Compare TVs, monitors, laptops and phones by real width, height and area, drawn to scale, with pixel density and viewing distance
How to use
Two TVs are already compared. Change the diagonal, shape or resolution of either one.
Add up to four screens from the list of TVs, monitors, laptops, tablets and phones.
Switch between Overlay, Centred and Side by side to see the difference, all drawn to the same scale.
Read the table for real width, height, area, pixel density and a comfortable viewing distance, then share the link.
Why use this tool
Real sizes, not just the diagonal: Two screens with the same diagonal can be very different sizes. See the true width, height and area of each, and how much bigger one is than the other.
Drawn to scale: Screens are drawn on top of each other or side by side at one scale, so a 34 inch ultrawide and a 27 inch monitor can be compared at a glance.
Pixel density and sharpness: Set a resolution to see pixels per inch and the distance beyond which individual pixels disappear.
Viewing distance: A recommended seating distance for every screen, from a cinema-like 40 degree view to a relaxed 30 degrees.
Inches or centimetres: Enter and read everything in either unit, and share the exact comparison with a link.
Frequently asked questions
How much bigger is a 65 inch TV than a 55 inch TV?
A 65 inch 16:9 TV has about 40% more screen area than a 55 inch one. It is roughly 8.7 inches wider and 4.9 inches taller, even though the diagonal is only 10 inches longer.
Is a 34 inch ultrawide bigger than a 27 inch monitor?
It is much wider but actually shorter. A 34 inch 21:9 ultrawide is about 31.4 inches wide and 13.1 inches tall, while a 27 inch 16:9 monitor is 23.5 inches wide and 13.2 inches tall.
How far should I sit from my TV?
For a cinema feel, THX suggests a distance of roughly 1.2 times the diagonal, where the screen fills about 40 degrees of your view. For relaxed everyday viewing, about 1.6 times the diagonal. The table shows both for each screen.
What does pixel density mean?
Pixels per inch, or PPI, is how tightly pixels are packed. Higher PPI looks sharper up close. Beyond the distance shown in the table, a person with normal vision cannot make out individual pixels at all.
Why are 21:9 ultrawides listed twice?
Ultrawide monitors are sold as 21:9, but the common 2560 x 1080 panels are really 64:27 and 3440 x 1440 panels are 43:18. Picking the exact shape gives exact dimensions.
