Every statistic you have read about how long investors spend on a pitch deck is an average. That sounds like a technicality. It isn't. On this kind of data the average and the experience of a typical reader sit so far apart that designing around the average means designing for a reader who mostly doesn't exist.
New platform data from The State of Fundraising 2026 puts the average viewing session on a pitch deck at 126 seconds, and the median at 66. Both come from the same 38,830 opens. Only one tells you what happens to most decks.
How long do investors spend on a pitch deck?
The average investor session on a pitch deck runs between 100 and 145 seconds, depending on whose data you read. The median is roughly half that. Most decks get under 70 seconds of attention, while a small number get five minutes or more and pull the average upward.
The most widely cited figures come from DocSend, whose published data put average seed-stage read time just under two minutes and pre-seed a little above it, both falling year on year. Pitchwise's own platform data lands at 126 seconds, close to the middle of that range, measured across an entirely different user base.
Two independent platforms landing that close together means the number is real. It just isn't the number you should design against.
Why the average is the wrong number
Session-length data is heavily right-skewed. Most people glance. A few leave the tab open while they take a call. Those few drag the mean upward, and the mean stops describing anyone in particular.
From the same dataset:
- Average (mean) session: 126 seconds
- Median session: 66 seconds
- Ratio: 1.9 times
Half of everyone who opened a deck was gone within a minute and six seconds. The average was two minutes. Same data, one number nearly twice the other.
This is why two credible reports can publish very different figures and both be right. One is reporting a mean, the other a median. The full methodology behind these numbers is published alongside the report for exactly that reason.
What 66 seconds actually buys you
Most guidance lands on 10 to 15 slides. Guy Kawasaki's 10/20/30 rule is the origin of much of it, and more recent analysis broadly agrees.
At 12 slides and 66 seconds, that is five and a half seconds per slide. Nobody reads at five and a half seconds per slide. What actually happens is that a reader spends twenty or thirty seconds on the first two slides, decides, then either scrolls fast or stops.
The practical consequence: slides eight through twelve are not where your deck gets decided. They exist to survive the second read, not to win the first.
How to design a pitch deck for a 66-second read
Designing for the average and designing for the median produce different decks:

Put the conclusion on slide one
Not the problem. Not the market size. The thing you want remembered if they read nothing else. If a reader closes the file after fifteen seconds, slide one is the entire impression.
Write headlines that are findings, not labels
“Traction” is a label. “Revenue tripled in nine months without a sales team” is a finding. A reader skimming at speed reads headlines and little else, so a deck whose headlines read as a sentence-by-sentence argument survives skimming. Our pitch deck templates are built around that structure.
Make the ask findable without reading
How much you are raising, at what stage, and what it buys should be locatable in under five seconds. Many decks bury this on the final slide, which assumes the reader gets there. Half of them don't. A use of funds breakdown belongs early, not in an appendix.
Cut every slide you cannot defend
If a slide would not change an investor's mind, it is costing you seconds you have already been shown you don't have. Detail that matters but doesn't fit, such as a full cap table or a runway model, belongs in a data room rather than in the deck.
Design for a phone, at speed, without sound
Decks get opened on phones between meetings. Small type, dense tables and low-contrast charts fail under those conditions. If a slide cannot be understood at a glance on a small screen, it will not be understood at all.
The second read is the one that matters
The same dataset shows the average visitor accounts for 2.7 views of a deck. Decks are not opened once and closed, and the ones that work get returned to, often by a different person at the same firm. Once a deck moves inside a fund, a data room checklist matters more than another slide.
That reframes the job of the first 66 seconds. It is not to close anyone. It is to earn the second open, and the forward to a colleague. A deck optimised to be understood quickly gets forwarded. A deck optimised to be comprehensive gets closed.
Frequently asked questions
How long do investors actually spend on a pitch deck?
Published averages cluster between roughly 100 and 145 seconds. The median is considerably lower, at 66 seconds in the most recent platform data, because a small number of long sessions pull the average up. Assume about a minute of real attention on a first read.
How many slides should a pitch deck be?
Most guidance lands on 10 to 15 slides for pre-seed through Series A. Pre-seed decks tend to work at 10 to 12, seed at 12 to 15. The count matters less than whether every slide earns its place, because the reader is unlikely to reach the end of either version on a first pass.
Does a shorter pitch deck get read more thoroughly?
Not automatically. A short deck with no argument loses a reader faster than a longer one that builds a case. What shortness buys you is a higher chance that the slides you care about are among the ones actually seen. The reliable lever is ordering, not length.
What should be on the first slide of a pitch deck?
The single sentence you want remembered, meaning what the company does and why it matters now, plus enough context that a forwarded copy makes sense without you in the room. Treat slide one as though it is the only slide that will be read, because for a meaningful share of readers it is.
How can I tell whether investors are actually reading my deck?
You cannot tell from an email attachment, which is most of the problem. Sharing a deck as a tracked link shows who opened it, when, for how long, and whether it was forwarded. That visibility is what the data in this article is built from.
The number to design against
Two minutes is the flattering version. Sixty-six seconds is the honest one, and it is the number your deck is competing against.
