Thank you Bob Hanlon, David Park and Tomas Garza.
Indeed that is what I was looking for.

Use the option VectorScale

Needs["VectorAnalysis`"]

Clear[f]
f[x_, y_, z_: 0] = {y, -x, z};

rotF[x_, y_, z_] =
Curl[f[x, y], Cartesian[x, y, z]];

Partition[
VectorPlot3D[rotF[x, y, z],
{x, -1, 1}, {y, -1, 1}, {z, -3, 0},
VectorStyle -> "Arrow3D",
VectorScale -> #,
ImageSize -> 300,
PlotLabel -> #] & /@
{Tiny, Small, Medium, Large,
.07, {.04, .45, None}},
2] // Grid
