How to Use This Calculator

Enter the Source Width and Source Height in pixels from the original image file.
Enter the Target Ratio Width and Height (e.g., 16 and 9 for a 16:9 crop).
Review the Crop Width and Crop Height in pixels for the center-cropped output.
Check Percentage Retained and Pixels Removed to understand how much of the image is lost.
Use X Offset and Y Offset to position the crop precisely within your image editing application.

How the result changes with Source Width

Source Width: Width of the original image in pixels.
Source Height: Height of the original image in pixels.
Target Ratio Width: Width component of the target aspect ratio (e.g., 16 for 16:9).
Target Ratio Height: Height component of the target aspect ratio (e.g., 9 for 16:9).
