Is there a way to scale your artboard and the content within at the same time?
Don't believe so, unless one uses scripting. (I'm not a propellerhead on that matter, though.) You could, of course, resize all the contents within an artboard at once by selecting them in the Layers panel.
Here's the best way I've found to do it.
With the content now scaled, you can either duplicate that Artboard back to the original document, or use it as its own new document.
Hope that helps!
There is no Image>Size option in Illustrator
Try this: Using the Image Size command on the entire doc scales all artboards and content to the new size. Figure out the new size as a percentage and you're good to go.
This worked perfectly for me, thank you!
Actually no sorry, it resizes everything but not to the size I set!
A hack for me is to create a recentangle shape that fills the entire artboard. Select all layers and scale down to your desired new artboard size - then align to top left corner. You can then manually adjust the artboard size to fit the same width / height dimensions.
If only there was just a checkbox in Photoshop 😉
