Format Position and size of plots

Hi, I have a few plots (.fig) I need to reformat (examples attached). Somehow the size of the plot itself got bigger in some figures and the position of xlabel and ylabel changed. I need to reformat by code so they are all equal.

I tried doing it like this:

set(gcf,'windowstyle','normal')  %undocked the figure
set(gcf,'Position', [1 1 967 700])
a=title('HEllo') %redo the title so I can name it with 'a'
set(a,'Position',[ 0.3480e3    1.3e3    0.0010e3])

c=xlabel('X')
set(c,'Position',[ 350 -110 1])

d=ylabel('Y')
set(d,'Position',[-86  597 1])

set(gcf,'papersize',[22 18])
set(gcf, 'PaperPosition', [0 -1.75 25 20]);

print -painters -dpdf -r300 test.pdf

I did this for two plots but somehow one is bigger than the other... You can check the .pdf attached. Can someone explain me or tell me how I can correct it?

Many thanks!
