This comprehensive guide, updated for 2025, addresses the critical importance of correct **social media image sizing for every platform**. Author David Castle, drawing on extensive experience with organic and paid social strategy, explains why a “one-size-fits-all” approach doesn’t work, leading to issues like cropped headers, stretched thumbnails, and disappearing text.

The guide details **current image specs for platforms** including Facebook, Instagram, Twitter (X), TikTok, LinkedIn, Pinterest, YouTube, Threads, Snapchat, Google Business Profile, Bluesky, and Tumblr. It also provides **specific dimensions for paid social ads** on Meta (Facebook and Instagram), Twitter, LinkedIn, TikTok, Pinterest, and YouTube, emphasizing that ad specs can differ from organic posts and require double-checking to avoid rejections or underperformance.

You’ll discover recommended tools and templates like **Canva, Pixlr, Adobe Express, and HubSpot’s free templates** to simplify design and reformatting. Additionally, the guide offers practical tips for **better image optimization**, focusing on mobile-first design, understanding safe zones, using appropriate file formats (JPG for photos, PNG for logos), and maintaining brand consistency. The author emphasizes that getting image sizing right is a “small step that makes a big difference,” leading to sharper visuals, stronger engagement, and fewer issues with campaigns.
