Designing for San Marino: the facts that matter

Besides English, the most common home language group in San Marino is Chinese, spoken by 43.8% of residents. Customers here move between languages, so clarity beats cleverness. Say on the website which languages your staff speaks; it is one line of text, and it answers a real question.

25.3% of employed San Marino residents work for themselves, against 11.4% in California. For a one-person business, the website is the storefront, the brochure and the business card at once, and many have nothing but a social media page. Put your name and photo on the website: solo businesses sell the person.

When San Marino customers need you: the seasons

San Marino weather, in normals: August highs around 91°F, December lows around 45°F, measured at Pasadena, 2.5 miles away (1991-2020). Rain adds up to about 20 inches a year, falling on about 26 days with a tenth of an inch or more. About 74 days a year hit 90°F or more. Heat shapes the calendar: outdoor work starts early, afternoons belong to indoor activities, and emergency calls spike in the hottest weeks. Give seasonal work its own page, so the right page is there when the weather turns.
