How Our Screen Size Comparison Works
Understanding the science behind accurate display size calculations
Our Calculation Methodology
Easy Compare uses precise mathematical calculations to provide accurate visual representations of screen size differences. Here's how we ensure accuracy:
1. Diagonal-to-Dimension Conversion
We use the Pythagorean theorem combined with aspect ratio data to calculate exact width and height from diagonal measurements. For a screen with diagonal 'd' and aspect ratio 'a:b':
- Width = d × a / √(a² + b²)
- Height = d × b / √(a² + b²)
2. Aspect Ratio Precision
Different aspect ratios significantly affect display dimensions:
- 16:9 - Standard for most TVs and monitors
- 21:9 - Ultrawide monitors for productivity and gaming
- 32:9 - Super ultrawide displays
- 4:3 - Older displays and some professional monitors
- 1:1 - Square displays
3. Visual Scale Accuracy
Our visualization engine automatically scales comparisons to fit your screen while maintaining proportional accuracy. The relative size differences you see are mathematically precise representations of real-world dimensions.
Why This Matters for Your Purchase Decision
Screen Area vs Diagonal
A 32-inch monitor has approximately 40% more screen area than a 27-inch monitor, despite only a 5-inch diagonal difference. Our tool helps you visualize this crucial distinction.
Viewing Distance Impact
The optimal viewing distance varies significantly between screen sizes. Our comparisons help you understand how size changes affect your viewing experience.
Accuracy Guarantee
All calculations are based on industry-standard display measurement practices and verified against manufacturer specifications. Our tool provides the same precision used by display engineers and product designers.
