When you open a new window on a computer, it may be smaller than you would like. You can increase the size of computer windows in either your Mac or Windows computer in a few simple steps.
Locate the title bar options at the top right corner of the window. You will see the "Minimize," "Maximize" and "Close" buttons.
Click the "Maximize" button to expand the window to full screen. This is the button in the center that looks like a square.
Click the "Maximize" button again, which now looks like two small squares, to make the window small again.
Click and hold the edge of the window to be able to drag it to expand it. Release the mouse button to set it at the expanded position.
Click and hold the bottom right corner of the window.
Drag the corner to the size you prefer.
Release the mouse button when you have expanded the window to your liking.
