Changing the fonts of a large word file or a PowerPoint presentation with a lot of slides can be either a real pain or a piece of cake. To experience the last, it is necessary to set up your document well from the beginning.
Starting from scratch, this is how it works:
Each theme can have two different fonts: one heading font and one body font. It is prefered to have maximum 2 fonts in this division as a lot of fonts can quickly appear messy, which makes a text more difficult to read.
Go to the tab ‘design’ and click on the drop-down menu ‘fonts’ > ‘customize fonts’, select two fonts you like to use and pick a name for the theme.
Whether or not you use styles (in MS Word) or slide master (in PowerPoint) make sure you always use this heading or body font troughout the whole document: just by choosing the theme fonts in the dropdrown menu on the home tab (Word or PowerPoint) or by doing the same for each style you use in Word.
Now all text is based on the theme fonts. So if you change the fonts of this theme or choose a complete other theme, all text in your document will change along.
No need to adjust the font of each slide (PowerPoint) or each style (Word) one by one, with a couple clicks of the mouse the job is done!
