    Hi Kristine,

    Thanks for contacting Jotform Support. Do you want to increase the signature field size on the form or do you want to increase the size of the signature on the PDF submission document of your form?

    If you want to increase the size of the signature field on the form build page, you can directly do that on the signature field properties tab.

    1. On the Form Builder, click the Gear icon on the signature field to open field properties.
    2. Now on the General tab, scroll down and enable Width and enter a width amount. You can also optionally change the height of the field too.

    If you want to increase the size of the signature on the original PDF after submission, there is currently no option to increase that from within the PDF Editor page.

    But if you create a new PDF document, you can show an enlarged signature, but it won't be on your original PDF. I checked your last edited form and it already shows that you've added a new PDF document on the PDF Editor page.

    1. On the PDF Editor page, click the Gear icon on the signature field.
    2. Now, on the Options tab on the right side pane, select Top aligned under Question alignment. This will automatically enlarge the signature. Keep the "Apply to all elements" checkbox unchecked, so that this question alignment is only applied to the signature field.
