What This Panel Does

Text Preferences is the first of the three buttons, marked AA. It controls how the words look: how big, how spaced out, in what font, and on what color.


Who is This For?

This is helpful for:

  • Anyone who needs larger text than a website gives them
  • Readers with dyslexia, who often read more with wider spacing
  • People who find black on white harsh or glaring
  • Anyone reading for a long stretch

Open Text Preferences

Open Immersive Reader first. You can start it from the floating toolbar, from the Helperbird menu, or from the Tools menu in the PDF Reader.

Once it is open, the three buttons in the top-right corner hold every setting.

Click AA.

Text Size

Drag the slider. The text resizes as you drag, so you can stop when it feels right rather than guessing at a number.

Go larger than you think you need. Immersive Reader reflows the text to fit, so nothing is cut off, and larger text is one of the cheapest ways to read for longer without tiring.


Increase Spacing

This widens the gaps between letters, words and lines together.

It is worth turning on even if the text looks fine to you. Crowded letters are a common reason words seem to swim or swap places, and spacing them out is often more effective than making them bigger.


Font

Three choices: Calibri, Sitka and Comic Sans.

Comic Sans is there for a reason, whatever its reputation. Its letters are less symmetrical than most, so b, d, p and q are harder to confuse, which some readers with dyslexia find genuinely easier.

If none of the three suits you, Helperbird has a much wider set of fonts for ordinary web pages.


Themes

The color swatches change the page and text color together. More colors opens the full set.

A cream or soft color instead of white reduces glare, which helps if you get visual stress or find white pages uncomfortable. Black is there for reading in the dark.


Show Source Formatting

On by default. It keeps the bold, italics and headings from the original page.

Turn it off if you want every word to look identical, which some readers find calmer.

Next: Grammar Options and Reading Preferences.

Huge fan of the zoom feature. It trumps the native zoom in your browser since the zoom level you set actually stays with you no matter what page you go to, which is very helpful and meshes well with the other features the app offers.
