Johannes,

Hans will help you with the Context way, if there is one. What I like to do
is get the graphics the right size before I use them. I always use a
scaling factor in my MP code. For example, let's say I want a figure that
is 3 inches wide.

%initialize scale
numeric u; 5u=3in;

%initialize points
pair A, B, C, D, E;
A:=origin;
B:=(3u,0);
C:=(5u,0);
D:=(5u,3u);
E:=(0,5u);

%draw frame
draw A--B--C--D--B--E--cycle;

Note that this is exactly 3inches wide. Now, suppose I change my mind and I
want it to be 4inches wide. This is all I have to do:

%initialize scale
numeric u; 5u=4in;

%initialize points
pair A, B, C, D, E;
A:=origin;
B:=(3u,0);
C:=(5u,0);
D:=(5u,3u);
E:=(0,5u);

%draw frame
draw A--B--C--D--B--E--cycle;

Notice that nothing changes save my scaling factor. So, good advance
planning is a savior. I've attached some more code where you can see this
in action.
