Technical Guide

Social media platforms frequently update their image specifications, but the core requirements remain relatively stable. Key concepts: Profile photos are typically square (1:1) and displayed as circles on most platforms. Cover/banner images are wide format and responsive — different portions may be cropped on mobile vs. desktop. Feed posts vary by platform: Instagram favors 1:1 or 4:5, Twitter uses 16:9, LinkedIn uses 1.91:1. Stories and Reels across platforms standardize on 9:16 (1080×1920). For best quality, always upload at the recommended resolution or higher — platforms will compress images but starting with high resolution ensures the best result. Save images as PNG for graphics/text-heavy images and JPEG for photographs. Consider file size limits: most platforms accept up to 5-20MB per image.
