Make it bigger in your Personal settings, under How it looks → Text size. It's set on each device, so you can have big writing on your tablet and normal on your laptop. For example, Grandad can turn it right up on the tablet he uses in his armchair. Your browser's own zoom works too.
Where to find it
Press your name in "Signed in as" (top row) → your card opens → Personal settings on the card's button row
On a phone: if the card's buttons are tucked away, press ☰ Menu first.
