750/72 = 10.4 inches, or 26.4 cm is what is important to you?
I've been asking myself that for a few posts...P.S. Has this thread gone far enough off topic yet to qualify for a thread split?
Ha. Well, that's one way to look at it I suppose. Another is that I am open to good ideas, even if the source is of questionable sanity.
When I was running vB it always had a fluid width, but like some others here, my browser window is never maximized (except on the laptop), so it was always "fixed" for me. But honestly, after using the new layout for a few days I didn't like the fixed width, and my good friend here kept pointing out that it was simple to add the option, so I did. She was right about that.
Unless, of course, there are things like this in the posts:
Pot, kettle, etc.
As you know we were not talking about sigs, that is a completely different thing.hmmmmm..... scratching one idea off my list.
From a functionality viewpoint, with smaller avatars, the horizontal post bit (user details from left to right between each post) frees up a bunch of screen width for pictures - and that screen width is very precious to us. We have many many pictures on our forum.
But with the larger avatars, I don't think horizontal post bit will work with xf. Especially when xf hides the user details on the left by default so it does not leave a large amount of wasted vertical space.
Xenforo scales the images perfectly so no need to worry about that.
You can set it that way if you want to after I hand you the keys ............. if you must. 
Kim, I don't know if your opinion changed in those 2 and a half years, but as a designer you should very well know there are good reasons for a fixed width forum, of some which has been addressed here. Many forums today aren't just plain forums, but have some sort of an article section, either integrated with a CMS or a native solution, like XenPorta. You can't have a fluid style in those sections. And you can't have a fixed style for the article section and a fluid style for the forum, because this would be bad design. And regardless of an article section, as Kier said text in fixed width blocks looks generally better.Why do I detest fixed width? Two reasons...
One - I feel completely hemmed in and claustrophobic having to use fixed width skins, I refuse to do it in fact, for example: There is an excellent Admin forum around, even though it is a fine site with good people and discussions.. I cannot abide fixed width skins, truly physically feel sick using them, and whilst that site several choices in themes, they are all fixed width, sadly I cannot post there at all. Some people have said to me that they cannot read great big long strings of text, well I cannot read great big horizontal blocks of text.... different mindsets, left/right brain differences.. I'm a retard, who knows, but I do know I am not alone, with 8 years of providing skins to boards of all levels I have only twice done Fixed width Custom Skins, and I detested every minute of doing them. I have had this discussion with many many people over the years, and lots feel the same way.
.... And Two... it is often control freakiness of the highest order.. dictating what width people will read forums is imho the Admin Nazi-est move out there... if I want 1920px wide text, surely that is my business.... and the argument you don't want to "maintain" two styles is (naturally) spurious... make the default xenforo style available (which is nicely fluid you will notice) then you don't have to do a single thing.. And then, those of your pooor members who like me detest being dictated to in such a fundamental way will have one less control freak thing to object to
It costs you nothing, it delivers choice, and everyone is surely a winner.
