That is a Youtube streaming option the screen of youtube that you can revert to default size. Did you click on the video to see those options on the lower right corner and hover the mouse to choose the right actions.

I want to change YouTube tiles back to the smaller size. Cant figure out how to do it. I don't want the radical change of the extension you recommend.

Hi Scott, I'm curious what extension was recommended to you since it appears this is your first post here.

Also, are you only looking to fix the home page, or has YouTube changed in other areas?

Thanks, Mark, for looking into this so quickly. I'm not sure we are on the same page with my problem. The screenshot I submitted was from the home page. Each video suggested used to be displayed in a row of 6, but now only in a row of 3 bigger ones. (Smaller tiles also let you see down onto more rows and check out more of what you may want to see.)

If you were referring to the B & W buttons lower RT on each video (Auto-play, CC, Settings, Theater View, Full Screen, Mini-player) - None of them impact how that home page displays, unless there is another spot I'm not seeing. (I use these all the time watching videos.)

So it is a Home Page problem, and I was hoping you could help me get it to default back! I can actually see the old Mask of 6-Across briefly before the new one with only 3-Across drops in over the top.

thanks again - hoping you have another idea! -Scott

Answer to jscher about which extension YouTube recommended, that I thumbnailed and did not like for various reasons: Improve Your Tube, by code-for-charity

You can force more thumbnails per row by injecting some style rules into the page. As an example:

/* 6 regular videos per row */
div#contents.ytd-rich-grid-renderer {
  --ytd-rich-grid-items-per-row: 6 !important;
}
/* 10 shorts or 8 playables per row */
div#contents.ytd-rich-shelf-renderer {
  --ytd-rich-grid-slim-items-per-row: 10 !important;
  --ytd-rich-grid-items-per-row: 8 !important;
}
 

To test it, while viewing the YouTube home page, press Shift+F7 to open the Style Editors. Above the list in the left column, click the + button to create a new empty style sheet. On the right side, in the blank style sheet, paste the above rules. The thumbnails should resize immediately. You can adjust the values (6, 10, 8) to taste. Then copy/paste your personalized rule to a safe place (since reloading the page will flush it).

To apply custom style rules to a page automatically on every visit, I generally use the Stylus extension. However, if you use uBlock Origin, I've heard it also has a way to inject style rules (see this Reddit post). I don't know about that, but if you want to use Stylus, I can provide more information on that option.
