Frequently Asked Questions
What image sizes do social media platforms require?
Each platform has its own recommended dimensions. Instagram posts work best at 1080x1080 (square), 1080x1350 (portrait), or 1080x566 (landscape). Twitter/X posts need 1200x675. Facebook and LinkedIn posts should be 1200x630. TikTok and Instagram Stories/Reels need 1080x1920 (vertical). YouTube thumbnails are 1280x720. Pinterest pins are best at 1000x1500.
Is my image uploaded to a server?
No. This checker runs entirely in your browser using JavaScript. Your image never leaves your device. We just read the pixel dimensions locally and compare them against known platform requirements.
What happens if my image is the wrong size?
The checker will show you exactly how your image differs from each platform's requirements and give you a specific recommendation. You can then resize your image to match. On iPhone, PhotoStrip can batch-resize images to exact dimensions for any platform.
Does the aspect ratio matter more than exact pixels?
Both matter, but aspect ratio is often more important. Most platforms will scale your image up or down, but if the aspect ratio is wrong, your image will get cropped. This tool checks both dimensions and aspect ratio to give you the full picture.
