Handling Superscripts and Subscripts in Photoshop

Objectives
To accurately map and display super or subscripts

Approach
When a text is made super/script, font size remains the same in photoshop
To make the superscript text appear smaller, 75% of actual font size is mapped to be displayed in an editor that I am using because editor converts the font size to 75% when a text is changed to super or subscript

Problems
There is a minor difference in the size for a superscript in photoshop and corresponding one in editor. How is the superscript made to appear smaller visually in Photoshop , if the font size remains the same. Should we multiple font size by a threshold like 75 upon making it superscript
