At first I was furious. I love grids and like things in proper order. So the number of posts on my page being out of my hands is something I can't stand. I have many posts that feature big images, so it was troublesome.
But my layout bears one advantage to that issue: I only displey one image and the title on the front page!
By adding <!--more--> right after my image into my posts, only the image and title's KB count, but not the rest of the entry.
Problem solved and I can relax xD
