A Complete Guide To Mobile First Design

What is Mobile First Design?

Mobile-first design is a website development philosophy that prioritizes addressing the needs of mobile users by creating a layout tailored for smaller screens from the beginning. This approach aims to enhance the mobile user experience by considering device constraints. In contrast to graceful degradation, which starts design with larger screens and adjusts downward, mobile-first design embraces progressive enhancement. It recognizes that device dimensions limit user access to content, focusing on optimizing crucial features for mobile users and streamlining the overall user experience.

“Progressive Advancement” and “Graceful Degradation” are design concepts predating responsive web design. In Progressive Advancement, a basic version is designed for lower-end browsers, like mobile phones, with subsequent creation of an advanced version for tablets or PCs. This involves adding interactions and complex features for an improved user experience. On the other hand, “Graceful Degradation” begins design from an advanced end, like desktop, and adapts the product for mobile compatibility by removing some functions or content.

Myntra was the first company to adopt app-only strategy which reportedly backfired. Closing its desktop site in favor of a mobile app, Myntra claimed 95% of its internet traffic and 70% of sales were mobile-driven. However, approximately six months later, facing a decline in traffic and sales, Myntra reintroduced their website on mobile browser and desktop. Proving that companies should focus on mobile first design websites that are compatible with desktop and not just the apps.

Currently, Progressive Advancement is favored, as starting with a desktop version may lead to challenges in adapting advanced features to mobile devices, resulting in a diluted mobile version. Initiating design with a focus on the mobile end allows designers to prioritize key features under constraints, and as the platform expands, they can enhance the product gradually by leveraging the unique features of advanced ends. This makes Progressive Advancement a widely adopted strategy.

Mobile-First Design Principles

If you choose a mobile first design strategy, you should consider whether you will eventually migrate to a comprehensive desktop platform. This information will tremendously aid you in developing and implementing design strategies.

If your organization utilizes the DevOps methodology, you know the importance of early and frequent monitoring. But, if your business is not yet DevOps-enabled and you intend to design and develop your applications using a mobile first strategy, early monitoring can help to streamline the deployment process for both mobile and desktop versions of your platform.

Here are the steps of mobile first design development:

• List out content
  Create a spreadsheet that includes all the elements you want in your website. To begin, it is recommended that you construct a spreadsheet to list all the content items you intend to include in your design. After compiling this list, you will have a clear perspective of all the content that needs to be included in the design.

The goal of this phase is to prevent leaving out any essential aspects and to verify that your design is complete and covers all relevant content. Furthermore, having a detailed content list lets you prioritize and dedicate resources to the most crucial design aspects. Overall, inventorying your material is a vital phase in the design process that can assist you in creating a well-organized and successful design.

This step will also help in managing the visual hierarchy of content. You can prioritize the items in the content inventory spreadsheet and decide how to highlight the most significant ones.

• Begin with the tiniest breakpoints and work your way up
  For a mobile first design strategy, create a wireframe for the smallest breakpoint, such as mobile displays, and then scale it up for higher breakpoints, such as tablets and desktops, to begin your design process. This technique aims to guarantee that your design works well on tiny devices first and then adjusts it for larger screens.

Here is how you can apply this method:

• Start by creating a wireframe for the smallest breakpoint, which is often mobile displays. Your wireframe should cover your design’s main aspects, including content, pictures, and navigation.
• Once you are done with a well designed mobile wireframe, leverage this practice for larger breakpoints by increasing size.
• When you increase the screen size, watch for the quantity of white space on the screen. You should strive to expand the design until there is too much white space, indicating it is ready for the next breakpoint.
• Once you find out the next breakpoint, You should pause and begin adjusting the design for the next breakpoint.

The advantage of this method is that it assures that your design is optimized for smaller screens, which are becoming increasingly crucial in today’s mobile device era. It also helps you create a scalable and adaptive design, saving you time and effort in the long run. Overall, designing with minor breakpoints and scaling up is a successful strategy for building a responsive and adaptive design.

• Make elements thumb-friendly
  The next step of the mobile first design strategy is website thumb-friendliness. Clickable components like hyperlinks, buttons, and icons should be large enough to be readily tapped with a thumb (sometimes fingers!). Because thumbs are significantly more enormous than pixel-precise mouse cursors, users may mistakenly tap on the wrong element if the clickable elements are too small. The minimum recommendation is a clickable element should be at least 44 pixels in height and width.

To increase the size of touch targets, ensure that clickable items are not too close together. Also, to make buttons and other interactive components simpler to tap, slightly increase them. Finally, you should leave enough space around all interactive elements to avoid accidental tapping.

Another point that should be kept in mind is the “thumb zone.” Physically, users do not have easy access to the whole screen; it has a zone that is easy to reach, and some are harder to get. So ensure your CTA comes in the “easy thumb zone” to increase overall CTR. Here is the illustration for understanding the thumb zone in mobile devices.


• Avoid relying on hover
  For the mobile first design strategy, mouseover and CSS hover effects should be avoided because they are not supported on mobile devices. Hover and mouseover effects are interactive design components that change as the mouse is moved over them, and they are often employed in desktop interfaces.

Instead, for a mobile first web design, concentrate on creating intuitive and simple-to-use interfaces that use touch-based actions like tapping, swiping, and pinching. You can also include interactive design components built expressly for mobile devices, such as buttons and menus.

