This sounds like a silly question and it probably is but I'm building a website on top of Bootstrap and it uses 14px font size as a default. There is a lengthy discussion of various font sizes / line heights here but only 16px is mentioned as a possibly better value than 14px, never 15px.

When testing my site, 14px looks too small and 16px too big. 15px seems like a sweet spot but it is so rarely used that it leaves me wondering whether it might possibly cause some issues later on? Or is it just a matter of preference that most people decide between 14px and 16px and ignore 15px?

Answer 1

I'd imagine 16px and 14px are just preference given that they divide easier than odd numbers. If say you were to use em instead of px later on and wanted something to be .5 em or .25em, 14 and 16 px divides nicely compared to 15px. This may cause problems when those ems are converted back to pixels later on, but I don't think it would be much of an issue
