Measured across 3,243 videos as of 1 Sep 2026 6 min read
The sponsor read is the most disliked minute on YouTube and it has an entire ecosystem of tools built to remove it. So it is worth knowing how much of your time it is actually taking: across 3,243 measured videos, sponsor reads come to 1.6% of the runtime. The share of runtime that restates, recaps or sets up rather than adds is 40%.
1:07 Median length of the sponsor read in a video that carries one. 699 of 3,243 measured videos carry one at all. 1 September 2026.
A note on the numbers. Unlike the rest of this site, the figures on this page are frozen at the date above rather than recalculated on each visit. A report people cite should not move under them. When we run this measurement again it will be published as a new edition with a new date.
One video in five, about a minute each
We read every measured video in sections and label what each one is doing, which means a sponsor read is a thing we can count rather than estimate.
| Measure | Across the 699 videos that carry one |
|---|---|
| Sponsor seconds in the video (median) | 1:07 |
| Sponsor seconds in the video (mean) | 1:16 |
| Share of that video's runtime (lower quartile) | 3.8% |
| Share of that video's runtime (median) | 6.6% |
| Share of that video's runtime (upper quartile) | 11.0% |
| Share of that video's runtime (worst in the library) | 60.9% |
Only videos carrying at least one sponsor read. Across the whole library, sponsor reads come to 53,192 seconds of 3,356,077 — 1.6% of all measured runtime.
699 of 3,243 videos carry at least one — 21.6%. In those videos the median sponsor read runs 1 minute 7 seconds and takes 6.6% of the runtime. Three quarters of them stay under 11%. The single worst case in the library gives 60.9% of its runtime to a sponsor, which is a real thing that exists and is also one video out of 3,243.
The four videos in five with no sponsor read at all are the part of this that gets least attention. Whatever is making a typical video feel longer than it needs to be, it cannot be the sponsor segment, because most videos do not have one.
Where sponsorship concentrates
It is not spread evenly, and the pattern is close to what you would guess from who has something to sell to that audience.
Tech news leads at 38.7%, engineering and hands-on making follow at 37.9%. At the other end, comedy sits at 4.0% and nutrition at 10.3%. Subjects where the viewer is already in a buying frame of mind carry more sponsorship than subjects where they are not, which is unsurprising and worth stating because it is the one part of this measurement that behaves exactly as expected.
Read the ends of that chart rather than the middle. Several of those subjects rest on fewer than a hundred videos, and a five-point difference between two neighbouring bars is not a finding.
Sponsored videos are slightly worse, and the sponsor read is not why
Here is the result that complicates the headline, and we are not going to bury it.
| Runtime | Videos with a sponsor read | Their padding | Videos without | Their padding |
|---|---|---|---|---|
| Under 10 min | 121 | 49.8% | 1,063 | 44.4% |
| 10–20 min | 298 | 42.4% | 780 | 39.8% |
| 20–30 min | 144 | 40.4% | 275 | 37.0% |
| 30 min and over | 136 | 37.2% | 426 | 35.9% |
Split by runtime because sponsored videos are longer on average — 22:53 against 18:23 — and padding falls with length, so an uncontrolled comparison would flatter them.
Sponsored videos are longer than unsponsored ones — 22:53 against 18:23 on average — and padding falls with length, so a naive comparison would make sponsorship look harmless. Split by runtime band and the gap appears in all four: sponsored videos carry between 1.3 and 5.4 points more padding than unsponsored videos of the same length. On measured value the two groups are within a point of each other everywhere except the twenty-to-thirty-minute band.
So there is a small, consistent association between carrying a sponsor and being slightly more padded. What there is not is a mechanism running through the sponsor read itself, because the arithmetic does not work: a 6.6% sponsor read cannot produce a 5.4-point padding gap, and the padding measurement counts restatement and setup, not advertising.
The reasonable reading is that both are downstream of the same thing. A video built to be sponsorable is a video built to a length and a format, and the format is where the restating lives. That is a hypothesis about production, not a result, and we are labelling it as one.
The comparison that matters
Put the two numbers side by side on a twenty-minute video that has a sponsor read.
The sponsor read costs you about eighty seconds. The padding costs you about eight minutes. One of those has a browser extension devoted to removing it and a widely shared sense of grievance attached; the other is six times larger, sits inside the body of the video where no section boundary marks it, and is mostly invisible until you are already twelve minutes in.
That is not an argument against skipping sponsor reads. Skip them — it is a free minute, and on the one video in five that has one it is the easiest minute you will ever recover. It is an argument that the minute is not the problem, and that a tool which removes it has solved the small half of the question while leaving the large half exactly where it was.
What this measurement does not say
It is not an ethical judgement of sponsorship. We measure how much runtime a sponsor read takes and how the video around it scores. Whether a disclosure was adequate, whether the product is any good, and whether the arrangement changed what the video says are all questions this measurement does not touch.
A sponsored video is not a worse video. The gap in the table above is small enough that it tells you nothing useful about any single video, and value scores are essentially identical between the two groups. Nothing here supports avoiding a video because it has a sponsor.
We do not identify sponsors or name videos. Every figure on this page is an aggregate over the library.
How this was measured, and what it does not say
Each measured video is read in sections, and each section carries a label for what it is doing — the body of the video, an opening, a closing, a digression, an ask to subscribe, or a sponsor read. The counts here are over 46,105 sections in 3,243 videos, totalling 3,356,077 seconds of runtime. The reading is ours. Method and its limits are in what value density means.
The padding figures cover 3,002 videos, not 3,243. Padding is only measured on explanatory and instructional material; the entertainment, news and ambient videos in the library are scored on everything else and carry no padding figure.
A very short sponsor mention may not be counted. A section is a stretch of runtime, so a two-second brand name inside a sentence is part of the body rather than a sponsor read of its own. The count is of segments, not of mentions.
The sample is not YouTube. It is English-language explanatory video across twenty subjects, assembled to build a recommendation library rather than to be representative of the platform. A library built around, say, product reviews would carry far more sponsorship than this one.
The figures are frozen at 1 September 2026. Scores are recalculated as the underlying measurement improves, so the live numbers on the shelves will already have moved slightly from these. This edition will not be edited; the next measurement will be published separately.
Questions people ask
How long is a typical YouTube sponsor segment?
In this library the median video carrying one gives it 1 minute 7 seconds, and 6.6% of its runtime. Across the whole library, sponsor reads account for 1.6% of all measured runtime.
How many YouTube videos have sponsors?
699 of the 3,243 measured videos — 21.6% — carry at least one sponsor read. It varies a lot by subject: 38.7% in tech news against 4.0% in comedy.
Are sponsored videos worse?
Barely, and not in the way people expect. Sponsored videos carry between 1.3 and 5.4 points more padding than unsponsored videos of the same length, and score within a point of them on measured value. The sponsor read itself is not what accounts for the gap — it is too small.
Is skipping sponsor segments worth doing?
It recovers about a minute on the one video in five that has one. That is a real minute and worth taking. It is not the same order of saving as knowing which videos not to open, which is what the 40% padding figure is about.
Is this the whole of YouTube?
No. It is 3,243 English-language explanatory videos across twenty subjects, assembled to build a recommendation library rather than to be representative of the platform.
