Aspect ratio reference
1:1 aspect ratio: sizes in pixels and where it is used.
1:1 means 1 units wide for every 1 tall, a decimal of 1. At 1080 pixels wide that is 1080 by 1080; at 1920 wide, 1920 by 1920. Square posts, profile pictures, album art and carousel slides on every platform.

Instagram Square Post
1080 x 1080 pixels. A square post is 1080 by 1080 pixels.
Size guideInstagram Profile Picture
320 x 320 pixels. Instagram stores the profile picture at 320 by 320 pixels and draws it as a circle: about 110 pixels across on your profile in the app, 150 on the web, and as small as 32 pixels next to a comment or on a Story ring.
Size guideFacebook Profile Picture
720 x 720 pixels. Facebook draws a Page or personal profile picture as a circle, about 170 pixels across on a computer, 128 on a phone and roughly 40 pixels beside every post and comment.
Size guideLinkedIn Profile Picture
400 x 400 pixels. LinkedIn's help page states that a profile photo has to be between 400 by 400 and 7680 by 4320 pixels, under 8 MB, in PNG or JPG, and that GIFs are not supported.
Size guideX Profile Picture
400 x 400 pixels. 400 by 400 pixels is the widely published size for an X profile picture, and the 2 MB file limit is the figure X's help pages have carried for years.
Size guidePinterest Square Pin
1000 x 1000 pixels. A square pin is 1000 by 1000 pixels: Pinterest's recommended 1000-pixel pin width with the height matched to it.
Size guidePinterest Board Cover
600 x 600 pixels. A board cover is not a separate upload.
Size guideTikTok Profile Picture
400 x 400 pixels. TikTok's support article on adding a profile photo redirected to a page that could not be read when this guide was checked, and TikTok publishes no pixel recommendation we were able to confirm.
Size guideYouTube Profile Picture
800 x 800 pixels. YouTube's channel branding page asks for a JPG, GIF, BMP or PNG without animation, under 15 MB, that renders at 98 by 98 pixels.
Size guideYouTube Community Post
1080 x 1080 pixels. YouTube's help page on creating posts says you can attach up to 10 images as JPG, PNG, GIF or WEBP at up to 16 MB each, and suggests a 1:1 ratio because that is how images are shown in the feed.
Size guideWhatsApp Profile Picture
500 x 500 pixels. WhatsApp's help page on editing your profile could not be read when this guide was checked, so the figures here are the widely published ones rather than confirmed requirements: a minimum of about 192 by 192 pixels to avoid a visibly poor picture, and no HD option for profile photos.
Size guideGoogle Business Profile Logo
720 x 720 pixels. Google's photo and video guidelines give a recommended resolution of 720 by 720 pixels and a minimum of 250 by 250, as JPG or PNG between 10 KB and 5 MB, and those rules apply to the logo slot directly.

About the 1:1 ratio
1:1 is the square. Width equals height, so the decimal is 1.0 and there is nothing to simplify: 1080 by 1080 pixels, 800 by 800 and 500 by 500 are all the same shape. It is the only ratio with no orientation, which is why platforms fall back to it for anything that has to fit a fixed slot, such as profile pictures, app icons and album art.
Instagram launched square-only in 2010 and 1:1 is still accepted everywhere: Instagram, Facebook, LinkedIn, Threads and X feed posts, carousel slides, and Pinterest (which prefers taller). Profile photos on every network are square uploads displayed as a circle. Spotify and Apple Music cover art is square at 3000 by 3000 pixels, and YouTube channel icons are 800 by 800.
Cropping from a square is symmetric. Going to 4:5 you either keep the full height and cut 20 percent of the width (a 1080 square becomes 864 by 1080) or keep the width and add 270 pixels of height. Going to 16:9 keeps 56 percent of the height. Common sizes: 1080 by 1080 for feed posts, 1200 by 1200 for a square link-preview fallback, 400 by 400 for X and LinkedIn profile pictures, 320 by 320 for the Instagram profile picture.
Questions about 1:1
Any size where width equals height: 1080 by 1080 for a feed post, 1200 by 1200 for a square link image, 800 by 800 for a YouTube channel icon, 400 by 400 for an X or LinkedIn profile picture. Pick the width the platform displays at and use the same number for the height.
Yes. Instagram, Facebook, LinkedIn and Threads all display feed images at about 1080 pixels wide on phones, so 1080 by 1080 is the smallest size that stays sharp. Larger squares are downscaled and recompressed on upload; smaller ones are upscaled and look soft.
Every platform crops profile pictures to a circle, and a circle needs a square to sit in. Upload a 1:1 image with the subject centred and nothing important near the corners, since the corners are cut. Instagram shows the picture at 320 by 320 pixels, X and LinkedIn at 400 by 400.
