Calculated Dimensions
Aspect ratio: 16:9 (1.7778)
Known dimension: width = 1920 pixels
Formula: Height = Width ÷ Ratio = 1920 ÷ 1.7778 = 1080
Visual Representation
Example Calculation
Full HD Screen Example
Screen: 1920 × 1080 pixels (Full HD)
Want to find: Aspect ratio
Calculation
Step 1: Divide width by height = 1920 ÷ 1080 = 1.778
Step 2: Find GCD of 1920 and 1080 = 120
Step 3: Simplify: 1920÷120 : 1080÷120 = 16:9
Result: 16:9 aspect ratio (Widescreen)

Why is it Important?
- •Determines display proportions and viewing experience
- •Essential for content creation and media design
- •Helps choose the right display for specific applications
- •Prevents image distortion when scaling content
Calculation Formula
Screen Ratio = Width ÷ Height
