How to reduce a figure size within the plotting area and adjuste it to be centralized?

I want to to adjust the plotting area of this figure,

so, when I save the figure it will have it with a reduced white area arounding it.

I have tried the following

f1 = figure(1);
FigSize12 = get(f1,'position');
% f1.Units = 'pixels';
f1.Position = [600 400 FigSize12(3) FigSize12(4)/2.75];

And I get:

But, doing that I am not able to reduce the width and my figure is not centralized within the plotting area. As I need to do this procedure for many figures I need also to be able to control the length and the width using the figure properties.

Have you looked at the PaperPosition property of figures?

It is not clear how you are saving the figure?

Yes, I do.

I am saving the figures using

print(f1,'-dpng','-r300',fullfile([pwd subfolder ...
    'Nonlinear_Def_Mesh_InterpScheme=ON_F=12kN.png']));

Adjusting the Position property does not change the PaperPosition property.

I know, but take a look at this:

set(gca,'LooseInset', max(get(gca,'TightInset'), 0.05))

I got centered figures, but sometimes that's not you want!

To reduce the figure size and to centralize it, you may make use of the manual option of the PaperPosition property of the figure. This allows us to change the position and dimensions of the printed figure.

The following code snippet illustrates the usage.

set(gcf, 'PaperPositionMode', 'manual'); 
set(gcf, 'PaperUnits', 'inches'); 
set(gcf, 'PaperPosition', [2 1 4 2]); 

It sets the figure size to a width of 4 inches and height of 2 inches, with the origin of the figure positioned 2 inches from the left edge and 1 inch from the bottom edge.

When you set the PaperPosition property yourself then matlab automatically sets PaperPositionMode to manual
