Short answer: blow your own trumpet or toot your own horn depends on where your reader lives. Both mean to boast about your own achievements. "Blow your own trumpet" is the British and Commonwealth form, which Wiktionary labels that way. American dictionaries lead with "blow your own horn" or "toot your own horn." The trumpet version has the longer paper trail: The Phrase Finder gives Anthony Trollope in 1873 as the earliest printed example of the modern phrase, with the same idea in the King James Bible of 1611. For "toot," we found no dated first example in any named reference.
The three forms at a glance
| Form | Main region | Register | Earliest date given by the references we checked |
|---|---|---|---|
| blow your own trumpet | UK and Commonwealth (Wiktionary) | Casual to neutral | 1873, Trollope (The Phrase Finder); "late 1500s" (Dictionary.com, no example given) |
| blow your own horn | US | Casual to neutral | Dictionary.com's American Heritage entry says "late 1500s," with no example |
| toot your own horn | US | Casual | No dated citation found in a named reference |
All three are current. The horn versions are the everyday American choice, and "toot" is the more playful of the two.
What the phrase means
To blow your own trumpet, or toot your own horn, is to talk up your own achievements. Dictionary.com defines "blow one's own horn" simply as "to brag about oneself," with the example "Although usually modest, Marilyn had to blow her own horn a bit during the job interview." Wiktionary defines "toot one's own horn" as "to promote oneself; to boast or brag."
That example is worth noticing. The phrase is not always an insult. It can describe necessary self-promotion, like a job interview or a grant application, as well as tiresome bragging.
Common patterns:
- The disclaimer: "Not to toot my own horn, but I called this result months ago." Wiktionary gives almost exactly this example.
- The criticism: "He spends every meeting blowing his own trumpet."
- The encouragement: "Don't be shy about blowing your own trumpet in your cover letter."
Blow your own trumpet or toot your own horn: which is older?
The trumpet form is older in the references we checked, but the dates depend on what you count.
The Phrase Finder (Gary Martin). The Phrase Finder's entry on "blow your own trumpet," which we read on September 27, 2026, says the modern form dates to the 19th century. It names Anthony Trollope's Australia and New Zealand (1873) as the earliest known printed reference: "In the colonies… when a gentleman sounds his own trumpet he 'blows.'"
Look closely at that line. Trollope appears to be explaining a colonial use of "blow" to mean boast, and he does it by assuming his readers already know what sounding your own trumpet means. That suggests the image was familiar before 1873, even if no earlier printed example of the exact phrase has been found.
Dictionary.com (American Heritage idioms). Dictionary.com's entry for "blow one's own horn," read on September 27, 2026, dates the idiom to the "late 1500s" and lists "blow one's trumpet" as a variant. It does not quote a 16th-century example, so we cannot tell which wording it is dating.
Grammarist. Grammarist's page on the idiom says the phrase evolved from "blow your own trumpet" to "toot your own horn" during the mid-1900s. It gives no dated example for that shift either.
Putting that together: the trumpet image is old, the modern British wording is in print by 1873, and the horn wording is treated as the later form. How much later, and when "toot" replaced "blow," is not documented in the references we checked.
The older idea: trumpets before you
Long before anyone "blew their own trumpet," English writers used trumpets and blasts of sound for boasting.
The King James Bible, 1611. The Phrase Finder quotes Matthew 6:2, where Jesus warns against showy charity: "do not sound a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men." This is the same picture: making a noise about your own good deeds so others will notice.
Miles Coverdale, 1549. The Phrase Finder also quotes Coverdale's English version of the Paraphrase of Erasmus upon the Newe Testament: "Let them never so muche with their blasyng wordes boaste themselves." It explains that "blasing" was 16th-century slang for boastful speech, which puts a blast of sound and a boast side by side more than three centuries before Trollope.
Neither of these is the idiom itself. They show that the link between loud announcement and self-praise was already part of English. This is common with idioms: the image is old and the fixed wording comes later. The same thing happened with the proof is in the pudding, which was cut down from a longer 1605 sentence.
The royal herald theory
Many pages explain the idiom by pointing to heralds who blew trumpets to announce a king or a noble. The logic is neat: an important person had someone else sound the trumpet, so a person who has to blow their own is announcing an importance nobody else will vouch for.
Grammarist gives this as the origin. It is a reasonable reading of the image. But none of the references we checked quotes an early text that makes the link directly. Treat it as a likely explanation of why the image works, not as a documented first use.
A quote to be careful with
Several websites say "toot your own horn" is American from about 1776 and quote a motto, "Toot your own horn lest the same never be tooted," supposedly from the Warren-Adams letters. We could not find this quotation in any named reference, including The Phrase Finder, Grammarist, Dictionary.com or Wiktionary. Until someone points to the letter itself, it is best treated as unverified. Our guide to how a phrase origin is traced explains why a date without a checkable source should not be repeated.
Blow your own trumpet or toot your own horn: which to use
Pick the form your reader will hear as natural.
- British, Australian and other Commonwealth readers: "blow your own trumpet." Wiktionary labels it British and Commonwealth English. The horn versions are understood but sound American.
- American readers: "toot your own horn" or "blow your own horn." "Toot" is lighter and more playful; "blow" is slightly plainer.
- International audiences and ESL readers: either works, because the meaning is clear from the image. "Toot your own horn" may be the more familiar form through American media, but that is our judgment, not a measured figure.
- Business writing: fine in a friendly email or a team update, especially in the self-aware form "not to blow my own trumpet, but." In a formal report or a CV, drop the idiom and state the achievement plainly.
- Talking about someone else: "he's always blowing his own trumpet" is a mild criticism. It is casual, not rude, but it is not a compliment.
None of the forms is dated. All three are in everyday use.
