Before numbers get mentioned, the term screen resolution should be defined.

Screen resolution is measured in pixels-width × height.

For example:

1920×1080 → 1920 pixels in width, 1080 pixels in height (also referred to as a).

But the trick here is: resolution is never the same as screen size. Two laptops can be running one resolution of 1920×1080 while one has a 13-inch display and the other has a 17-inch display.

The resolution sizes matter more considering web design-they determine how much content fits onscreen and how layouts will adapt across devices.

As technology grows ahead, the variety of screen sizes across devices continues to grow. Desktop monitors, laptop screens, and mobile devices are some of the few areas wherein knowing the most common resolutions will make the medium truly unified in visuals and access.

As far as desktop resolution is concerned, most users probably still go by the tried-and-true 1920×1080 (Full HD) resolution.

With time, there are so many options when it comes to screen size and resolution. A perfect experience should be available to every user, be it a designer working on 4K or a student on a budget laptop.

1920×1080 (Full HD) → It is still considered the most common desktop resolution and enjoys the largest share as far as global screen use is concerned. It is commonly accepted as the standard resolution among desktop and laptop users.
1366×768 → Still the default resolution for budget laptops, more so in the educational field or entry-level jobs.
1536×864 & 1440×900 → These are seen more in mid-range laptops, thus common in professional workplaces.
2560×1440 (QHD) → The “es”-word for designers and creators of content, with gamers competing for its sharper visuals.
3840×2160 (4K UHD) → It is picking its grounds up as the talk among high-end desktop users, especially for design and multimedia.

Pro Tip: Between 1366×768 and 1920×1080, test your sites or apps, as these resolutions are the most commonly used by laptop and desktop users.

The article tends to give more attention to precise desktop size and laptop-screen sizes; in reality, the mobile traffic dominates the globe.

412×915 px → Bigger Android gadgets.

Mobile screen resolutions are getting taller, heading toward 19:9 and 20:9 aspect ratios that make scrolling vertically more natural.

Tablets seem to continue to fill up the gap between mobile and desktop. Here are the tablet display sizes that are more relevant for use:

768×1024 px → Regular iPad in portrait orientation.
1280×800 px → Common on Samsung Galaxy Tab devices.

800×1280 px → An Android tablet.
