The 3x3x10 System: How to Brainstorm 90 Instagram Content Ideas in 5 Minutes

We’ve all been there: Staring at your content calendar, trying to come up with post ideas, and ending up scrolling Instagram instead.

You want to stay consistent, but brainstorming content every week just takes forever.

What if I told you there’s a super simple system that helps you come up with 90 content ideas in just 5 (!) minutes?

Yep. That’s exactly what I’m going to show you in this post.

It’s the same system I use inside the Template Membership to plan new content packs each month, and it works for any business.

Let’s break it down step by step 👇

Step 1: Start With Your Product (Not Random Topics)

This is where most people go wrong.

They start with “motivational quotes,” “tips,” or “behind the scenes” and end up posting things that don’t actually sell their product.

You need to flip it.

Start with your product — the thing you want people to buy — and build your content ideas around it.

Ask yourself:

  • What problem does my product solve?
  • What transformation does it help create?
  • What do people need to believe or understand before they buy it?

That’s your starting point.

Let’s say you sell:

  • A planner → Your content should revolve around planning, time management, and staying organized.
  • A digital course → Focus on the transformation and small wins your students experience.
  • A Canva template membership 😉 → Your content should show how templates save time, help you show up consistently, and make your brand look amazing.

So instead of “What should I post?” you start with “What do people need to know, feel, or see about my product?”

Step 2: Choose Your 3 Main Pillars

Once you’ve anchored your product, choose 3 pillars that support it.

These are the core themes your audience needs to hear about again and again to connect with your offer.

For example, if your business is all about helping entrepreneurs with content creation, your pillars could be:

  1. Content Creation & Design – show how to create high-quality, scroll-stopping content.
  2. Content Strategy & Planning – help them stay consistent and organized.
  3. Business Growth & Confidence – show the bigger picture of what good content can do.

Each pillar leads back to your product, but from a slightly different angle — education, inspiration, or results (sociall proof).

Step 3: Add 3 Topics Under Each Pillar

Now it’s time to go a level deeper.

Under each pillar, choose 3 specific topics you can talk about repeatedly.

Here’s an example:

Pillar 1: Content Creation & Design

  • Design tips & tricks
  • Canva hacks
  • Visual consistency & branding

Pillar 2: Content Strategy & Planning

  • Content pillars & ideas
  • Batching & workflow tips
  • How to create content that sells

Pillar 3: Business Growth & Confidence

  • Time-saving & productivity
  • Showing up confidently online
  • Results & success stories

Already, you’ve got 9 clear topics, which are all directly tied to your product’s benefits.

Step 4: Use 10 Prompts for Each Topic

Now comes the fun part.

Apply the same 10 content prompts to each topic to instantly generate 90 ideas.

Here are your prompts:

  1. Quick tip
  2. Common mistake (and how to fix it)
  3. Before/after or transformation
  4. Mini tutorial (3–5 steps)
  5. Checklist
  6. Myth vs. fact
  7. Template or swipe post
  8. Q&A (answer a real question)
  9. Behind the scenes
  10. CTA or reminder post

Or come up with your own prompts, or things that are trending or relevant in your niche right now.

That’s it.

3 pillars × 3 topics × 10 prompts = 90 content ideas.

Step 5: See It in Action

Let’s say your product is the Template Membership (or any product that saves people time with content).

Take the topic “Batching & Workflow Tips.”

Here’s what it looks like with the prompts:

  1. Quick tip → “Batch your captions before designing — saves 40% of your time.”
  2. Mistake → “Batching fails when you open Canva too early — plan first.”
  3. Before/after → “Here’s my content workflow before templates vs. after.”
  4. Tutorial → “How I plan 30 posts in 2 hours using Canva templates.”
  5. Checklist → “6 things I prep before opening Canva.”
  6. Myth → “Myth: batching kills creativity. Fact: it frees it.”
  7. Template → “Here’s the template I use to plan my weekly content.”
  8. Q&A → “How many posts should I batch at once?”
  9. Behind the scenes → “Here’s how I organize my content folders in Canva.”
  10. CTA → “Want these templates ready to go? They’re inside the membership.”

That’s one topic, and 10 ideas.

Multiply by 9 topics, and you’ve got a full 90 days of content ideas.

Step 6: Turn your Ideas into Instagram Posts

Most people stop at “brainstorming ideas.”

But ideas don’t grow your business. Executing them does.

That’s where templates come in.

Inside the Template Membership, we take this exact system and make it visual for you.

For each of those 10 prompts (and more!) we have sets of matching Canva templates: Tip posts, checklist designs, carousel layouts, tutorials, testimonials, and more (all done-for-you).

So when you’ve brainstormed your 90 ideas, you don’t have to design 90 posts from scratch.

You just open your Canva folder, choose a template, plug in your idea, and you’re ready to post.

Why This System Works So Well

It forces you to stay focused on what actually sells your product. Not random content trends or viral audios.

When every post is connected to your product, you start to:

✅ Build stronger brand recognition

✅ Attract the right followers who actually buy

✅ Create content faster, without the burnout

And once you’ve built your 3×3×10 matrix, it becomes your go-to system every month.

Ready to Try It?

If you want to try this for your own business, sit down for 10 minutes today:

  • Write down your product
  • Define your 3 pillars and 3 topics
  • Apply the 10 prompts to each

Boom — you’ve got your 90 content ideas.

And if you want to skip straight to the done-for-you part… with 3,500+ matching Canva templates and monthly content calendars already built around this exact system, you’ll love the Template Membership.

It’s your content strategy + visuals + consistency all in one place.
