Aspect Ratio Reduction Formula
Variable Glossary
| Symbol | Meaning & Description |
|---|---|
| Ratio | Width proportion : Height proportion |
| Width | Resolution width in pixels |
| Height | Resolution height in pixels |
| GCD | Greatest Common Divisor factor |
Step-by-Step Worked Example
1. Mapped Variables
Width (px)
1920
Height (px)
1080
2. Equation Substitution
Equation with standard inputs
Ratio = (1920 ÷ 120) : (1080 ÷ 120)
3. Calculation Steps
Step 1: Compute Greatest Common Divisor (GCD)
GCD(1920, 1080) = 120
Step 2: Reduce width and height dimensions
Reduced Width = 1920 ÷ 120 = 16. Reduced Height = 1080 ÷ 120 = 9.
Step 3: Output simplified ratio format
Aspect Ratio = 16:9
Final Resolved Simplified Aspect Ratio16:9
