Being and OG I have trouble reading the small font in the posts on my Kindle. How do I adjust the font size? Thank you

lots of us here are old, and a few are very old.
I assume font size might mean print size, but ive no clue what a kindle is.
I can place my thumbs on my screen and by moving them apart increase the print size, or reduce it by doing the opposite.
And no doubt some are telling me what else i can do with my thumbs. lol

Can't help you with the Kindle, but on a PC with a mouse you can hold down the CTRL key while rolling the center mouse wheel forward to increase the size of the page in any browser. Doing the same but rolling the mouse wheel rearward will decrease the size of everything in kind.
