Social Media Image Sizes Guide for 2026
Using the wrong image dimensions is one of the most common mistakes on social media. An image that looks perfect on Instagram gets cropped awkwardly on Twitter, and a YouTube thumbnail designed at the wrong size appears blurry on every device. Each platform has specific dimension requirements, and getting them right means your content looks professional and gets more engagement. Here is the complete reference.
Instagram: Square posts 1080x1080, portrait 1080x1350 (best for feed engagement), landscape 1080x566, Stories/Reels 1080x1920. TikTok: Video/cover 1080x1920 (9:16). YouTube: Thumbnails 1280x720, channel banner 2560x1440. Twitter/X: Post images 1200x675, header 1500x500, profile 400x400. LinkedIn: Post images 1200x627, company banner 1128x191, profile 400x400. Facebook: Post images 1200x630, cover photo 820x312, profile 170x170. Pinterest: Standard pin 1000x1500 (2:3 ratio). These are the recommended upload sizes - platforms may display them differently in feeds.
JPEG is best for photographs and complex images with many colors - it offers good quality at smaller file sizes. PNG is ideal for graphics, logos, screenshots, and images with text because it preserves sharp edges and supports transparency. WebP offers better compression than both JPEG and PNG while maintaining quality, and most platforms now support it. For social media, JPEG at 85-90% quality strikes the best balance between file size and visual quality. Avoid uploading images over 5MB as platforms will compress them aggressively, which can introduce artifacts. If you need transparency (like a logo overlay), PNG is your only option among common formats.
Always start with the highest resolution source image you have. Resizing down preserves quality, but upscaling creates blur and pixelation. Avoid screenshotting images from other platforms - each save-and-reupload cycle degrades quality. Use the platform's recommended dimensions exactly rather than relying on auto-cropping, which often cuts off important parts of your image. For text on images, use a minimum font size of 24px to stay readable on mobile screens. Test your images on both mobile and desktop before posting, as most social media consumption happens on phones where small details get lost. Keep important elements centered since different platforms crop edges differently.
