To make sure that you have a well balanced dialogue scene: color code your sentences.

Color code your sentences by highlighting and then right clicking on your mouse, then select your color:

Yellow for the dialogue

Blue for dialogue tags

Pink for internal thought

And purple for action tags

Color coding can allow you to see if you have an overbalance of say the internal thought verses dialogue. If the color is evenly distributed then you have the right balance.
