Thank you for contacting Syncfusion support.
Query #1: “I want to increase the BackHeader's button size and to remove the text trimming. I tried to copy the template of the ribbon to use the style for the ribbon button but with no result”
In our Ribbon control, we have provided a constant width to BackStageButton and it cannot be increased. So, when BackStateHeader value exceeds the actual width of the BackStageButton, text trimming will be applied.
Query #2: “I tried to use the WordArt32.png to have bigger images when bars are collapsed”
In our Ribbon control, we have provided the constant width and height to RibbonBar collapsed image like MS Outlook collapsed RibbonBar. So, the collapsed image height and width cannot be changed
