About Social Media Image Sizes

Each social media platform has specific image dimension requirements for optimal display. Using the wrong size can result in cropped, stretched, or blurry images that hurt your brand presence.

Why Sizes Matter

Platforms optimize images for their layouts. An Instagram Story (1080×1920) looks very different from a LinkedIn post (1200×627). Using correct dimensions ensures your content displays as intended.

Understanding Aspect Ratios

Common ratios include 1:1 (square), 16:9 (widescreen), 9:16 (vertical/stories), and 4:5 (portrait). Our tool handles the math and cropping automatically.

Brand Consistency

When repurposing content across platforms, maintaining visual consistency is key. Generate all sizes from one source to keep your branding uniform.
