16:9 Ratio Formula Explained
The calculator uses a simple proportional formula based on the 16:9 ratio.
Basic Ratio Formula:
HeightWidth=916
From this, we derive both calculations:
1. To Find Width:
Width=9Height×16
2. To Find Height:
Height=16Width×9
These formulas ensure that the output always maintains the correct widescreen proportion.
Real-Life Example
Example 1: Find Width
If height = 720 px
Width = (720 × 16) / 9
Width = 1280 px
✔ Final Resolution: 1280 × 720 (HD)
Example 2: Find Height
If width = 1920 px
Height = (1920 × 9) / 16
Height = 1080 px
✔ Final Resolution: 1920 × 1080 (Full HD)
