How is it possible to change the size of a node, for example:

     \draw  node[fill,circle]{} (0,0);%

How to make the circle smaller or larger?

@student I’m sure you use place nodes differently (“more corrent”) by now, though I want to add for other visitors, that you actually do not draw the node but only fill it (despite the \draw, yes). Also the node is only placed by default at (0,0). The last (0,0) bit is just a move to the coordinate (0,0). – Qrrbrbirlbel Mar 21 '13 at 3:57

The node size normally depends on the size of the content. Your node is empty so it is relative small. If you want to set the size manually use the minimum width and/or minimum height or set both at the same time using minimum size.

The circle shapes just uses the greatest of both values, otherwise you may be interested in the ellipse shape.

     \draw node[fill,circle,minimum size=2cm] {};

If you want to mark the node even smaller than it is in your question, set the inner sep value lower. It causes an empty node to still have some size. Best set it to 0pt and then use minimum size.

If you only fill the node and do not draw its border (as you do in your example despite the \draw command (that does not affect nodes on the path)), you might also set the outer sep to 0pt, so that paths will actually connect to it.
If you do not reference the node later, you could actually just use the circle path operator, where you can specify a radius very simple: \draw (0,0) circle [radius=<value>];

     \draw  node[fill,circle,inner sep=0pt,minimum size=1pt] {};

can you set a default value for "minimum size" within a document? – drevicko Jun 11 '15 at 4:20
@drevicko: Try \tikzset{minimum size=..}. If this doesn't work check the PGF/TikZ manual for an "every node" or similar setting. – Martin Scharrer Jun 11 '15 at 17:39
     \draw  node[fill,circle,scale=0.3]{} (0,0);%

Note that the size of the empty node is determined by inner sep and scale simply scales this down in your code. – Martin Scharrer Mar 16 '11 at 7:26
