As part of the formulation of a biological profile, the estimation of stature is an important element that
provides useful data towards narrowing the pool of potentially matching identities. Recent literature has
demonstrated that anthropometry of the hand has considerable promise for the accurate estimation of
stature; although the technique has only been tested in a relatively limited range of populations. The aim
of the present study, therefore, is to assess the reliability and accuracy of using anthropometric hand
measurements for the estimation of stature in a contemporary Western Australian population; we also
evaluate whether stature can be accurately estimated from the measurement of handprints.
The study sample comprises 91 male and 110 female adult individuals. Following the measurement of
stature, seven measurements are taken on each hand and its corresponding print. To establish the
reliability of acquiring these measurements, a precision study was performed prior to primary data
collection. Measurements data are analysed using basic univariate statistics and simple and multiple
regression analyses. Our results show that the degree of measurement error and reliability are well
within accepted standards. Stature prediction accuracy using hand and handprint measurements ranges
from �4.74 to 6.53 cm, which is comparable to established skeletal standards for the hand. This study
provides new forensic standards for the estimation of stature in a Western Australian population and also
demonstrates that the measurement and analysis of handprints affords a novel source of profiling data that is
statistically quantified.

1. Introduction
The modern role of a forensic anthropologist has evolved toinclude not only the study of skeletal remains, but in an era ofglobal migration (both legal and illegal), and incidences ofincreased terrorism, crime and natural disasters involving massfatalities, the analysis of living individuals and/or body parts ofdecedents is frequently required. The minimum expertiserequirement of a practicing forensic anthropologist mustinclude the ability to formulate a biological profile (osteobio-graphy – sex, age, ethnicity and stature). A biological profile,alongside other skeletal markers (e.g. ante-mortem pathology)can provide useful information towards establishing theidentity of unknown skeletal remains; for investigating authori-ties, this profile effectively narrows down the pool of potentialmatching (tentative) identities – positive identification canthen be established using traditional markers (e.g. DNA ordental) [1].

It is generally accepted that the most accurate biological profileis formulated using contemporary population specific standards.This issue has been considered many times in the literature andbasically relates to population specific variability in the relativeexpression of morphological characteristics used to estimate, forexample, sex, age and stature (e.g. [2–4]). Populational variabilityis also not ‘temporally static’, thus contemporary standards,devised on modern representative samples, are required. Seculartrends in stature are an example of the importance of contempo-rary forensic standards. For example, under conditions of adequateaccess to nutrition and health services, children and adults mayattain a larger stature compared to individuals from the samepopulation from several generations earlier; this is known as apositive secular trend. Conversely, the opposite effect (negativesecular trend) has also been demonstrated to occur underconditions of poor nutrition and health [5].
In instances where a forensic investigator is presented withcommingled, dismembered and/or incomplete remains, statureestimation standards requiring a complete skeleton (anatomicalmethod – e.g. [6–8]) or complete long bones (mathematicalmethod – e.g. [9,10]) may not be applicable. In such circumstancesstandards devised from different parts of the skeleton or body

limbs may provide a practical alternative. There are numerouspublications describing anthropometric approaches to estimatingstature from different body parts. The feet (and to a lesser degreefootprints) have been shown to be a relatively accurate biologicalcharacteristic from which stature can be estimated (e.g. [11–13]).Other studies have considered the relationship between statureand head dimensions in living individuals (e.g. [14–16]) andprovided standards for their respective populations. It is importantthat the forensic investigator select the most appropriatemethod(s) and any further related studies are solidly based on ameaningful biological, and not just statistical, relationshipbetween body parts and living stature (see [17]).
