How Do You Measure Responsiveness of a Website

How Do You Measure Responsiveness of a Website - Banner

A static website design that looks excellent on a computer screen is no longer sufficient because people increasingly access the internet from mobile devices. Not to mention, when creating a design, you must take into account tablets, 2-in-1 computers, and smartphones with various screen sizes. Every web designer should be familiar with the fundamentals of responsive web design or how to make your sites look great. The responsiveness of a website on different devices is a driving indicator for business growth.

For more than 80% of adults, a company's mobile website needs to be just as good as its desktop website. Based on this statistic, we can make an informed assumption about the popularity of responsive web design. The technical obstacles are eliminated by responsive web design solutions, which provide an excellent user experience.

What is Responsive Website Design?

Responsive design allows websites to adapt to various screen sizes while maintaining functionality and the user experience. Text, UI elements, and images scale and resize based on the viewport.

For instance, your content may be divided into different columns on desktop screens, as they are large enough to accommodate that design. However, users will need help to read and interact with your content if you divide it into multiple columns on a mobile device. Responsive design allows you to deliver different layouts of your content and design to other devices based on screen size.

Responsive web design assists you in avoiding the following:

  • incorrect resizing
  • inconvenient scrolling 
  • inappropriate zooming
  • wrong panning

Due to responsive design, developers can create a particular set of HTML, CSS, and JavaScript code for many devices, software platforms, and browsers. Making an existing website responsive can be challenging, but early development investments in responsive web design surpass the difficulty.

Why is Responsiveness of a Website Important?

If you're new to website design or development, you might wonder why responsive design is essential. The solution is simple. It is no longer satisfactory to design for a single device. Mobile accounts for about half of all web traffic globally. Mobile devices (excluding tablet devices) accounted for around 58% of global website traffic in the second quarter of 2022. 

According to these statistics, the use of mobile devices is increasing every day, which implies that more customers will view your website from mobile devices. If your website responds smartly on mobile, users will probably shift their focus to a competitor's website.

When more than half of your potential visitors use a mobile device to surf the internet, you can serve them a desktop-designed for a desktop. However, it would be difficult to read and use, resulting in a poor user experience.

Why is Responsive Website Design Testing Important?

The number of people using their smartphones for social media, shopping, informational purposes, and entertainment is increasing daily. Therefore, your website must be accessible on multiple devices and mobile-friendly.

Avoid issues with your site's responsibility to give your users the most excellent experience possible. Testing responsive designs is the best option. After you have successfully created a responsive website, you must test it to ensure that it can:

  • Consistently display and align the content.
  • The text should be viewable at all scales and viewports.
  • Keep text and images within their respective containers.
  • Images can be shown and resized as needed.
  • Users should be able to scroll vertically or horizontally.
  • Allow users to navigate through links and menus on all devices.
  • Mobile devices scale or resize content based on portrait or landscape orientation.

You can check responsiveness of a website in the following ways:

  • First, use specialized tools to assist you with this.
  • Then, check it with your browser, such as Google Chrome.

We have entered a new era of web design and development. We should instead usher in a new era by developing websites that are future-ready right now. Understanding how to make a website responsive takes little time or effort. It can be less stressful and more effective than learning to create and code correctly for every device available.

Responsive website design is a concept that, when used appropriately, can increase user engagement but only partially address all user, device, and platform issues. We must recognize the importance of responsive web design for business growth and continuously work with new devices, resolutions, and technologies to boost the user experience as technology changes in the years ahead.
