I have 3 monitors. In the middle one of them my taskbar is like twice it's size. Why?

Right clock on the 'big' taskbar and make sure that the lock all taskbars option is unticked.

Then with your cursor hover over the top of the taskbar until you see the cursor change to an up and down arrow.

Then left click and drag the taskbar down to reduce it's size or up to increase it's size.

Once you are happy right click and make sure that the lock all taskbars option is ticked.
