One Family, Three Sizes

A photograph with type laid over it — held to one typeface, three sizes fixed by ratio, and one accent, so the poster reads as designed rather than assembled. Five fields.

Two runs of the same template. Holds again - one family, three sizes, yellow on the tag line only, headline placed in the pale sky. Worth recording: the hauled-out boat carries the registration PZ 682 on its bow, which the fields did not supply. It is a real thing on a real boat rather than a designed element, but the template says only the words the fields give, and a photograph will bring its own text with it whether you asked or not.

One grotesque throughout, where the reference run put six faces on one sheet - a gothic headline, a condensed subhead, a light sans in capsules, a high-contrast italic script and two more besides. The headline sits on the dark empty paving, which is the quietest region of the photograph, and the four small lines are aligned in pairs across the top and the foot. One divergence: the tag line came out nearer half the headline's size than the quarter the ratio asks for, so there are three sizes but not at 8 : 2 : 1.

One Family, Three Sizes

Produce ONE image, 2:3 portrait: a full-bleed photograph with a type system over it. Follow every line. Replace only the FIELDS block; everything after it is fixed.

First — do you have the fields?

If any field below still has braces around it, stop and ask. Put all the questions in one short message, and show the example under each one so they can see the shape of a useful answer. Wait for the replies, then draw. Never fill a brace yourself: a value you invented is a value nobody asked for, and it will look exactly as considered as the ones they did give you.

Ask in whatever language they are writing to you in. Translate the questions and the examples; do not make someone read English to tell you what they want.

The examples are only examples. If someone answers a question, use their answer; never fall back to the example because you prefer it.

If the fields are already filled in, ignore this and carry on.

Fields — replace these five lines only

  • The photograph: {what it shows}
  • The headline: {a few words}
  • The supporting lines, and where each goes: {up to five lines, each with a position}
  • The family, and the two weights: {one typeface, and two weights}
  • The neutral, and the one accent: {a colour for all type — one accent, on one line}

The one-family law

Every piece of type on this poster comes from one family. The only permitted variation is weight and width within it.

  • No script face. No serif beside a sans. No second display face for the "special" line.
  • No outlined, shadowed, or effect type.
  • Capsules, rules and numerals use the same family as everything else.

A reference run of this style put six faces on one sheet: a heavy gothic headline, a bold condensed subhead, a light sans inside capsules, a small sans at the foot, a high-contrast italic script for one word, and a different sans again in the footer. Each was fine. Together they read as six people who had never met.

Count the faces before finishing. The answer is one.

The three-size law

Exactly three sizes, in a fixed ratio of roughly 8 : 2 : 1.

  1. The headline — the largest thing on the sheet by a long way.
  2. The middle size — one line only, usually the tag line or subtitle, at about a quarter of the headline.
  3. The small size — everything else, at about an eighth of the middle size.

Nothing sits between these. If a line feels like it wants to be between two sizes, it belongs at the smaller one.

Weight, not size, separates things within a size.

Colour

  • All type in one neutral — white or black, as the fields say, chosen so it holds against the photograph.
  • Exactly one accent, on exactly one line. Nothing else is coloured.
  • No gradients, no strokes, no drop shadows on type. If a line is not legible, move it somewhere quiet rather than adding a shadow.

Placement

Type goes where the photograph is quiet.

  • Find the largest low-detail region — sky, a wall, a road surface, a wash of shadow — and put the headline there.
  • Small lines sit in the margins, at consistent insets, aligned to each other across the sheet: the top pair share a baseline, the bottom pair share a baseline.
  • Nothing crosses a face, a sign, or the busiest passage of the picture.
  • No panel, box, scrim or gradient is added behind type to make it work.

The photograph

  • Full bleed, running off all four edges, no border and no frame.
  • One clear depth: something near, something far, and a direction to look in.
  • Warm or cool as it comes; unretouched, not stylised, no filter.
  • It is a photograph, not an illustration and not a render.

Words

Only the words the fields supply, spelled exactly as given.

  • No invented handles, hashtags, dates, issue numbers or rights lines.
  • If a string cannot be rendered cleanly at the size chosen, make it larger or drop it — never approximate the letterforms.
  • Every word on the sheet must be a real, correctly spelled word.

Never

  • ✕ more than one typeface family
  • ✕ a script or italic display face for one line
  • ✕ more than three sizes
  • ✕ more than one accent colour, or an accent on more than one line
  • ✕ shadows, strokes, outlines or glows on type
  • ✕ a scrim, box or gradient added behind type
  • ✕ type over the busiest part of the photograph
  • ✕ misspelled, garbled or approximated text
  • ✕ words the fields did not supply

The result

A poster where the photograph is doing the looking and the type is doing the telling: one voice, three volumes, one thing said in colour, and every small line sitting exactly where its opposite number sits.

The whole template, in one piece. The steps below are the entire workflow.

How to use it

  1. Copy the whole template with the button above.
  2. Replace the five FIELDS lines. Keep the supporting lines to five or fewer, and say where each goes.
  3. Paste it into any image-capable agent or model, in one message. One run returns the poster.
  4. Count the typefaces before shipping. If a script or a serif has appeared alongside the sans, the system broke.

Before it runs

  • A photograph with somewhere quiet in it. Type needs a low-detail region to sit in, and a photo that is busy edge to edge gives it nowhere.
  • Fewer lines than you think. Six pieces of information at three sizes is a system; ten is a noticeboard.
  • One family with a real weight range. A face with only one weight cannot build a hierarchy without changing size, and size is already spoken for.

When to reach for it

Exhibitions, city campaigns, festival programmes, editorial covers — anywhere a good photograph has to carry information. Templates in this style return six typefaces on one sheet: a heavy gothic headline, a condensed subhead, capsules in a light sans, a high-contrast italic script, and a footer in something else again.

What changes

  • One full-bleed photograph with a complete type system laid over it.
  • Every word from one family, varying only by weight and width — no script, no second display face.
  • Exactly three sizes, set by ratio rather than by eye, so the hierarchy is decided rather than negotiated.
  • One accent colour on one line, with everything else in a single neutral.
  • Type placed in the photograph's quiet regions, and never over its busiest passage.
