figure sizes dont work properly

Hi MATLAB community,

I have a problem with figure sizes.
I want to create many figures and then reposition them across my display.

(if there is any better way to write code in here please tell me)

function Fig = FigureAdvanced2
  ScreenInfo = get(0,'ScreenSize');
  ScreenWidth = ScreenInfo(3);
  ScreenHeight = ScreenInfo(4);
  
  FigWidth = 560;
  FigHeiht = 420;
  Border = 40;
  
  FiguresPerRow = floor((ScreenWidth - Border)/(FigWidth+Border));
  FiguresPerColumn = floor((ScreenHeight - Border)/(FigHeiht+Border));
  
  FigCount = length(findobj('type','figure'));
  Fig = figure(FigCount + 1);
  FigRow = ceil(Fig/FiguresPerRow);
  FigColumn = Fig - (FigRow-1)*FiguresPerRow;
  
  set(Fig,'Position',[FigColumn*Border + (FigColumn - 1)*FigWidth,...
                      ScreenHeight - FigRow*Border - FigRow*(FigHeiht - 1),...
                      FigWidth, FigHeiht]);
end

Since FigWidth and FigHeiht are constant in each call, i should get figures of the same size every time, right? Well I don't.

Any help appreciated!
