Optimizing social media image sizes ensures your visuals appear crisp and correctly formatted across platforms. Each platform has specific size requirements, so using the right dimensions boosts engagement and maintains brand consistency.

HubSpot contributor Stephanie Trovato has published an article featuring social media image sizes (2025 update) for every platform.

She says, “Between cropped headers, stretched thumbnails, and text that disappeared on mobile, it didn’t take long to realize that each platform plays by its own rules — and they change often. I spent way too much time backtracking, resizing, and apologizing for things that looked off once they went live.

Now, I keep a running list of up-to-date social media image sizes and build templates for the most common social media asset sizes my clients need. It helps me move faster, avoid guesswork, and keep everything looking professional from feed to ad to story.

This guide pulls all of that together—current specs, practical tips, ad dimensions, and tools I use to make the process smoother. I’ve worked with dozens of brands on organic and paid social strategy, and image sizing is one of the first things I coach teams to get right.”
