Orgmode title levels height

Question

I'm trying to set the font sizes of org-mode titles.
They are, by default, too big (yeah, size does matter).

I've been trying to find a reference, but very annoyingly, I couldn't.
How do I customize the scale value of all headlines through my config file?
Via group settings inside emacs --> org-faces I've found that it's set to height and scale.
I want to set all scales to 1.

Found the answer. Too obvious, but still annoying.

(custom-set-faces
  '(org-level-1 ((t (:inherit outline-1 :height 1.0))))
  '(org-level-2 ((t (:inherit outline-2 :height 1.0))))
  '(org-level-3 ((t (:inherit outline-3 :height 1.0))))
  '(org-level-4 ((t (:inherit outline-4 :height 1.0))))
  '(org-level-5 ((t (:inherit outline-5 :height 1.0))))
)
