Calculator Input Panel
Use this engineering-focused tool to compare source media, target framing, safe fit, fill behavior, and crop impact.
Formula Used
The calculator also estimates crop-safe dimensions by trimming either width or height until the source matches the selected delivery ratio.
How to Use This Calculator
- Enter the source width and height of your media.
- Select a target preset, or choose the custom option.
- Type custom ratio values when using a custom frame.
- Set the maximum delivery width and height limits.
- Choose a scale percentage for quick resized output.
- Enter PPI if you want diagonal inches.
- Press the calculate button to generate outputs.
- Review fit, fill, crop, and export-ready values.
- Use the CSV or PDF buttons for download.

FAQs
1. What does this calculator measure?
It compares source dimensions, target ratio, delivery size, fit results, fill results, crop-safe framing, scaling outputs, megapixels, and diagonals.
2. What is the difference between fit and fill?
Fit keeps the whole image visible inside the target frame. Fill covers the full frame, but it may crop width or height.
3. Why does the delivery resolution change?
The delivery frame is limited by the maximum width and height you entered. The selected ratio scales inside those limits.
4. When should I use a custom ratio?
Use custom values when your camera, display, engineering panel, or design frame does not match the built-in presets.
5. What does crop loss percentage mean?
It shows how much source image area must be removed to match the chosen target ratio without distortion.
6. Is diagonal inches always accurate?
It is accurate only when the supplied PPI matches the real pixel density of the intended display or imaging surface.
7. Can I use this for video and still images?
Yes. The formulas work for video frames, still photos, displays, engineering panels, mockups, and cropped output planning.
8. Why export CSV or PDF?
CSV is useful for spreadsheets and batch records. PDF is useful for reviews, approvals, and fixed documentation snapshots.
