Why Tiny Buttons Are a Bad Idea for Websites and Apps
In today’s digital age, the interfaces of websites and apps play a crucial role in our daily interactions with technology. Every action we take in the virtual world involves pressing various buttons or navigating through interface elements. Here lies the critical question: just how user-friendly and easy to use are these interface components?
Often, buttons that are too small not only become inconvenient but also highly frustrating for users. Think about how challenging it can be to tap a tiny button on your smartphone screen, especially if you’re on the go or don’t have particularly small fingers. This issue extends to children and the elderly, who may find it difficult to interact with minuscule interface elements. One reason why tiny buttons are so impractical is Fitts’ Law.
Fitts’ Law, named after psychologist Paul Fitts, states that the time required to hit a target depends on the distance to the target and the size of the target itself. Simply put, the larger the button and the closer it is, the quicker and easier it is to hit. For instance, large “Submit” or “Confirm” buttons on feedback forms not only enhance convenience but also significantly reduce the likelihood of errors, thereby improving overall user satisfaction.
To create truly user-friendly and effective interfaces, web designers should rely on research and adopt principles that yield positive results. Two valuable resources are the “Course for Mental Development” and “Brain and neuroscience.” These programs are excellent tools for understanding the nuances and details that make complex things simple, and vice versa. For example, studying the brain processes involved in interacting with digital interfaces can help design a more convenient user experience.
Ultimately, using tiny buttons only leads to problems and frustration for users. Usability principles, such as Fitts’s Law, are crucial in crafting high-quality web design and must be considered to ensure the interface is pleasant, intuitive, and as comfortable as possible. By thoughtfully considering the size and placement of each element, you can create a truly flawless digital user experience.
Fitts’ Law and Its Importance for Personal Development
In the realms of psychology and ergonomics, there exists an astonishingly precise model known as Fitts’ Law. This model allows the prediction of the time required to swiftly and accurately navigate to a desired target based on its distance and size. Effectively leveraging Fitts’ Law unlocks numerous opportunities for enhancing productivity and skills in daily life.
Anyone who regularly works on a computer is all too familiar with the challenges of placing the cursor on the screen. According to Fitts’ Law, the farther a target is on the screen and the smaller its size (imagine a tiny icon in the corner), the longer it takes to accurately click on it. Conversely, a large “Send” button right next to the cursor takes minimal time to click. This principle extends to our physical world as well. Picture throwing any object at a target, whether it’s a dart at a dartboard or a basketball at a hoop. The farther and smaller the target, the more challenging and time-consuming it becomes to achieve precision.

Fitts’ formula has been meticulously refined over time and includes variables such as average action time, movement initiation and stopping times, movement speed, the distance from the starting point to the target, and the target’s width. The logarithmic function in the formula indicates a nonlinear relationship among these variables, aiding in the understanding of the intricate aspects of precise movement coordination. The historical context of this law traces back to Paul Fitts’ studies in the latter half of the 20th century, which illuminated how people execute fast and accurate movements under various conditions.
The practical significance of Fitts’s law for self-improvement is immense. Understanding the principles governing our actions allows us to plan our efforts and time more efficiently. For instance, when tackling tasks, it’s better to start with those closer to our area of expertise (larger targets) to achieve quick successes, and gradually move on to more challenging tasks (distant and precise targets). This mindful management of our actions, based on knowledge of Fitts’s law, helps us allocate energy more effectively, avoiding wasted time and resources. Such an approach undoubtedly promotes our overall intellectual and physical development, leading to success in various aspects of life.
Fitts’ Law: How Target Size Affects Time to Reach It
Paul Morris Fitts, a distinguished researcher in psychology and control systems, developed one of the foundational laws of ergonomics and cognitive sciences. His Fitts’ Law, which uncovers the relationship between the size of a target and the time required to reach it, was a groundbreaking discovery. Through his research, he conducted three unique experiments using touch-sensitive objects and specialized movement devices. His findings revealed a clear pattern: the further and smaller the target, the more time it takes to reach it; conversely, the closer and larger the target, the quicker it’s attained.
Fitts’ Law has found widespread application across various fields. For instance, the Air Force uses it for precise movement modeling and safe flight planning. This approach has significantly improved pilot safety, as evidenced by an incident in the 1960s when following Fitts’ recommendations saved a crew during a carrier landing.
Fitts’ Law can be easily illustrated with a graph showing the function of time dependency on target size and distance. Interestingly, after a certain target size is reached, the time required to achieve it no longer changes proportionally, due to the logarithmic relationship of the variables. Experiments also demonstrated that changes in distance or target size do not affect the overall pattern, which remains consistent regardless of experimental conditions.
The significance of this law extends far beyond aviation. A prime example is everyday smartphone use: buttons and apps on the screen are placed according to Fitts’ Law to minimize the time needed to find and activate them. Another intriguing example is in sports shooting, where athletes consider the size and distance of targets to improve their speed metrics during training.
Fitts also conducted research involving different age groups and individuals with special educational needs. Regardless of these factors, the relationship between target size and the time required to reach it remained consistent. Even when subjects were under the influence of drugs, the same pattern was observed, highlighting the deeply ingrained nature of this phenomenon.
Today, Fitts’s law is an essential element in user interface design. It is used to create ergonomic and intuitive interfaces, enhancing user interactions with devices to make them more comfortable and efficient. Expressed mathematically by Shannon’s formula, this law is widely applied in Human-Computer Interaction (HCI) to improve human-computer interaction, from ATM machines to virtual reality systems.
Implementing Fitts’ Law in Web Design
Fitts’ Law plays a crucial role in web interface design, ensuring users have a comfortable and intuitive experience when interacting with a site. The main principles of this law are elaborated in the articles “Using Fitts’ Law: A Core Principle of UI/UX for Developing Online Stores” and “UX Design: Fitts’ Law for Determining the Optimal Size and Placement of Elements on a Website.” One of the most important principles of Fitts’ Law is that users should be able to reach their goal quickly and easily, such as pressing a button effortlessly.
Web design that adheres to Fitts’ Law aims to create buttons and other interactive elements that are easily noticeable and accessible. For example, large and brightly colored buttons simplify user navigation by being easily accessible, reducing the time and effort required to find and click them. On the other hand, small and closely spaced buttons make interaction more difficult and increase the likelihood of clicking the wrong one. A good example can be found on registration or login pages, where input fields and action buttons are spaced adequately to minimize errors.
Interaction between users and interfaces on both standard and mobile devices can be divided into four stages: initial positioning, aiming for the target, slowing down before a precise tap or click, and the final engagement, whether it’s a click or a touch on the screen. For mobile devices, it’s particularly important to place buttons within easy reach of the thumb, enabling users to operate the interface effortlessly with one hand. For instance, the “Send” button in a messaging app is often located at the lower right corner of the screen, making it easily accessible for most users.
Special attention should be paid to buttons associated with critical user actions, such as “Buy,” “Sign Up,” etc. It’s essential to leave adequate space around these buttons so that users can easily distinguish and select the desired function without needing to scroll. An example of this is the “Add to Cart” button on a product page, which should be large and prominent. In contrast, buttons for removing items, like products from a shopping cart, should be slightly smaller and positioned a bit away from the main action button to reduce the risk of accidental presses. This is particularly crucial for interfaces such as the shopping cart in an online store, where mistakenly deleting an item could lead to a negative user experience.
