+## Description
+
+This is an example of how to use font_scale_divisor and bold_font_multiplier to fine-tune the automatic column width calculation.
+
+## Code
+
+```ruby
+require 'axlsx'
+
+p = Axlsx::Package.new
+wb = p.workbook
+wb.font_scale_divisor = 11.5
+wb.bold_font_multiplier = 1.05
+s = wb.styles
+sm_bold = s.add_style b: true, sz: 5
+m_bold = s.add_style b: true, sz: 11
+b_bold = s.add_style b: true, sz: 16
+ub_bold = s.add_style b: true, sz: 21
+sm_text = s.add_style sz: 5
+m_text = s.add_style sz: 11
+b_text = s.add_style sz: 16
+ub_text = s.add_style sz: 21
+
+wb.add_worksheet(name: 'Line Chart') do |sheet|
+ sheet.add_row(['Lorem', 'Lorem', 'Lorem', 'Lorem', 'Lorem', 'Lorem', 'Lorem', 'Lorem', 'WWW', 'www', 'iii', 'iii',
+ 'Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed',
+ 'Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed'],
+ style: [sm_bold, m_bold, b_bold, ub_bold, sm_text, m_text, b_text, ub_text,
+ b_bold, b_text, b_bold, b_text, b_bold, b_text])
+end
+
+p.serialize 'fine_tuned_autowidth_example.xlsx'
