Why Image Dimensions Matter
Using the correct image dimensions for each social media platform ensures your content looks professional and displays properly across all devices. Incorrectly sized images can appear cropped, pixelated, or stretched, which can negatively impact engagement and brand perception.
Each platform has specific requirements for different types of content - from profile pictures to cover photos, posts, stories, and ads. Using our guide ensures you always upload images with the optimal dimensions.
Best Practices for Social Media Images
- 01Use High Resolution: Always upload the highest quality images possible within file size limits
- 02Maintain Aspect Ratios: Keep consistent aspect ratios for a cohesive feed aesthetic
- 03Optimize File Size: Compress images without losing quality to ensure fast loading
- 04Consider Mobile: Most users view social media on mobile devices - design accordingly
- 05Test Before Posting: Preview how images will look on different devices
- 06Include Text Carefully: Ensure text on images is readable at smaller sizes

FAQ
Frequently asked questions
What size is an Instagram post?
1080x1080 pixels for a square post, 1080x1350 for portrait, and 1080x566 for landscape. Portrait at 4:5 takes up the most feed space, so it is usually the best choice.
What size is an Instagram story?
1080x1920 pixels, a 9:16 vertical ratio. Reels use the same dimensions.
What size is a YouTube thumbnail?
1280x720 pixels at 16:9, with a minimum of 640x360. Keep important detail away from the bottom right corner, where the duration badge sits.
What size is a Facebook cover photo?
820x312 pixels on desktop and 640x360 on mobile. Facebook crops the edges differently on each, so keep text and logos centred.
What size is a LinkedIn banner?
1584x396 pixels for a personal profile and 1128x191 for a company page. They are different ratios, so the same file will not work for both.
What size is an X (Twitter) header?
1500x500 pixels at 3:1. The profile picture overlaps the lower left, so keep that corner clear.
What image format should I use for social media?
JPEG for photographs, PNG when you need transparency or crisp text, and WebP where the platform accepts it for the smallest file at the same quality.
