How to make your signature look professional
Five changes that make a signature look deliberate on contracts and business documents.
A professional-looking signature is not about decoration. It is about control.
Make one capital clearly bigger
A confident first letter is what people notice. Let it be about twice the height of the lowercase letters.
Keep a steady baseline
A slight upward or straight baseline reads as decisive; a drooping one reads as tired.
Finish the stroke
End with a clear exit stroke or a single underline instead of letting the last letter fade.
Design for a ballpoint
Most business signing happens with cheap pens on forms. If it only looks good in fountain-pen ink, simplify it.
Be consistent
The same signature on every document matters more than any style choice.
