I often need to plot 10 images together, but using this code results in small images :
img = rand(400,600);
for i=1:10
subplot(2,5,i);
imshow(img);
title(
You can use figure properties option once you generate the plot. Click on the subplot which you want to resize. From property editor select 'more properties' option. There if you scroll you will see 'Position' tab. You can change those values to see how the subplot moves and thus adjust subplot according to your preference.
