ratio = original width / original heightnew height = new width / rationew width = new height × ratioWorked example
Worked example using the form's default values.
Only from the values entered or selected in the form and the explicit rules shown with the formulas.
No. Enter prices, rates and device parameters yourself so that the calculation remains reproducible.
Treat it as a documented estimate and check the stated limitations before making a decision.
Yes. Save A/B/C scenarios or add the result to a local project.
Automated tests check the formulas against independently recalculated examples. Calculators covering law, finance, health and construction also passed an editorial merit review with explicitly stated limitations; see the methodology section.
Resize an image by width or height without changing its original aspect ratio. The deterministic model uses only explicit inputs and documented constants.
