假如你在800*600的分辨率下的form,第一步：
inplementation
const
ScreenWidth: LongInt = 800; {I designed my form in 800x600 mode.}
ScreenHeight: LongInt = 600;

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
scaled := true;
if (screen.width <> ScreenWidth) then
begin
height := longint(height) * longint(screen.height) div ScreenHeight;
width := longint(width) * longint(screen.width) div ScreenWidth;
scaleBy(screen.width, ScreenWidth);
end;
end;

下一步，要每个子控制的字体改变到合适的大小：
type
TFooClass = class(TControl); { needed to get at protected }
{ font property }

var
i: integer;
begin
for i := ControlCount - 1 downto 0 do
TFooClass(Controls).Font.Size ]).Font.Size;
end;
