The 4 Most Important Laws of UX Design
Summary
TLDRThis video script introduces four crucial laws of UX design: Fitts' Law, Hick's Law, Jacob's Law, and Miller's Law. Fitts' Law emphasizes the importance of target size and distance for ease of access. Hick's Law addresses decision-making time in relation to the number of choices. Jacob's Law suggests that users prefer familiar navigation patterns. Miller's Law highlights the limitation of the human working memory, recommending streamlined content. The video encourages designers to apply these principles for effective UX.
Takeaways
- 🎯 Fitt's Law: The time to acquire a target is a function of the distance to and the size of the target, emphasizing the importance of touch target size and placement for user accessibility.
- 📍 Touch Target Guidelines: Ensure touch targets are large enough to interact with, have sufficient spacing to avoid accidental taps, and are placed in easily accessible areas of the design.
- ⏱ Hick's Law: Decision time increases with the number and complexity of choices, suggesting the need to minimize options and simplify decision-making processes to reduce cognitive load.
- 🔍 Implementing Hick's Law: Use techniques like minimizing options, breaking complex flows into digestible steps, and highlighting suggested options to streamline user decision-making.
- 🔄 Jacob's Law: Users prefer sites that work similarly to other familiar sites, advocating for the use of established UI and UX patterns rather than creating unique, unfamiliar ones.
- 🛠 Applying Jacob's Law: Take inspiration from familiar UI and UX patterns, use similar navigational structures, and avoid significant deviations from the norm to maintain user comfort.
- 🧠 Miller's Law: The average person can only keep about seven items in working memory, indicating the need to challenge content and limit the number of options presented to users.
- 📚 Categorization in Design: Use Miller's Law to categorize and sub-categorize items in design, making it easier for users to process and remember information.
- 📉 Avoiding Information Overload: Don't force content to fit the 'magic number' of seven; instead, strive for the most streamlined and effective presentation of options.
- 🌐 UX Principles Overview: While there are many UX laws and principles, the four discussed in the video are considered most critical for enhancing user experience.
- 🔗 Resource for Further Learning: The video is inspired by the 'Laws of UX' website, which provides further examples, implementations, and a wealth of additional principles for UX design.
Q & A
What is Fitt's Law and how does it apply to UX design?
-Fitt's Law states that the time to acquire a target is a function of the distance to and the size of the target itself. In UX design, it suggests that the placement and size of interactive elements like buttons and links should be optimized for ease of access and interaction.
How can you use Fitt's Law to improve touch targets in a design?
-To apply Fitt's Law, ensure that touch targets are large enough to be easily tapped or interacted with, provide sufficient space between them to prevent accidental clicks, and place them in accessible locations within the design.
What is Hick's Law and how does it influence decision-making in UX?
-Hick's Law states that the time it takes to make a decision increases with the number and complexity of choices. In UX, it implies that reducing the number of options and simplifying choices can decrease cognitive load and improve user decision-making.
How can Hick's Law be implemented to improve user experience?
-Hick's Law can be implemented by minimizing options on the screen, breaking complex tasks into smaller steps, providing suggested options, and using progressive disclosure to reveal information as users progress through a process.
What does Jacob's Law state and why is it important for UX design?
-Jacob's Law states that users spend most of their time on other sites, implying that they prefer interfaces that are consistent with their existing experiences. It's important for UX design because it encourages designers to use familiar UI patterns and navigation structures to enhance user comfort and efficiency.
How can you apply Jacob's Law to everyday design work?
-Apply Jacob's Law by taking inspiration from UI and UX patterns of familiar products, using similar flows and mental models for navigation, and minimizing deviations from the norm to avoid confusing users.
What is Miller's Law and how does it relate to working memory in UX design?
-Miller's Law states that the average person can only keep seven plus or minus two items in their working memory at any one time. In UX design, it suggests that presenting users with too many options can overwhelm their cognitive capacity, leading to a need for content categorization and simplification.
How can Miller's Law be used to enhance the user interface?
-Miller's Law can be used to enhance the user interface by categorizing and sub-categorizing options, presenting a manageable number of choices, and challenging the need for excessive content to streamline the user experience.

-User feedback plays a crucial role as it provides real-world insights into how well the design adheres to these laws. It helps designers identify areas for improvement and ensure that the user experience is intuitive and efficient.
Outlines
📏 Fitts' Law in UX Design
The video script discusses the importance of Fitts' Law in user experience (UX) design. Fitts' Law states that the time it takes to acquire a target is a function of the distance to the target and the size of the target itself. This principle is crucial for designing interfaces where users can easily find and interact with buttons, call-to-actions, or links. The script suggests making touch targets large enough to be easily tapped, ensuring there is adequate spacing between targets to prevent accidental clicks, and placing these interactive elements in accessible locations within the design.
🛠 Hicks' Law: Simplifying User Decisions
Hicks' Law is introduced as a principle stating that the time it takes to make a decision increases with the number and complexity of choices. To adhere to this law, the script advises designers to minimize the number of options presented to users, especially when quick decisions are necessary. It recommends breaking down complex tasks into simpler steps and providing suggested options to guide users. The concept of progressive disclosure is also mentioned as a way to reveal options and information gradually, which is beneficial for onboarding and checkout processes.
🔄 Jacob's Law: Consistency in UX
Jacob's Law is highlighted, emphasizing that users prefer websites that work similarly to other sites they are familiar with. The script advises designers to use established UI and UX patterns rather than creating entirely new navigation systems. It suggests that designers should make minimal deviations from the norm and ensure that any changes do not confuse users. The goal is to leverage familiar patterns to make the user experience as intuitive as possible.