Previous research in various populations has demonstrated thatstature can be accurately estimated from hand dimensions: e.g.North Indian, SEE �3.16–5.60 cm [18]; South Indian, SEE �3.65–5.73 cm [19]; Turkish, SEE �3.91–4.59 cm [20]; Egyptian, SEE �5 cm[21], SEE �4.22–5.48 cm [22]; Mauritanian, SEE �4.16–4.96 cm [23].Most recently, Ahemad and Purkait [24] demonstrated that staturecan also be accurately estimated from hand impressions in an Indianpopulation; SEE �4.64–5.50 cm. The studies outlined above demon-strate the forensic utility of anthropometric measurements of thehand and handprints for estimating stature and, importantly, with anaccuracy closely approaching that of established long bone standards(e.g. [9]). Clearly there is an abundance of research on populationsprimarily from India and the Middle East. It would be useful, however,to assess whether this method of stature estimation has forensicpotential in other populations.
There are currently no population specific standards forestimating stature in a Western Australian population. To thatend, the purpose of the present study is to assess the reliability andaccuracy of using anthropometric hand measurements for theestimation of stature in that population. These standards wouldafford a means of estimating stature in forensic investigationsinvolving disarticulated and/or incomplete fleshed humanremains. We also examine if stature can be accurately estimatedfrom the measurement of handprints; as prints are commonlyfound at crime scenes, such standards may prove useful in criminalprofiling.
2. Materials and methods
2.1. Materials
This study examines measurements taken from 201 adult subjects (91 male; 110
female) currently residing in Western Australia. Subjects were given an information
sheet and were required to sign a consent form before participating in the study.
Each subject was required to fill in a questionnaire containing basic demographic
(e.g. sex; age; ethnicity) and general (e.g. handedness) questions. The mean age of
the male individuals is 38.2 years (range 19–68) and for the females it is 36.5 years
(range 18–63). The study sample comprises individuals of various ethnic
backgrounds (primarily Caucasian) but overall it is representative of a ‘typical’
Western Australian population (see [25] for specific frequency statistics). Only
individuals without any medical history of hand, foot and backbone problems were
recruited for the study. Ethical approval to undertake this research was approved by
the Human Research Ethics Committee of the University of Western Australia (RA/
4/1/2382).
2.2. Methods
2.2.1. Handprint acquisition
A flatbed scanner (CanoScan LiDE 100) was used to acquire images (400 dpi) of
the hands, which were then converted to handprints. The cover of the scanner was
removed and modified to incorporate a mounting box, photographic scale and
polystyrene plate on the plenum; this allowed subjects to place their hand in a
standardised position and provided a uniform scanning background that is devoid
of ambient light and has a reference scale. To obtain the most accurate
approximation of a handprint the scanned images are edited using the Photoshop1
software package (SC3 edition); this involves image conversion to grey-scale and
adjustments to brightness and contrast. The resultant images are then printed at
1:1 and measured (see below) using a 150 mm digital sliding caliper (Mitutoyo 700-
128 – stated accuracy �0.1 mm); a measuring tape (Paleo-Tech Concepts, Inc.) was
used for any measurements beyond the maximum size limit of the digital caliper.
2.2.2. Measurements
Stature (living height) is measured using a stadiometer (Seca 204); each subject
was asked to stand bare-footed on the flat platform, with heels placed together and
touching the base of the vertical board. The head is positioned in the Frankfort
Horizontal (FH) plane against the vertical board; the subject was then requested to
maintain an erect position with their back in contact with the vertical board and arms
placed on the side of the thigh. The horizontal sliding bar is then positioned on the
contact point of the vertex of the head and stature is recorded in centimeters [26].
Seven anthropometric measurements were taken on each individual hand and
corresponding handprint using a digital caliper and (where required) tape (see
above); measurements are defined in Table 1 and illustrated in Figs. 1 and 2. The
definition of the handprint measurements are the same as those provided for the
anthropometric measurement of the hand, with the exception of handprint breadth
(HPB) and handprint length (HPL); it is not possible to locate the skin or bone
landmarks required to define those measurements. Therefore, the measurement of
HPB and HPL are defined accordingly in Table 1.
2.2.3. Statistical analyses
A precision study was performed prior to primary data collection. Stature, hands
and handprints of the same four subjects were measured on four different
evaluation days, with a minimum of 24-h between re-measurement. Intra-observer
error was determined to be within accepted standards for all measurements
(R > 0.9; rTEM < 5%) [27].
