About Screen Size Calculations
Screen size calculations help you determine the actual width and height of a display based on its diagonal measurement and aspect ratio. This is useful for comparing different screen sizes and understanding how much space a display will occupy.
Screen Size Tips
- Viewing Distance: Larger screens need greater viewing distance for optimal experience
- Resolution: Higher resolutions look better on larger screens
- Space Planning: Consider room dimensions when choosing screen size
- Aspect Ratio: Different ratios are better for different content types
- PPI: Larger screens with same resolution have lower pixel density
- Mounting: Ensure wall/stand can support the screen weight
