MidJourney Aspect Ratios: How to Optimize Images for Instagram, Facebook, Twitter, and LinkedIn

I’ve been spending some serious time exploring MidJourney’s capabilities—and I just learned something that completely leveled up how I approach blog visuals: aspect ratio optimization for different platforms. It makes your image perfectly tailored for Instagram, Facebook, Twitter, and LinkedIn.

In this post, I’ll share what I’ve discovered about customizing aspect ratios using MidJourney, so your images not only look good—but look perfect everywhere they’re posted. 

Why Optimization Matters 

You’ve created stunning images, but when you post them… something’s off. Maybe the crop is awkward, or the resolution feels fuzzy. That’s because each platform has its own image specs—dimensions, file sizes, and aspect ratios—that affect how your content is displayed.

Let’s break it down by platform:

 Instagram

Instagram is all about aesthetics. Here’s what you need to know:

• Profile Picture: 320 x 320 pixels → Aspect Ratio 1:1

• Post Image:

  • Portrait: 1080 x 1350 → 4:5

  • Square: 1080 x 1080 → 1:1

  • Landscape: 1080 x 566 → 1.91:1

• Story Image: 1080 x 1920 → 9:16

Sample MidJourney prompt: /imagine inspirational quote Stories for Instagram in modern style and vibrant colors --ar 9:16




 Facebook

Facebook supports a variety of formats. Here’s the cheat sheet:

• Profile Picture: 170 x 170 → 1:1

• Cover Photo: 820 x 312 → 41:26

• Shared Image: 1200 x 630 → 12:6.3

Sample MidJourney prompt: /imagine cute puppy --ar 12:6




 Twitter

Twitter is fast-paced, and your visuals need to keep up:

• Profile Picture: 400 x 400 → 1:1

• Header Photo: 1500 x 500 → 3:1

• In-Stream Photo: 1024 x 512 → 2:1

Sample MidJourney prompt: /imagine header photo for Twitter with black background and puppies --ar 3:1

 LinkedIn

Professional, polished, and precise—LinkedIn demands clean visuals:

• Profile Picture: 400 x 400 → 1:1

• Background Photo: 1584 x 396 → 4:1

• Shared Image: 1200 x 627 → 2:1

Sample MidJourney prompt: /imagine LinkedIn background photo in red and pink with text : MidJourney Pro --ar 4:1




Crafting the Perfect Prompt 

So, to optimize images for different platforms, use the –ar (or –aspect) parameter to change the aspect ratio of the generated image. It is typically expressed as two numbers separated by a colon, such as 7:4 or 4:3.

To find the aspect ratio, divide the width (1500) by the height (500) and simplify the fraction. The correct aspect ratio of a Twitter Header Photo is 3:1.

Once you know the aspect ratio you need, it’s all about combining the right format + content + style in your prompt.

Be as clear as possible about:

• Platform
• Purpose (post, header, story, etc.)
• Visual theme (colors, layout, mood)
• Text (if any)

Quick Reference: Aspect Ratios by Platform

Platform	Use	Dimensions (px)	Aspect Ratio
Instagram	Story	1080 × 1920	9:16
Facebook	Shared Image	1200 × 630	12:6.3
Twitter	Header Photo	1500 × 500	3:1
LinkedIn	Background Photo	1584 × 396	4:1

How to Create Stunning Blog Illustrations Using MidJourney Text Prompts

Lately, I’ve been diving deep into MidJourney, and I recently uncovered a technique that completely changed the way I approach visual content—creating blog illustrations using text prompts.

In this post, I’ll share what I’ve learned about using MidJourney to generate powerful, custom illustrations that include your own text—perfect for blog headers, quotes, infographics, and more.

Whether you’re a blogger, content creator, or just curious about AI tools for storytelling, this is something you’ll want to explore.

The Power of Visual Storytelling

Visuals are more than just eye candy. They can:

• Reinforce your message

• Simplify complex topics

• Guide your readers through the content

• Keep engagement high from top to bottom

MidJourney makes it easy to take this a step further by letting you add text directly into your illustrations—tailored exactly to your post’s tone and theme.

Starting with the Text

Before crafting a prompt, decide what message you want to integrate. That could be:

• A catchy quote

• A blog section header

• A motivational phrase

• A post title or summary highlight

Example starter prompt:
/imagine motivational illustration for blog header with the text: "Start Your Day with a Smile!"

Crafting the Perfect Prompt

The key to great results in MidJourney is being specific.

