When to use?
Use it when comparing monitors, TVs, tablets, or phone screens before purchasing or designing layouts.
How to use
- Enter diagonal size and aspect ratio for each screen.
- Compare width, height, and area.
- Review percentage differences.
Input Explanation
Enter diagonal inches and aspect ratio such as 16:9, 4:3, or a custom ratio.
Calculation Basis
It derives width and height from the diagonal and aspect ratio using the Pythagorean relationship.
Usage Examples
- Monitor comparison - Compare actual screen area beyond diagonal size.
- TV purchase planning - Check how much larger a TV will feel.
- Design preview - Understand relative viewport proportions.
Examples
- 27-inch 16:9 vs 32-inch 16:9 → area comparison
- 13-inch laptop vs 11-inch tablet → width/height comparison
Cautions
- This is an estimate for everyday planning. Actual results can vary by environment, product specifications, personal condition, and local rules.
Guides
Diagonal vs. actual area
The same diagonal can have different width, height, and area depending on aspect ratio.
Useful comparisons
Compare monitor, TV, tablet, or phone sizes by physical area rather than diagonal size alone.
FAQ
Why is diagonal size not enough?
Aspect ratio changes width, height, and area even at the same diagonal.
Does bezel size count?
No, it compares active screen area only.
Can I use custom ratios?
Yes, enter custom width:height ratios where supported.
