Headcanon Template: One Page, Thirty Lines

The headcanon template on this page is a working sheet rather than a worksheet: thirty numbered slots, five category headings, and one header line for the character name, the archetype and the date. It is sized for one character and one side of paper, and every slot on it can be filled by clicking the generator twice. If you would rather roll the lines first and find a sheet for them afterwards, the same grid is drawn in the diagram below and can be redrawn on the back of an envelope in about a minute.

Thirty slots arranged as the five categories by the six tones, with the first tone row shaded to show how a single pass fills one line in every column.

Why one sheet, and not one document

A generator returns a set, not a story. Thirty lines about one named character is a set with edges: you can see when it is finished, and you can see what is missing. That is the entire argument for paper. A notes file grows without a ceiling, so it never looks done; a sheet has a fixed budget, so it does. Thirty is also the size of the tool's own working unit, and it divides cleanly by everything above it — five categories, six tones, six lines in each cell.

The number is not arbitrary. The bank behind the generator holds 180 hand-written lines, arranged as 5 categories by 6 tones with exactly 6 lines in every one of the 30 cells. All 180 texts are distinct, and each category contributes 36 lines while each tone contributes 30. One filled sheet is therefore 30 of those 180 lines, or 16.7% of the whole bank, and each of its five columns is 6 of that category's 36 lines — the same 16.7%, in a different slice. A page is not a sample of the bank. It is a complete, closed subset, and that is what makes it printable.

There is a second reason to keep the unit small. A character sheet that lives in a document invites you to keep writing until the character feels finished, which never happens. A sheet that lives on one side of paper invites you to stop, print, and go and use it. If you want the reasoning for how many lines a character actually needs, the three budgets in the 30-cell matrix cover that; the page below is the ceiling, not the quota.

The template

Print this, or copy the structure into any notes app. Five blocks, six slots each, and a header. The dotted rules are the writing lines; the numbers are the slot numbers from the diagram, so a line written into slot 16 is a Relationships line in the Angsty tone, and you can find it again in the tool by setting exactly that pair of filters.

Three details in the header are doing work. The name is not decoration: capitalisation is part of what the tool hashes, so Odette and odette produce different sets, and a sheet without the name on it cannot be rolled again. The archetype is a separate output — the tool draws one of 24 labels on every roll and prints it above the lines — and it is not one of your thirty slots, so if you do not write it down it is gone. The date matters more than it looks: with one sheet per character, the date is the only thing telling you which of three drafts of that character you are holding.

Filling it in six passes

The sheet is filled one tone at a time, not one category at a time, and the reason is mechanical rather than aesthetic. Inside a single roll the draw works around the category list in a cycle and never takes two lines from the same category. I tested this rather than assuming it: across 40 names and 20 seeds each — 800 rolls at a count of five — every single roll returned lines from exactly five different categories, with no repeats. Not 799 out of 800. All of them.

• 1. Type the name. Capitalise it exactly as you want it on the sheet. Nothing typed here leaves the tab, which the two-minute offline test shows how to confirm for yourself.
• 2. Set the count to 5. The count buttons re-roll the moment you press them, so the five lines on screen are the seed-1 five for whatever filters are lit at that moment.
• 3. Leave one tone lit. Switch the other five off. Each chip press re-rolls at seed 1 too, so when only Wholesome is lit you are looking at the Wholesome five: one line in Personality, one in Backstory, one in Relationships, one in Quirks, one in Secrets. Write those five into the Wholesome row, one per column.
• 4. Repeat for the other five tones. Six passes, five lines each, thirty slots. Each column ends up with six lines, one from every tone, which is a balanced page by construction rather than by luck.
• 5. Repair single slots with the per-line reroll. If one line is unusable, the small reroll control under that card replaces only that card and leaves the other four alone. Do that instead of re-rolling the whole pass, which would cost you four good lines.

The alternative is faster and worse. Leave all six tones lit, set the count to 5, and press generate six times: you get thirty lines and no control over the mixture, which in practice means four Angsty columns and nothing Romantic. That is fine if you are browsing. It is the wrong method if the point is a page you can read from top to bottom, because the tone spread is the only structure the page has.

