The minimum font size is about 16, and it is generally kept between 18 and 28.

2. Reading PPT (reading on mobile phone or computer):

The minimum font size is about 10, and it is generally kept between 12 and 16. Not smaller, but bigger. For special pages such as cover page, transition page and thank you page, you can use a larger font size, generally around 80. For example, a formal academic report has a title of 28 or above, a text of 18 or above, a picture title of 14- 16, and a document source (remarks) of 14- 16.

Generally speaking, the title of PPT on each page has the largest font on this page, followed by the subtitle. The text can be the same as the subtitle or smaller than the subtitle. The bigger the font, the better. If there is too much content, the bigger the font, which will lead to two fatal injuries: crowded pages and lack of focus.

Finally, when making PPT, when reducing the PPT page to 60%, if you can see the PPT clearly when sitting in front of the computer, there will be no problem in displaying PPT at that time.

Extended data:

When there are few words, you can use a larger font, but don't let the words fill the whole screen, leaving a certain space; When you are less, you can insert some pictures or gif animations that are not easy to attract attention in the spare place. You can use Enter or Move. If the text is all over the screen without leaving enough space for the edges, it will give people a sense of oppression.

So the specific font size depends on the specific PPT layout.
