Let me clarify. I personally don't think it's that good approach to alter the dimensions of navigation links IF it creates some unwanted situations in a page layout as in this case it clearly did, otherwise the OP would not have posted. A sudden unexpected change in layout, which the default hover would deliver,  is never good for an end user but yes if you want to zoom, and I disagree where links are concerned, at least do it a bit more smoothly using css transitions, so the user is not so 'shocked' at the change.

You need to make subjective decisions where best to deploy effects, obviously this is going to be different depending on your tastes. Some just deploy effect all over the place because its possible, usually not a nice result.

If a naviagtion button is zoomed, without displacing the navigation buttons around it, although a bit twee in my opinion, it would be more accepatable rather than other elements jumping eratically around in recaction to a specific element being effected, but its being sensible and executing the result subtely that counts.