What each slot is drawn from

Every number below was counted out of the single source file the tool runs from, not estimated. They are the reason the six-pass method is exact rather than approximate.

• The bank is 180 lines, and all 180 are distinct. Five categories by six tones with six lines in every cell, so no two cells ever hand you the same sentence.
• Per category: 36 lines. Per tone: 30 lines. A column on your sheet takes six of that category's 36, one from each tone, which is why a balanced page never pulls three lines from the same mood.
• Every cell holds exactly six lines. That is the pool behind a single slot when you know both its category and its tone, and it is also the reason two sheets collide at a predictable rate — see below.
• One page is 30 of 180 lines, or 16.7% of the bank. Six of 36 in each column is the same 16.7%. A full folder of ten characters has spent 300 slot-fills and still cannot hold more than the 180 lines that exist.
• Thirty slots, six options per slot, is 6^30 possible balanced pages — about 2.2 × 10^23 of them. The supply of distinct pages is effectively unlimited even though the supply of sentences is not, and that gap is exactly where the honest advice lives.
• A line runs 46 to 143 characters with the name counted as a single character, median 80.5, or 9 to 26 words with a median of 15. Size the writing lines accordingly: most lines need one ruled line, the longest need two. The blocks above give every slot one full-width line so the short ones have room to breathe.

Two pages share about five lines

Here is the part that no sheet template gets to hide. A slot's pool is six lines, so when two different characters land on the same slot they draw the same sentence one time in six. Over thirty slots that is 30 × 1/6 = 5.0 shared lines, and the measured figure across 20,000 random pairs of different characters is 5.048 out of 30. Your second character's page and your first character's page will agree on roughly five sentences, and no amount of care in the header changes that.

The practical consequences are small but real. Keep the used sheets, and when a line appears on two pages decide which character has the better claim to it before you write it into prose — the same sentence spoken by two people in one manuscript reads as a tic. If both characters genuinely need it, rewrite one of the two in your own words rather than re-rolling, because a re-roll only moves the collision to a different slot. And read the sheet for repeated props before you print it: on the worked page below, the word drawer shows up in two different slots and friend in three, which is the sort of thing you notice on paper and never notice on screen. If you want the underlying arithmetic of a fixed pool, why a generator repeats works through it with the same 180 lines.

One sheet, filled in

The page below is the output of the exact method above, not an illustration. To reproduce it: open the generator, type Odette, set the count to 5, then light one tone at a time and copy the five lines that appear. Nothing was re-rolled and nothing was hand-written. The tone is labelled on every line so the structure is visible: one line per tone, per category.

Personality — 6 slots.

• Wholesome. Odette keeps spare umbrellas by the door purely to hand them out, and never asks for them back.
• Funny. Odette has a strong opinion about how a dishwasher should be loaded and will defend it in front of a committee.
• Romantic. Odette loves in logistics — rides offered, food delivered, doors held three steps early.
• Angsty. Odette has learned to apologise before they know what they did, just to keep the room calm.
• Chaotic. Odette holds confident opinions about subjects they learned about forty minutes ago.
• Melancholy. Odette smiles half a second late when they are remembering something they would rather not.

Backstory — 6 slots.

• Wholesome. Odette spent every summer in the same small town and still measures a good year by whether they got back.
• Funny. Odette learned to cook from a cookbook with the pages in the wrong order, and the food is still slightly off.
• Romantic. Odette keeps a letter they never sent, folded the same way, in the same drawer.
• Angsty. Odette grew up apologising for taking up space, and still does the maths before sitting down.
• Chaotic. Odette has moved eleven times and still owns a box labelled miscellaneous, do not open.
• Melancholy. Odette still orders for two out of habit, catches it, and orders for two anyway.

Relationships — 6 slots.

• Wholesome. Odette is the only one who ever actually confirms the plan, and does it every time.
• Funny. Odette and their best friend communicate mostly in references nobody else understands.
• Romantic. Odette is brave about everything except the forty seconds before saying something true.
• Angsty. Odette loves people at a distance, convinced that closer would be worse for everyone involved.
• Chaotic. Odette has a friend for every activity they have ever quit.
• Melancholy. Odette still refers to an old friend in the present tense.

