Custom Typeface for Masimo Medical Devices

One custom typeface embedded across 14 Masimo B2B and B2C products

In spring 2022, Masimo engaged Fontfabric to design a bespoke UI/UX typeface—Masi Sans Pro—for patient monitors, wearables, handhelds, and companion apps. The brief required a device-ready system covering Extended Latin, Cyrillic, Greek, and Arabic (including Farsi) with a weight range from Light to Black, plus italics for applicable scripts, while maintaining continuity with existing UI functional cues. Exclusive ownership replaced ongoing third-party licensing and simplified enterprise deployment. The project completed in 90 business days.

Insights

Tabular figures were set as the default to stabilise vital-sign columns and alarm readouts on small displays.
Two design directions—'The Accurate' (open terminals, sharpened details) and 'The Reliable' (humanist grotesque)—were explored; Masimo selected The Accurate for clinical fit.
Arabic and Farsi received native script engineering with screen-first stroke modulation; italics were explicitly excluded for Arabic.
CJK coverage was deferred to a future phase; Noto was recommended as an interim pairing to maintain multilingual UI consistency within schedule and budget.
