No, the Uncertainty Principle puts a lower limit on the product of position and momentum certainty. So that limit (which I think is hbar/2) determines when the Uncertainty Principle becomes relevant. And it turns out, it doesn't really apply until you get down to individual electrons. Whole atoms can be pinned down quite accurately with respect to their size.
