eps figures do not have the correct size

Hello i'm trying to print some plots as eps file for my thesis. I want to plot them in the right size so the font is the same in every plot and i can use the width of the whole paper. I'am plotting my stuff like this:

width = 15.5; %size in cm (i'm using A4) 
high = 7;
ratio=high/width;
%------------------

xlim([-0.5*1/ratio*lim,0.5*1/ratio*lim]);
ylim([0,lim]);
%------------------

set(gcf,'paperunits','centimeters')
set(gcf,'papersize',[width,high])
set(gcf,'paperposition',[0,0,width,high])
print([filename '.eps'],'-depsc')

Why does the eps file have another size ( I only need the right with) then the 15.5cm I used? (I tested the size of the file with a pdf XChange viewer and Word 2010. Thank you in advance for any Help
