Absolute height and the proportions within a letter are separate observations.
Handwriting and graphology
Measuring millimetres requires a known scale. Within one image, it may still be possible to compare the height of the letter body with an extension or with letter width.
Two signatures fill equal boxes on screen, but one was automatically enlarged. Compare their internal proportions and state whether the original dimensions are known.
Graphology associates handwriting with personality. Each proposed link needs an independent test of its predictive value.
Handwriting and graphologyA person may form one letter several ways even within one sentence. Comparison needs a range of examples rather than the nearest match.
Handwriting and graphologyExaminers consider how a stroke travels, breaks and changes along its path. With a photograph the first question is which details the image actually retains.
