Social Media Image Size Guide

About Social Media Image Size Guide

The Social Media Image Size Guide is a comprehensive, always-updated reference for every image and video dimension you need across all major social platforms. Whether you're a social media manager preparing content for multiple channels, a designer creating assets for a campaign, or a small business owner trying to look professional online, this guide ensures your visuals are pixel-perfect on every platform.

How to Use This Guide

Click on any platform tab (Instagram, Facebook, Twitter/X, YouTube, TikTok, LinkedIn, or Pinterest) to see all recommended image sizes for that platform. Each card shows the image type, a visual aspect ratio preview, exact pixel dimensions, and practical tips. Use the search bar to filter across all platforms at once — search for terms like "profile," "story," "thumbnail," or "ad" to quickly find specific dimensions. Click the copy button (⧉) next to any dimension to copy it to your clipboard.

Why Image Sizes Matter for Social Media

Using the correct image dimensions is critical for three reasons: visual quality (incorrectly sized images get stretched, cropped, or compressed), engagement (properly sized content looks professional and gets higher interaction rates), and platform algorithms (social platforms favor content that follows their specifications, potentially boosting your reach). Each platform has its own set of recommended dimensions that are optimized for how content is displayed in feeds, profiles, and stories.

Understanding Aspect Ratios

Aspect ratios describe the proportional relationship between width and height. The most common ratios in social media are: 1:1 (square — universal for profile pictures and many feed posts), 4:5 (portrait — popular for Instagram feed posts because it takes up more screen space), 16:9 (landscape — standard for YouTube videos and X/Twitter posts), 9:16 (full portrait — the standard for Stories, Reels, TikTok, and Shorts), and 1.91:1 (wide landscape — used for link previews and Facebook shared links).

Pro Tips for Image Optimization

Upload at 2x resolution when possible — retina displays show images at double density, so a 400×400 upload for a 200×200 display will look much sharper. Keep safe zones in mind for stories and banners, where UI elements (like the username bar, CTA buttons, or timestamps) cover parts of your image. Use PNG for text-heavy graphics (infographics, quotes, screenshots) and JPEG for photographs to balance quality and file size. Test on mobile first — over 80% of social media usage is on mobile devices.

Frequently Asked Questions

What is the best image size for Instagram posts in 2026?

The recommended image size for Instagram feed posts is 1080 x 1080 pixels for square posts (1:1 ratio), 1080 x 1350 pixels for portrait posts (4:5 ratio, which gets the most screen real estate), and 1080 x 566 pixels for landscape posts (1.91:1 ratio). Instagram supports images up to 2048px wide.

What size should a YouTube thumbnail be?

YouTube thumbnails should be 1280 x 720 pixels with a 16:9 aspect ratio. The minimum width is 640 pixels, and the file size must be under 2MB. Supported formats are JPG, GIF, and PNG. Custom thumbnails are one of the most important factors for click-through rate.

What are the dimensions for TikTok videos?

TikTok videos should be 1080 x 1920 pixels with a 9:16 aspect ratio (full portrait). This is the standard vertical video format. TikTok profile pictures are displayed at 200 x 200 pixels in a circular crop.

Do social media platforms compress uploaded images?

Yes, all major social platforms compress uploaded images to reduce file size and loading time. To minimize quality loss, upload images at the exact recommended dimensions, use PNG format for graphics with text or sharp edges, and JPEG at 80-95% quality for photographs. Uploading at 2x the display size can also help maintain sharpness on retina displays.

What is the difference between a Facebook cover photo and a profile picture size?

A Facebook profile picture is displayed at 176 x 176 pixels on desktop (recommended upload size is 320 x 320 pixels) and is cropped to a circle. The Facebook cover photo is 820 x 312 pixels on desktop and 640 x 360 pixels on mobile. Because cover photos display differently on mobile and desktop, keep important content in the center safe zone.
