The description of `text-scale-set' reads: C-h f text-scale-set RET ,---- | text-scale-set is an interactive autoloaded Lisp function in | `face-remap.el'. | | (text-scale-set LEVEL) | | Set the scale factor of the default face in the current buffer to LEVEL. | If LEVEL is non-zero, `text-scale-mode' is enabled, otherwise it is disabled. | | LEVEL is a number of steps, with 0 representing the default size. | Each step scales the height of the default face by the variable | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | `text-scale-mode-step' (a negative number decreases the height by | the same amount). `---- The first time `org-mode-hook' is run the height of default font is scaled by 4 levels, i.e. the height of default font is set to a new value. The second time `org-mode-hook' is run the height is scaled again, this time based on the new value. And so on. If you want to set the face height you might use: (set-face-attribute 'default nil :height 100) Here `100' means 100% of the font size in pt (afaik).
