When using Printify to print T-shirts on demand using your own designs the recommended size of jpg /png files is 4606 px X 5787
I just wanted to add this info here as a quick reference because when I was making a design real quick from my phone on photoshp using custom canvas it ask for the Px and I didn’t remember it off the top of my head so I went to google doing a quick search for myself just for these numbers and I didn’t see it anywhere as just a quick reference without me having to go To my laptop and log back into my Shopify /Printify account just to find the numbers.
I hope this helps someone who is in the process of printing your shirts using Printify.
Happy Printing
