The font in which signatures and texts appear is a standard font, therefore the font cannot be changed. You do have influence on how large the texts ultimately end up in your signed document(s).
The larger you make a (signature) field, the larger the final text will be. The length of the text also affects its size. For example, if there are two signers, one of whom has a short name and the other a long name, and you add two signature fields of equal size, the short name will appear larger in the document than the long name.
You can adjust the size of the text. When you select a text box, you have the option to adjust the font size on the right. This is also possible with a signature field.
