Want YouTube creators for your brand?

We find science channels that fit your brief, agree the price with each creator and track every video. You approve each step.

How this list is built

We searched YouTube in the US, the UK, Canada and Australia in October 2026. We ran 509 search terms and read the related videos of 1,213 channels we picked by hand. A channel is on this page when the search that found it was about science and its name, its description or our review of its videos matches the subject, or when we picked it by hand for this subject. We list the 40 largest by subscribers. Nothing here is paid for, and a place on the list is not a recommendation: it is the top of the list by size.

We leave out channels that belong to a company, a media brand, a game, a sports league or a shop, and channels that are not in English. Subscribers, views a video and videos in the last 30 days are the channel’s public figures on the day we found it. Views a video is the median of the channel’s last 15 long videos, or of its Shorts when it has posted no long video.

If your channel is listed and you want it changed or removed, email hello@sup.co and we’ll act on it fast.

FAQ

Frequently asked questions

These answers are worked out from the 40 channels shown above, so they change when the data does.

This page ranks 40 science channels from our searches of YouTube in the US, the UK, Canada and Australia. We found 55 with 50,000 or more subscribers, and list the 40 largest, ranked by subscribers. Our searches reach the channels YouTube showed for our search terms, so a big channel they did not reach can be missing.

The median channel on this page has 2.7M subscribers. Of the 40, 6 have 10 million subscribers or more, 24 have between 1 million and 10 million and 10 have fewer than 1 million.

Mark Rober (@markrober) has the most subscribers on this page, with 84M. It also gets the most views on a typical video here, at 27.4M. The median across the page is 610K views a video.

It is the median number of views on the channel's last 15 long videos, or on its Shorts when it has posted no long video. A median is the middle value, so one viral video does not lift it. On this page it runs from 5.1K to 27.4M. For a brand it is a better guide to what one sponsored video might reach than the subscriber count.

The median channel here posted 4 videos in the 30 days before we read it. 24 channels posted four or more, about one a week or more. 3 channels posted none in that time. A channel that posts often has more slots for a sponsor.

Of the 40 channels here, 15 give the US, 6 Canada, 5 the UK and 1 Australia as their country on YouTube, and 13 give no country. The country is a setting each channel chooses, so it says where the channel says it is from, not where its viewers live.

Sup runs creator campaigns for brands on YouTube, Instagram and TikTok. We find the channels that fit your brief, agree the price with each creator, handle the contract and the payment, and track every video. You approve each step. Request a demo and we will show you which channels fit your brief.
