The Ultimate Guide to Social Media Image Sizes (2025)

As you’ve probably realized, social media isn’t one size fits all. What works for one client won’t necessarily work for another. The same thought applies to the size of the graphics you’re posting. Each platform has different size requirements, so let's talk about it! 

Size optimization is important because it can help increase views, engagement, and impressions. Following a size guide also keeps your images from being pixelated or awkwardly stretched when uploading. A good tip to remember for all image sizing is to upload a PNG or JPG to avoid compression or distortion when posted. 

Instagram

Instagram was founded as a visual platform, so having images of the right size is especially important. 

• Profile photo: 320 x 320 px

• Landscape: 1080 x 566 px

• Portrait: 1080 x 1350 px

• Square: 1080 x 1080

• Stories and Reels: 1080 x 1920

• Photo thumbnail size: 

  • Display size: 161 x 161 px

  • Recommended upload size: 1080 px wide 

Always aim for a width of 1080 px to prevent auto-resizing. As long as the aspect ratio falls between 1.91:1 and 4:5, your images will look sharp and professional. Instagram stores thumbnails up to 1080 x 1080 px, so bigger is better.

Pro Tip: We highly recommend posting portrait (1080 x 1350 px) images whenever possible. Portrait posts take up more real estate on the grid and in your followers' feeds, making your content stand out and more likely to grab attention

Facebook

Facebook is the world’s largest social media platform with about 2.96 billion active monthly users.

• Profile photo: 170 x 170 px

• Landscape: 1200 x 630 px

• Portrait: 630 x 1200 px

• Square: 1200 x 1200 px

• Stories and Reels: 1080 x 1920 px

• Cover photo: 851 x 315 px

Facebook updates its design and image dimensions constantly. The best strategy to future-proof your brand’s content is to always upload the highest-quality image you can. Stick to Facebook’s recommended file formats for the best results.

X (Twitter)

X is a conversation-based platform. If your brand is posting here you’ll still want to incorporate images that will start a conversation with your followers. 

• Profile photo: 400 x 400 px

• Landscape: 1600 x 900 px

• Portrait: 1080 x 1350 px

• Square: 1080 x 1080 px

• Cover photo: 1500 x 500 px

TikTok

• Profile photo: 200 x 200 px

• Landscape: 1920 x 1080 px

• Portrait: 1080 x 1920 px

• Square: 1080 x 1080 px

• Stories: 1080 x 1920 px

• Caousel: 1080 x 1920 px

The ideal aspect ratio for vertical TikTok videos is 9:16. You can post vertical videos with other dimensions, but the platform will add black bars to the top and bottom of the videos so they are full-screen.

The ideal aspect ratio for horizontal TikTok videos is 16:9. When you upload a video with these dimensions, a Full-Screen button will appear that allows users to view the full video by flipping their screens sideways.

LinkedIn

Pairing your LinkedIn updates with images has consistently been shown to increase comments and sharing.

• Profile photo: 400 x 400 px

• Landscape: 1200 x 627 px

• Portrait: 627 x 1200 px

• Square: 1080 x 1080 px

• Cover photo: 1128 x 191 px

LinkedIn has also recently started pushing video content. There isn’t much data right now on the optimal size, but we’ve seen good results when using the 1080 x 1080 px sizing for graphic-style videos.

Your social media strategy hinges on not just what you post but how you post it. Properly sized images show your audience (and the algorithms!) that you’re serious about your content. Ready to level up? Let’s chat about how our custom social media management packages can help your brand buzz.
