But he's been saying that 1) the analogies between fixed width and other
dumb popular things are not good analogies; while I think they're over the
top, they're not really poor analogies in that just because something is
trendy does not make it good... 2) people here are in denial that some
people think they prefer this look; there's no evidence I can find to
support that.
This isn't so much a response to Neal as it is to the whole thread in
general. I've just isolated the above quote so it provides some context to
what I am about to say.
First, we must understand one thing - "evidence" is very hard to come by in
the usability world - especially evidence that will hold up to scientific
scrutiny. This is because there's hardly any quantitative research being
done in human-computer interaction (at least as it relates to the Web).
Everything in the usability world is what I like to call "Informed
Conjecture".
My company does usability testing for large gov't agencies and Fortune 200
companies. We almost never test more than 12 people for any single task[1].
The reason is simple: by 3 people, we've uncovered what we think will be a
problem. By 6 people, we've pretty much uncovered all of the problems. By 8
people, we've solidified the biggest problems and by 10-12 people, we've
filtered out the upper and lower people in the curve. *Usually* persons
9-12 aren't going to tell us anything we don't already know. So for us to
test more than 12 people would be a major waste of our clients' money and
our time. Results are what matter to clients, not whether we've
contributed to the global wealth of knowledge - especially when each
situation really is unique. Website interfaces are so different that what
creates a problem on one site might not create a problem on another (because
other things might be so good on the second site that the "problem" is
minimized).
Now, let me give some of my "informed conjecture" on this topic:
Whether or not the site is fixed or liquid is not the [whole] issue. The
issue is "what benefits does a liquid design have over a fixed?"
I have not noticed any user preference for fixed vs. liquid layouts[2]. This
is for two reasons: a) as others have pointed out, they're all too stupid to
know the difference and b) because the majority of people are using 1024x768
or lower resolutions. So the whole "preference" thing flies out the window.
People don't know and moreover, they don't care.
But here's where the big difference comes in. The mantra at my company is -
If the user cannot find it, then it must not exist; if they cannot use it,
then it must be broken. A fluid design can make the difference between
whether a user finds the info or misses it completely. This is due in no
small part to the fact that content "below the fold" is often not noticed by
users. While most designers are at least smart enough not to cause
horizontal scroll, they've got no qualms about causing vertical scrolling.
To them, adhering to some misguided goal toward an "image-safe" size of 800
pixels is all they care about.
If anything, the issue of fixed vs. liquid layouts is one of scanability.
The reason why people miss the content below the fold is because they don't
actually read what is on the screen. They're scanning for keywords and
phrases which indicate whether or not the page their viewing has the content
they're after. If the content is below the fold, it may as well not
exist.[3]
What does this have to do with fixed vs. liquid? Designing a fluid site
means that you're increasing the chances that people on larger monitors
(60%+, depending on source) will be able to scan your content[4]. You're
presenting them with more content above the fold and therefore enabling them
to scan more text to find what they're looking for. This is especially
useful for the users on 1024x768 monitors who are likely to be browsing
full-size as well as people on 1280 wide monitors who are often browsing at
close-to full size[5]. That increased width (200 & 400 pixels,
respectively) can make a HUGE difference in whether or not people can
actually find the information they're after.
Choosing a liquid layout seems to be a no-brainer as far as I am concerned.
About 36% of the population is surfing the Web with 800x600 resolution.
You'd be a fool not to accomodate them. At the same time, you're a fool not
to accomodate your users on larger monitors as well, since they account for
the majority of your potential traffic. Remember, unless it is a pr0n
website, nobody's comin to the site for the pictures, they're coming for the
content, so give it to them!
1 - A "task" being a single interaction, such as registering for an online
newsletter or finding a bit of information on a specific topic
2 - Actually, one person did make a comment during the last test that "I
hate all that white space on the right. They should make it fit the screen"
3 - Unless you're smart and make sure it is clear that the page content
continues.
4 - Assuming, of course, that their browser window is full-size
5 - This claim is based solely on my observation in the lab, not
quantitative data
