If they can read your slide, they stopped listening: how many words per slide in a pitch deck

Sunny Ray · Apr 19, 2026 · 6 min read

Six to ten words per slide. Thirty-point font or bigger. That is the rule I gave a founder on April 15, and he got it faster than most.

He used to be a teacher. He had spoken at education conferences, where slides carry the content and the audience takes notes. Then he saw the deck we rebuilt for him and told me the style was completely different from anything he was used to. It was a quick shift in mindset, he said, and now he could see why investor decks look the way they do.

So here is the answer to the search, plainly: put six to ten words on a slide, use 30-point type or larger, and move every detail into a one-pager you send after the meeting. If an investor can read your slide, they stopped listening to you.

The deck is a placeholder for you

People cannot read and listen at the same time. Put a paragraph on the screen and the room goes quiet in the wrong way. Every eye is on the wall, every brain is parsing your sentence, and the founder standing next to it has become background noise.

That is a bad trade, because you are the asset. The investor is not buying the slide. They are deciding whether to spend the next ten years in business with the person talking. The deck is a placeholder: a headline that tells them what you are about to say, so they can give you their full attention while you say it.

The other reason is the one founders resist most. People do not act on logic. They act on emotion, then back it up with logic. An investor will want the numbers, and they will get them. But in the five or ten minutes you have, your job is to make them feel something. Would we be proud to see our name next to this on the front page? A wall of text never made anyone feel that.

Six to ten words, 30-point font

The public version of this rule is Guy Kawasaki's 10/20/30, from 2005: ten slides, twenty minutes, nothing smaller than 30-point type. The font floor is the clever part. At 30 points you physically cannot fit a paragraph on a slide, so the rule enforces itself.

I go one step further and cap the words. Six to ten words forces you to decide what the slide is for. Not "Our Market Opportunity" followed by four bullets, but one line that makes a claim, like a newspaper headline. If you need a sentence of explanation, that sentence comes out of your mouth.

A good test: show each slide to someone for three seconds. If they cannot tell you the point, the slide has too many words or no point at all.

Which three things the words should carry

Short slides only work if they carry the right things, in the right order. I have raised over $100 million across my companies, starting with the first Bitcoin exchange in India in 2013, and the best investors I have met all ask themselves the same three questions, in this order.

First, how big can this get? Market size is the gating question and, in my experience, it carries most of the weight, something like 70% of the decision. These are people trying to add zeros, not make a few million, so the number goes near the top.

Second, can this thing take a real share of that market? This is traction, and investors want a movie, not a picture. One customer, then two, then five, then twenty a month. Data points across time that say rocket ship.

Third, why you? The team question, married to defensibility. Why can't a giant company copy this tomorrow, and what do you know because you spent five or ten years somewhere others didn't?

Three questions. Each one deserves a slide with a single claim on it. For my former teacher, the why-you slide writes itself: years inside classrooms give him insight into kids and coaches that no outsider has.

Send the detail after, in a one-pager

None of this means investors do not want depth. They do. They just do not want it on the wall while you talk.

So split the jobs. The deck is for the room. A detailed one-pager, or a longer written memo, is for after. Send it once the meeting ends, when they are alone with it and can read at their own pace.

I saw a sharp argument making the rounds this month that a detailed written memo beats a pitch deck for serious investors. I half agree. The memo wins for the reading. It loses for the room. If you walk into a meeting and present a memo, you have the same problem as the dense deck: they read, they stop listening. Use both, in order. Short deck live, deep document after.

Founders worry the short deck makes them look less prepared. It is the opposite. Anyone can paste a business plan onto 20 slides. It takes real clarity to say your company in six words.

Where founders get this wrong

The most common mistake is sending the presentation deck ahead of the meeting and expecting it to stand alone. A six-word slide with no speaker is a riddle. If someone asks for a deck before you meet, send the one-pager, or a reading version with the explanation written in, and keep the short deck for the room.

The second mistake is decoration. Slides crammed with logos, charts with twelve series, a team page listing every degree. Investors do not care where you went to school as much as you think. They care about the three questions.

The third is apologizing for brevity. Don't. Short slides signal confidence. Long ones signal that you are not sure which part matters.

The founder from April 15 walked away with a rebuilt deck, the three questions, and a plan to send the detail after. If you would rather pitch in rooms where investors already know you, the easiest room to own is your own show. Here is how we use it to raise capital.
