Best Tips and Principles For Mobile Form Design

Forms are a critical element of many digital products. They serve as the main interaction instrument allowing a user to achieve their goals in mobile application design. Forms are essential to get users to register on your site, subscribe to an email newsletter, leave feedback, purchase something, etc. Each form page fulfills a specific purpose, either to close a deal or to simply attract sign up. 

 A smartly crafted form design helps app owners achieve higher marketing results, increase conversion, and improve the UX. At the same time, poorly designed mobile forms can ruin the convenience brought by a digital product. Low-quality mobile form design may lead to transaction failures or even the loss of users. So, in this posting, we decided to outline some of the best tips and principles for form design to help you create understandable and simple mobile forms which your users will happily interact with. 


How to Approach Mobile Form Design?

In the today’s highly competitive market, each element featured in a mobile application is meaningful because the quality of user experience and conversion fully depends on it. That is why it is important to turn the mobile form design into one of your strengths. Unfortunately, numerous form designs are not that effective and rather turn out to be strange and complex. Typically, when designing mobile forms, the following elements/characteristics can play a trick on you, resulting in them not fulfilling their expected role:

  • Unstable/limited connection
  • Type of use (work in motion)
  • Touch input
  • Screen size

Of course, the user hesitation is inevitable as to the choice of whether to fill in a mobile form. Our purpose is to make it more likely that people will get it done. And here’s what we suggest.


Best Tips and Principles For Mobile Form Design

  1. Avoid to use a label as a placeholder

There’s a common practice to use labels as placeholders in the input box that disappear when a user clicks on it. This solution often creates problems for users as it is easy to forget what fields you need to enter. It is annoying so don’t do it. Instead, we would recommend you to design labels as icons. Such iconization of labels helps users to clearly know what fields have been entered, and what still need to be done.

  1. Always provide effective input methods

In order to help users quickly complete the fill and minimize input errors, we recommend you to provide different input methods, such as when entering the nickname, fill in the mailbox, input account, etc.

  1. Minimize input

Try to keep your forms as brief as possible. Reduce the number of fields to make your forms load quicker, especially when you ask the users for lots of information (questionnaire forms). Remember: the longer the forms, the less is the user’s willingness to fill them in. 

  1. Use single-column design 

The single-form design provides for an efficient, direct, and intuitive order of the fields to fill in. This way makes it easier for the eyes to move from the top to the bottom. In contrast, multi-column forms can easily be skipped/missed by visitors, especially when it comes to viewing them on a mobile device.

  1. Use intelligent autofill options

Just like any language of communication, forms should help all parties seal the deal in a logical way. Consider using intelligent autofill options to save the users time, say, the currency conversion process, and choice of geographical location. This will significantly decrease the time needed to fill in the form. 

  1. Provide visible prompts

Ideally, the users complete, check, and then submit the error-free data to your form during the process of registration or login. But in reality, errors are unavoidable. Instead of telling them of the mistakes they made, it is better to inform users of incorrect inputs right away by utilizing recognizable and visible information prompts. If a user makes a mistake, highlight the field and explain what’s wrong.

  1. Use limiters

These features are useful for fields meant for certain types of information, such as zip code, credit card data, phone number, etc. The following limitations can minimize most incorrect data being submitted:

  • Dependencies among fields
  • Format of characters (alphabetic, numeric)
  • The limit of possible characters
  1. Use sliders 

Sliders are a good choice if users are tasked with a wide range of options. For example, in order to select the price, they will simply need to move the slider instead of going all the way of typing it manually.

  1. Consider input peculiarities

When making form designs for mobile, ensure that the CTA elements, input fields, and fonts are large enough. In the other case, it may be difficult for users to manipulate them on the screen.

  1. Always offer options

Limit the need for users to think everything over. They will fill in the form faster if you provide several options from the start.

An excellent form design should have smooth processes, fast and efficient submission, perseverance in adjustment and improvement, and thoughtful details.
