King Charles III’s signature

Since September 2022 the King has signed official papers “Charles R”, a short name followed by a sweeping last letter and a long line underneath. The R is part of a centuries-old royal tradition, and the result is a signature that looks as formal as the documents it appears on. Watch it being drawn below.

Shape

Tall, narrow upright strokes for “Charles”, a large R at the end and one long line that sweeps underneath the whole name.

Where it appears

Royal assent to Acts of Parliament, warrants and letters patent, and the proclamation signed at his Accession Council.

Rhythm

Compact on top, then one wide gesture below: most of the width comes from the closing flourish and the underline.

Legibility

Medium. The first name compresses into upright strokes, but the capital C and the closing R make it easy to recognise.

The R that arrived with the crown

Before he became king, Charles simply signed “Charles”. After his mother’s death on 8 September 2022 he added an R at the end, short for Rex, the Latin word for king. It mirrors “Elizabeth R”, where the R stood for Regina, queen. The change is small on paper, but it turns a personal signature into the one a monarch uses for official business, and it is the detail that tells you at a glance which Charles signed.

Where the royal sign manual is used

A monarch’s signature is called the sign manual. It appears on royal assent to Acts of Parliament, on warrants that express the sovereign’s wishes and on letters patent. The most formal documents state that they are signed with the sovereign’s own hand. Not every letters patent needs a personal signature, because the monarch can sign a warrant approving the draft instead, and the finished text is then sealed with the Great Seal.

A table that went viral

The signature also made headlines for the wrong reason. At the Accession Council on 10 September 2022, when the proclamation was signed, the King showed visible frustration at an under-sized table crowded with items, and the moment spread online. It is a reminder that a signature is a physical act: the pen, the surface and the space all affect how a line comes out, even for a king.

What you can learn from it

The strongest lesson is how much a tiny addition can change a signature. One extra letter and a confident underline give “Charles R” an authority that the plain first name never had. Your own signature can borrow the idea: choose one or two features, such as a clear initial and a single closing stroke, and repeat them every time. A Professional Signature designed by us is built around exactly that kind of consistency.
