What are the laws of ux?
The laws of ux are simple rules based on how our brains work. They explain how people scan, choose, and remember. Designers use these rules to make clear pages and smooth flows. They help you pick the right layout, buttons, and words so users act with ease.
Where did they come from? Many come from psychology. Some focus on choice, speed, memory, and habit. When you follow the laws of ux, you build with how people think, not against it.
Where do the laws of ux fit? They fit in your design system and your product roadmap. Use them when you create new pages. Use them when you improve forms or onboarding. Add them to team playbooks. If you are learning, programs like General Assembly Bootcamp, Designlab UX Academy, Interaction Design Foundation, or a UX Design Degree can help you master the basics. Paths like springboard ux bootcamp or an ux research certification can deepen your skills too.
How laws of ux drive conversions
The laws of ux drive conversions by shaping what people notice and what they do next. Good UX guides attention. It helps people decide faster. It reduces errors. It calms fear and builds trust. That means more clicks on the right buttons and fewer drop-offs.
- Attention shaping: Clear contrast and grouping pull the eye to your main action.
- Decision speed: Fewer choices and simple steps mean quicker yes decisions.
- Error reduction: Helpful hints and instant feedback prevent mistakes.
These wins show up in core CRO metrics:
- CTR (click-through rate): More people click your key CTA.
- CVR (conversion rate): More users finish the task, like a signup or checkout.
- AOV (average order value): Clear options and smart defaults raise cart value.
- LTV (lifetime value): Happy users return, spend more, and refer friends.
Use laws of ux to link UX work to goals the business cares about. Share before-and-after tests. Run usability testing with real users. Use ux testing tools and ux research tools to find problems and track gains.
10 laws of ux patterns that convert
1) Hick’s Law: Fewer choices, faster decisions
Why it converts
When people see many choices, they slow down. Hick’s Law says fewer, clearer options help users decide faster. This law is a core part of the laws of ux because it trims noise and points to the next step.
Best-fit UI patterns
- Progressive disclosure (show more only when needed)
- Grouped menus with clear labels
- Staged forms with one task per step
Example use cases
- Pricing tables with 3 clear plans and one marked “Most popular”
- Navigation menus that group links by task
- Onboarding that asks one simple question at a time
Metrics to watch
- Time to first action
- Form completion rate
- Drop-off by step
Quick checklist
- Can a new user pick a path in under 3 seconds?
- Do you show only what the user needs now?
- Do you make one choice look like the best start?
2) Fitts’s Law: Make targets easy to hit
Why it converts
Fitts’s Law says big, close targets are faster to tap. This part of the laws of ux boosts clicks on your main CTA and lowers mistakes, especially on mobile.
Patterns
- Primary button with strong contrast and large size
- Tap-friendly spacing so fingers do not hit the wrong item
- Sticky CTAs that stay in reach
Use cases
- Checkout CTAs that stay fixed at the bottom on mobile
- Mobile nav with large, clear labels
- Thumb zones that keep key actions where thumbs rest
Metrics to watch
- Mis-taps or rage clicks
- CTA CTR
- Mobile bounce rate
Quick checklist
- Is the main CTA the biggest, clearest target?
- Is there enough space between links?
- Can a thumb reach the key action on small phones?
3) Jakob’s Law: Design for familiarity
Why it converts
Jakob’s Law says users spend most time on other sites. They expect your site to work the same. This law of the laws of ux builds trust fast. People act faster when things feel familiar.
Patterns
- Conventional layout (logo top left, nav top, search clearly visible)
- Standard iconography (magnifying glass for search, heart for save)
- Predictable flows (cart, checkout, confirm)
Use cases
- Search bars where users expect them
- Filters on the left or top with standard labels
- Pagination with clear next and previous
Metrics to watch
- Task success rate
- Help requests or chat pings
- Session length and repeat visits
Quick checklist
- Are you copying best-loved patterns from top apps?
- Did you keep labels plain and common?
- Did you resist clever but confusing layouts?
4) Law of Proximity: Group related items
Why it converts
This law in the laws of ux says items close together feel related. Good grouping helps users scan faster and make sense of content, which raises clicks and lowers errors.
Patterns

Use cases
- Feature lists grouped by benefit
- Filter panels grouped by type

- Do sections have clear titles and whitespace?
- Is each group easy to scan in one glance?
5) Miller’s Law: Keep it in working memory
Why it converts
People can hold only a few things in their mind at once. This part of the laws of ux says we should reduce mental load. Small steps and helpful hints keep users moving.

- Is your main CTA at a high-impact position?
- Are low-value links tucked in the middle?
8) Von Restorff Effect: Make the key action stand out
Why it converts
Also called the isolation effect, this law in the laws of ux says standout items get noticed and remembered. Make your main action look different.

- Do you show a skeleton or progress for longer tasks?
- Is slow code or heavy media trimmed?
10) Zeigarnik Effect: Nudge to finish what’s started
Why it converts

FAQs about laws of ux for conversion
Do laws of ux apply to B2B and enterprise products?
Yes. People are people. Clear choices, fast feedback, and familiar patterns help busy teams finish tasks with fewer errors. The laws of ux work across all product types.
How many laws should I prioritize for a new funnel?
Start with three: Hick’s Law for choice, Fitts’s Law for tap targets, and the Von Restorff effect for standout CTAs. Add others once you see results.
What metrics best capture the impact of these patterns?
Track CTR, CVR, time to first action, error rate, and drop-off by step. Link tests to revenue or signups to show value.
How do I balance brand creativity with familiarity?
Be bold in visuals but familiar in structure. Use Jakob’s Law to keep layout and flows standard. Use color, imagery, and voice to show brand.
