Obviously you would need to get the px dimensions from the front ent.  
I.e., in Javascript.

As far as the layout properties, a Block doesn't know anything about  
it's layout, that's the job of the Collection and Layout managers. You  
might be able to look up the block's details by grabbing the layout  
from Horde_Core_Block_Collection from within your block's code.  
Otherwise, I'd suggest using javascript to get the dimensions of a  
specific div (or other DOM element) inside your block's own DOM element.
