Resize font size automatically when app window size is enlarged

I have built an application. The font size of the application when "Not-enlarged" is perfect. But when enlarged the font sizes dont increase so the all the font sizes look out of place and too tiny in an "enlarged" window of the app. How do i make the font sizes to automatically chnage/adjust with window size.
I tried with the Normalise option but did not help. similarly autoresize children option ON does not help either.

Why didn't setting font units to normalized solve the problem?

You may try to use SizeChangedFcn callback to adjust the font size as a workaround.
The following example determine the new font size based ONLY on the vertical size of the figure. You may modify it according to your needs.
uif = uifigure;
defaultSize = uif.Position(4)-uif.Position(2); % Default vertical size of the figure
uif.AutoResizeChildren = 'off';
uif.SizeChangedFcn = {@changeFontSize,uif,defaultSize,fontSize};
fontSize = 12; % Default font size
uilabel(uif,'Position',[50 50 400 50],'Text','Change font size','FontSize',fontSize);
uitextarea(uif,'Position',[300 50 200 50],'Value','234','FontSize',fontSize);
function changeFontSize(src,event,uif,defaultSize,fontSize)
newSize = uif.Position(4)-uif.Position(2); % New vertical size of the figure
factor=newSize/defaultSize; % A factor to determine new font size
obj = findobj(uif.Children,'-property','FontSize'); % Extract objects with FontSize property
for k = 1:length(obj)
obj(k).FontSize = factor*fontSize; % Change to a new font size
end
end

The ideal solution is to set all font units to normalized.
Alternatively, you could use SizeChangedFcn in @Simon Chan's answer but instead of finding objects with a fontsize property, compute the change in figure size (newSize / oldSize) and use that ratio as a scale factor in fontsize(fig,scale=sfactor).
