Donald Trump’s signature
Few signatures are as instantly recognisable as Donald Trump’s. Tall, jagged peaks run across the page in thick black marker, so bold that it is often held up to the cameras after an official signing. Watch it being drawn below, then read what makes it so distinctive.
A row of sharp upward spikes on a heavy baseline. Commentators have compared it to a mountain range, a city skyline and an EKG readout.
Almost always a thick black Sharpie marker, which gives every line the same heavy width.
Very large and very wide. On official documents it often fills the whole signature block.
Low. The first name and surname merge into one rhythmic zigzag, with only the capital D and the final descender clearly readable.
A signature made for the cameras
During his presidencies Trump regularly turned signing ceremonies into photo moments. After signing an executive order or a bill he would lift the folder and show the signature to the press. The thick marker makes it readable even in photos taken from the back of the room, which is exactly the point.
Why the Sharpie matters
Trump signs almost exclusively with a black Sharpie. The marker became so closely tied to him that a 2019 hurricane map extended with a black marker was nicknamed "Sharpiegate". For a signature, a thick even line hides small wobbles and makes each stroke look confident.

What you can learn from it
You do not need spikes or a marker, but the idea behind it works for anyone: a signature with one clear rhythm, a strong first letter and a consistent size looks deliberate and is hard to imitate casually. That is the same principle our designers use for a Professional Signature.
Is it always the same?
Like every real signature it varies. Versions from the 1990s look looser than the tightly packed 2017 and 2025 versions on official documents, and the authenticity of signatures attributed to him has been publicly disputed more than once. That variation is normal and is one of the ways examiners tell real signatures from traced ones.