• Design the interface like a mobile application
  Instead of a typical desktop website, consider creating the UI as a mobile app. Off-canvas navigation, expandable widgets, AJAX calls, and other interactive elements are all things that mobile users are accustomed to having more control over.
• Off-screen navigation: A navigation menu concealed off-screen until the user presses a button to display it is called off-canvas navigation. This navigation style is popular in mobile apps because it allows users to access the navigation menu without taking up too much screen space.
• Expandable widgets: Widgets, such as an accordion menu, are interactive features allowing users to expand or compress content. This widget type is often used in mobile interfaces to save space and allow users to get information quickly without scrolling through a long page.
• AJAX calls: Asynchronous server requests allow users to interact with the interface without reloading the entire page. This type of interaction is frequently utilized in mobile devices to give a more fluid and responsive user experience.

By incorporating these features into mobile interface design, you can provide consumers with a more engaging and dynamic experience. Furthermore, building mobile interfaces such as apps can make it easier for consumers to explore and quickly access the required information.

• Avoid bigger visuals
  For the mobile first design, you should avoid utilizing large graphics that do not display well on small devices, such as landscape photos or complicated graphics. You should instead cater to mobile consumers by using graphics that are readable and clear on portable screens.

Because mobile devices have smaller screens than desktop computers, massive visuals can take up too much space and make navigating the UI difficult. Furthermore, huge images can take longer to load, slowing the interface and frustrating users.

Furthermore, Consider the context in which the photographs will also be used. For example, if you’re creating an interface for a news website, you should utilize graphics related to the content and assist the user in understanding the material. Similarly, when building an interface for an eCommerce website, utilize images that highlight the products and help the consumer purchase.

• Test on a real device before deployment
  The most crucial step for a mobile first design approach is to test it on a real device before release to ensure it is user-friendly and functioning well on different devices. Testing your mobile interface on a real device will help you evaluate its performance. You can test how quickly sites load, how easy it is to navigate the interface, and whether text and pictures are readable on a small screen. You can also see if the interface responds effectively to touch inputs and if there are any problems with buttons or links.

Testing on an actual device might also assist you in identifying flaws that may be hidden on a desktop computer. For example, you may discover that the font size on a mobile device is too small or that the buttons are too close together and difficult to tap.

Mobile-First Design Strategy

Mobile first design philosophy recognizes that mobile devices are the primary source of internet access for most users and that a mobile-friendly design is essential for providing a seamless user experience. Here are some key concepts that will help designers to create mobile first web designs, give users a seamless experience, and stay relevant in today’s mobile first digital landscape.

Prioritize user’s needs

Generally, many organizations’ application leaders have picked a mobile first design before defining use cases – this is the other way around. Application leaders must adjust their perspective from gathering requirements to studying usage patterns in a “design thinking” approach (as shown in the figure below). Requirements do not identify tasks for innovation and productivity. To find the user stories that compose an app’s functions are best determined by evaluating a varied collection of work practices for patterns in how employees interact, access content, collaborate, and produce content.

Clear visual hierarchy of mobile content

The arrangement of design elements in a way that prioritizes their relevance and guides the viewer’s eye through the design is known as a visual hierarchy. This is accomplished by altering the design elements’ size, color, contrast, proximity, and other visual features to establish a clear hierarchy. And in mobile first web design, it has significant importance.

Here are some principles that can leverage the visual hierarchy of content:

• Use sizing to get users’ focus on essential elements of web pages. You can simply increase the size of some elements to get users’ focus. However, too many significant elements can congest your webpage, which is not good practice.
• Use color and contrast to increase the importance of any particular element. Color with higher contrast creates a sense of uniqueness and grabs users’ attention.
• The appropriate typeface pairing can offer your website individuality and draw attention to specific sections. Typefaces of varying widths and weights can also increase hierarchy and highlight more essential text parts.
• Use whitespace to navigate users. The negative distance between elements in a design is referred to as whitespace. It can be used to gather or separate elements to emphasize their significance.

Keep your web design simple

Simple web design improves content clarity and is easier to navigate. Therefore it’s best practice to keep the content necessary for users so they don’t get distracted by extra elements.

Mobile devices have small screen sizes, and users frequently browse the internet while on the go, so they have less time to interact with the design. A straightforward design that focuses on the main content and functionality helps to ensure that consumers can locate what they are looking for fast and effortlessly.

Here are some methods to simplify web design:

• Concentrate on the web page’s content and make sure it is properly presented.
• Simplify navigation by using an easy-to-use and precise navigation system.
• Adopt a limited color palette to ensure the design is visually appealing without overpowering the consumer.
• Implement a clear and legible typeface to ensure the text is easily read on tiny displays.
• Utilize responsive images and videos that adjust to the size of the device’s screen.

Effective CTAs

Call-To-Action (CTA) should be created to stand out and contrast with the background and other elements on the page. This helps to guarantee that they are immediately visible and capture the user’s attention. Furthermore, it is critical to employ a consistent layout for CTAs throughout the website, ensuring they look and perform the same way on all pages.

Here is some point to improve the effectiveness of CTAs:

• Text CTA should be intriguing, with terms that compel the user to act.
• CTA should be built to contrast with the background and other items on the page.
• Put the CTA on the page in a visible and strategic location, such as above the fold or at the end of a section.
• Experiment with several CTA options, such as text, color, positioning, and design components.

Wrapping Up!

We are well aware that mobile devices are currently dominating the market. Therefore, a mobile first design strategy is not an option but a priority. In 2023, businesses that wish to improve their online presence and give an optimal user experience to their audience must prioritize mobile first web design.
