Not directly, but you can resize text boxes.
Attendee names have various lengths, so our editor automatically adjusts the text to fit the size of the box. This way, long names are resized instead of getting cropped.
There is a hidden feature, it acts as a “maximum” font size, so if some very long text cannot fit in the size you set, it will still automatically shrink. But it gives you a way to prevent very short text from growing much larger than long text.
If you're interested in having this in your editor, please contact us.
