Easily Determine Image Aspect Ratios
Use this tool to check the aspect ratio of images for website creation, social media posting, photo trimming, and more. Checking multiple images one by one can be tedious, so we created this tool to solve that problem.
How to Check Aspect Ratio
Step 1 Upload Images
Upload images to check by dragging and dropping them into the designated area, or by selecting them using the "Select Files" button. Supports major image formats such as JPEG, PNG, GIF, SVG, ICO, and WebP. You can add multiple images at once and upload more later.
Step 2 Enter Ideal Aspect Ratio (Optional)
Enter the ideal aspect ratio you want to compare, such as "16:9" or "4:3". If you don't enter a value, you can still see the current aspect ratio of each image. When you enter an ideal ratio, the difference between it and the uploaded images is automatically calculated, and rows with large differences are highlighted, allowing you to quickly identify discrepancies.
Step 3 Check Results & Download
After uploading, a list of each image's "Image Name", "Width (px)", "Height (px)", "Aspect Ratio (e.g., 16:9)", "Aspect Ratio (Decimal)", "Ideal Ratio", "Ideal Ratio (Decimal)", and "Difference" is displayed immediately. In addition, a small thumbnail (preview) of each image is also displayed for visual confirmation. The displayed results can also be downloaded in CSV format (excluding the preview column).
