Scrolling to Read Text
Many people cannot effectively read text that requires horizontal scrolling, or scrolling up to get from one column to the next. People with low vision, dyslexia, and others who increase text size to make it readable (as introduced in Text Customization for Readability) often have to deal with text that requires scrolling.
Sometimes when text size is increased — especially with zoom functionality, lines of text go beyond the visible window (or viewport) and people have to scroll back and forth horizontally to read the text. Sometimes when text is increase that is in set columns — such as newsletters and scientific papers in PDF, people have to scroll up several times to get from the bottom of one column to the top of the next column.
For most people (even without disabilities) it is harder to read when they have to scroll horizontally or between columns to read sentences. For some people with disabilities, it is impossible to adequately read and comprehend text that requires such scrolling. Finding and activating scrollbars, then finding the next words in the sentence requires more effort. This causes a lose of reading flow and degrades comprehension, especially for people who have general difficulties understanding written text.
Below are perspectives on the importance of not having to scroll to read text.

Horizontal scrolling for others
Question:
How important is it to be able to change the following:...
No horizontal scrolling
(change it so that they do not have to scroll to the right to read a line of text; instead, text wraps to the next line without requiring scrolling; sometimes called rewrap)

- I can't do this very easily so i usually cut and paste it so I don't have to.
- Having to scroll is very distracting at times, especially to someone who is dyslexic and also has MD. I lose the line, or concentrate on getting the cursor on the scroll and lose the line. I have one good eye to read with...and I hate having to go back and find myself !
- That's just awful! Don't do it!!! I give up, disgusted with the author/web content person's poor design or plannning!
- If I have to scroll right and left as well as up and down, I won't read the page.
- It's tedious to have to scroll for every line and I generally quit.
- I hate reading when I have to scroll right or left.
- If I constantly be moving the document to read, I will either lose my place or make harder to understand.
- If lots of text I tend to lose my place if I have to scroll left & right.
- prevents confusion and missed items
- Super important. Horizontal scrolling gets very annoying.
- This is a problem, if my vision gets worse I'll need to magnify or zoom more and scroll more. It is slower and harder to do for ease of reading.
- Mainly on a frustration perspective. I can do it but hate it with a passion.
- Yes! This is really important - I *hate* having to scroll left and right and left and right constantly :)
- Text wrapping is significantly better than horizontal scrolling.
- otherwise it is disorienting.
- I hate when I'm reading something, and I have to go to the bottom of the page in order to find the scrolling arrows. Sometimes, using the arrow keys doesn't work, and it's difficult to navigate this task and maintain my place in the text. If I'm interpreting this correctly, I think it would be very important to have the choice, especially for those who are using other accessibility programs.
- It slows me down having to scroll to the right and then to the left in order to read the text which is "covered".
- I hate right scrolling whiplash
- especially when browsing on my mobile. It is a pain!
- Scrolling is too confusing
- Very important and very dependent on context for appropriate application to improve ease of use rather than degrading it.
- Makes it easier to read
- The smaller the device, the more important this is.
- older people..some..prefer no scrolling at al
- Critical. See above.
Reflow to avoid scrolling from the bottom of one column to the top of the next column
Question:
How important is it to be able to change the following:...
Text in one continuous block, instead of in multiple columns
(change it so that [they/you] do not have to go from the bottom of one column up to the top of another column to read text; e.g., changing text from 3 columns to 1 column; sometimes called reflow)
Note: Overall responses are not included here because several respondents answered based on different aspects of columns, such as line length: "I like it when the text is in colems because I don't have a big long line to read. Instead the lines are short." and "My eyes get tired and i lose my place if the text is not broken up". The comments below illustrate that reflow from multiple columns into one is important for some users.
Comments
- I loose track of what is being said by time I scroll back to top
- I get frustrated sometimes as I lose my place now when I am reading and have to jump columns.
- I find it easier to read wide blocks of text, rather than columns. This minimizes the visual return which is one of the most difficult visual tasks for me.
- Columns often get tricky if you try enlarging the text size. One column makes things much easier and also means that you don't need to keep jumping from one place to another. Also if I am reading something long, it's so much easier to have the text displayed large enough to read without magnification, so that it wraps to screen properly - whereas with a screen magnifier you invariably have to keep moving the focus left to right to left to right.
- If newsletter is displayed in columns like that then I often give up on reading it if I can't change it
- With my MD it is easier to follow in one column. With my dyslexia, on the computer, I sometimes have trouble getting back up to the other column..
- It's extremely irritating to have to scroll the document up/down sideways (when reading on a mobile/tab). Multicolumn is a concept carried forward from the paper days
- I hate multiple column e-newsletters!
- With field defects it's hard to follow text S you describe.
- This would be nice but I usually don't know how to do it
- I think this is obvious as a usability issue one does not want to scroll up and down the page due to multiple columns.
- As a general rule, I believe that using multiple columns on a website - or any document used online - is poor design. This requires the user to scroll up and down repeatedly. This is even more challenging if the user is editing the document - for example, in Microsoft Word.
- Could be important, as scrolling down to the bottom, you lose your train of thought by the time to scroll back to the top.
- Some people will miss the other columns
- I know that some people I work with find columns confusing and/or distracting.
- Text in more columns is confusing.
- prevents confusion
- Flowing text is often an issue - particularly semantically where a phrase or sentence is split
- reflow helps as much magnified text needs all the screen
- My clients hate columns.
- Depending on viewing conditions this can be very important (preventing scrolling, having a clear expectation of the flow, not missing content)
- Especially bad if the user ends up having to constantly scroll up and down. I have observed that users often lose their place easily in this situation.
Horizontal scrolling with screen magnification software
The survey did not ask about screen magnification software and horizontral scrolling; however, several respondents included comments.
Comments
You:
- I am currently using Zoomtext at 4x magnification and moving the screen back and forth to read a long sentence makes me nauseous/sea-sick.
- I am not comfortable with Zoom because the text scoots from one side of the screen to the other, leaving me frustrated.
- All applications should allow the user to adjust the point size. This reduces the left to right movement required when using screen magnification software.
- I wish screen magnifiers could automatically "word wrap" text based on the degree of magnification selected so that the user does not have to move the viewing window from side to side when reading, e.g. Doc Reader feature in ZoomText
- Magnification disorients me and makes it worse. I use very large print and zoom in with web browsers instead.
- I feel the magnification software is very uncomfortable. I'd rather make the text bigger.
- If I am reading something long, it's so much easier to have the text displayed large enough to read without magnification, so that it wraps to screen properly - whereas with a screen magnifier you invariably have to keep moving the focus left to right to left to right.
Others:
- People who use screen magnification I've user-tested sites with have been very much hindered by having to horizontally scroll in magnified views
- When using an enlargement software such as ZOOMTEXT it increase everything including the space so kids have to scroll all over the screen to find their information.

But for people who need just a little bit of zoom, I suspect that horizontal scrolling is the number one reason they give up, revert to non-zoom (maybe permanently), and kill a lot of trees by printing web sites and emails.
