I would like to send Thunderbird messages with Calibri font and in 11 point size. The "medium" font size is 12 point and the "small" is 10. Is there a way to use 11 point? I know the recipient can have their viewer set at different viewing fonts. The issue is, on a string of messages when I have it set at medium/12, the font of my message is too big at 12 and too small at 10. 11 is the Goldilocks number--at least for me. Any suggestions?
