Guidelines for Perfect Mobile Design

Aditya Kumar | 23rd April 2020

While designing Mobile applications we should take care of the small things because those small things make a good User interface. I am sharing some of the basic mobile design aesthetics which we all should use for better results.


There are following points need to take care while mobile design:


Reach Area 

Thumb Reaching Zone: How easy to reach our thumbs to tap areas on a mobile phone’s screen.

Hard to reach 

Reaching this area requires uncomfortable finger movements and a lot of stretching 

Okay to reach

Reaching this area requires some stretching. Can be hard for users with small hands

Easy to read

Reaching this area is very easy on nature and does not require stretching.

Platform Guidelines

We have to use the right design system for iOS and Android. Both iOS and Android have a different user base. Also never carry UI Elements from e platform another.

Apple’s Human Interface Guidelines

We are already aware of the In-depth information and UI resources to designing pixel-perfect applications to integrate seamlessly with the Apple platform

Guidelines Material Design

Material design is an adaptable system of guidelines, components, and tools that support the best practices of user interface designs for android.

Think device first

First, we have to be aware of the “unsafe areas” (notch, camera punch-hole, etc.)


Unsafe Area 

Be careful when designing in these areas, you should not include menu or tab elements in there.

Safe Area

Everything within the “safe areas” will be visible on different device screens.


Font Type and Font Size

Every font can evoke different emotions and provide easy readability at the same time.


We have to choose a typeface that works well in multiple sizes and weights to maintain readability and usability in every size


Use legible font size. The text should be at least 11 points so a user can read it at a typical viewing distance without zooming


Use contrast checkers to prevent color problems, also use 60-30-10 rule which refers to an ideal proportion that is meant to reach a balance among colors

Call to Action (Buttons)

We have to design finger-friendly buttons because Mistaken taps often happen due to small touch controls

Create controls that measure a minimum of 10-12mm (40px) in order that they are often accurately tapped with a finger.

Long Scroll Problems

Keep screens as short as possible, using cards with a tap to extend feature or by breaking tasks into screens

Tab bars

Tab bars are very important for every app, We have to design clear and clean tab bars also name all tabs whenever possible for better user experience.


Tap or swipe mobile gestures? It is very important to choose the right gestures because if sometimes using the wrong type of gesture can lead to a broken UX.

Tap Gesture

Select or submit


Toggle on/off

Cancel or escape

Enable or disable

Swipe Gesture



Dismiss notifications