Consider:

• Mood: cheerful, calming, professional, minimalist

• Color palette: bright, muted, pastel, earthy

• Style: hand-drawn, digital, realistic, flat design

• Elements: characters, icons, nature, textures

For example:
/imagine motivational illustration for blog header using bright colors, cheerful characters, and a sunny background with the text: "Start Your Day with a Smile!"

Match the Visual to the Blog Topic

This was one of my favorite discoveries—contextual illustrations really improve how a post feels. When visuals echo the topic, it adds clarity and relevance.

Example for a fitness-related post:
/imagine a health and wellness illustration for fitness with integrated text: "Stay Active, Stay Healthy!"

Tailor to Blog Sections

Different sections of a blog benefit from different visual styles.

For example:

• Tips sections = icons, clarity, clean layout

• Inspiration sections = quotes, colors, emotion

• Tutorials = diagrams, steps, structure

Prompt for an educational tips section:
/imagine educational illustration for the tips section of a blog using icons, simple graphics, and clean layout with the text: "Top 5 Productivity Hacks"

Boosting Blog Engagement with Visual Summaries

Want to help readers remember the key ideas and keep them scrolling? Try creating summary visuals at the end of your posts.

These work great for:

• Key takeaways

• Final reminders

• Shareable summaries

Prompt example:
/imagine an engaging illustration for a blog post summary to boost engagement with the text: "Key Takeaways"

Final Thoughts

I’ve only just started using MidJourney this way, but honestly—it’s been a creative breakthrough.

In this post, I’ve shared what I’ve learned about turning blog messages into dynamic visuals using carefully written text prompts. The flexibility, speed, and visual quality are truly impressive.

Every blog post is an opportunity to visually connect with your audience. With tools like MidJourney, you can turn words into images that stick.

I’ll be experimenting with more styles and use cases soon, and I’ll keep sharing what I learn along the way.

AI Pattern Design with MidJourney: Packaging & Fabric Made Easy

I’ve been exploring MidJourney for a while now—playing with lighting, blend modes, and composition has been a blast. But recently, I uncovered a whole new layer to its creative potential: pattern design.  From packaging visuals to custom fabrics, it turns out MidJourney isn’t just for striking portraits or atmospheric scenes—it’s also a powerful tool for creating patterns that truly stand out. Whether you're building a brand or sketching for fashion, learning how to generate and apply unique patterns is the next big skill in the creative toolkit.

In this post, I'll share what I've learned about creating, visualizing, and marketing unique patterns using Midjourney. If you’ve ever dreamed of seeing your designs on real products, this is your sign to start. Let’s jump into this exciting creative journey together!

Why Pattern Design Matters

Pattern design is the art of creating repeatable visual elements that enhance anything from product boxes to clothing textiles. Think florals for cosmetics, geometric prints for streetwear, or abstract themes that scream creativity. At its core, it’s about making designs that are visually compelling and consistent across surfaces.

 Designing for Packaging

Start with a clear theme that mirrors your brand or product vibe. Do you want soft elegance, bold statements, or playful charm? Here’s a sample MidJourney prompt to get rolling:

/imagine Create a floral pattern for cosmetic product packaging  

MidJourney’s AI will surprise you with how nuanced and brand-ready these visuals can be.

 Designing for Fabrics

Now let's bring it to textiles. Choose a style—geometric, abstract, or thematic—that suits the fashion identity you're crafting. Try something like:

/imagine Create a geometric pattern for fashion fabric  

You’ll see designs that could easily walk off a runway or brighten up a boutique shelf.

 Applying Patterns to Products

Don’t stop at just designing—visualize them on actual products. Mockups give your creations context and commercial flair. Here’s a pattern application prompt:

/imagine Apply the floral pattern to a cosmetic product mockup  

Seeing your pattern in action elevates it from concept to tangible product.

 Marketing Your Creations

Presentation is everything. Use sleek mockups to showcase your patterns on social platforms, portfolio sites, or marketplaces like Etsy or Creative Market. Authentic storytelling around your designs can make all the difference.

 Practice Makes Perfect

Keep experimenting. One great way to get familiar with the process is to mix pattern generation with product placement:

/imagine a floral pattern in pink colors on a sneakers mockup  

It’s fun, and the outcomes are often surprisingly unique.

 Wrapping It All Up

MidJourney isn't just a creative tool—it’s a design partner. Now that you've learned the basics of creating and applying patterns, you're ready to transform your ideas into marketable designs.
