whatever the longest part of the image is the size that you select just think about that before you click the size please
I also put three photos one is what it actually looks like when it prints out and then I laid it on a black shirt so you could semi see it and we actually printed it so the last photo is showing it on a black shirt. I wouldn’t recommend it on another color shirt. You can do whatever you need, but it may not show up as well.
