Doryphoros (c. 440 BC)
The canon made stone. Built to roughly seven heads, it embodies the lost treatise and set the template for measured Greek figure proportion.

Figure proportions in heads — the 8-head canon
Use the head as a ruler and the whole body falls into place: nipples at two heads, navel at three, the midpoint at the pubic bone (head four), knees near six, feet at eight. The 8-head canon is an idealisation — real people run 7 to 7.5 — and choosing the right canon for the job is half the skill. Here is where every landmark sits, the real lineage from Polykleitos's lost treatise to Loomis, and how to switch canons for realism, heroic, or fashion work.

On a standing figure the ladder reads cleanly: scale the top division to the head and the central line should land on the pubic bone — the true midpoint. Drag the handle to check the legs really fill the lower four heads.
What the overlay shows
The figure-proportion overlay divides the figure's height into equal head-heights — eight in the default canon — and labels the anatomical landmark on each division: head, nipples, navel, pubis, thigh, knee, calf, sole. A dashed centreline runs through the figure, with shoulder-width and hip-width markers at the standard 2-head and 1.5-head spans, so the shoulder width reads at roughly two heads across. You can switch the canon between 7, 7.5, 8, and 9 heads and toggle male or female landmark distribution.
Scale the overlay so the top division matches the head from crown to chin, and the rest of the ladder predicts where every landmark should fall. It is built for upright, roughly frontal figures; reclining and strongly foreshortened poses need manual interpretation, because the apparent head height changes along the body.
The math, briefly
The head is the module. With head height H, the standing figure is built as a stack of equal units:
total height = 8H · midpoint (pubis) = 4H = 0.50 · shoulders ≈ 2H wide
Three facts make the module work in practice:
- The head as unit. Limb lengths appear to change with pose and foreshortening; the head is a consistent yardstick — the head as unit lets you step down the figure with dividers and answer the practical question of how many heads tall a person is.
- The midpoint is the pubis, not the waist. Because the legs are long, halfway between crown and sole lands at the pubic bone. Fixing this single landmark corrects most figures that "feel wrong."
- The canon is a dial, not a law. 7–7.5H reads as real, 8H as idealised, 8.5–9H as heroic or fashion. Same module, different number of units.
The overlay keeps the units equal as you scale. Open it in the live tool and switch canons to match the brief.
History — what is real and what is myth
Verified history (with primary sources)
5th century BC — Polykleitos. The sculptor wrote The Canon, a now-lost treatise on ideal proportion, and embodied it in the Doryphoros. We know it through later writers; Jerome Pollitt's sourcebook gathers the ancient testimony on what the canon actually claimed.1 Lysippos later slimmed the figure toward eight heads, setting the Hellenistic standard.
c. 15 BC — Vitruvius. De Architectura, Book III, transmitted the proportional human to Rome, including the famous circle-and-square passage that Leonardo would later draw.2 Leonardo's Vitruvian Man (c. 1490) is the Renaissance restatement, set in context by Martin Kemp's study of his work.3
19th–20th century — the teaching canon. Academic anatomy texts fixed the working proportions artists still use: Paul Richer's Artistic Anatomy, George Bridgman's constructive approach, and Jenő Barcsay's measured plates.578 Andrew Loomis's Figure Drawing for All It's Worth (1943) popularised the 8-head construction — and the pubis-as-midpoint rule — for illustrators.4
Claims to keep honest
"The body is 8 heads tall." Only in the canon. Measured adults run about 7 to 7.5 heads; the eighth head is an aesthetic choice that reads as graceful and heroic, not an anatomical fact. Robert Beverly Hale's master-drawing analyses are clear that the academies idealised deliberately.6
"There is one correct canon." There are many. Greek, Renaissance, academic, fashion, and comic traditions each fix a different number of heads. The right one depends on the work, not on a universal truth.
"Proportion equals the golden ratio." The φ-everywhere-in-the-body claim is overstated. Some relationships approximate it, but the working canon is built on simple head-height fractions, not on φ — a caution that echoes the wider golden-ratio mythology.
