The Ultimate Need for UI/UX Design - Why’s and How’s

High-quality website design boosts user satisfaction, which makes it extremely important in achieving business goals: growing traffic and conversion and sales. Equal Design is a user experience agency where we have tons of experience to help you reveal all aspects of the value of UI/UX design for your business.

Why Is Your UI/UX Design Valuable?

User experience (UX) has long been one of the key factors in business performance. Official data says that every dollar invested in the mobile app UI turns into a hundred, and a good custom eCommerce website design increases website conversion by up to 4 times!

Statistics clearly show that:

  • Approximately 90% of customers prefer not to stay long on a site with poor design and/or interface.
  • Over 90% of negative user reviews are related to unattractive or inconvenient website design.

Today, developers pay a lot of attention to factors such as loading time and interface. And this brings results, including:

  1. Better SEO support;
  2. Increased brand loyalty;
  3. Lower development costs.

If, previously, outsource website design development was based on the wishes, tastes and values of the consumer, today it is focused on their psychology, direct needs, and ultimate expectations.

Good UI/UX Design Basic Principles

Modern app UI/UX design is shaped by every little detail and thoroughly outlines all functional and non-functional nuances. This simplifies and streamlines the user experience.

In their study, The Nielsen Norman Group noted signs of better design in terms of visual appeal. This is simplicity coupled with consistent typography, a clear hierarchy, and a sophisticated color palette. Visual details shape usability and express brand traits.

Typography and spacing

Grid alignment

Sidebar content is left aligned. This makes the information easier to scan and the app UI/UX more legible as a whole.

Typographic dispersion

Different font styles can be used, but it’s best to stick to one family and do only minor changes in colors. You need to make sure different types of content can be easily distinguished inside the interface.

Extra spacing

Paragraph spacing should be increased from the default spacing (which is typically 2px larger than the font size). This forms an open text block.

Kerning and tracking settings

App UI/UX design takes into account awkward spacing between letters due to their special shape. For example, in titles where spaces are more visible, the spacing can be slightly compressed for better readability.

Hierarchy and color

In terms of a good mobile app UI/UX design, scale and color palette are optimized to create page hierarchy. The choice of color is limited to a small number of basic shades that combine in the best way. At the same time, all pages maintain the same style, and to emphasize the importance of products, a mixed approach to headings is used (no more than two fonts).

Hi-res images

Clear photos without clutter in the frame should not detract from the product. The backgrounds of the images and product cards blend smoothly, giving the page a comfortable look.


Consistent visual processing

Another rule of efficient mobile app UI design is the consistency of visual elements in different areas of the application, top grid lines and typography within genres. The spacing between columns must match on all screens. You can change the color of the gradient but keep the hue and saturation constant.

Indentations for grouping content

Spacing between app UI/UX elements helps form groups. This uses less space between the heading and text and more space between groups.


The implementation of all the above principles makes your mobile app UX design guaranteed to engage and please the user’s eye. However, the underlying tasks for a web designer can be quite challenging. Contact our user experience design agency and share your idea or project expectations with professionals.
