A slide projected in a room carries about thirty words, because a listener can't read and listen at once and the speaker is the channel. A board page carries about 190 words plus its exhibit, roughly six times as much. Why so much more? Nobody is speaking while it's read. Directors read the pack alone, before the meeting, at reading speed. Size a read page like a projected slide and you get a sixty-page pack that says nothing. It's the commonest board-deck failure, and the one that looks most like good practice.
Do the arithmetic once and the design targets follow. At 190 words a page and 240 words a minute of silent reading, fourteen body pages take 14 × 190 / 240 = 11.08 minutes to read. Design against that number, because it's the one you can ask a director to commit to. A board meeting of 120 minutes that gives half its time to three decisions gives 20.00 minutes per decision. A director who has spent eleven minutes reading arrives ready to spend those twenty minutes on judgement, with the comprehension already done.

What makes a dense page readable?
Density isn't licence to crowd. Four properties make a dense page readable, and they're the difference between 190 words that work and 190 words that repel.
The title carries the claim, in a sentence with a verb, and the body only makes the title believable. "Contribution fell ₹0.27 crore on revenue up ₹12.80 crore because two cost lines moved 5.6 points against us" is a page title. "Q2 FY27 Margin Analysis" is a filing label.
The exhibit answers a single question, and the reader can see which. A page with two charts is usually two pages stapled together to save a page count nobody was measuring.
The prose is in complete sentences. A director reading alone can process a sentence faster than a bullet, because a bullet withholds the verb and makes the reader supply the relationship. "Trade spend up" leaves the reader guessing whether that's cause, effect or plan. "Quick-commerce trade spend cost us 2.5 points of contribution margin, up from 0.9 a year ago" doesn't.
And the page states its source and its date, in small type at the foot. A director checking a figure at 11pm on a Sunday will either find the source line or stop trusting the number. There's no third outcome.
Why does a dense pack need an indexed appendix?
The appendix is what makes the density sustainable. Forty-one appendix pages behind fourteen body pages isn't a failure of editing, as long as the appendix is indexed and each body page names the appendix page that supports it. Think of the appendix as a contract. Each body page makes a claim, and the appendix page behind it is where a director who doubts it goes. Body pages are 25.45% of the rebuilt pack, which is roughly right for a quarterly pack in a company with real operating complexity.
