How to use this tool

  1. Enter original width, original height, linear crop factor.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Cropped width = floor(width/factor), height = floor(height/factor). Megapixels = cropped width×height/10⁶.

A WORKED EXAMPLE

Using original width = 6000 pixels, original height = 4000 pixels, linear crop factor = 1.5, the result is 10.664 MP. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

Centered crop retaining the original aspect ratio, with no resampling. Crop factor is linear, so pixel area falls approximately with its square.

What to keep in mind

Centered crop retaining the original aspect ratio, with no resampling. Crop factor is linear, so pixel area falls approximately with its square. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.

Common questions

How do I use this crop resolution calculator?

Estimate remaining pixel dimensions and megapixels after applying a linear crop factor. Enter original width in pixels, original height in pixels, linear crop factor. The starting example is editable; use values for the same system or project.

Which assumptions affect this result?

Centered crop retaining the original aspect ratio, with no resampling. Crop factor is linear, so pixel area falls approximately with its square.
