A question

Hello,
I am new to blender and I have a question:
Is it possible to disable font antialiasing in user interface, and use a custom font , for example Verdana, with larger font size than the default blender font?

Thank you for help in advance!

Yes. Pull down the User Preferences window by pulling down the top header (the one with File, Add, Timeline, et cetera.). It should be on language and font. Click International Fonts and you can choose the language, the font and the font size. Then put the User Preferences window back up and press Control U to save user preferences (note that this saves your entire blender setup including the window layout and what ever objects are in your scene.

Thank you for help!
I loaded Verdana. Is it possible to make the font sharper, because it seems a little blurry now
