Text exact alignment in a shape

Thank you for the reply.
I am using Printful at the moment so I'm just exporting my design using PNG then just banging them on their mock-up thingy.
Course I'm not at all happy with my designs mainly cause they don't look like they are the right size once they go on the mock-up.
Think practice makes perfect.
Ps what is the online company so I can download the template.
