(* I think the option ScaleFactor is what you need. Try: *)

Needs["VectorFieldPlots`"];
 
VectorFieldPlot3D[{x, y, z}, {x, 0, 1}, {y, 0, 1}, {z, 0, 1}, 
 ScaleFactor -> 1.5, VectorHeads -> True]

VectorFieldPlot3D[{x, y, z}, {x, 0, 1}, {y, 0, 1}, {z, 0, 1}, 
 ScaleFactor -> 0.25, VectorHeads -> True]

(* How did I find it out? Evaluate the following command: *)

Needs["VectorFieldPlots`"];
Options[VectorFieldPlot3D]

(* Mathematica will answer with a list of the possible options for
VectorFieldPlot3D,
Then you can search each one of those options in Mathematica's Help:

Asunto: [mg86277] Increase length of arrows in vectorfieldplot3d

Hi,
     Just using vectorfieldplot3d for the first time (plotting
computed normals of a surface f(x,y) as it happens..).  I can't seem
to increase the length of the vectors, even if I multiply the vectors
by 1000!  Using Mathematica 6.0.2.0.  Example:

VectorFieldPlot3D[
 1000*nrmDblSinClamp[x, y, boxXext, boxYext, 2, 1, 0.0, 20.0],
 {x, boxXext[[1]], boxXext[[2]]},
 {y, boxYext[[1]], boxYext[[2]]},
 {z, -2, 2},
 Axes -> True, AxesLabel -> {X, Y, Z}, VectorHeads -> True]
