P.S. There's a distinct issue related to the extra margin adjustment for the these scaled axis titles. But that requires a bigger refactor, which I'd rather tackle in a separate PR.

library(tinyplot)
tinytheme("clean", cex.axis = 3, cex.lab = 1)
tinyplot(1000:1010, xlab = "X title (JjQqYy)", ylab = "Y title (JjQqYy)",
         main = "cex.axis = 3, cex.lab = 1")
box("inner", lty = 2)

tinytheme()
tinytheme("clean", cex.axis = 1, cex.lab = 3)
tinyplot(1000:1010, xlab = "X title (JjQqYy)", ylab = "Y title (JjQqYy)",
         main = "cex.axis = 1, cex.lab = 3")
box("inner", lty = 2)

tinytheme()
tinytheme("clean", cex.axis = 3, cex.lab = 3)
tinyplot(1000:1010, xlab = "X title (JjQqYy)", ylab = "Y title (JjQqYy)",
         main = "cex.axis = 3, cex.lab = 3")
box("inner", lty = 2)

tinytheme()
