You should start with

when you have your styling folders, there is a file


you should shange the line with

// Default Font Size & Color
$font-base-size:                        12px;

This might also be helping


Keep in mind, that depending on the theme you are using, there might be some fixed sizes on certain elements. You will have to adjust these manually.
