Please advise which will be the easy way to increase the top bar size as well as font size.

Font size of the top bar is set by your GNOME Shell theme. The default GNOME Shell theme of Ubuntu 18.04 is dictated by the ubuntu.css file in your /usr/share/gnome-shell/theme/ directory.
After opening the /usr/share/gnome-shell/theme/ubuntu.css file you should find a stage section near the top, which would look something like the following:
stage {
font-family: <font-to-display>;
font-size: <size-of-the-displayed-font>;
color: <colour-of-the-displayed-font>; }
Change the value for font-size and save the file (note that you'll need root privilege to edit this system file). This would change the font-size of various components of GNOME Shell including the top bar in a consistent manner. You need to reboot or relogin or restart GNOME Shell to see the effect.
Note: It's not generally advisable to edit a system file, especially without backing it up. You can alternatively override your GNOME Shell theme from your local directory, refer to this.
