What is the Font Size Feature?

Helperbird lets you change the size of text on any website. You can make text larger if it is too small to read comfortably, or make it smaller if you prefer more compact text.

The size change applies to all text on the page instantly. You can adjust it using a simple slider to find the perfect size for you.


Who is This For?

This feature is helpful for:

  • People with low vision who need larger text
  • Anyone who finds website text too small to read comfortably
  • People who get eye strain from reading small text
  • Students reading long articles or documents online
  • Anyone who wants more control over how websites look

Step 1: Open Helperbird

Click the Helperbird icon in your browser toolbar. It looks like a small owl and is usually in the top-right corner of your browser.

This will open the Helperbird menu.

The Helperbird popup with Helperbird switched on, showing the quick actions grid and the All Features button


Step 2: Open the All Features Section

Scroll down to the bottom of the Helperbird menu. You will see a section called All Features.

Click the arrow next to All Features to expand it and show all available features.

The All Features list in the Helperbird popup, showing every feature in alphabetical order


Step 3: Find Text Settings

Look through the list of features until you see Text settings.

It has a yellow icon with the letter "T" on it.

The All Features list scrolled to show the Text settings row and its Open button


Step 4: Open Text Settings

Click on Text settings to open it.

A panel will appear with all of the text options in a single list. This is where you will find the font size option.

The Text settings panel open in the Helperbird popup, showing the Font size control


Step 5: Turn on Font Size

In the panel, look for Font size. It has a yellow icon with an "A+" symbol.

Click the toggle switch next to it to turn it on. The toggle will turn blue when it is enabled.

The Font size toggle switched on in the Helperbird popup


Step 6: Adjust the Size

Once Font size is turned on, a slider will appear below the toggle. A bubble above the slider always shows the current size, and there is a minus button on the left and a plus button on the right.

Drag the slider to the right to make text larger, or drag it to the left to make text smaller. You can also click the minus and plus buttons to change the size one step at a time.

The changes will apply to the website immediately, so you can see the effect as you adjust the slider.

Tip: Start with a small adjustment and keep increasing until the text feels comfortable to read. Everyone has different preferences, so take your time to find the size that works best for you.

The Font size slider moved to 106.0

This extension has been an absolute lifesaver. I have that fantastic combo of ADHD and Dyslexia while trying to go through college. I have difficulty keeping letters in order, seeing the gaps between words, and with ADHD on top, I lose focus A LOT. The immersive reader has been my new best friend. It drowns out the rest of the content on the page, changes the font to something I can read, and highlights the word as it reads to me. My eyes are forced to keep going in the right direction. I can slow down and pay attention to what I'm reading. I don't even have to go back and read the same paragraph 5 times to understand it! The screen overlay has been outstanding for eye strain and being able to distinguish between words and spaces. The custom font and spacing for research articles have been an enormous advantage! I can actually read the research papers now and not have this daunting 2 column fine print page to squint over.All around, this has been the best purchase I've ever had. I use this every day, with every assignment. I don't even struggle with story-based questions anymore. The immersive reader helps me read, listen, and understand the question all at once. I am still exploring what I can use this with and how it can make my academic career, and I keep getting impressed with every new way I find to use it. Seriously, try it out. You won't regret it at all. Even if you don't have dyslexia or ADHD, just try it out. You might find that it helps you understand the content you're trying to learn even better!
