Screen Size Comparison
Type two screen sizes and their shapes to see the width, height and picture area of each and how much bigger one is than the other. It opens on a 55-inch against a 65-inch TV, and it works the same for monitors, laptops and phones, in inches or centimetres.
Compare two screen sizes
A screen is sold by its diagonal, so two sizes are hard to picture side by side. Give each one its diagonal and its shape, and the width, height and picture area come back, with how much bigger one is than the other. Both diagonals are read in the unit chosen, so switching it reinterprets the numbers rather than converting them.
- The second screen has 39.7% more area than the first.
- It is 8.7 in wider and 4.9 in taller.
- First: 55.0 in 16:9 is 47.9 × 27.0 in, 1293 square inches of picture
- Second: 65.0 in 16:9 is 56.7 × 31.9 in, 1805 square inches of picture
- Diagonals: 55.0 in (139.7 cm) and 65.0 in (165.1 cm)
Your own screen
Nothing here is sent anywhere: the page asks your own browser what it knows and prints the answer. The figures refresh on their own when the window changes size or the device turns, so you can drag the window and watch the viewport follow.
Measure a screen by hand
Run a tape measure across the lit picture only, not the frame around it: the width along the bottom edge and the height up one side. Type both here and the diagonal comes back, which is the number a TV, monitor, laptop, tablet or phone is sold by.
- Enter a width and a height to see the diagonal.
Common resolutions
Names and examples for familiar resolutions, with their exact aspect ratios. Phone and tablet rows use CSS pixels; display rows use panel pixels. Browser zoom and display scaling affect how the reported readings relate to these examples. Your own screen is marked when its reported resolution matches a named row.

Common questions
- How much bigger is a 65-inch TV than a 55-inch?
- About 39.7% more picture. At 16:9 a 55-inch TV is 47.9 by 27.0 inches and a 65-inch is 56.7 by 31.9, so the bigger set is 8.7 inches wider and 4.9 inches taller. Area grows with the square of the diagonal, which is why ten inches more diagonal adds so much.
- How do I work out a TV's width and height from its size?
- Divide the diagonal by the square root of the two ratio terms squared and added, then multiply by each term. For 16:9 that root is about 18.36, so the width is the diagonal times 0.872 and the height is the diagonal times 0.490: a 55-inch TV is 47.9 by 27.0 inches. Pick 16:9 above and type the size to get the same figures without the arithmetic.
- Is a 34-inch ultrawide bigger than a 27-inch monitor?
- Wider, not taller. A 34-inch ultrawide at 3440 × 1440 is 31.4 by 13.1 inches, and a 27-inch 16:9 monitor is 23.5 by 13.2, so the ultrawide adds 7.8 inches of width and 32.2% more area while standing 0.1 inches shorter. Set the first screen to 27 at 16:9 and the second to 34 at 21:9 to see it.
- Why does 21:9 use 3440 × 1440?
- Because no 21:9 monitor is exactly 21:9. The common 34-inch ultrawide is 3440 × 1440, which is 43:18, so that shape gives its real width and height. A 2560 × 1080 ultrawide is a touch narrower at 64:27.
- Does it compare laptop and phone screens too?
- Yes. Any two diagonals compare, so a 13.3-inch 16:9 laptop against a 13.5-inch 3:2 one shows the 3:2 screen with 11.3% more area, being narrower and taller. Phones use the 19.5:9 shape.
Exact for what the browser reports: the screen in CSS pixels, the device pixel ratio and the viewport. The physical size in inches and the true DPI are not reported by any browser, so they are not claimed.
