Unfortunately there does not seem to be a setting to change the barcode size - so this has to be done in code.
The relevant code is in /usr/share/koha/lib/C4/Labels/Label.pm . You will find, at the lines 220-260, 4 fuctions corresponding to the print types BIB BAR BIBBAR BARBIB. Depending on what you are using you can change only that function or you just change all of them.
Those functions define a barcode width witch is multiplied by 0.8 remove that factor or adjust it to your liking. for me the resulting BIBBAR function looks like:
sub _BIBBAR {
my $self = shift;
my $barcode_llx = $self->{'llx'} + $self->{'left_text_margin'};
my $barcode_lly = $self->{'lly'} + $self->{'top_text_margin'};
my $barcode_width = 1.0 * $self->{'width'};
my $barcode_y_scale_factor = 0.012 * $self->{'height'};
my $line_spacer = ($self->{'font_size'} * 1);
my $text_lly = ($self->{'lly'} + ($self->{'height'} - $self->{'top_text_margin'}));
$debug and warn "Label: llx $self->{'llx'}, lly $self->{'lly'}, Text: lly $text_lly, $line_spacer, Barcode: llx $barcode_llx, lly $barcode_lly, $barcode_width, $barcode_y_scale_factor\n";
return $self->{'llx'}, $text_lly, $line_spacer, $barcode_llx, $barcode_lly, $barcode_width, $barcode_y_scale_factor;
}

How to adjust font size of the barcode number that just below to the bar line.

Oh wow, I did not think someone would actually read my blog post! Unfortunately, I do not know where to change the font size. I also do not know any PHP, which is why I needed to solve this issue above with "pattern matching". It is probably best to look for someone more knowledgeable than me to solve the problem.
But the solution to your problem is most probably in that file mentioned above.

As said, I'm not sure how to do that, this post was more a 'note to future self'. But thank you for reading. You could try asking on the koha mailing list.
