We can build and embed a custom version of Typing Hours RSI Risk Calculator for your brand and workflow.
Answers: RSI risk from 8 hours of typing, how often to break when coding, and effect of posture on keyboard strain.
8 h/day → 44 pts — largest single driver on full-time desks.
Longer gaps between breaks increase score — 50 min → 12 pts penalty.
Fair + moderate default → 12+11=23 pts before hours and breaks.
Default: 8 h typing · breaks every 50 min · fair posture · moderate intensity → 44+12+12+11 = 79/100 · High · break every 25 min.
