Add a text dont scale

When I add a text in the custom product designer I get a box around the text. And the size of the box is the measure I get. So When people look at thier text its for example 90cm width and 28 height.
But when I download the file and open it to print it doesnt scale. 90cm width and only 16-18cm height.
So is there anyway I can scale down this “box” in designer mode so its closer to the textlines?
Now its offset up and down from the text couple of cm.
