Limit font scaling with calc() permalink
If you would like set an exact minimum font-size in pixels you can use calc().

:root {
  font-size: calc(16px + 3vw);
}

Limit font scaling with media queries permalink
You can prevent the text from scaling below a specific threshold simply by using a media query and only applying viewport units above a certain device resolution.

:root {
  font-size: 18px; /* default below 600px */
}
@media (min-width: 600px) {
  :root {
    font-size: 3vw;
  }
}
We can also stop scaling above a specific font-size, but for this we need to first work out what the viewport size will be at the font-size we want to stop scaling. For that we need a bit of maths:

font-size / ( number of viewport units / 100 )
Eg. 24 / ( 3 / 100 ) = 800px
With that result just set another media query to change the root font-size back to a fixed unit.

... @media (min-width: 800px) {
  :root {
    font-size: 24px; /*above 800px */
  }
}
The calculations are not that hard but I find it easier to look at a simple table. This helps me visualise the change in font-size across different resolutions.

Viewport units:	1vw	2vw	3vw	4vw	5vw
Viewport size	font-size in pixels
400px	4px	8px	12px	16px	20px
500px	5px	10px	15px	20px	25px
600px	6px	12px	18px	24px	30px
700px	7px	14px	21px	28px	35px
800px	8px	16px	24px	32px	40px
900px	9px	18px	27px	36px	45px
1000px	10px	20px	30px	40px	50px
Looking at the table you can see there are many limitations. We have little control over the rate at which viewport units change and we are confined to the options available in the table.
