Social Media Image Size Guide

About Social Media Image Size Guide

Using the wrong image size leads to blurry pictures or awkward cropping. This guide lists commonly used image sizes and aspect ratios for Instagram, Facebook, X, LinkedIn, YouTube, Pinterest and TikTok. Designers and social media managers can use it as a quick reference when creating posts, covers and thumbnails. Platforms update their layouts from time to time, so treat the sizes as reliable starting points.

Example

Example: for an Instagram portrait post choose 1080 by 1350 pixels (4:5), and for a YouTube thumbnail use 1280 by 720 pixels (16:9).

Tips for better results

• Keep important text and faces away from the edges, where cropping can occur.
• Export at the recommended size instead of letting the platform shrink a large file.
• Create a template for each size so your posts stay consistent.

When to use Social Media Image Size Guide

Use this when you are about to design a graphic and need the right dimensions before you open your editor. It helps social media managers, small business owners, bloggers and students making posts, covers, thumbnails and banners for several platforms. Look up the platform and format, then build your design at that size or ratio. Since platforms redesign their layouts from time to time, confirm the numbers against the platform's help pages before an important launch or campaign.

Real-world uses

• A designer preparing a campaign needs one design resized for a feed post, a story and a channel banner on different platforms.
• A blogger creating a Pinterest pin wants to know the vertical ratio so her image is not cropped in the feed.
• A nonprofit volunteer updating a Facebook cover photo wants to keep key text inside the visible area on mobile and desktop.
• A YouTuber designing a thumbnail checks the recommended dimensions so the image looks sharp and is not stretched.

Common mistakes to avoid

• Designing at the exact size without a safe margin. Keep logos and text away from the edges so they survive cropping on different devices.
• Mixing up ratio and pixel size. Two images can share a ratio and still differ in sharpness, so export at the recommended pixel dimensions.
• Reusing one image for every platform. Resize or recompose it for each format instead of hoping an automatic crop will keep the focus.

Frequently asked questions

What if a platform changes its sizes?

Use the guide as a starting point and check the platform's official help center for current specs. When in doubt, keep the main subject centered so small changes cause fewer problems.
