Font Size on News Homepages
Most news website homepages do not allow readers to adjust the font size of the page they are viewing. What you see is what you get. In part of the Eyetrack III testing, we designed two identical homepages and included overall font size as a variable. Half of our participants saw one homepage with larger type, the other half saw a homepage with smaller type. Homepage No. 4, below (click to enlarge), used smaller type.

EYETRACK III FINDINGS
This report is one of many from the Eyetrack III study of broadband-era news websites.

46 people were tested for one hour each in December 2003 by Eyetools Inc. in partnership with the Poynter Institute and the Estlow Center. During the test period, each test subject viewed mock news websites created for research purposes and real-world multimedia news features. Results were published in September 2004.

Homepage No. 9, below, used larger type.

Homepage No. 9 

This particular homepage design featured a mix of headlines with and without blurbs.


Finding: Smaller font size results in a little more careful viewing of the page.

Our other Eyetrack findings suggest that the overall size of type used on a homepage (both blurb text and headlines) has a marginally significant impact on viewing: On pages with smaller type, participants read more and were drawn into the blurbs. On pages with larger type, there's more scanning going on and less concentrated viewing (less reading) of the words.

Beyond statistical testing, researchers inspected the data for behavioral clues to help us decipher what might have accounted for the slight differences between the two pages. We observed on homepage No. 9 (large type) that more people spot-checked the page and looked at just the headlines, and then selected headlines on that basis alone. In contrast, we observed on homepage No. 4 (small type) that more people viewed the blurbs before clicking on a story, often reading them. Our confirmation of this theory came from two additional inspections that we conducted.

First, we speculated that people would read the blurbs more often on homepage No.4 (small type) than on No. 9 (larger type). We found that 88 percent of the group that looked at homepage No. 4 read blurbs at least once before clicking; 62 percent of the group that looked at homepage No. 9 read blurbs at least once.

To test that this affect was real, we confirmed that the inverse might also be true -- that more people would read only a headline on No. 9 than on No. 4. We found that 30 percent of the group on No. 9 clicked to article pages after reading only the headline without ever reading a blurb; that figure was 6 percent of the group on No. 4.

While this sample size is too small to claim that this tendency can be extrapolated to a general population, we found it interesting.

The heatmaps below for homepages No. 4 (small type) and 9 (large type) exhibit the visual patterns we saw. (A heatmap is an aggregate image showing overall eye activity on a webpage. Red-orange areas indicate the most eye activity, blue-black the least.) Click the images to enlarge.

Finding: Disparity in font size seems to make a difference between scanning and reading behavior.

Where viewing of text (especially blurbs) falls off is where there's a wide disparity between font sizes. The larger the headlines are in relation to blurbs the less likely it is that blurbs will be viewed or read. When headlines and blurbs are the same size, and that size is small, then both are viewed or read more often.

An interesting point -- brought out in our comparison of homepages No. 4 and 9 as well as elsewhere in our testing -- is that readers seem willing to make the effort to adjust their reading style to overcome whatever strain might be associated with use of smaller font sizes. With larger font size and especially larger headlines, people seem to be less likely to "work hard" in viewing content beyond the headline.

Eyetrack researchers surmise that once a person is focused on granular information that is not easily skimmed (i.e., small type), it is easier to continue in that mode to view whatever text might be close at hand (like a blurb).


Finding: Sometimes, content trumps format and presentation.

On homepage No. 9, the one with larger font size, the lower portion of the page was not read nearly as much as the lower portion of homepage No. 4, the smaller-font page. But, on No. 9 there was one story positioned low on the page that attracted a lot of interest: the headline "Craigslist: Now It's a Movie, Too."

Now, Craigslist is a San Francisco online institution, and Eyetrack III testing took place in San Francisco. It seems fair to believe that Craigslist has high recognition for many residents of the city. Participants in this study looked at the blurb heavily on this story -- on both the small-font page and the large-font page.


On the small-font homepage (No. 4), this heatmap detail shows high viewing rate for several article blurbs



On the large-font homepage (No. 9), the heatmap detail shows low viewing for article blurbs, except for the Craig's List story (largest orange area).

The way eyes found "Craig's List" is an example of how content can override the format of a page and its presentation. The people who mostly scanned the large-font page (No. 9) found this story of high interest to them, then zoomed in to look at the detail (the accompanying blurb).


Tips

Here are some tips based on what we found in this part of the research:

  • Is the intent with your website's homepage to encourage scanning or to encourage concentrated viewing? If you want your readers to fix their eyes on the homepage for longer, you might want to use smaller type in headlines and blurb copy. If you want to encourage scanning behavior, larger headlines may help.
  • If your desire is to have website readers examine all or most of the type on your homepage, you may want to keep headline size and blurb size comparable.
  • For pages using larger type and contrasting-size type, the words on a headline are important. With an audience that you know is scanning, the choice of words is critical.
