I’m trying to generate an envelope. The text box for the sender is the wrong size (too high, not wide enough). Similarly, the text box for the addressee needs to be slightly higher. It only allows for 3 lines.
Which operating system do you use?
And which LibreOffice version?
Choose Insert>Envelope... from the menu.
On the Format tab in the Envelope dialog box, you can specify the location of the recipient and sender.
And with the button “Edit” you can set the font size.
In the “Envelope” tab, 10 lines each are possible for recipient and sender.
With me Windows 10 Home; Version 2004; 64-Bit | LibreOffice, Version: 7.0.2.2 (x64).
