Social Media Image Size Checker
Social media platforms use different image dimensions and aspect ratios for posts, stories, thumbnails, profile images and other content.
This free image size checker lets you quickly inspect an image before publishing it. You can see the image's exact width, height, aspect ratio, file size, format and megapixel count.
How to Check Your Image Size
Checking an image is simple:
- Click the Choose Image button.
- Select an image from your phone or computer.
- You can also drag and drop an image into the upload area.
- The tool automatically reads the image dimensions.
- Compare the image with the listed social media sizes.
Why Image Size Matters
Using an unsuitable image ratio can cause social media platforms to crop, resize or reposition parts of your image. Preparing an image with an appropriate size can help preserve the intended composition.
Supported Platforms
The checker provides common image-size references for several popular platforms, including:
- YouTube
- TikTok
- X / Twitter
Private Browser-Based Checking
The basic checker reads the image directly in your browser. It does not require you to create an account or send the image to an image-processing server.
