NUMBERS IN LARGER FONTS ARE MORE PERSUASIVE

Summary from the TLDR Marketing newsletter

Larger font sizes make numbers in ads seem more convincing and persuasive. In experiments, a lamp's price was judged 9.3% cheaper and a wine bottle 15% cheaper when the price appeared in a larger font. People also perceived product features as higher quality and were more willing to buy, such as being 25.9% more likely to buy a fitness tracker with a prominently sized “60m waterproof” feature. The effect does not hold for premium or well-known brands.
