Hello @sukron

There is no such setting in the theme to resize post title and date. But off course yes there is option available to do soo.

Please follow my instruction

Go to Admin Panel >> Appearance >> Customizer >> Additional Css, there you just add few css code then published and refresh, you will see the changes

Here is the Css Code

.custom-entry-date span.entry-day{
	font-size: 24px;
	width: 50px
}
.custom-entry-date span.entry-month{
	font-size: 14px;
	width: 50px;
	padding: 8px 12px;
}
.entry-title a{
	font-size: 16px;
}

You can change the title and date size as per your need from here.

Hope this helps

Thank you
