Claude 101(8) — Design Posters, Social Posts and Visuals With Claude Design
In this guide, you will learn how to use Claude Design to create polished posters, Instagram posts, birthday cards, event invites, and infographics — without ever opening Photoshop, Canva, or Figma.
Required Tools: Claude Pro

Overview
Most people don't need a designer for everyday visuals — they need a poster for the weekend market, an Instagram graphic for a small business launch, a birthday card for a parent, or a flyer for a class. Claude Design generates ready-to-use visuals from a plain-English description, then lets you refine them by talking, not by clicking. In this guide, we'll walk through the prompt formula that produces good designs on the first try, build a real poster step by step, and copy-paste-ready prompts for the 5 visuals normal people actually need.
Who This Is Useful For
What You Will Build
A real poster (we'll use a "weekend market" example) generated from one prompt and refined through 3 iterations. By the end, you'll have a downloadable image you can post on Instagram, print, or send via LINE.
You'll also walk away with reusable prompt templates for:
What You Need
Step 1: Understand What Claude Design Actually Does
A normal Claude image asks for an illustration. Claude Design is different — it generates layout-aware visuals built around your text content:
Think of it as the gap between "asking AI to draw a picture" and "designing in Canva". You describe what you want; Claude lays it out.
Step 2: The Design Prompt Formula
Here's the structure that produces a usable design on the first try:
Design a [type of visual] for [purpose].Dimensions: [size or platform]
Content (use exactly this text):
Title: [your title]
Subtitle / details: [your details]
Date / time / location: [if applicable]
Call to action: [if applicable] Style:
Vibe: [warm / professional / playful / minimal / bold]
Colors: [colors you want, or "use your judgment"]
Avoid: [things you don't want, e.g. "no clip art", "no stock photos"] Output as: PNG, ready to share on [platform]
The five sections — type / dimensions / content / style / output — give Claude everything it needs. Skip any section and Claude will guess; fill them in and you'll get exactly what you pictured.
Step 3: Build Your First Poster
Let's design a real poster — for a "Weekend Maker's Market" pop-up. Open a new chat and paste:
Design a poster for a community weekend market.Dimensions: A3 portrait (suitable for printing and Instagram story crop)
Content (use exactly this text):
Title: Weekend Maker's Market
Subtitle: 30+ local artists, food, live music
Date: Saturday, May 30 · 10am – 6pm
Location: Da'an Park, Taipei
Call to action: Free entry · @weekendmarket Style:
Vibe: warm, hand-crafted, slightly retro
Colors: cream background, terracotta and sage green accents
Typography: bold headline, clean body text
Avoid: stock photos, generic clip art, anything corporate Output as: PNG, high-res, ready to print and post on Instagram
Claude Design will think for 20 to 40 seconds, then return your poster in the side panel. You'll see a download button and an "iterate" button.
Step 4: Iterate by Talking to It
The first version will be 80% there. Here's how to push it to 100% — using plain English, not design jargon:
Each request updates the design. You'll see a new version side-by-side with the old one. Claude will tell you what changed and why.
Step 5: Five Ready-to-Use Templates
Copy any of these prompts, swap in your own details, and run them in Claude Design.
Instagram square post (event announcement):
Design a square Instagram post (1080×1080) announcing [event].Content:

Each tip in its own visual block.
Use a calm color palette — no bright reds.
Product launch announcement:
Design a product launch graphic, square (1080×1080), for Instagram and LINE.Content:
Headline: "Now Available"
Product name: [name]
1-line tagline: [tagline]
Price: [price]
Where to buy: [link or location] Style: bold, confident, premium.
Single product on a clean background.
Use [your brand color] as the accent.
Step 6: Export and Use
When the design is final, click Download in the Artifact panel. You can choose:
Files save to your computer's Downloads folder. From there, post to Instagram, send via LINE, print at 7-Eleven, attach to email — wherever you need it.
Going Further
Build a brand kit. Tell Claude once: "My brand colors are #2A4D3F and #F4E6D7. My fonts are Inter for body and Playfair for headlines. My logo is attached." Save this as a Project. Now every design starts on-brand automatically.
Generate a series. Need 7 daily Instagram posts? Ask Claude to "generate 7 variations of this design with these 7 different headlines, keeping the same style and layout". You get a consistent series in one prompt.
Hand off to a real designer when needed. Claude Design is great for 90% of small-business needs. When you do need a real designer (logo redesign, complex packaging), use Claude to create the brief — describe the mood, attach 3 reference images, and let the designer take it from there.
Key Takeaways
Here's what you learned in this guide:
Within a few days, you'll stop opening Canva for small jobs entirely. The combination of speed (30 seconds vs 30 minutes), iteration (talk vs click), and quality (no template-y look) is hard to go back from.