Following the calculation of normal descriptive statistics, bilateral asymmetry in
the measurement data was evaluated using a paired samples t-test. The accuracy of
stature estimation using hand and handprint measurements was then assessed
using sex-specific simple linear regression analyses; measured stature is regressed
onto the individual measurements from both the left and right hand. Accuracy is
quantified using standard errors of the estimate (the standard deviation of the
residuals). A series of stepwise regression analyses were also performed to assess
whether multiple measurements improve prediction accuracy. Statistical analyses
were performed using the SPSS 19.0 software program.
3. Results
3.1. Descriptive statistics and bilateral asymmetry
The mean male (n = 91) measured stature was 178.5 cm (SD7.05; range 162.4–200.5) and for females it was 163.7 cm (SD 7.14;range 149.4–191.3). The mean, standard deviation and correlationto stature for each of the seven hand and handprint measurements(left and right for both sexes) are shown in Table 2. Overall it isreadily apparent that there appears to be very little bilateral

variation in the hand and handprint dimensions. The t-testsrevealed that only the measurement of hand breadth wassignificantly different between the left and right sides (male:t = 4.496, P < 0.05; female t = 8.077, P < 0.05); the difference,however, was very small (male: 0.06 cm; female 0.09 cm) with theright side larger in both instances (Table 2). Handprint breadth wasalso bilaterally significantly different in females (t = 5.403;P < 0.05). All of the measurements are significantly correlated tostature (P < 0.01). It is evident that for the hand measurements, thevariable most strongly correlated to stature is hand length – thesame relationship was expressed for the left and right hand in each[(Fig._2)TD$FIG]

3.3. Multiple regression
To assess if stature prediction accuracy is improved by utilisingmultiple variables, a series of sex-specific bilateral multipleregression equations were formulated; these are presentedseparately for hand and handprint measurements in Tables 5and 6 respectively. In the interest of brevity, only the three mostaccurate models are presented for each sub-sample. With regard tothe hand measurements, it is evident that in males the smalleststandard error of the estimate is �4.74 cm and in females it is�5.04 cm (Table 5); for the handprint measurements the smalleststandard error of the estimate for males is�4.74 cm and in females itis�5.39 cm (Table 6). The variables generally weighted most stronglyin the multiple regression models (both hand and handprint) in bothsexes are hand length, palm length and in some instances handbreadth (see Tables 5 and 6).
4. Discussion
Stature estimation is an important part in any forensicinvestigation involving the anthropological profiling of unknownhuman remains. The primary aim of this study was to assess thereliability and accuracy of using hand and handprint measure-ments to estimate stature in a Western Australian population.With regard to establishing the reliability of acquiring stature andhand and handprint measurements, we have demonstrated thatthe degree of measurement error and reliability are well withinacceptable standards (R > 0.9; rTEM < 5%) [28–30]. The statisticalquantification of error and uncertainty in the forensic sciences isvital; this applies to not only the degree of error associated withforensic standards (see below), but also the accuracy and precisionof the raw data (measurements) from which they are formulated;the latter is often neglected in forensic anthropological research ofthis nature.
In evaluating bilateral asymmetry in hand and handprintmeasurements, hand breadth was the only variable that wassignificantly different; the relationship was apparent in both malesand females. Where significant bilateral differences have beendescribed, it is generally for the measurement of hand breadth (e.g.[18,24]); other published studies found only minor (non-signifi-cant) bilateral variation (e.g. [19,21,23,31]) which accords with theremainder of the data obtained from the Western Australianpopulation. Hand and handprint length was found to have thestrongest correlation to stature; the former is again a relationshippreviously described in related literature (e.g. [18,19,22,24]).
