The Definitive Guide to Social Media Image Sizes in 2025
Every social media platform has different image dimension requirements, and using the wrong size can mean your photos appear cropped, blurry, or stretched. Understanding the correct dimensions for each platform — and knowing how to resize your images quickly — is an essential skill for anyone creating content online.
This guide covers the exact recommended dimensions for every major social media platform and shows you how to resize any image to the perfect size using Rappider's free online tool.
Why Image Dimensions Matter
When you upload an image that doesn't match a platform's recommended dimensions, several things can go wrong:
- Cropping: Platforms crop images to fit their display format. If your subject is near an edge, it might be cut off entirely.
- Upscaling: If your image is too small, the platform stretches it to fill the required space, resulting in blurry, pixelated output.
- Compression artifacts: Many platforms apply additional compression to oversized images, degrading quality.
- Poor feed appearances: On grid-based platforms like Instagram, inconsistent sizes create a disorganized, unprofessional look.
Instagram Image Sizes
Instagram supports multiple post formats, each with specific requirements:
- Square post: 1080 × 1080 pixels (1:1 ratio) — the classic Instagram format
- Portrait post: 1080 × 1350 pixels (4:5 ratio) — takes up more feed space, gets more engagement
- Landscape post: 1080 × 566 pixels (1.91:1 ratio) — panoramic format
- Stories: 1080 × 1920 pixels (9:16 ratio) — full screen vertical format
- Reels: 1080 × 1920 pixels (9:16 ratio) — same as Stories
- Profile picture: 320 × 320 pixels (displays at 110 × 110)
Tip: The 4:5 portrait format (1080 × 1350) takes up more vertical space in the feed than square posts, meaning your photo gets more screen real estate and typically sees higher engagement rates.
Facebook Image Sizes
- Feed post (shared image): 1200 × 630 pixels recommended
- Cover photo: 820 × 312 pixels (desktop) — displays at 820 × 312 on desktop, 640 × 360 on mobile
- Profile picture: 170 × 170 pixels (desktop display)
- Stories: 1080 × 1920 pixels
- Event cover: 1920 × 1080 pixels
- Group cover: 1640 × 856 pixels
Twitter / X Image Sizes
- In-stream photo: 1600 × 900 pixels (16:9 ratio recommended)
- Profile photo: 400 × 400 pixels
- Header/banner: 1500 × 500 pixels
- Card image: 800 × 418 pixels (1.91:1 ratio)
Note: Twitter crops in-stream photos to approximately 16:9 in the feed preview. The full image is only shown when clicked. Design your photos so the important content is in the center 16:9 safe zone.
LinkedIn Image Sizes

- Article cover image: 1920 × 1080 pixels
YouTube Image Sizes

- Channel art/banner: 2560 × 1440 pixels — safe zone for all devices is 1546 × 423 pixels in the center
- Video thumbnail: 1280 × 720 pixels (16:9) — this is one of the most important images for click-through rates
Pinterest Image Sizes
- Standard pin: 1000 × 1500 pixels (2:3 ratio) — tall, vertical images perform best on Pinterest

Best Practices for Multi-Platform Content
Creating content for multiple platforms simultaneously requires a bit of strategy:
- Shoot at maximum resolution: Always photograph or create at the highest resolution possible. You can always reduce size, but you cannot add pixels back without losing quality.
- Design for the center: Keep important elements (faces, text, logos) in the center of the frame. Most platforms crop from the edges, and the center is almost always safe.
- Create a master image first: Start with a high-resolution master (e.g., 2400 × 2400) and export different sizes from that, rather than repeatedly resizing the same file.
- Use PNG for graphics, JPEG for photos: For images with flat colors, logos, or text, PNG preserves crispness. For photographic images, JPEG at 80–90% quality provides excellent results at smaller file sizes.
