Text size in figure relative to figure window

I am making a bar plot with some short text on the side. I noticed that when I increase the size of the window the figure is in everything scales except for the text. This causes the text to apear really small when the window is big and vice versa. How can i make sure the text has the same relative size as the figure window?

My code:

hold on

patch([-11 11 11 -11], [-11 -11 11 11],'w')

patch([-2 2 2 -2], [-8 -8 8 8],'r')

axis([-10 10 -10 10])

axis off

FB_text_ = text(6,2,FB_Instruction,'FontSize',25)

FB_text_ = text(6,2,FB_Instruction,'FontUnits','normalized','FontSize',25)

Try with FontUnits property set to normalized

Thanks! Worked perfectly when I changed the order to:

FB_text_ = text(6,2,FB_Instruction,'FontSize',25,'FontUnits','normalized')

Please accept the answer if it worked for you.
