Cumulative Reach Distance

Strain Risk Score
78/100
Risk Level
High
Reach strain appears high. Redesign workstation layout and increase recovery intervals.
Planning aid only. Confirm final risk with on-site ergonomic review and worker feedback.
We can build and embed a custom version of Repetitive Reach Distance Strain Calculator for your brand and workflow.
Calculates how much total reaching distance is accumulated during the task window.
Captures how often reaches occur per minute and how that frequency impacts fatigue risk.
Applies load-level multipliers to represent additional strain from heavier handling.
A 42 cm reach repeated 14 times per minute over 3 hours often indicates moderate-to-high shoulder-arm strain pressure depending on load.

The model estimates repetitive reach burden by combining distance, repetition rate, duration, and load, then maps the result to practical ergonomic risk bands.
Inputs: Reach distance + reaches/min + task duration + load levelOutput: Cumulative reach (m) + risk score + risk band + recommendationUse Case: Workstation redesign and repetitive-task risk screeningPair this tool with posture, armrest, and RSI calculators for broader repetitive-work risk management.
Explore Accessibility & Ergonomics CalculatorsResult: Moderate-to-high repetitive reach pressure often indicates a need for closer item staging and rotation scheduling.
Final intervention should be validated with observed task flow and worker feedback.
