Wheelchair Reach Display Height Compliance Checker
Actual vertical-height window screen under independently applicable policy. Lateral reach, obstructions, floor space, users and local accessibility law remain external; not wheelchair accessibility/compliance certification.
Description
Wheelchair reach depends on the applicable access standard and the actual approach geometry.
Wheelchair reach depends on the applicable access standard and the actual approach geometry.1
A vertical height comparison alone does not establish accessible use.
When to use Wheelchair Reach Display Height Compliance Checker
Use this tool to calculate or review the supplied observations under the stated rules. Establish the object or visitor scope, measurement units and independently applicable conservation, engineering, access or editorial reference.
How to use Wheelchair Reach Display Height Compliance Checker and understand its results
- Establish the object or visitor scope, measurement units and independently applicable conservation, engineering, access or editorial reference.
- Enter observedDisplayControlHeightMm, callerApplicableMinimumReachMm, callerApplicableMaximumReachMm, using the field meanings and rules below, then run the tool.
- Read result.withinCallerVerticalReachWindow. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedDisplayControlHeightMm | Observed display control height mm | number | Required |
| callerApplicableMinimumReachMm | Caller applicable minimum reach mm | number | Required |
| callerApplicableMaximumReachMm | Caller applicable maximum reach mm | number | Required |
Require nonnegative measured control height and minimum reach height in millimeters. Maximum must be no smaller than minimum. Return true for inclusive minimum≤height≤maximum. No approach geometry or access standard is inferred.
withinVerticalReach=(minimumMm≤heightMm≤maximumMm) Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.withinCallerVerticalReachWindow | Within Caller Vertical Reach Window | boolean |
{
"input": {
"observedDisplayControlHeightMm": 1000,
"callerApplicableMinimumReachMm": 400,
"callerApplicableMaximumReachMm": 1200
},
"output": {
"result": {

}
}
}Limitations and assumptions
Object condition, observation coverage and applicable references determine applicability. A supplied comparison or record does not certify conservation treatment, engineering, access compliance or insurance eligibility.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
