Open Graph Image Size Validator
Enter pixel width and height to check a social sharing image against the common Open Graph target.
A QUICK WALKTHROUGH
How to use this tool
- Enter the image width and height in pixels.
- Compare the dimensions and 40:21 aspect ratio with the target.
- Use the result to adjust your social preview image.
Reference target
The reference target is 1200 × 630 pixels, a 40:21 aspect ratio. Other dimensions can have the same ratio without matching the target size.
Dimensions only
This tool validates the numbers you enter. It does not fetch a URL, upload a file, read image metadata, or inspect pixels.
GOOD TO KNOW
Common questions
Does it fetch my image URL?
No. It accepts width and height values only.
Is matching the ratio enough?
No. The result distinguishes exact 1200 × 630 dimensions from a ratio-only match.
