On facebook very small letter i cannot read,i want to back on normal

It's time to get your eye exam. Sounds like your straining your eyes reading small letters.

click on view thirs on right from file at top of you page click zoom and choose what size text you like

You browser interface is reduce in small font/icon.

hold ( Ctrl then + sign ) to zoom and ( Ctrl then - sign ) is the reverse

Please follow the below steps to solve your problem.
1. Firstly remember your ID and password.
While typing your ID see that Caps lock function is not on if you have small letters in your ID as well as password.
2. After typing the correct ID now move to password tab, ensure that Caps lock function is disabled if your password have only small letters.

If still you are having any problem than send me your query, I will surely try my best to solve your problem.

Thank you for using Fixya.

Increase the letter font size using the control panel setting for Appearance and Themes menu option. This is for Windows operating systems.

It all depends on your internet browser, I couldn't find anything to change text on facebook itself.

For firefox at the top of the screen go to view>zoom then click zoom text only, then go view>zoom>zoom in.
There will be a tick beside the zoom text only to let you know this function is on.

For internet explorer, go to view>text size and then decide which size you would like.

For google chrome the only thing I can see is just to zoom the page in, can't immediately see a text specific option.

The site has the default font size.
Just zoom it using : Ctrl + '+'.
Zoom out using : Ctrl + ' - '.

Hi there,
Please check the VIEW (uppermost corner of the Menu bar) then check for ZOOM.

Good luck! Hope this would help. =)

try hitting ctrl-plus.

Set the font number on your favorite text editing program to something legible, for example, in Word, a size from 5 to 10 is normal letter.
If letter stills going little on printer, then take it for repair.
