How to sell custom T-shirts on Etsy

Selling custom t-shirts on Etsy is one of the easiest ways to start a print-on-demand (POD) business today especially if you’re looking for something low-risk, creative, and scalable.

The best part is that you don’t need to hold inventory, know how to design professionally, or spend thousands upfront. With the right tools, like Printify and Listadum, you can research what’s trending, create your own shirt designs, and start selling in just a few hours.

Here’s a beginner-friendly guide to help you get started.

Why Etsy focuses on Custom and personalized products?

Etsy stated in their Annual Report that they are trying to establish themselves not as a marketplace but as the best gift shop, or we can say the best gift marketplace, where people solely go to buy gifts. And what gives more gift options than custom and personalized products?

T-shirts are the top-selling custom products on Etsy because, first, they are a very easy and impressionable product. You don’t need to put in extra effort if you have the right T-shirt with the right quote on it for the occasion. That’s why you can find a vast variety of T-shirts on Etsy, from emotional messages and funny drawings to inside jokes.

Why sell custom T-Shirts on Etsy?

Custom t-shirts are one of the best-selling categories on Etsy. Whether it’s funny slogans, retro designs, or niche themes like “math teacher gifts,” buyers are actively searching for shirts that feel personal and relatable.

Here’s why t-shirts work so well:

• Low cost to create (no inventory)
• High demand year-round
• Endless niches to explore (pets, professions, hobbies, quotes)
• Easy to scale your design to mugs, sweatshirts, totes, and more

If you want to build a store with consistent sales, custom shirts are a smart place to start.

Step 1: Do product research right away

Before you start designing, research what people are already buying.

Here’s how to do that:

• Go to Etsy and search something broad like “teacher shirt”
• Notice the auto-suggestions (e.g. “math teacher shirt”, “funny science shirt”)
• Look at bestsellers with a high number of reviews and “in carts now” labels
• Use Listadum to dig deeper into monthly search volumes, competition, and trend scoresBig competition isn’t bad. It means there’s strong demand. Just look for micro-niches within it, like “retired math teacher shirt” or “funny algebra t-shirt.”

Step 2: Design your T-shirt even if you are not a designer

You don’t need Photoshop or a design degree. Tools like Canva and Creative Fabrica make it super easy to create high-quality designs.

Here’s how to create a simple, trend-friendly design:

1. Choose a retro-style font from Creative Fabrica (make sure it’s licensed)
2. Use Canva to write your phrase which is something niche and relatable like:“Show Your Work — Every Math Teacher Ever”
3. Add a few retro elements like smiley faces, flowers, or checkerboard patterns
4. Use Canva’s color picker to match the colors of trending products on Etsy
5. Save your design as a transparent PNG

Keep it simple. Bold fonts + clear message – easier for people to understand = better conversions

Step 3: Upload to Printify and pick the right shirt

Go to Printify, sign up for free, and choose a t-shirt base

Then:

• Upload your design
• Choose colors and sizes
• Pick a print provider with fast shipping, good reviews, and low base cost
• Save and sync to your Etsy shop

If you use Printify Premium, you’ll get discounts on every sale, which helps your profits.

Step 4: Optimize your Etsy listing

Your listing title, tags, and images are key to getting discovered.

• Title: Use high-search keywords like:
  “Funny Math Teacher Shirt, Retro Teacher Gift, Custom Back to School Tee”
• Tags: Add niche and long-tail keywords (e.g. “algebra shirt”, “high school teacher gift”)
• Photos: Use Printify mockups, but consider adding lifestyle mockups for a human touch

Use Listadum to track the top-performing tags and keywords so you can keep optimizing.

Selling t-shirts on Etsy is not about reinventing the wheel, it’s about finding smart angles, tapping into niches, and creating something visually appealing and relatable.

With tools like Listadum, Printify, and Canva, the barrier to entry has never been lower.

Start with one idea. Test it. And scale from there.
