Can i make the Emulator Screen Larger?

I just wanted to know... its the first time Ive used any emulators and I'm using the newest version of 'No$gba Emulator' and I'm kind of been trying to make the screen bigger so i can read things easier...I just wanted to know if it was possible and how to do it if it isn't too much trouble.
