Why Image Size Matters
How to check image size without opening editing software
Sarah, a blogger, wasted hours editing images that were already the right size. Like 43% of creators (Adobe 2023 survey), she didn't realize most devices show dimensions instantly.
- Right-click the image file on your computer
- Select "Properties" (Windows) or "Get Info" (Mac)
- Check the Dimensions or More Info section
Pro Tip: Use IMGO Online Tool for batch checking multiple files.
What size is this image for social media? Platform requirements
