The monitors you attach to your computer and laptop screens have display resolutions in pixels. Each pixel represents a dot on the screen, and the horizontal and vertical pixels make up the screen resolutions. This online tool uses javascript to display your monitor's screen size and browser window size in pixels.

Screen Size 1280 px X 720 px
Window Size 1280 px X 720 px

This tool works on any device that supports javascript on their browser. The monitors and laptop screens do not always use maximum resolutions, so you can increase the resolution if your display device supports higher resolutions. On Windows 10, you can change screen resolution by following Change desktop icon size or screen resolution page on Microsoft. On Mac, you can change screen resolution by following Apple page.


Display Resolutions

The display industry has advanced dramatically over the years, and monitors with 2K, 4K, and 8K resolutions are not uncommon these days. In the late 90s and early 2000s, the 1024 x 768 was the most common resolution used. Today, the most commonly used display resolution is 1920 x 1080. The ratio between the horizontal and vertical has changed from 4:3 to 16:9, and the 16:9 aspect ratio is the new normal used on most monitors today.

The following display standards have evolved into the current resolutions.

Standard Name Width Height
NTSC EDTV 720 480
PAL EDTV 720 576
VGA 640 480
SVGA 800 600
XGA 1024 768
HD 720p 1280 720
WXGA 1280 800
SXGA 1280 960,1024
WSXGA 1680 1050
FHD 1080p 1920 1080
WUXGA 1920 1200
DCI 2K 2K 2048 1080
QHD 1440p 2560 1440
WQHD 3440 1440
UHD 4K 3840 2160
UHD 5K 5120 2880
UHD 8K 7680 4320

There are so many variations of horizontal and vertical displays, and the name and standard overlaps with minor pixel differences. We generally use 2K with a monitor having roughly 2,000 horizontal pixels, 3K with 3,000 pixels, 5K with 5,000 pixels and so on.
