Choosing Styles and Aspect Ratios is a free AI for Everyone lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the AI for Everyone learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

Steering the Look

Beyond what is in your image, you control two big levers: the style (photo, cartoon, watercolor) and the aspect ratio (the shape of the image).

These two choices dramatically change how your picture feels and where it fits. Mastering them lets you steer the look with confidence.

Style Changes Everything

The same subject looks completely different across styles. A "mountain lake" can be a crisp photo, a soft watercolor, or a playful cartoon.

Style sets the entire vibe. Before generating, decide: do I want this to look real, artistic, or fun? That single word reshapes the whole image.

Popular Styles to Try

Here are styles worth knowing:

  • Photorealistic — looks like a real photo.
  • Cartoon / illustration — drawn and playful.
  • Watercolor / oil painting — soft and artistic.
  • 3D render — glossy and modern.
  • Minimalist / flat — clean and simple.

Try several on the same idea to feel the difference.

Match Style to Purpose

The right style depends on the job. A business flyer might want clean and minimalist; a child birthday card wants bright cartoon; a product mockup wants photorealistic.

Ask yourself who will see this and where. Letting the purpose guide the style ensures your image fits its real-world home instead of clashing with it.

What Aspect Ratio Means

Aspect ratio is just the shape of the image — its width compared to its height.

  • Square (1:1) — Instagram posts.
  • Portrait (tall) — phone screens, stories.
  • Landscape (wide) — banners, presentations.

Picking the right shape from the start saves you from awkward cropping later.

Pick the Shape for the Place

Always match the ratio to where the image will live. A wide landscape image squeezed into a square Instagram post gets ugly black bars or chopped edges.

Think first: "Where am I posting this?" Then choose the shape that fits naturally. This tiny bit of planning makes your images look professional and intentional.

Common Ratios at a Glance

A handy reference:

  • Social post: square (1:1).
  • Phone story: tall portrait (9:16).
  • Website banner: wide landscape (16:9).
  • Print photo: classic 3:2 or 4:3.

Most tools let you pick these with a simple click or a word in your prompt.

Combine Both Choices

The real power is mixing them. "A photorealistic city skyline, wide landscape" or "a cute cartoon cake, square format" — you set both the look and the shape together.

When style and ratio both match your purpose, the image drops perfectly into place wherever you need it. That combination is what makes results feel finished.

Stay Consistent for a Set

Making several images for one project? Keep the style consistent so they look like a family.

Reuse the same style words across all of them — "all in flat minimalist style." Consistency makes a collection feel intentional and professional, whether it is a slide deck or a social campaign.

Experiment Freely

Because generating is fast and often free, experiment! Try the same idea in three styles and two ratios, then pick the winner.

You learn what works by playing. Over a few sessions, you will build a personal sense of which styles and shapes you reach for again and again.

You Are the Art Director

With style and aspect ratio in your toolkit, you are directing the image like a designer would.

You decide the look and the shape, and the AI executes. That control transforms you from someone hoping for a good result into someone confidently crafting exactly what they need.

Quick Check

Pick the right shape.

Recap

Two levers steer the look: style (photo, cartoon, watercolor, 3D, minimalist) and aspect ratio (square, portrait, landscape).

Match the style to your purpose and the shape to where the image will live. Combine both for a finished result, keep them consistent across a set, and experiment freely. You are the art director now.