🧠 Miller's Law: Managing Cognitive Load
Miller's Law is discussed, which posits that the average person can only hold about seven items in their working memory at any one time. The script suggests that designers should challenge content and business ideas to ensure that users are not overwhelmed with too many options. It recommends categorizing and sub-categorizing items within a design to manage cognitive load effectively. The advice is to avoid filling the interface with unnecessary content just to reach the 'magic number' of seven, but rather to strive for the most streamlined and user-friendly design possible.

Transcripts
there are tons of laws and principles
and best practices of ux design so many
in fact that it could make your little
ux heads spin in circles so in this
video I'm going to share the four most
important laws of ux design that you
need to know
our first up let's talk about fits law
fits law states that the time to acquire
a Target is a function of the distance
to and the size of the target itself a
key idea is to latch onto here are
distance and size that means for our
users to find that button or call to
action or link that you need them to
find it really is dependent on where
it's placed in the page or on the screen
the problem is that if you don't apply
fits law you start placing your call to
actions and important content on the
page in areas that are too far for the
user to really get to or make sense of
or that the button itself doesn't stand
out because it's not big enough we want
to make sure that these important call
to action areas really stand out so
here's a few suggestions on how to use
fits law in your everyday design work
touch targets call to actions buttons
anything that is tappable should be
large enough to actually be tapped or
interacted with if it's too small starts
to frustrate the user your touch targets
a AKA your buttons call to actions and
links should have enough space in
between them so you don't accidentally
click on one instead of the other make
sure there's a good amount of distance
between them and lastly these touch
targets should be placed Somewhere In
Your Design where they are incredibly
accessible and easy for the user to find
next up let's talk about Hicks law Hicks
law states that the time it takes to
make a decision increases with the
number and complexity of the choices
this means the more choices they are the
more that you cognitively overload your
users so don't give them tons of choices
slim it down and give them the most
important choices here's a few ways you
can actually Implement Hicks law and
start using it right now if decisions
need to be made quickly and response
times are something that are actually
critical you need to minimize the amount
of options on the screen available if
you have really complex flows and
complex things you're trying to
accomplish break them into smaller
easier to digest steps and allow the
user to go through step by step so you
won't over reload them you can actually
help users to make decisions not even by
lessening the options but by giving them
a suggested option by highlighting the
option you'd like them to take so for
instance would you like to check out now
or would you like to go back to your
cart or shop some more we want to go
ahead and highlight checkout now we can
use a little trick called Progressive
disclosure to start revealing items or
information or options to them as they
step through the process this is really
great for onboardings and checkout
experiences and numerous other
applications before we move on to the
other laws of ux a quick favor to ask of
you if you could leave a comment down
below just tell me where you're coming
from what your experiences with ux or
just say hi that would be great and
actually help with the algorithm for
other people to see this content if you
find it to be valuable maybe they would
too so leave a comment down below I'd
love to hear from you next up let's talk
about Jacob's law Jacob's law states
that users spend most of their time on
other sites this means that users prefer
your site to work the same way as all
other sites that they already know if
you're trying to accomplish similar
things that other people are trying to
accomplish with their users it doesn't
make sense to create some sort of new
amazing navigational structure or system
that nobody's ever seen before it makes
way more sense to lean on the tried and
true tactics and techniques that other
people have paved the way with here's a
few ways you can actually apply Jacob's
law to your everyday work the more a
like your product or design is to other
products or designs consider taking some
inspiration to some of the UI patterns
and ux patterns that they're using
throughout their work they already know
how to do that why not just make it easy
for your user next up don't make your
users learn new mental models of how to
get from one screen to another or how
navigation works from one area into
another use similar flows and mental
models and structures to make your
applications and Designs make sense if
you have to make a change and deviate
from the norm or the standard that you
can find elsewhere make sure you do it
as little as possible unless you
abstract yourself away so much from
what's usable that you end up confusing
your users so if you have to stray Just
Don't Stray too far and last on the list
let's talk about Miller's law Miller's
law states that the average person can
only keep seven plus or minus two items
in their working memory at any one time
seven items plus or minus a few is the
maximum that people can actually hold on
to and think about it one time before
they start forgetting some of the
options that have just been shown to
them this is a really good time to
challenge content and challenge your
business ideas and strategies because if
you have 50 things that the user needs
to select from do they really need to
select from all 50 of those things
here's a few ways to actually apply
Miller's law into your work figure out
ways to categorize and then
sub-categorize objects or items inside
of your design and if you need to figure
out how to sub subcategorize last little
tip you don't have to use the magical
number of seven if you have less options
go with less that's better don't fill it
out with a bunch of Superfluous content
just because you want to hit seven
challenge yourself to have as little as
possible on the page to make the user's
experience as good as it possibly can be
well that's it those are the four most
important laws of ux design some of you
out there might be saying well what
about this what or what about that one
you missed like I said earlier in the
video there are tons of laws and
principles and best practices in the ux
design these just happen to be the four
I find to be most important this video
was inspired by the website laws of ux
I'm gonna put the link down in the
description where you can explore these
four C examples implementations as well
as tons of other principles best
practices and ux laws so check that out
if you want to learn more I hope you
enjoyed the video if you did make sure
you leave a thumbs up subscribe the
channel and ring that Bell so you know
when more videos like this one come out
I hope you're having an amazing week I
hope you're designing amazing things
making amazing things and using these
laws of ux to make your designs even
better I'll see in the next one
