Screen resolution tester

Detect screen resolution online

I think most of us have been in a situation when, for some reason, we wanted to find out screen resolution. Chances are good that you are in the same situation right now.
There are many different ways to check the screen resolution, but the easiest and the fastest one is to use this online application. This website can determine the resolution of your computer monitor, the resolution of Android smartphone or tablet, iPad, iPhone, or any other mobile device.
Resolution is the number of pixels per unit distance. If your screen resolution is 1024 * 768, this means that the width of your screen is 1024 pixels and the height is768 pixels.
On this page you can find your display resolution, in pixels. It is a very easy and quick online tool. Above you can see your current resolution in pixels, which is defined automatically. So, the next time when you want to check screen resolution of a new device, you just need to go online, open this website and instantly check out the results.
Usually we want to learn about the screen resolution when we change operating system settings, check the system requirements for the new software, or simply out of curiosity. Previously, to solve this problem you would have to download special software, and now the screen resolution can be determined online right here. The method is very simple: just look at the result written in large numbers at the top.

How to perform screen resolution testing

Screen resolution testing of a website requires monitoring website appearance on multiple real devices (mobile and desktop). However, it is not feasible for all individual QAs or teams to set up an extensive device lab just to perform screen resolution testing. 

 An easy way to address this challenge is to use a cloud-based testing tool like BrowserStack’s Responsive Checker. Simply enter the URL of their website under test into the address bar and click on Check. The tool will instantly load the website across multiple real and latest devices(iPhone X, Galaxy Note 10, iPad pro, Windows, Mac OSX) with varied screen resolutions – 375×812, 412×869, 1280×1024, and more

 For comprehensive screen resolution testing, use BrowserStack Live. Its real device cloud provides teams with 2000+ real devices & browsers. Simply sign up for a free trial or opt for a suitable plan and start with screen resolution testing on desired device-browser combinations. No complex setup involved. Testers can also interact with web elements and perform scroll and pinch or zoom operations to mimic end-user activity in the real world. 

Standart screen resolution

There’s no one best screen size to design for. Websites should transform responsively and fast at all screen resolutions on different browsers and platforms. Accessible. Mobile-friendly. Design for your audience, first. Design from 360×640 through 1920×1080.

  • Design for desktop displays from 1024×768 through 1920×1080
  • Design for mobile displays from 360×640 through 414×896
  • Design for tablet displays from 601×962 through 1280×800
  • Check Google Analytics and optimise for your target audience’s most common resolution sizes
  • Do not design for one monitor size or screen resolution. Screen sizes and browser window state vary among visitors.
  • Design should be responsive and fast. Use a liquid or responsive layout that transforms to the current user’s window size.
  • Monitor Google Search Console mobile-friendly and usability alerts
It should still look good and work well at all sizes, which is why I *used to* recommend a highly accessible liquid layout using percentage widths to control layout. Now the recommendation is a responsive website template.
The three main criteria for optimising a page layout for a certain screen size are:
  • Web Page Initial visibility: Is all key information visible above the fold so users can see it without scrolling? This is a tradeoff between how many items are shown vs. how much detail is displayed for each item.
  • Web Page Readability: How easy is it to read the text in various columns, given their allocated width?
  • Web Page Aesthetics: How good does your page look when the elements are at the proper size and location for this screen size? Do all the elements line up correctly — that is, are captions immediately next to the photos, etc.?

The benefit of Using a responsive design Website.

  • Static content nothing to change for all device
  • Images will be optimized and smaller
  • Navigation optimized by devices
  • Great functional on any mobile devices 
  • The smaller image will load quickly on low connections
  • Google acceptable mobile friendly

Steps include creating a page responsive test 

  • Make information better view to easy to view
  • Add proper Meta Viewport Tag
  • Allow autocorrect forms
  • Button size enough for mobile devices 
  • Use better and understandable font size
  • Optimized images and css files
  • Proper Mobile testing
  • Allow easy view desktop as well as mobile
  • Use a better CSS framework like bootstrap, grids, and others.
  • Ignore to use flash type media in web pages
