Building on what rjt posted, you can use Text::Flow to format your paragraph constrained to a number of pixels of your choosing. In rough form:

use Text::Flow;
use Font::TTFMetrics;

my $text = 
'asdfk lasdjf asd flkasd fkjasdf la ksdf asdlkja sdkf laksdf laksdj aj
+sd
lkasdf alksdj flkajsdl falsd flkasd asd flkaj sdlkfja lsf alsdkf lksad
+jfl
asdfkj laksdf a sdkjf laksdjf kasdf lkasdfkja sdflka sdf asd flkajds l
+fka
sdflak sdflkajsd fkjal j adsfkj alsdf ads Some string';
$text =~ s/\n/ /g;

my $resolution = 72; # 72dpi typical, 96, 100, 120 common
my $pointsize = 12; # Whatever size the target text is
my $font = Font::TTFMetrics->new('georgia.ttf');
my $width = 200;   # Constrain to this number of pixels in width.

my $flow = Text::Flow->new(
      check_height => sub { 
          return 1;  # Should really enforce height constraint here
      },    
      wrapper => Text::Flow::Wrap->new(
          check_width => sub {
                my $string = shift;
                my $font_units = $font->string_width($string);
                my $pixels = $font_units * $pointsize * $resolution
                     / (72 * $font->get_units_per_em);
                return $pixels < $width;
          },
      )
);

my ($reflow) = $flow->flow($text);
print $reflow;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
