What Is Helper Text?

In the world of user interface (UI) design and web development, “helper text” plays a crucial role in enhancing the user experience. This article explores what helper text is, its purpose, and how it can be effectively utilized.

What Is Helper Text?

Helper text, also known as instructional or assistive text, refers to the supplementary text provided alongside input fields or UI elements to guide users in completing tasks or entering information correctly. It serves as a form of support designed to clarify, instruct, or provide additional context for the user.

Purpose of Helper Text

The primary purpose of helper text is to improve the usability and accessibility of a digital product. Here are some key reasons why helper text is used:

1. Clarification: It helps to clarify what information is required in a field or how to use a feature. For example, a form field for entering a phone number might have helper text indicating the preferred format.
2. Instruction: It provides instructions or examples that guide users on how to complete a task. For instance, a password field might include helper text about acceptable password length and complexity.
3. Error Prevention: By offering real-time guidance, helper text can prevent user errors and reduce frustration. For example, it might explain the need for specific input types or formats.
4. Accessibility: Helper text ensures that users with different needs, including those with disabilities, can interact with the interface effectively. For example, screen readers can read out helper text to assist visually impaired users.

Common Examples of Helper Text

• Form Fields: In online forms, helper text might explain the required format for dates, phone numbers, or passwords. For example, “Enter your date of birth in the format MM/DD/YYYY.”
• Search Bars: Helper text can suggest search terms or provide examples of what users can search for, such as “Try searching for your favorite products.”
• Buttons and Links: Text accompanying buttons or links can describe their function, like “Submit your application” or “Learn more about our services.”

Best Practices for Using Helper Text

1. Be Concise: Helper text should be clear and to the point. Avoid overly technical jargon or lengthy explanations.
2. Use Plain Language: Write in simple, understandable language to ensure that all users can easily comprehend the information.
3. Be Contextual: Ensure that the helper text is relevant to the specific field or UI element it accompanies. It should directly address the user’s needs.
4. Position Wisely: Place helper text close to the related field or element. Typically, it appears below the input field or next to the element it’s assisting.
5. Design for Visibility: Make sure that the text is visible and easy to read, using appropriate font size, color, and contrast.
6. Consider Accessibility: Ensure that the helper text is accessible to all users, including those using assistive technologies.

Frequently Asked Questions (FAQs)

Q3: Should helper text always be visible?

A3: Helper text should be visible when needed. However, in some designs, it might only appear when a user interacts with a specific field or element. The key is to ensure users can easily access the guidance when required.

Q4: How do I ensure my helper text is accessible?

A4: To ensure accessibility, use clear and simple language, maintain a high contrast between text and background, and make sure the text is readable by screen readers. Test the UI with various assistive technologies to confirm compatibility.

Q5: Can helper text improve form completion rates?

A5: Yes, effective helper text can significantly improve form completion rates by reducing confusion, guiding users through the process, and minimizing errors.
