What this is
What is an anthropometric fit check?
What is an anthropometric fit check?
A measured or data-based test of whether a workstation's critical dimensions, working height, reach, seat height, knee clearance, grip span, aisle width, accommodate the range of body sizes in the population using it, rather than only an average figure.
Who should carry out a fit check?
Ergonomics, drawing on data about the actual workforce rather than a generic table alone. Where the site's population differs in age, sex or ethnic mix from a table's reference population, the table is a starting point, not a substitute for measurement.
How is a fit check different from a workstation design review?
The design review is the general pass over a proposed workstation: dimensions, materials flow, hygiene, whether the concept is sound. The fit check is the specific, quantified test the design review calls for, dimension by dimension.
Scope
When is an anthropometric fit check required?
This check is the quantified, population-level test behind a design decision. It is misused either as a stand-in for the design review that should have happened first, or as a check of one individual's setup rather than the range a workstation needs to serve.
Use this template when
- A workstation design review has called for a quantified population fit test
- A workstation has been modified, in dimension, layout or equipment, and needs re-testing
- The workforce using a workstation has changed, in stature range, sex mix or task assignment
- Compensating behaviour has been observed or reported: standing on something, stretching, or an inability to perform the task
- A linked record needs this one to exist: links job, asset
Do not use it for
- Workstation Design Review, the general design-stage review this check supports, not a substitute for it
- Tool and Equipment Ergonomic Review, which covers hand tools rather than a fixed workstation's dimensions
- Manual Handling Assessment, needed once a task's loads and frequencies are defined, separately from whether the station fits
- Office Workstation Self Assessment or Display Screen Assessment, individual self-reported checks, not a population-level test
- Recording the resulting equipment change itself, which belongs in a work order or the asset record
Compliance mapping
Which ISO 7250 requirements does this satisfy?
ISO 7250 standardises how body dimensions are defined and measured; ISO 6385 sets the design principle the data is applied against.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 7250-1 | Body dimensions defined against a consistent set of landmarks, so measured or published data can be applied without ambiguity | Workforce measured |
| ISO 7250-1 | Population sampled across the expected user range, including both sexes, rather than a single reference individual | Workforce measured |
| ISO 6385:2016 cl.6 | Design accommodates the 5th to 95th percentile for each critical dimension, with the range required stated | Dimensions checked |
| ISO 6385:2016 cl.6 | Adjustment provided where a single fixed dimension cannot accommodate the required range | Dimensions checked |
| CSA Z412 | Workstation dimensions checked in practice, against reach, grip and clearance, not only against a drawing | Practical checks |
| ISO 6385:2016 cl.6 | Compensating behaviour during use, reaching, stooping, standing on an object, treated as evidence the fit failed, not a workaround | Practical checks |
| ISO 6385:2016 cl.4 | Result recorded with percentage of workforce accommodated, any excluded population, and remaining action identified and owned | Outcome |
What it does not cover
- Workstation Design Review, the general design-stage decision this check exists to support with quantified population data.
- Tool and Equipment Ergonomic Review, which assesses hand tools for grip, weight, vibration and trigger force.
- Manual Handling Assessment, needed once the task's loads, distances and frequencies are defined.
- Office Workstation Self Assessment or Display Screen Assessment, individual self-reported checks, not a population-level test.
- The equipment change or work order itself, which follows a failed fit but is recorded in the asset or change record.
Global
Anthropometric Fit Check requirements by country
No jurisdiction names anthropometric fit checks directly. The duty arrives through work equipment suitability requirements and, where a design excludes workers by size, duties to make reasonable adjustment.
OSH Act General Duty Clause; Americans with Disabilities Act reasonable accommodation
No standard requires anthropometric testing. A workstation excluding workers by stature or reach can raise an accommodation question once identified.
The check reduces both exposures before either becomes a live case.
Provision and Use of Work Equipment Regulations 1998; Equality Act 2010, reasonable adjustment
Work equipment must suit the person using it. A fixed design excluding a protected group disproportionately can trigger a reasonable adjustment duty once known.
Recording percent accommodated and workers excluded turns an informal complaint into a documented, actionable finding.
ISO 7250-1, ISO 6385:2016, CSA Z412
ISO 7250 standardises measurement of body dimensions; ISO 6385 sets the design principle those dimensions are checked against.
Where a customer references ISO 6385, this check is evidence the design was tested against real population data, not assumed.
How to complete it
How to complete an anthropometric fit check, step by step
The template prompts for a percentage and a pass or fail. What determines whether it tested anything real is the population behind that number.
Published tables are a reasonable start, but a workforce differing in age, sex mix or ethnic background from the reference population will not match it. Note how far the site's workforce is likely to diverge, and measure directly where it matters.
5th and 95th Percentile Accommodated are recorded as two separate answers for a reason: a station fitting the middle of the range comfortably can still fail at either end, and it is the end that gets excluded, not the middle.
Standing on a pallet, stretching to reach a control, or bringing a box to stand on are not evidence workers adapted successfully. They are the visible sign the design did not fit the person, and the field exists to capture that rather than let it pass as normal practice.
