What about your forum? Should you change that setting? How many posts per page should you have and why?
Additionally, on mobile devices, shorter pages are usually preferred to long ones.
The only downside? Your visitors will have to click Next Page more often in order to read all of your content. Not a major issue in my opinion.
10 posts per page is pretty much the minimum you can go, otherwise it would look silly. Ever seen a forum showing 5 posts per page? Me neither.
15 – 20 Posts Per PageThis is the average. It’s a good fit between short and long pages. Like I said earlier, XenForo defaults to 20, vBulletin at 15. If you don’t have any special reason to change it, stick to it.
20 + Posts Per PageI don’t think that forums with such a higher number of posts per page (30 for instance) are that common right now. Not because it can’t be done, but because there’s no point in fitting that many posts in a single page.
