Aspect raito/scaling

I have been working on creating a new dash from scratch, creating it on my PC and wanting to use it on my tablet/phone but I can not figure out how to lock everything in position, after creating the dash on pc once moved to a device everything move and or is off-scale from how I had it.
Both free and paid dashes can do this is there something I am missing or is this a paid feature?

Its not a paid feature. If you design a dashboard on certain aspect, it must be scaled to other aspects in order to retain round objects as round.

ok thanks i did manage to find out what i did wrong, I had a odd size image so i just started again with a 1920x1080 background image
