How Do Historians Know How Tall Historical Figures Were?

Historians establish height by asking what survives: a recorded measurement, a person’s own description, identified skeletal remains, fitted objects, or only an impression in a written account. Those sources do not offer the same level of precision. Some historical figures have well-supported approximate heights; others have no defensible numerical answer.

The first step is not converting a number into centimetres. It is finding out where the number came from. A result repeated on many websites may still rest on one ambiguous sentence—or on no identifiable evidence at all.

1. Written measurements and self-descriptions

A documented measurement can be useful if its context is known. Ask who recorded it, when, in which units, and under what conditions. Was the subject an adult? Were shoes included? Is the record contemporary, or does a later writer attribute it to someone else?

Self-description is valuable but remains a report. Lincoln’s description of himself as nearly 6 feet 4 inches provides a different kind of evidence from a modern clinical measurement. The Library of Congress preserves the 1859 material sent to Jesse W. Fell.

2. Estimates from skeletal remains

Researchers can reconstruct stature from skeletal elements or estimate it through the relationship between long-bone lengths and living height. The femur and tibia are useful because they contribute substantially to the body’s vertical dimensions.

These are estimates, not magic conversions. Equations depend on reference data; proportions vary; incomplete or damaged remains create further uncertainty. Scientific guidance on stature estimation explains why appropriate methods and limitations must be reported.

A further question comes before the calculation: whose bones are they? A technically sound estimate from an unidentified skeleton cannot establish the height of a named ruler. Richard III’s identification required several kinds of evidence, as the Leicester project overview explains.

3. Armour, clothes, and other fitted objects

An object made for a known wearer can constrain our understanding of their build. It still has to be dated, identified, and interpreted. Clothing can change shape; armour may include allowances for layers and movement or be altered after manufacture.

Henry VIII’s surviving armour offers a useful case. The Royal Armouries’ account of his foot-combat suit shows why the object’s intended use matters. A fitted suit is stronger evidence than a flattering full-length portrait, but its external height is not automatically the wearer’s height.

4. Descriptions such as “tall” or “short”

A description can establish how someone was perceived without supplying a number. Tall compared with whom: an opponent, a courtier, a local population, or the author’s expectations? A writer might also use physical description to reinforce a character portrait.

For example, Caesar’s height should not acquire an exact centimetre figure merely because an ancient author calls him tall. An adjective is not an unstated measurement waiting to be recovered.

5. Old units and misleading decimal places

The word “foot” does not always identify the same unit. The note to Suetonius’s account of Augustus explicitly distinguishes Roman from English measure.

Correct conversion is necessary, but not sufficient. Reporting an uncertain height as 169.873 centimetres makes the arithmetic look more trustworthy than the source. Preserve the source’s uncertainty with words such as approximately, reported, or estimated.

6. Comparing people with population averages

A cemetery sample is not a census of an entire civilization. Region, period, age, sex, preservation, and estimation method affect comparisons. Research on sample size and representational bias illustrates why those choices matter.

Our guide to Ancient Roman height addresses this population question. It should not be used to manufacture an individual ruler’s stature from an average.

A quick checklist before accepting a height claim

• Can the number be traced to a named source?
• Is it a measurement, an estimate, or a description?
• Are the units and comparison group appropriate?
• Has the identification of any remains or fitted object been established?
• Does the reported precision match the evidence?

Sometimes the correct answer is that we do not know. That is a historical conclusion, not a gap that a confident-looking height chart can fill.
