I changed the FontSize, but it did not work

macOS Big Sur
the font size is quite small, I changed the fontsize parameter in config file, but it did not work.
when I changed other parameter, it worked normally.

I meant the size

in ~/.hyper.js have this setting
module.exports = {
config: {
// choose either 'stable' for receiving highly polished,
// or 'canary' for less polished but more frequent updates
updateChannel: 'stable',
// default font size in pixels for all tabs
fontSize: 31,
