This adaptability ensures a consistent and coherent user experience across desktops, laptops, tablets, and smartphones, regardless of the device utilized.

Accessibility compliance

The design for mobile first solutions champions accessibility by prioritizing clear typography, intuitive navigation, and inclusive design principles. By ensuring that content is readily accessible and navigable on smaller screens, businesses can broaden their reach to include a more diverse audience, including users with disabilities or impairments.


In today's digital field, where mobile usage outpaces desktop usage in many regions, businesses that prioritize mobile first web design gain a competitive advantage. By delivering exceptional mobile experiences, companies can attract and retain more customers, differentiate themselves from competitors, and cultivate brand loyalty. Thus, entrepreneurs can position their businesses for long-term growth and sustainability.

In general, a mobile-first strategy ensures your website is accessible, engaging, and future-proofed for the constantly changing mobile landscape.

Key principles of mobile-first design

The mobile first design rests on fundamental principles that are essential for crafting outstanding user experiences on mobile devices.

Content prioritization

Mobile first website design underscores the importance of prioritizing vital content and functionalities for smaller screens. By identifying and emphasizing key user needs and goals, designers ensure swift access to pertinent information without unnecessary clutter.

Intuitive navigation

In mobile-first design, navigation should be intuitive to facilitate seamless user interaction. Clear and concise navigation menus, strategically positioned buttons, and intuitive gestures enhance usability, fostering a fluid and enjoyable user experience.

Touch optimization

Given the touch-centric nature of mobile devices, touch optimization is pivotal in mobile-first design. Design elements such as buttons, links, and interactive components should be adequately sized and spaced to accommodate accurate touch inputs, minimizing user frustration and errors.

Together, these principles foster superior user experiences on mobile devices by prioritizing usability, accessibility, and performance.

Creating mobile first design: main steps

We've crafted a guide for you through the creation of a mobile first responsive design. Our tutorial consists of six essential steps:

Step 1: Define your content priorities

Differentiating from the traditional "desktop-first" approach, the "mobile-first" methodology involves progressively enhancing layouts with additional information as they expand. Rather than stripping away content for smaller screens, the focus is on organizing content into primary, secondary, and tertiary categories. 

For example, in the initial stages of designing the crypto exchange platform, the focus would be on prioritizing essential elements such as real-time trading, portfolio management, and secure transactions. You should ensure they are easily accessible and optimized for mobile devices. These primary features serve as the foundation of the platform's functionality, catering to the needs of mobile users, who form a significant portion of the target audience.

Secondary elements, such as advanced trading tools, market analysis, and account settings, can be gradually introduced as the screen size increases.

Step 2: Establish a visual hierarchy

Once content organization is settled, the next step involves crafting a visual hierarchy to steer the mobile-first web design process. Visual elements like logos, themes, typography, videos, and other media contributing to the overall aesthetics should be factored into this hierarchy. Here are key aspects we consider at Peiko for establishing a visual hierarchy:

  • Utilize size variations to emphasize or diminish visibility.
  • Leverage color and contrast effectively.
  • Employ complementary typefaces and styles.
  • Adjust font sizes strategically.
  • Incorporate ample white space.
  • Ensure a cohesive design structure.
  • Minimize large graphics.
  • Optimize touch object sizes for enhanced usability.

These factors are pivotal in crafting a comprehensive design for mobile first websites. While initially geared toward mobile usage, this design foundation can be further expanded to accommodate tablets, PCs, and various other devices.

Step 3: Craft the smartphone view

In this phase, we concentrate on the critical elements that users require on a smartphone screen. In the example of crypto exchange, essential features such as real-time market data, trading pairs, and account balance information take center stage to facilitate immediate trading activities. Less crucial elements, such as advanced trading tools or in-depth market analysis, are strategically reserved for deeper pages or secondary menus to maintain a clean and intuitive interface.

Step 4: Refine for tablet view

Expanding to a tablet-sized display allows us to incorporate secondary information like additional product offerings and expand the navigation menu. But don’t overcrowd the interface with unnecessary details. Try to stick to the ordered content list and maintain a clear hierarchy between secondary and tertiary elements to ensure optimal user experience.

Step 5: Optimize for desktop view

The desktop view offers ample space to accommodate all essential information. When we develop the crypto exchange, the homepage can showcase registration forms, trading tools and charts, account management, and educational resources with guides and tutorials. By leveraging the expansive screen of the crypto exchange project, we can provide users with a rich browsing experience without compromising clarity or usability.

Step 6: Conduct quality testing

Following the design phase, it's imperative to undertake meticulous quality assurance across different devices and screen dimensions. This guarantees that the mobile first design operates smoothly and delivers an excellent user experience on all platforms. Quality assurance entails evaluating responsiveness, loading times, functionality, and visual coherence. 

