US Secretary of State Marco Rubio has ordered diplomats to start using the Times New Roman font again, reversing a change made under the previous administration.

Rubio's predecessor, Antony Blinken, made the switch to Calibri in 2023, saying it was more accessible for people with visual disabilities - a change Rubio labelled 'wasteful'.

Monolith typeface designer Alistair McCready says Calibri's more suited to readers by design, but it depends on the individual. 

"There's all sorts of things that go into reading, not just the way you see or how clearly you can see - it's how you interpret letters and shapes."
