Reason: Bootstrap 3 is setting font-size: 10px for html.

Solution:

.swal2-popup {
  font-size: 1.6rem !important;
}

my solution:

.swal2-container {
  zoom: 1.5;
}

@limonte @epexa Your solutions break icons:

Icon is broken because some properties use rem and other em. You need to add this CSS to fix it:

.swal2-icon {
  width: 5em !important;
  height: 5em !important;
  border-width: .25em !important;
}

Update. The CSS above breaks the other icons. Could you please solve it?