A check finding a workstation excludes part of the workforce is only useful if that finding reaches the design review it came from and the asset record it belongs to, so the next modification does not repeat the exclusion.
What auditors find
Most common anthropometric fit check findings
The check itself is usually completed against a real workstation. The findings concern data that does not match the workforce, and outcomes that do not match the data above them.
| Finding | Clause | What fixes it |
|---|---|---|
| Data Source recorded as a published table with no note on how the site workforce compares to the reference population. | ISO 7250-1 | Record the site's own stature range and sex mix, and flag where it diverges from the table used. |
| 5th or 95th Percentile Accommodated recorded as no, but Fit Acceptable recorded as yes overall. | ISO 6385:2016 cl.6 | An excluded percentile is a failed fit for that dimension; do not let an overall pass absorb a specific exclusion. |
| Workers Excluded By This Dimension recorded as greater than zero with no action raised. | ISO 6385:2016 cl.4 | Raise an action against every dimension that excludes workers, even where the overall percentage looks acceptable. |
| Compensating Behaviour Observed populated with an example, but Fit Acceptable still recorded as yes. | ISO 6385:2016 cl.6 | Score compensating behaviour as evidence against fit; the field exists to catch this contradiction. |
| Both Sexes Represented recorded as no, on a workforce that includes both. | ISO 7250-1 | Re-sample or re-source data to represent the actual population before treating the percentile figures as reliable. |
| Platforms Safe And Stable recorded as improvised, with no CAPA raised. | CSA Z412 | An improvised platform is a fit failure with an added fall risk; raise a CAPA rather than leaving it in place. |
Case in point
Case in point: the check that measured the table, not the workforce
A new inspection bench was fit-checked using a published table sourced by the equipment vendor. The check recorded height, reach and knee clearance against the table's percentile figures, marked 5th and 95th percentile accommodated as yes, and closed with Fit Acceptable as yes and 92 percent accommodated. Data Source was published statistics; Both Sexes Represented and the site's own stature range were left blank.
Within weeks, two of the site's shorter workers were seen standing on an upturned crate to reach the inspection point, exactly what Compensating Behaviour Observed exists to catch. The workforce at the bench was drawn from a population shorter, on average, than the table's reference population, and the 92 percent figure described the table's population, not the one standing at the bench.

From a document you fill in to a programme that runs itself
The check itself is a snapshot. What slips is whether its data source matches the real workforce and whether an excluded population reaches an action.
Holds the fit check library against the workstation and job registers, flags a check built on a published table with no site data, and routes the result back to the design it tested.
Connects the fit check to the workstation's asset record, so a later modification raises the re-check this template expects rather than relying on memory.
Watches for a finding that recommends adjustability or excludes part of the workforce, and keeps the resulting change moving through management of change rather than stalling as a note here.
Coordinates ergonomics and engineering on an open fit check, rolls exclusions and pending actions into one view, and holds every write for approval before it touches a record.
This template lives in KnowErgo — ergonomics. Task assessment, video posture analysis, rotation and workstation redesign.

Anthropometric Fit Check definitions and key terms
- Percentile range (5th to 95th)
- The span of body dimensions covering nearly the whole relevant population; the standard target for accommodation in workstation design.
- Anthropometric data source
- Where the body dimension figures come from: published statistics, a trade association, direct measurement, or a consultant, each with different reliability for a given site.
- Compensating behaviour
- An observed workaround, standing on an object, stretching, or stooping, indicating a workstation does not fit the person using it; a failure sign, not adaptation.
- Adjustability
- A design feature letting a single dimension, most often height, change to suit different users, used where no fixed dimension covers the required range.
- Landmark measurement
- The consistent anatomical reference points ISO 7250 defines so a body dimension means the same thing wherever and by whomever it is measured.
FAQ
Frequently asked questions about anthropometric fit check
What is an anthropometric fit check?+
A test of whether a workstation's critical dimensions accommodate the range of body sizes in the workforce using it, recorded dimension by dimension with a percentile figure, not a single pass or fail judgement.
Why check the 5th and 95th percentile separately?+
Because a workstation can fit the middle of the range comfortably while still excluding people at either end, and it is the shortest and tallest workers who get excluded when only an average is checked.
Is a published anthropometric table good enough?+
As a starting point, yes. As a substitute for knowing the site's own workforce, no. A table built from a different reference population, in age, sex mix or ethnic background, will not match a workforce that differs from it.
What does compensating behaviour mean, and why does it matter?+
A worker has found a workaround, standing on something, stretching, or stooping, because the workstation does not fit them. It is direct evidence of a failed fit, and treating it as normal practice is the most common way a check misses the problem it exists to catch.
How does this check relate to the workstation design review?+
The design review is the general pass over a proposed workstation; this check is the quantified population test the review calls for, and the two records link through the check ID.
When should a fit check be repeated?+
At design stage, and again after any modification, because a change in dimension, layout or equipment can reintroduce a fit problem the original design had solved.
