Free Online Social Media Image Size Guide
Current image dimensions for every major social platform.
About the Social Media Image Size Guide
Social platforms rarely show an image at the size you upload. They crop, resize, and recompress it for each surface: the feed, the profile grid, stories, search results, and ads. A file that looks perfect on a desktop timeline can lose its headline on a phone or in a square thumbnail. This reference collects the recommended upload dimensions for the major placements on Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, and Snapchat, together with the intended aspect ratio and practical notes about safe areas.
Use the table as a starting point, not as a promise about display size. Design at the recommended dimensions,
keep the aspect ratio intact, and place the most important content near the center. For stories and vertical
video, leave the top and bottom clear because interface controls cover those areas. For profile photos,
upload a square image and expect a circular crop. For link previews, use a 1.91:1 image and set a proper
og:image so the platform has a clear image to fetch.
How to read the table
- Size: the recommended upload dimensions in pixels. Larger files are often downscaled.
- Aspect: the width-to-height ratio. Keeping it avoids unexpected cropping.
- Notes: safe areas, minimum sizes, crops, file formats, and placement-specific behavior.
- Profile photos: square uploads are displayed as circles on most platforms.
- Stories and reels: 9:16 vertical is the standard full-screen format.
Why guides disagree
Platforms change specifications without a large announcement, and different surfaces use different crops. A recommendation may refer to the minimum upload size, the ideal source size, or the final display size. Device pixel ratio adds another layer: a 1080-pixel image may be displayed in a smaller CSS box but still look sharp on a high-density screen. The notes in this table call out the most common source of confusion, and the search filter lets you jump straight to a placement.
Frequently asked questions
Should I upload a larger image than the recommended size?
Uploading slightly larger can help on high-density screens, but platforms recompress and resize files. Going far beyond the recommendation increases upload time and file size without a visible benefit. Keep important content centered and use a high-quality source image.
What is a safe area?
A safe area is the part of a vertical or cover image that remains visible after the platform adds interface controls or crops the sides. Text and logos outside the safe area may be hidden on some devices.
Are these sizes up to date?
This guide was reviewed in November 2026. Platforms can change their recommendations at any time. For a paid campaign or a critical launch, confirm the current specification in the platform's official help center.
Recommended upload sizes. Displayed sizes can differ by device and layout.
Sizes are recommended upload dimensions, not guaranteed display dimensions. Platforms crop and rescale images differently across devices, so keep important text away from edges and check the current help center before a major campaign.
