Pitch decks encodes values as one idea per slide; a chart only if it is the sentence. Sequoia/a16z memo culture plus Keynote-era startup theatre.
In reports, ads and assignments it fits fundraising, sales kickoffs, grant talks, competition finals. Skip it when dumping the whole dashboard — a deck is a speech, not a warehouse.
Rules
- Rules 1 — Use one idea per slide; a chart only if it is the sentence as one channel, not two.
- Rules 2 — Direct labels beat a distant legend.
- Rules 3 — Do not hide zero. If you break the axis, say so.
- Rules 4 — Colour encodes category or magnitude, not both.
- Rules 5 — Put the claim in the title, not just “Pitch decks”.
- Rules 6 — Source and period, even in small type.
Palette
- Palette 1 — Categories: distinct hues. Sequences: one hue, changing value.
- Palette 2 — Diverging: a neutral centre, emphasis at both ends.
- Palette 3 — One brand colour plus greys beats a rainbow.
- Palette 4 — Check contrast on a projector and in greyscale print.
Type
- Type 1 — Tabular figures for numbers. Do not pour body copy into the chart.
- Type 2 — Titles as sentences; axes as short nouns.
- Type 3 — For CJK, drop weight one step and leave tracking.
Pitch decks: honour one idea per slide; a chart only if it is the sentence, and switch when dumping the whole dashboard — a deck is a speech, not a warehouse.
