Aspect Ratio Formula Explained
The 9:16 ratio is based on a simple mathematical relationship.
1. Width to Height Formula
Height is calculated using:
Height = (Width × 16) ÷ 9
This means the height is 1.77 times the width.
2. Height to Width Formula
Width is calculated using:
Width = (Height × 9) ÷ 16
This means the width is 0.5625 times the height.
Understanding the Math Behind It
The ratio 9:16 can also be written as:
9 ÷ 16 = 0.5625
So:
- Width = Height × 0.5625
- Height = Width × 1.777
These formulas ensure that the proportions always remain consistent regardless of size.
Real-Life Example of 9:16 Conversion
Let’s understand with a practical example:
Example 1: Width to Height
If your width is 1080 pixels:
Height = 1080 × 16 ÷ 9
Height = 1920 pixels
So the resolution becomes 1080 × 1920, which is the standard for vertical videos.
Example 2: Height to Width
If your height is 1920 pixels:
Width = 1920 × 9 ÷ 16
Width = 1080 pixels
Again, the result confirms a perfect vertical video size.
