Best Image Dimensions to Make Your Posts Pop
Ideal Image Sizes & Formats for Your Social Media Posts
When you're posting content on social media, the images you use can seriously impact your engagement. Crisp visuals stop the scroll. Blurry or awkwardly cropped images? Not so much. Here’s a straightforward guide to the best image sizes and formats across major platforms—optimized for SocialPost users.
General Best Practices
- Use JPG for photos, PNG for graphics or text-heavy images.
- Stick to high resolution (at least 1080px wide).
- Vertical formats usually perform better on mobile-first platforms.
- Avoid large file sizes (over 20MB) to ensure quick loading.
- Square post: 1080 x 1080 px
- Portrait post: 1080 x 1350 px
- Landscape post: 1080 x 566 px
- Stories & Reels: 1080 x 1920 px
Portrait posts (4:5 ratio) tend to take up more screen space and draw more attention in the feed.
X (formerly Twitter)
- Single image post: 1600 x 900 px (16:9 ratio)
