The model can be scaled to the size you want to print. You will find multiple files, the first is the plain one with no background, while the second has a back border for pasting a background so you can insert the unattached parts of the wall art. The background is printed separately, printed in the color you want, always scaled by the size of the wall art and pasted behind.
The model with the border I printed upside down on a Textured plate to leave a nice finish in front, the part of the border remains behind and allows you to glue the background.
