Hi All,

In my own user research, people with intellectual disabilities have reported they prefer large font sizes. Briefly, if people prefer large font sizes because they increase comprehension, I suspect it’s because larger font sizes push out distracting content such as advertisements.

Hi Steve,

Good question. From the Summary Conclusion however: "On overall preference, more than 50% of the UK participants chose 18 point sans serif, whereas more than 50% of Thai participants chose 18 point serif."

I recall back in the day when the W3C CSS WG established the base-line font-size for browsers at 16 pt., and then designers promptly modified their style sheets to: body {font-size: 80%;} (sigh)
