Challenges of Web Design for Mobile Devices

Of course, Web design for mobile devices brings its own unique set of challenges that designers must overcome to create a successful mobile website. If you’ve attempted to design for mobiles, these were probably some of your most significant challenges.

1. Variety of screen sizes

Although Web designers are used to dealing with varying screen sizes and the resulting issues, mobile design presents this challenge in a bit of a different way than dealing with different-sized desktop monitors. Most designers are comfortable with the challenges that arise from various screen resolutions on desktop monitors, but if you haven’t worked with mobile design before, it can be something yet more complicated that you need to overcome.

Because mobile technology is always changing, screen sizes are changing, too. Fortunately for designers, modern mobile devices typically have bigger screens and higher resolutions than those of a few years ago, but of course those older phones are still in use.

While we’re on the topic of mobile screen sizes, there are two excellent articles from April of 2008 at Sender 11: Mobile Screen Size Trends and More on Mobile Screen Size Trends. The results of the study behind these articles show that 240 x 320 (a.k.a. QVGA) should be the standard for mobile development. Many newer mobiles and smart phones have larger screens, but smaller ones are largely a thing of the past.

The graph below shows the findings of the report, which is close to a year old at this point. With the rise in popularity of the iPhone and its competitors, the most recent numbers most likely favor larger screens even more.

2. Lack of understanding
One of the biggest challenges that many designers face is just the intimidation of dealing with a new aspect of design. If you haven’t considered mobile browsers and visitors in your previous design work, it’s most likely not something you feel comfortable doing without some research. Because mobile browsers behave somewhat differently than desktop browsers and because the environment of its users is not the same, the designer needs to gain some understanding and familiarity. Through the information and resources presented in this article, you can easily get started with a general understanding of the mobile Web, if you don’t already have experience.

3. Rapid change
Like any other technology, rapid change is a constant. Of course, Web designers need to stay on top of the industry in general, and the mobile Web is no different. As technology and trends continue to change, the mobile Web will evolve accordingly. The challenge of change isn’t really anything new to designers; the mobile Web just presents another area in which designers need to stay up to date.

4. Testing challenges
One of the most significant challenges in designing for mobiles is the wide variety of phones in use. While designing for desktops brings its own testing challenges, with its various browsers and screen resolutions, there are more dependable ways of testing these items at the moment. On the mobile Web, however, many of your visitors will likely be accessing your website in an environment that you were not specifically able to test.

There are, of course, some things you can do so that a mobile website is tested as well as possible. To start with, the simplicity of mobile websites in a way makes the testing process easier because there is less that can go wrong. With a careful design and some well-planned testing, it’s possible to be fairly certain that a website will be displayed properly and, more importantly, usable on the vast majority of mobile devices.

For testing, we’d like to point out a few here . First, the Web Developer Toolbar has some very useful features for testing a website for mobile users. Because CSS and images may not be enabled when a mobile visitor is on your website, you can use the toolbar to disable both and see how the website will appear. While this does not exactly replicate the experience of visiting the website in a mobile browser, it can help identify potential problems in the way content and navigation is displayed.

Another helpful testing resource is the Opera browser. In the Opera toolbar, go to “View” and select “Small Screen.” This will display the website in a very narrow window, similar to what would be used on a mobile device. Additionally, you can use the Opera WebDev Toolbar to view an unstyled page by clicking on “Display.” By viewing the page in the small screen with CSS turned off, you can get an idea of how mobile visitors may experience the website.

5. Deciding on what is essential
If websites are to contain only what is most essential, the website owner or designer will have to determine accurately what content is most important . This may seem pretty simple, but taking a website that’s loaded with content, images and maybe even video, and weeding it down to just the essentials can be quite a challenge. Another aspect to this issue that must be considered is the status of the average mobile visitor. What are they doing? Why are they accessing the website at that time? What are they likely and unlikely to have any interest in? Keep in mind that the goals of mobile visitors are often vastly different than those of visitors sitting at a desk.
