About Aspect Ratio
The aspect ratio is the width divided by the height, and a value near 1 is square while larger values are landscape and smaller are portrait. Aspect ratio decides how an image fits prints, social feeds and screens, so cropping to the intended format helps avoid surprises.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
