Aspect ratio crop preview
Preview how much of a photograph a different aspect ratio retains. The centered crop is a geometric starting point; move the crop in an image editor to protect the subject.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
This is an estimate from your inputs, not a guarantee. Check actual capacity, conditions and measurements before making a decision.

How it works
The largest centered rectangle matching the target ratio is retained. Retained area = crop area / original area.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Crop width: 1687.5 pixels
- Crop height: 3000 pixels
- Retained area: 42.1875 %
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
