How To Design T-Shirts Using Canva - (Merch By Amazon, Redbubble & Printful)
About this video
He teaches designing t-shirts in Canva for Merch by Amazon, Redbubble, Printful, Etsy and similar platforms. He claims over $150k in all-time Merch by Amazon royalties. Step one, he says, is checking commercial-use rights and terms on any platform or media you use. Next, research before designing: check for demand and sales in a niche, look for a BSR on Amazon, and consider tools like Helium 10 for search volume, plus do trademark checks. He notes Canva’s free version, templates for inspiration, and a paid trial/subscription he quotes at $12.95. For Merch by Amazon he creates a custom design at 4500 by 5400, adds elements and text such as a ‘dog dad’ example, centers it for the chest, then downloads as a transparent-background PNG. Uploading to Amazon shows the first version is too small, so he enlarges it so phone shoppers scrolling thumbnails can actually see it.
Key takeaways
- Verify commercial-use rights and platform terms before using any graphics, fonts or illustrations in a design for sale.
- Research demand first — BSRs on Amazon’s front page and search-volume tools like Helium 10 — and check trademarks before designing.
- Use Canva’s t-shirt templates for inspiration, but set the custom Merch by Amazon size to 4500 x 5400.
- Download the finished design as a PNG with a transparent background.
- Make the design large enough to fill the shirt space so it is legible in small phone thumbnails while customers scroll.
