Yes. You can run NetBeans with the --fontsize <size> option.

The default value is 11. You can try to set it to 12 or even a higher value and see if it works better for you.

The --fontsize argument applies to fonts used in menus, dialogs and most components in the IDE. The size of fonts used in editors is also based on the --fontsize parameter as long as has not been customized by the user in Tools | Options | Editing | Editor Settings.

If you want to set the option permanently, you can do so in the netbeans.conf file.
