SymbolMeaning & Description
RatioWidth proportion : Height proportion
WidthResolution width in pixels
HeightResolution height in pixels
GCDGreatest 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
