Photoshop/ Stick Art/ Printing?


Hello everyone, just wondering how I would get this printed.

I used the DC Agetec template found here and applied an image I liked to it, check it out:

Now my question is how do I get this printed to scale? Is the template file already to scale, when I take it somewhere to get printed will it be to the correct scale?

Sorry im a total noob to photoshop and printing stick art.
