Below is my attempt, but would be grateful of any suggestions on how to c

Hi you can change font size directly in valueBox with a p tag without rewriting valueBox function (if you want you can, just wrap value and subtitle args in tags$p), try :

library("shiny")
library("shinydashboard")

# header
header <- dashboardHeader(title = "Changing the font size of valueBoxes", titleWidth = 450)

# sidebar
sidebar <- dashboardSidebar(disable = TRUE)

# body
body <- dashboardBody(
  valueBox(
    value = "90k",
    subtitle = "some long descritptive text",
    icon = icon("car")
  ),
  valueBox(
    value = tags$p("90k", style = "font-size: 150%;"),
    subtitle = tags$p("some long descritptive text", style = "font-size: 150%;"),
    icon = icon("car fa-lg")
  ),
  valueBox(
    value = tags$p("90k", style = "font-size: 200%;"),
    subtitle = tags$p("some long descritptive text", style = "font-size: 200%;"),
    icon = icon("car fa-2x")
  ),
  valueBoxOutput(outputId = "mybigbox")
)

# server
server <- function(input, output) {
  output$mybigbox <- renderValueBox({
    valueBox(
      value = tags$p("90k", style = "font-size: 300%;"),
      subtitle = tags$p("some long descritptive text", style = "font-size: 300%;"),
      icon = icon("car fa-3x")
    )
  })
}
shinyApp(ui = dashboardPage(header, sidebar, body), server = server)
