Hi Jeanlucgarnier,

To increase the font size of the the latest article title go to Appearance -> Customize/Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on Save & Publish button.

#main .widget_recent_entries ul li {
    margin-bottom: 10px;
}
#main .widget_recent_entries ul li a {
    font-size: 15px;
}

Thank you!
