name: design description: "10 Principles of Good Design - less but better"

Dieter Rams - Design Philosophy

Apply Dieter Rams' 10 Principles when making any design decision. These are non-negotiable quality gates.

The 10 Principles

1. Good design is innovative

• Don't copy existing patterns blindly
• Solve the actual problem, not the assumed one
• Technology enables new solutions - use it

2. Good design makes a product useful

• Every element must serve a purpose
• If it doesn't help the user accomplish their goal, remove it
• Useful > Beautiful (but both is best)

3. Good design is aesthetic

• Visual quality is not optional
• Ugly software signals careless thinking
• Well-executed details build trust

4. Good design makes a product understandable

• The interface should explain itself
• No manual required for basic operations
• Progressive disclosure for complexity

5. Good design is unobtrusive

• Tools should not demand attention
• The user's work is the focus, not the UI
• Neutral, restrained, leave room for user expression

6. Good design is honest

• Don't promise more than you deliver
• Don't manipulate users (dark patterns)
• Don't disguise what something is

7. Good design is long-lasting

• Avoid trendy for trendy's sake
• Classic over fashionable
• Will this look dated in 2 years?

8. Good design is thorough down to the last detail

• Nothing is arbitrary
• Every pixel, every spacing choice is intentional
• Consistency in the small things

9. Good design is environmentally friendly

• In software: performance is environmental
• Don't waste CPU cycles on animations nobody needs
• Respect bandwidth, battery, attention

10. Good design is as little design as possible

• Less, but better
• Remove until it breaks, then add back one thing
• Concentration on essential aspects

Prescriptive Rules

Color

- Maximum 3 colors in any interface
- 1 primary action color (use sparingly)
- 1 text color (with lighter variant for secondary)
- 1 background color (with subtle variant for cards/sections)
- Gray for everything else

Spacing

- Use a 4px base unit
- Spacing scale: 4, 8, 12, 16, 24, 32, 48, 64, 96
- Never use arbitrary values (no 13px, no 27px)
- Consistent spacing = professional appearance

Typography

- Maximum 2 font families (1 is better)
- Type scale: 12, 14, 16, 18, 20, 24, 30, 36, 48
- Line height: 1.5 for body, 1.2 for headings
- Never go below 14px for body text

Visual Weight

- One focal point per screen
- Hierarchy: Size > Color > Position > Style
- If everything is bold, nothing is bold
- White space is not wasted space

Review Checklist

Before shipping any UI:

• Can any element be removed without loss of function?
• Is there exactly ONE primary action visible?
• Does spacing follow the 4px grid?
• Are there 3 or fewer colors?
• Would this look good in 5 years?
• Is the design honest about what the product does?

Anti-Patterns

Bad	Why	Fix
Gradient buttons	Trendy, dates quickly	Solid color
Drop shadows everywhere	Visual noise	Use for elevation only
5+ colors	Chaotic, unprofessional	Reduce to 3
Random spacing	Looks unfinished	Use spacing scale
Decorative icons	Noise without meaning	Remove or make functional

Rams Score

Rate any design 0-10:

Score	Meaning
10	Nothing can be removed, everything earns its place
7-9	Minor excess, could be simpler
4-6	Significant clutter, redesign needed
0-3	Violates multiple principles, start over

Integration

This skill sets the philosophical foundation. Combine with:

• /usability - Psychology of how users perceive this design
• /components - Component structure that embodies these principles
• /charts - Data visualization aligned with "less but better"
