shape outside the range is cropped.

Square and upright posts both fit. Our Instagram post size preset makes a 1080 × 1080 square, and the Instagram portrait tile beside it makes 1080 × 1350, a 4:5 shape inside the range.

For stories, we found no size in Instagram's own help centre. Meta's page on design requirements for Instagram Stories ads recommends 1080 × 1920 pixels, a full-screen 9:16, with a minimum of 600 × 1067, as a JPG or PNG up to 30 MB. The Story or Reel tile in our resize tool makes 1080 × 1920.

Nor did we find a profile picture size: Instagram's page on adding or changing your profile picture gives none. A square of at least 320 × 320 pixels is a safe choice. It matches what Facebook asks for a Page's profile picture, and 320 pixels is the narrowest width Instagram keeps a photo at.

LinkedIn banner and post image sizes

LinkedIn's help page on the cover image on your profile recommends 1584 × 396 pixels, a 4:1 strip, as a JPG or PNG file under 8 MB. If the cover looks blurry or pixelated, it suggests choosing an image with a larger file size.

Our LinkedIn banner size preset makes exactly 1584 × 396, cropping the edges to fill the strip or fitting the whole picture on a background colour.

For the LinkedIn post image size, LinkedIn's image specifications for Pages give 1.91:1, or 1200 × 627 pixels, for a custom image in a Page post that carries a link. A post with only an image, or an image and text, is enlarged to fit the feed, and on mobile no image is cropped: other shapes get thin white padding.

For image adverts, LinkedIn's single image ads specifications recommend 1200 × 1200 pixels for a square, 1200 × 628 for landscape and 720 × 900 for a 4:5 vertical picture, as a JPG, PNG or GIF up to 5 MB.

X (Twitter) header and post sizes

X's help page on customising your profile recommends 1500 × 500 pixels for the header, which it also calls a banner, and 400 × 400 for the profile photo. Both can be JPG, GIF or PNG, but not an animated GIF.

Our Twitter header size preset makes 1500 × 500, a 3:1 strip. Few photos start out that shape, so Fill, which keeps the middle, cuts a lot from the top and bottom of most pictures.

For a picture in a post, X gives a shape rather than a size. Its page on posting photos or GIFs says a single photo between 2:1 and 3:4 shows in full, photos can be up to 5 MB, and it accepts GIF, JPEG and PNG files but not BMP, TIFF or other formats.

YouTube thumbnail size

YouTube's help page on adding custom thumbnails asks for a 16:9 picture at least 640 pixels wide and recommends 3840 × 2160 pixels, in a format such as JPG or PNG. The file can be up to 2 MB when you upload from a phone and 50 MB from a computer. For Shorts the shape turns to 9:16, with 2160 × 3840 recommended.

Our YouTube thumbnail size preset makes 1280 × 720: the same 16:9 shape, well above the minimum width, and a far smaller file than 3840 × 2160, which helps with the 2 MB limit on a phone. For the full size, type 3840 and 2160 under Pixels.

Pinterest pin size

Pinterest's page on ad specs recommends a 2:3 shape, 1000 × 1500 pixels, for a standard image Pin, and says these Pins can run in paid campaigns or gain organic impressions. Pins with an aspect ratio greater than 2:3 might get cut off in feeds. The file can be PNG or JPEG, up to 20 MB on a computer and 32 MB in the app.

How to resize a picture to any of these sizes

You can resize an image to any size in this guide in your browser, without uploading it:

• Select your picture, or up to 100 at once for a set of posts.
• Under Resize by, pick Platform size for the Instagram, YouTube, X and LinkedIn tiles, or Pixels for any other size.
• For a size with no tile, such as an 851 × 315 Facebook cover or a 1000 × 1500 Pin, switch off Keep the proportions and type the width and the height.
• If your picture is another shape, choose Fill to crop the edges, Fit to keep all of it on a background colour, or Stretch, which distorts it.
• Keep Save as on Original, or choose JPG or PNG, then press Resize and save the result.

Fill keeps the middle of the picture. If the part you want is somewhere else, crop the picture to the platform's shape first, then resize it. Making a picture bigger than it is makes it softer, and the tool warns you when a size would do that.

JPG or PNG?

Every help page above that names file types lists JPG and PNG, and X takes nothing but GIF, JPEG and PNG, so a WebP picture saved from a website needs converting first. JPG suits photographs and keeps files small; PNG keeps logos and lettering sharp, which is why Facebook suggests it for covers with text. A HEIC photo from a phone is saved as a JPG when you resize it with Save as on Original, or you can convert HEIC to JPG without resizing it.
