Harlequin is 187 cm tall, the shortest of the five introduced characters, and the youngest of the five in the developer's published age order. Both facts are documented. The specific age that circulates for him online usually is not — and in most cases it contradicts the one age statement the developer has actually made.
Height, age order, and strength ranking are taken from the developer's published chart and AMA answers. Costume description, personality summaries, and any specific age or birthday come from the fandom wiki and are marked as fandom-derived. This article does not treat an in-fiction estimate as a measurement.
The height: 187 cm
Harlequin's entry in the developer's height chart reads 187 cm, roughly 6 ft 1.62 in. That makes him the shortest of the five introduced characters, standing 20 cm below the Doctor at 207 cm, 11 cm below Pierrot, 5 cm below Jester, and 4 cm above the Ticket Taker.
The interesting part of that number is what it pairs with. Harlequin shares second place in the developer's strength ranking with Jester, behind Pierrot and ahead of the Doctor and the Ticket Taker. The fandom wiki reads that combination — youngest and shortest, but tied for second strongest — as the reason Harlequin is written as quick and physical rather than heavy. That reading is interpretation, but it is interpretation built on two published numbers rather than on a guess.
The age order: last of five
The developer's age order, oldest first, is Ticket Taker, Doctor, Pierrot, Jester, Harlequin. Harlequin is fifth — the youngest of the introduced cast, and the youngest of the two romance leads by two positions.
This is a genuinely documented fact and one of the most frequently mangled online. A large amount of fan material assigns Harlequin a specific numeric age, and several of those numbers cannot be reconciled with a published order that places him below a much older Ticket Taker and Doctor and above nobody. The order is the reliable version, and it is also the only version that exists: no numeric age has been published for any character in this game.
Write "the youngest of the five introduced characters" rather than a number. It is accurate, it is sourced, and it survives the next update. Numbers assigned to this cast by fan sites have a habit of being contradicted by later AMA answers, which is exactly why the developer publishes an order instead of a number.
The eleven-centimetre gap
Harlequin is 11 cm shorter than Pierrot, and that difference is large enough to read on screen without being exaggerated. The fandom wiki treats the gap as meaningful to the way the two leads are staged against each other — the silent one filling the frame, the theatrical one moving around it. Whether that was the design intent or a consequence of the sprite reference is not something the developer has stated, so it stays in the fandom column.
What is confirmed is simpler: the chart was published by the developer as a reference used when drawing sprites, which is why the numbers are treated as canonical rather than read off artwork. If a piece of fan art draws Harlequin as taller than Pierrot, the art is stylised; the official figures remain 187 and 198.
What the official material says about him
Beyond the charts, the developer has said several things about Harlequin directly. The official synopsis calls him Pierrot's "seductive rival" and describes the game as being led by one or the other — the clearest possible framing of a story with two romance routes and no others.
One AMA answer is worth quoting carefully because it is easy to misread. Asked about the bites Harlequin leaves while flirting, the answer was that they are not marriage proposals, that the mark leaves no scar, and that marriage and courtship among monsters work differently from how the protagonist would understand them. That small exchange does real work: it establishes that Harlequin's flirtation runs on the circus's own logic, and that the protagonist's frame of reference is not the frame of reference of the people around them.
The fandom wiki adds that Harlequin feels safe around the Doctor, that the Doctor is his favourite person in the circus, and that he gets along with the Ticket Taker despite a clash of tastes. It also records an implied link to Columbina's death — that Harlequin killed her to "save" her — which the wiki itself frames as implication rather than statement. The general shape of the circus's history is confirmed in AMA answers; that specific reading of Harlequin's role in it is not first-party.
Route status: planned, not playable
A Harlequin romance ending is one of the four conclusions the developer has named, alongside Pierrot's, the Protagonist's, and the combined "All together" ending. None of the four is implemented. The current build contains exactly one ending — the "Missing" bad ending on Day 1 — so there are no trigger conditions to publish and no honest walkthrough to write.
- Confirmed: his height, his last place in the age order, his tie for second in strength, his description as Pierrot's "seductive rival", the clarification that his flirtation bites are not proposals, and that a Harlequin romance ending is planned.
- From the current build: his appearance, his scenes, and the fact that some of his appearances vary depending on the story branch, which is confirmed by an official bug note.
- Fandom-derived: the mask description — white mask with a green diamond and a green triangle, venom-green eyes, curly black hair with a heart-shaped lock — his personal history, and the specifics of his relationship with Columbina.
Putting the numbers together
Harlequin's official measurements describe a specific character: the youngest, the shortest, and tied for the second strongest of a five-person company, who competes for attention with the second tallest and strongest member of that same company. He is not physically dominant and he is not inexperienced — he is quick, theatrical, and operating from a position where the rivalry is genuinely close. That is a good deal more useful than a made-up age, and it is fully documented.
