In terms of physical dimensions, the orbit of the most outer planet (Neptune) is around 4.5 billion km from the sun, or 30 AU (Astronomical Units) where 1 AU is the earth to sun distance. So we are talking a 60 AU diameter orbit that all of the planets in our solar system fits into, a big circle (more or less) that is 9 billion km in diameter.
There is a lot more to our solar system beyond Neptune though, there are then the Kuiper belt objects further out, which include smaller rocks and ice lumps to larger dwarf planets - including Pluto. This extends out from around Neptune's distance to around 55AU - its a bit like the asteroid belt between Mars and Jupiter.
But the suns sphere of influence may then also include a large amount of matter that extends out as far as 50,000AU (or roughly one light year). This is called the Oort cloud, and it is believed to be where comets originate.
