Social Media Image Sizes for Every Platform (2026)

Using the wrong image size on social media costs you reach. Cropped thumbnails, blurry uploads, and black-barred videos all signal low-quality content to the algorithm. Bookmark this guide — we keep it updated.

Why Image Sizes Matter for Reach

Every platform has preferred dimensions. When you upload content that doesn't match those dimensions:

• Images get auto-cropped in unexpected ways
• Videos get letterboxed or pillarboxed
• Thumbnails appear blurry or cut off in the feed
• The algorithm may deprioritize content with poor visual quality signals

Getting your dimensions right takes 30 seconds and meaningfully improves how your content is presented.
