How can one determine the optimal character limit per line for content in a PDF generated with html2pdf?

To determine the optimal character limit per line for content in a PDF generated with html2pdf, you can calculate the average width of characters in the chosen font and divide it by the width of the PDF page. This will give you an approximate character limit per line that will ensure text does not overflow or wrap awkwardly. 

// Calculate the average width of characters in the chosen font
$font_size = 12; // Set the font size
$font_family = 'Arial'; // Set the font family
$average_char_width = imagettfbbox($font_size, 0, $font_family, 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890');
$average_char_width = ($average_char_width[2] - $average_char_width[0]) / strlen('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890');

// Get the width of the PDF page
$pdf_width = 210; // Set the width of the PDF page in mm

// Calculate the optimal character limit per line
$optimal_char_limit = floor($pdf_width / $average_char_width);

echo "Optimal character limit per line: " . $optimal_char_limit;
