Ideal image sizes and formats for Social Media

Posting a cropped, pixelated or wrongly proportioned image on social media is one of the most common and damaging mistakes content creators and brands make. Each platform has specific dimensions that, when ignored, result in automatic cropping that hides important parts of the image, black edges that convey amateurishness, or excessive compression that destroys visual quality.
