How to use this calculator
- Enter original megapixels in MP.
- Enter linear crop factor in ×.
- Select Calculate and keep the output unit with the answer.
Before you use the answer
Keep capture settings, physical dimensions and delivery requirements in separate columns of the job notes. A mathematically equivalent setting may change motion blur, depth of field or noise. Check an actual frame before committing an entire session to a numerical estimate.
This describes cropping existing pixels, not optical magnification or resampling.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