In assessing the accuracy of our simple linear regressionmodels, the standard error of the estimate (SEE) was lowest usingthe measurement of hand length (SEE �4.74–5.17 cm). Expectedly,other research has demonstrated that this is the most accuratemeasurement for estimating stature, albeit their regression modelshave a higher stated accuracy: e.g. Sanli et al. [20] (�3.50–4.59 cm);Rastogi et al. [19] (�3.65–5.04 cm); Krishan and Sharma [18] (�3.78–5.22 cm); Agnihotri et al. [23] (�4.23–4.96 cm); Habib and Kamal [22](�4.54–5.48 cm). This improved accuracy may possibly be attributedto the lack of diversity in their sample populations, specifically interms of genetic variability. The most accurate handprint regressionmodel was, as expected, handprint length (SEE �5.46 cm); theaccuracy is slightly lower compared to taking a direct physicalmeasurement of the hand (SEE �4.74 cm). Ahemad and Purkait [24]similarly demonstrated that handprint length had the lowest SEE(�4.64 cm) of all their hand impression regression models.
With regard to our multiple regression models for handmeasurements, we demonstrated an equivalent degree of predic-tion accuracy (�4.74 cm) compared to the simple linear models (seeTables 5 and 6). A selection of the aforementioned studies, however,demonstrated increases in prediction accuracy when using multiple

variables (e.g. [18,21,22]). Rastogi et al. suggest that when predictingstature ‘‘. . .multiple regression equations give more accurate results’’[19: p. 188] but the statement was supported using correlationcoefficients; their data actually indicates that their simple linearmodels are slightly more accurate (smallest SEE for a single variable:�3.65 cm; for multiple variables: �3.67 cm – see Tables 6 and 7 inRastogi et al. [19]). It is apparent that in the present study, multipleregression equations are only likely to be beneficial in circumstanceswhere the direct linear measurement of hand length is not possible,but other parts of the hand are available in combination (e.g. palmlength, breadth and other finger lengths). In other words, our dataindicates that when the parts of the hand that individually have aweaker correlation to living stature are used in combination,prediction accuracy is increased.
Conversely, the accuracy of the multiple regression modelsusing handprint measurements showed an increase in predictionaccuracy compared to using single variables. The increase inaccuracy was greater in the male sample (6.8 mm) but very minorfor the females (less than 1 mm); the lowest SEE was �4.74 cm and�5.39 cm for males and females respectively (see Tables 4 and 6).Overall, however, it is apparent that the accuracy of the handprintmodels (both single and multiple) is generally lower compared to thedirect measurement of the hand. The measurement and analysis ofhandprints, however, offer a novel source of profiling data that isstatistically quantified. For example, measurements taken from a fullor partial handprint left at a crime scene could be useful towardsoffering an estimated stature of a suspect; this could supplement anyavailable eyewitness information (e.g. ethnicity; sex; age). It is alsoworth considering that eyewitness estimations of a suspect’s heightare very likely to be less accurate compared to the novel handprintstandards outlined in the present study [32,33].
The hand and handprint standards outlined here offer apractical means of estimating stature with an overall accuracycomparable to established skeletal standards for the hand: e.g.[34]: SEE �4.70–8.14 cm; [35]: standard error of the mean, 5.10–5.67 cm. The clear value of anthropometric measurements of thehand for estimating stature has thus been confirmed in a WesternAustralian population. Furthermore, we have also established that themeasurement of handprints afford a practical means of estimatingstature. It is important to note that in the present paper we have notconsidered sexual dimorphism in the data; this is the topic of arecently completed research project [36] and a manuscript ispresently in preparation that highlights the forensic utility of handand handprint data for the estimation of sex.
5. Conclusions
The present study is part of a larger federally funded ongoingresearch project that is developing population specific standardsfor Australia in the form of an interactive Human IdentificationPackage (HIP). In the current study we have outlined a series ofnew forensic standards for the estimation of stature in a WesternAustralian population; standard error rates range between �4.74and 6.53 cm. The accuracy of anthropometric hand measurements forestimating stature is well established in a variety of populations; theuse of handprint data, however, is still relatively novel and theapplicability of that approach for use in other populations and inforensic case-work should be evaluated by the wider anthropologicaland/or forensic community.
