Anthropometric Walkway Width Two-Person Passing Checker

Two actual occupied body widths plus shared passing gap and two wall gaps, unlike single-person doorway or egress standard. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.

Description

Two people passing need space for both body widths and chosen clearances.

Two people passing need space for both body widths and chosen clearances.^[1]

A computed width reserve describes those dimensions and does not establish a building-code minimum. Use this tool to calculate anthropometric Walkway Width Two-Person Passing Checker from the supplied measurements and assumptions.

When to use Anthropometric Walkway Width Two-Person Passing Checker

Use this tool to calculate anthropometric Walkway Width Two-Person Passing Checker from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.

How to use Anthropometric Walkway Width Two-Person Passing Checker and understand its results

Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
Enter firstPersonOccupiedWidthCm, secondPersonOccupiedWidthCm, callerBetweenClearanceCm, callerWallClearanceCm, observedWalkwayWidthCm, using the field meanings and rules below, then run the tool.
Read requiredPassingWidthCm, signedPassingReserveCm. Interpret the fields using their units, signs and evidence conventions below.
If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.

Input field	Meaning	Value type	Requirement
firstPersonOccupiedWidthCm	First person occupied width cm	number	Required
secondPersonOccupiedWidthCm	Second person occupied width cm	number	Required
callerBetweenClearanceCm	Caller between clearance cm	number	Required
callerWallClearanceCm	Caller wall clearance cm	number	Required
observedWalkwayWidthCm	Observed walkway width cm	number	Required

Enter positive widths for both people and the walkway, with nonnegative between-person and wall clearances in the same length unit. Required width adds both body widths, one between-person clearance and two wall clearances. Return required width and signed available-minus-required reserve, without a pass boolean or installed minimum.

required=width1+width2+betweenClearance+2×wallClearance; reserve=walkway−required

Use the exact units, boundary rules, ordering and missing-evidence conventions above.

Output field	Meaning	Value type
requiredPassingWidthCm	Required Passing Width Cm; follow the units, sign, ordering and evidence convention stated above	number
signedPassingReserveCm	Signed Passing Reserve Cm; follow the units, sign, ordering and evidence convention stated above	number

Limitations and assumptions

A computed width reserve describes those dimensions and does not establish a building-code minimum. Interpretation depends on the units, sampling scope and exact model described above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.

Alternative or Complementary methods

Use Anthropometric Shoulder Breadth Doorway Clearance Checker for this related task: Shoulder breadth and wall clearance jointly determine a geometric passage allowance.

Use Anthropometric Shelf Spacing Vertical Storage Planner when its separate inputs and assumptions fit the question: Shelf spacing must accommodate object height and chosen handling clearance.
