Notepad++ set custom zoom

How can I set custom zoom in Notepad++? I want to set it to 90 or 110. The reason I want to do is I use Consolas and font size 10 is too small and 11 is too big.

The zooming functionality in Notepad++ actually works via changing the point size not by a 'custom' zooming display feature (ie. it's no different than you changing the font size).

Taken from Scintilla documentation (Notepad++ is based on Scintilla):

Scintilla incorporates a "zoom factor" that lets you make all the text in the document larger or smaller in steps of one point. The displayed point size never goes below 2, whatever zoom factor you set. You can set zoom factors in the range -10 to +20 points.
