Reconcile two completed, de-identified arm-span and stature records with explicit protocols, units, quality-control context and an independent same-record difference.
Choose your path
Reconcile two de-identified completed arm-span and stature records with explicit definitions, units, replicate/precision context and an independent same-record signed difference without ranking people or making tactical, scouting, selection, performance, development or health claims.
Reproduce one completed two-row anthropometry comparison without losing protocol, replicate or source-unit context.
Preserve the arm-span and stature definitions, measurement/QC notes, both de-identified source rows and one independent signed subtraction.
Receives exact cm/in arithmetic and a same-record reconciliation while collection quality and analysis remain with the study protocol.
Verify two extracted arm-span and stature rows without treating reported precision or a generic reach label as measurement equivalence.
Record the publication/table sources, exact definitions, source units, rounding context and independently prepared A-minus-B result.
Can identify transcription or arithmetic disagreement without a population, performance, traceability or fitness-for-purpose conclusion.
Understand two completed measurement records without receiving tactical, talent-selection, development, medical or sport advice.
Use non-identifying record labels, preserve what is known about protocol and quality control, and compare only the entered signed differences.
Can reproduce the arithmetic while identity, ranking, sport choice, tactics, performance, development, health and safety remain outside the result.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

PhenX defines arm span as the maximum distance between extended middle fingers measured across the back and standing height as vertical head-to-heel stature under its stated posture. Preserve the exact protocol used for each completed record; a generic reach label or self-report is not silently interchangeable.
Comparable record = defined measurand + landmarks/posture + equipment/QC + replicate/precision rule + source value/unitNIST states that one international inch is exactly 25.4 millimetres. Conversion preserves the entered quantity and source unit; it does not add precision, validate positioning or equipment, establish uncertainty or make a measurement traceable or fit for purpose.
Inches × 2.54 = centimetresNegative, zero and positive values show arithmetic direction only. Each record's arm-span-minus-stature value and the A-minus-B stature value are supporting subtractions, not norms, thresholds, advantages or explanations of performance.
A-minus-B arm span = normalized arm span A − normalized arm span B; reconciliation = computed difference − independent differenceUpdated: August 2026
A coordinator compares one completed 74-inch arm-span row with one 180-centimetre row, preserving the protocol and replicate/precision notes. The worksheet identifies any arithmetic mismatch without validating collection quality or interpreting the people measured.
A reviewer records the publication table, arm-span and stature definitions, source units and rounding context for two de-identified rows. The result checks subtraction against an independent worksheet while population inference stays outside this tool.
An adult copies two historical measurement records without names, documents that posture and calibration were not independently verified, and reviews the arithmetic only. The result gives no tactical, scouting, selection, development, health or performance advice.
Arm span, standing height and sport-database reach labels can use different definitions, landmarks, postures, equipment and precision. This worksheet preserves the source records and compares only exact unit conversions and signed differences. It does not validate a measurement or traceability claim, rank people, estimate striking or kicking range, recommend tactics, scout talent, select a sport or role, predict performance, interpret development or health, or replace a responsible measurement protocol or qualified review.
