Signature size on form reduces after signing

Hello,

If the question I am asking has already been asked, then sorry, I did not see it.

I am creating a form to be signed by our customers using Adobe sign, but when the form is returned to us, the signature is very small when people just write their name instead of adding a digital signature.

How do I fix this. I have tried increasing the font, but it does not work.

Thanks for your help.

Michele
