Social sizes · perfect dimensions for every platform
Exact dimensions for every platform, sized from each platform's current documentation. The crop preview shows what survives and shades what the platform covers, so nothing important lands under a profile photo.

YouTube thumbnails are 3840x2160 (16:9, under 2MB). Crop yours to fit, with the duration badge's corner shown.
Every platform crops. Upload a photo at the wrong shape and the site decides for itself what to keep, which is how heads end up cut off in a LinkedIn banner and how the important half of a YouTube thumbnail disappears behind a duration badge.
Three numbers matter for each one, and only the first is usually published: the pixel dimensions, the aspect ratio those imply, and the file size the uploader will accept. Get the ratio wrong and the platform crops. Get the size wrong and it re-compresses, which is where the blockiness comes from.
The safe zones matter more than the dimensions. A LinkedIn banner is 1584 by 396, but a circular profile photo sits over the lower left of it on desktop and moves on mobile. An Instagram story is 1080 by 1920 with roughly the top and bottom 250 pixels covered by the interface. Sizing correctly and then putting your subject where the platform draws its own furniture is a wasted upload.
Each figure carries the date it was last checked. Platforms change these without announcing it, which is why a table that does not say when it was verified is worth very little.
