The View menu gives you two ways to adjust the size of the VMware Virtual Machine Console window so it exactly fits the virtual machine's display.

Autofit is toggled on or off each time you click it. When Autofit is on, the console window adjusts automatically to fit the virtual machine's display. When it is off, you can adjust the console window to a size of your choice. If you make the console window smaller than the virtual machine's display, scroll bars appear so you can move to the part of the virtual machine's display that you want to see.

If Autofit is off, you can choose View > Fit to adjust the console window so it fits the virtual machine's display.
