Frequently Asked Questions
What is the best aspect ratio for Instagram posts?
The optimal Instagram aspect ratio is 4:5 (portrait) at 1080×1350 pixels, which achieves 98% engagement rates. This format takes up more screen space in feeds and performs significantly better than square 1:1 posts. For Instagram Stories and Reels, use 9:16 vertical format at 1080×1920 pixels.
How do I calculate the missing dimension for social media images?
Enter either width or height in our calculator, and it automatically computes the missing dimension based on the selected platform's optimal aspect ratio. For example, if you enter 1080px width for Instagram 4:5 format, it calculates 1350px height to maintain perfect proportions.
What are the minimum image sizes for each social media platform?
Minimum sizes vary by platform: Instagram (320×320), Facebook (600×315), Twitter (600×335), LinkedIn (600×314), TikTok (540×960), YouTube (640×360). However, using recommended optimal sizes ensures better quality and engagement. Our calculator shows both minimum and optimal dimensions.
Why do different social media platforms require different image ratios?
Each platform optimizes for different user experiences and device usage patterns. Instagram prioritizes mobile-first vertical content, LinkedIn focuses on professional horizontal layouts, and TikTok is designed for full-screen vertical videos. Using platform-specific ratios ensures your content displays properly without cropping or letterboxing.
How often do social media image requirements change?
Social media platforms typically update image specifications 1-2 times per year, usually during major platform redesigns or feature launches. Our calculator is updated regularly to reflect the latest requirements and industry best practices. We recommend bookmarking this tool and checking for updates quarterly to ensure compliance.
Can I use the same image size for multiple platforms?
While some ratios like 1.91:1 work for both Facebook and LinkedIn posts, each platform performs best with its optimized dimensions. For maximum engagement and professional appearance, create platform-specific versions. Our calculator helps you quickly determine the right size for each platform from a single source image.
What file formats work best for social media images?
JPG is ideal for photos with many colors, PNG for graphics with transparency or text, and WebP for modern browsers seeking smaller file sizes. Most platforms accept JPG, PNG, and GIF formats. Keep file sizes under 30MB for optimal upload speeds and maintain image quality above 72 DPI for sharp display on all devices.
