aka How to Stop Guessing and Actually Make Things Look Good

Let’s Be Honest For a Second…

Ever looked at someone else’s design and thought, “WHY does this look so good and mine looks like a PowerPoint from 2009?”

Don’t worry. You’re not broken. You’re just missing some of the core design principles. And no, they’re not as scary or elitist as they sound. You don’t need to go to art school or speak in fonts to get this stuff. You just need to understand the why behind what makes things look and feel good.

And before you ask—yes, AI can help. But AI without taste is like giving a five-year-old a paintball gun. You might hit the target. You also might end up with chaos and glitter everywhere.

So let’s fix that. Let’s learn the actual principles behind good design—laid-back, real-world style. Ready?

🎯 Why Design Principles Even Matter

Imagine trying to cook without understanding flavors. You’d just throw stuff in a pan and pray, right?

Same with design.

These four principles—Layout, Color, Typography, and Composition—are the ingredients. You can wing it sometimes, but if you want to consistently make things that pop, you’ve gotta know what you’re working with.

1. ✏️ Layout: Where Stuff Lives on the Page

“Where should I even put this??” – every beginner designer ever.

Layout is all about structure. It’s how you place your elements—text, images, buttons, white space—so they actually make sense to the viewer. Because if your layout feels messy, people bounce.

Real-Talk Tips:

• Use a grid. Even a loose one. Canva and Figma have guides for a reason. Eyeballing works… until it doesn’t.
• Hierarchy matters. Your title should be bigger than your body text. Buttons should stand out. Don’t whisper important things.
• Whitespace isn’t “wasted space”. It’s like air in a song—you need it. Cramming too much into one section? Visual anxiety, my friend.

Banter Break:

You ever see a flyer with 18 fonts, 6 photos, and a rainbow background? Yeah, that’s what happens when layout has a panic attack. Don’t be that flyer.

2. 🎨 Color: Not Just About “Looking Pretty”

Okay, color gets a lot of attention. Rightfully so—it’s emotional, it’s expressive, it sets the vibe.

But also? It can destroy your design faster than you can say “neon-on-neon crime scene.”

Real-Talk Tips:

• Start with 2-3 colors, max. A primary, a secondary, and maybe a third for pop. Don’t go full unicorn on your first day.
• Use color psychology. Blues = trustworthy. Reds = urgent. Yellows = friendly. (Also: trust your gut—your brain feels color before it understands it.)
• Contrast is king. Light text on a light background? Oof. Use dark/light combos that are actually legible.

Quick Fix:

Use tools like Coolors or Khroma to generate palettes. Or use AI to create brand-based ones. Ask:

“Can you create a color palette for a peaceful yoga brand targeting Gen Z women?”

Watch the magic unfold.

Anecdote Time:

I once worked with a new designer who insisted on using pastel yellow text on white because it was “soft and elegant.” I love her—but I also had to squint so hard I thought I needed new glasses. Moral? Pretty doesn’t always mean practical.

3. 🔠 Typography: Fonts Have Feelings Too

Fonts are low-key emotional manipulators.

A font can say “I’m fun and casual” or “I will sue you.” And picking the wrong one is like wearing Crocs to a black-tie wedding. Comfy? Sure. But just… no.

Real-Talk Tips:

• Stick to two fonts: one for headings, one for body. Three if you’re feeling really bold.
• Match the vibe: A lawyer’s site shouldn’t use Comic Sans. A kid’s birthday invite probably shouldn’t use Times New Roman.
• Line spacing matters: Give your text room to breathe. Tight lines = reading fatigue.

Slangy Sidebar:

You ever see one of those “inspirational quote” posts in cursive that’s so curly you need a decoder ring? Fonts should communicate, not confuse.

4. 🎯 Composition: The Vibe Check

This one’s kinda the umbrella over everything. Composition is how all the pieces—layout, color, type, images—come together to create a feeling.

It’s the difference between a messy desk and a clean workspace. One screams “chaos,” the other whispers “clarity.”

Real-Talk Tips:

• Balance your elements. If the left side is heavy, lighten the right. Imagine your design on a seesaw.
• Alignment matters. Things should line up—visually and emotionally.
• Focus the eye. Use focal points (big text, bold color, imagery) to guide attention like a trail of breadcrumbs.

Subjective Truth:

Sometimes, composition is more felt than calculated. You’ll just know when it looks right. Like how a song just flows. Trust that instinct. It gets louder the more you practice.

🧠 What AI Can—and Can’t—Do With These Principles

Alright. You might be thinking, “Cool, but can’t AI just do all this for me?”

Sort of. But not really.

AI can generate layouts, pick fonts, even build entire websites. But it can’t:

• Read a client’s micro-expression when they hate the vibe.
• Feel when a design looks “off” even if it’s technically “right.”
• Choose the exact blue that feels trustworthy but also modern.
• Inject your personality into the visual tone.

That’s on you. The human. The vibe-checker. The storyteller.

Pro Move:

Use AI as your intern. Ask for starting points. Generate options. But you be the creative director.

Example Prompt:
“Hey ChatGPT, give me 3 layout ideas for an eco-friendly skincare landing page with Gen Z in mind.”

Then you tweak, refine, and inject your you-ness.

🫶 Tiny Pep Talk Before You Bounce

Design is one part rules, one part rebellion.

These principles? They’re your map. But YOU are the explorer. Sometimes, you follow the path. Sometimes, you cut your own.

You will make clunky designs. You will look back at old stuff and cringe. That’s growth. That’s real.

Every great designer was once a beginner Googling “what even is kerning.”

So don’t overthink. Start creating. Play with layouts, swap fonts, mess up a palette and learn why it didn’t work.

This is where it starts.

🧰 Bonus Toolkit (Just for You)

If you’re hungry for more, here’s a quick starter pack:

• Canva – Great for layouts, tons of templates.
• Figma – For the UI/UX curious.
• Fontpair.co – Helps you match fonts like a pro.

TL;DR (But Still Kinda Important)

• Layout = Where stuff goes.
• Color = How it feels.
• Typography = What it says and how.
• Composition = The full emotional effect.

Master the basics. Break the rules later.

And always—always—trust your weird, creative, human brain.

You got this. 🎨💻🔥