Quirks — 6 slots.

• Wholesome. Odette leaves the last of the coffee for whoever comes down next.
• Funny. Odette says on my way from locations that are not on the way.
• Romantic. Odette texts a photo of the sky whenever it is doing something interesting.
• Angsty. Odette double-checks the lock three times and still gets up once more.
• Chaotic. Odette starts a sentence, changes their mind halfway, and finishes it as a completely different sentence.
• Melancholy. Odette keeps the radio at low volume even when they are alone.

Secrets — 6 slots.

• Wholesome. Odette keeps every thank-you note they have ever received locked in a drawer, sorted by year.
• Funny. Odette has been about to learn how to swim for eleven years and stands by the plan.
• Romantic. Odette has imagined one conversation so many times that it feels like it already happened.
• Angsty. Odette has never told anyone that being needed and being wanted feel like very different things.
• Chaotic. Odette once solved a problem so creatively that they have never admitted to it.
• Melancholy. Odette has practised saying the truth out loud and decided that their silence is kinder.

Two things are worth noticing in that page, because they are what a sheet gives you that a scrolling list does not. First, the whole top row can be played in the opening scene without any setup: an umbrella handed out, an opinion about the dishwasher, a ride offered. The bottom row cannot — a drawer of thank-you notes and a sentence about being needed rather than wanted are endgame material. The page arrives pre-sorted by tone, and tone is a rough proxy for when a line can be spent. Second, the page contains one line that states no behaviour at all: being needed and being wanted feel like very different things. Every other slot can be filmed. That one is a theme wearing a slot's clothing, which makes it the first candidate to rewrite into an action or to delete without regret.

Reading order, and what to cut

• Spend the top rows first. Wholesome and Funny are scene-ready and cheap to place. If a character only gets one scene, the sheet has already told you which six lines to use.
• Hold the bottom rows back. Chaotic and Melancholy are the lines that mean more once the reader knows the character. Placing a Melancholy line in the first paragraph spends the ending early.
• Cut without guilt. Thirty is a ceiling, not a target. A page with twenty-two good slots and eight crossed out is a finished page; the crossing out is the work.
• One sheet per character, always. Because two pages share about five lines, a shared sheet guarantees a collision you cannot see. Separate pages make the overlap visible, and visible overlap is fixable.

Printing it, and keeping it offline

Print at A4, portrait, default margins, with the page set to about 11 point. Thirty dotted slots plus five headings fit on one side with room for the header; if you would rather have the grid form, lay the five columns across the page in landscape and number the cells as in the diagram, so slot 16 stays Relationships in the Angsty tone no matter which layout you chose. Two-sided printing is the natural fit: the sheet on the front, your own notes on the back.

The sheet is a file you own, and the tool that fills it is a single page with no upload step and no account to create — the same property that lets it work with the network disconnected. That combination is what makes this template worth printing instead of pasting into a hosted document: nothing about the page, the lines, or the character's name needs to leave your machine, and a paper copy cannot be re-sold to you as a subscription. For a table of one-scene non-player characters, where thirty lines is far too many, the short version of this sheet is in the five-line NPC method.

Quick answers

• Do I have to use the generator to fill this template? No. The grid is a layout for thirty lines about one character, and your own lines work in it. The tool only makes the first pass fast, and it makes the fill rate measurable.
• What if I cannot fill all thirty slots? Stop and print it anyway. The page records what you know, and the empty slots are a to-do list that the layout keeps visible. A page with a third of its slots blank is more useful than a document that looks complete and is not.
• Should the same line appear on two characters' sheets? It will, about five times per pair. Keep the sheet that has the stronger claim to the line and rewrite the other, unless the echo is deliberate.
• Can I use one sheet for a whole party? Not usefully. Each page is addressed to one name, because the name is part of what generates the lines. Four members means four sheets, and the shared lines between them become a map of where the characters overlap; the party method covers the edges that a page-per-character approach leaves out.
