Social Media Image Size Guide

About This Tool

Social media platforms have specific recommended image dimensions for every content type. Using the wrong size results in cropping, pixelation, or awkward framing that makes your content look unprofessional. This reference guide provides the exact pixel dimensions, aspect ratios, and format types for every major platform, updated for 2026.

Why Image Dimensions Matter

Each platform displays images differently across mobile, desktop, and tablet devices. An image that looks perfect on desktop might get awkwardly cropped on mobile. Using the platform-recommended dimensions ensures your content displays correctly everywhere. This is especially critical for profile pictures, cover photos, and thumbnails where first impressions determine whether someone follows or clicks.

Resolution and File Size Tips

While these dimensions show the minimum recommended sizes, designing at 2x resolution (double the pixel dimensions) ensures crisp display on retina screens. Most platforms accept JPEG and PNG formats. Use JPEG for photographs (smaller file size) and PNG for graphics with text, logos, or transparent backgrounds. Keep file sizes under 5MB for fast loading, though most platforms will compress your images regardless.

Safe Zones for Mobile Viewing

Many platforms overlay UI elements (like usernames, buttons, or captions) on top of your images, especially in Stories and Reels. Keep important text and key visual elements in the center 80% of the image to avoid being covered by platform UI. For YouTube thumbnails, avoid placing text in the bottom-right corner where the video duration badge appears.
