I need to resize every single object within the wireframe; the template, masters, and loose objects on every page - there are hundreds of individual objects that need to be down-scaled due to my mistake.
I tried the way you suggested but if I CTRL-A everything and adjust the width, it changes the width of every single object to that variable instead of downsizing it.
For example; here is one of my masters which is about 1825 pixels wide.http://gyazo.com/a474b0f925f1a45d28212f1af1b9d00f
If I CTRL-A and change the width to 800 this happens.http://gyazo.com/140f32e4607aa32d5fe1b12be4d044fc
Some objects (those that had width <800px) actually grew in size.
