Open a blank document in Word and click on the Format menu and choose Font. Change the font to one that you like and, if you wish, make other changes, like font size, then click on the Default button at the bottom-left of this box.

yes , when you open word and you click the tool that looks like AA and it says normal, you can click the down arrow.

then, click the more options. from there you can select your font size and color for your custom style, and it will stay like the when ever you open your word, untill you change it again
