data=Table[{{x,y},{1,0}},
{x,-2,2,1},{y,-2,2,1}];
?VectorScale
VectorScale is an option to VectorPlot, ListVectorPlot, and related
functions that determines the length and arrowhead size of field vectors
that are drawn. >>
ListVectorPlot[data,
VectorPoints->All,
VectorStyle->("Left"<>"Arrow"),
PlotRangePadding->1,
VectorScale->1/(4Sqrt[2])]