Top practices for the mobile first approach

To create intricate and multi-layered designs, UI/UX (user interface/user experience) specialists must adhere to specific best practices. These practices will assist them in implementing a mobile-first approach effectively:

Emphasize content priority

Are you familiar with Bill Gates' famous saying, "Content is king"? It holds particularly true when discussing the design strategy at hand. The initial crucial step towards a successful project involves determining content priorities for a compact layout.
Diligently craft your copy to prioritize essential information while eliminating irrelevant content. 

Mobile devices present numerous limitations, including bandwidth and screen size.
Take these factors into account, consider context carefully, and craft captivating copy that resonates with visitors. 

Developing user scenarios proves invaluable in this regard, aiding developers in discerning the nuances between desktop and mobile interactions while steering clear of unnecessary content adjustments. Additionally, incorporating content-specific breakpoints through media queries at this stage enables the design to adapt to various screen sizes seamlessly.

Keep in mind user typing requirements. Typing on mobile devices is time-consuming and prone to errors. Integrate forms or auto-complete features to expedite visitors through typing-related tasks swiftly.

Create intuitive navigation

Seamless navigation is paramount for delivering a seamless user experience on mobile devices. Employing features like navigation drawers (utilizing Hamburger menus) enables the presentation of secondary website elements, aiding users in locating essential information effortlessly.

Crafted effectively, navigation streamlines the mobile user experience, facilitating easy access to desired content. To attain this goal, meticulous planning of each step is essential. Avoid overcomplicating navigation; it should be concise and straightforward. For added convenience, consider temporarily concealing the navigation bar when displaying full-page content or substituting a search bar for a search icon.

Use design-specific graphics

Captivating visuals can indeed capture visitors' attention effectively. However, not all images translate well onto mobile screens. Images with intricate details, especially those with small elements, or complex graphics, as well as landscape photos, may not display optimally on screens that are just a few inches across.

Additionally, employing the same "heavy" images across all screen sizes is ill-advised. With many consumers accessing the Internet via mobile devices, they are likely to abandon pages where images take too long to load, especially if their size exceeds 1 MB.

Instead, opt for flexible images and media, utilizing mobile first responsive web design principles. This will ensure that your content remains intact regardless of resolution or circumstances.

Use vertical visuals

Vertical imagery has become ubiquitous among mobile users who prefer the convenience of scrolling through their feeds with ease. These vertically oriented images command attention, compelling viewers to pause their scrolling and engage more deeply with the content.

When crafting a mobile-centric shopping experience for your ecommerce platform, prioritize the use of vertical content. Whether it's captivating images showcasing your products, informative videos demonstrating their features, or engaging customer reviews, leverage vertical formats to enhance user engagement and streamline the browsing experience for mobile shoppers.

Minimize disruptive pop-ups

In the context of mobile devices, characterized by limited space, users find sudden pop-ups or intrusive advertisements disruptive and unwelcome. Website owners and designers should focus solely on providing users with relevant and sought-after content, refraining from unnecessary distractions.

Adhere to the thumb rule

While engaging with touchscreens, consumers typically employ one-handed operation, predominantly relying on a single thumb (typically the right one) for navigating mobile apps, browsing websites, and other activities. Ensure the accessibility of top-level menus, essential controls, and frequent actions for visitors using one hand to guarantee the site's usability. Refer to the image below for optimal placement of these elements.

Remember that fingers surpass cursors in size. Maintaining adequate spacing between clickable elements and buttons on compact screens is crucial. Following Apple's recommendation, ensure your touch targets measure at least 44x44 pixels. If they exceed this, don't fret; Google suggests controls should ideally be sized at 48x48 pixels.

Conduct real device testing in real conditions

Thorough testing on real devices under authentic conditions is indispensable to ensure optimal user experiences across various devices. 

With this method of testing under genuine conditions, designers can identify and rectify any discrepancies or inconsistencies in the website's performance, ensuring seamless functionality across the entire spectrum of devices. This hands-on testing methodology provides invaluable insights into how the website behaves in real-world scenarios, allowing for adjustments and optimizations to enhance user satisfaction and engagement.

Moreover, real device testing enables designers to assess factors such as loading times, responsiveness, and compatibility, which are crucial for delivering a superior user experience. By simulating actual usage scenarios, designers can uncover potential issues and address them proactively, mitigating the risk of user frustration and dissatisfaction. In general, this approach enables designers to verify that the website renders as intended across mobiles, tablets, and desktops.

Follow these mobile first design best practices and craft successful software solutions. By emphasizing content priority, designers ensure essential information takes center stage while eliminating unnecessary clutter. Crafting captivating copy and incorporating user scenarios aid in tailoring the design to meet user needs effectively.