Which canon, for which work
| If you are drawing... | Use this canon | Avoid... | Difficulty |
|---|---|---|---|
| Observational figure study of a real model | 7–7.5 heads — matches measured human proportion | 8+ heads, which will read as subtly elongated | Beginner |
| Classical / atelier figurative painting | 8 heads — the academic idealisation | Realistic 7-head if you want the heroic read | Intermediate |
| Comic, manga, or monumental heroic figures | 8.5–9 heads for scale and presence | 7-head realism, which deflates the heroism | Intermediate |
| Fashion illustration / croquis | 9–10 heads for the elongated runway look | Realistic canons, which look stocky on the page | Advanced |
| Children and adolescents | 4–6.5 heads, scaled to age | Adult canons, which make children read as tiny adults | Advanced |
Famous figures and their canons
Six works, each built to a deliberate head canon — from classical realism to fashion's elongation.
Apoxyomenos (c. 330 BC)
Lysippos's slimmer eight-head figure — smaller head, longer limbs — became the Hellenistic standard and the ancestor of the modern academic canon.
Vitruvian Man (c. 1490)
Leonardo's diagram of Vitruvius: the figure inscribed in both circle and square, navel at the circle's centre, the canon's most famous single image.
David (1504)
An idealised eight-plus-head figure with deliberately enlarged head and hands, calibrated to be read correctly from far below on its intended rooftop perch.
Loomis figure plates (1943)
The eight-head idealised man and woman that taught generations of illustrators — and popularised the pubis-as-midpoint rule the overlay marks.
Fashion croquis (9–10 heads)
The runway figure stretches the legs to nine or ten heads. The exaggeration is the point — it sells the drape and line of the garment over anatomical truth.
Common mistakes
1
Putting the midpoint at the waist
The most common proportion error: assuming the body's halfway point is the navel or waist. It is the pubic bone — the legs are long — and a high midpoint makes the legs read as stunted.
Fix: set the centre division on the pubis first; build the torso above and the legs below from there.
2
Using one canon for every job
Drawing a real model at eight heads, or a hero at seven. The canon should match the intent — realism, idealisation, or fashion — not be a fixed default.
Fix: pick the head count from the brief (7–7.5 real, 8 academic, 8.5–9 heroic/fashion) before you start.
3
Drawing children as small adults
Applying the 7.5–8 head adult canon to a child. Children have proportionally much larger heads — a toddler is about four heads — so adult proportions make them look like miniature grown-ups.
Fix: drop to 4–6.5 heads scaled to age, keeping the head large relative to the body.
4
Trusting the ladder in foreshortening
Applying straight head-height divisions to a reclining or sharply foreshortened pose. The apparent head height changes along a foreshortened body, so the even ladder lies.
Fix: use the canon as a rough check on upright figures; switch to observed measuring and overlapping forms for foreshortened poses.
How different disciplines use it
For figure painters
Block the head-height ladder before committing a single contour. Most life-drawing errors are proportion errors caught late; a quick eight-line check against the model fixes a too-short leg or a sunk pubis in seconds. Atelier training (Florence Academy, Watts) still teaches the canon as the scaffolding underneath sight-size measuring, not a replacement for it.
For comic & manga artists
Consistency across panels is everything, and the head canon is how you keep a hero the same height from page to page. Heroic figures sit at 8.5–9 heads; pick the number, lock it into your model sheet, and the overlay enforces it so the protagonist doesn't shrink in the long shot. Stylised manga often shifts the canon by age and archetype deliberately.
For character designers
The head count is a character decision: a 4-head chibi, a 6-head everyman, an 8.5-head hero, a 3-head mascot all read instantly as different "kinds" of being. Specify the canon in the design brief and the overlay holds it across turnarounds and expression sheets, keeping silhouette and scale on-model.
For educators
The head canon is the first proportion lesson worth teaching because it is concrete and self-correcting: students measure with dividers, count heads, and immediately see why their figure looked wrong. Pair it with the pubis-midpoint rule and the comparison of real (7.5) versus idealised (8) proportion to teach both observation and the history of stylisation in one exercise.
"For the human body is so designed by nature that the face, from the chin to the top of the forehead, is a tenth part of the whole height; the foot is one sixth; and other members have their own symmetrical proportions."
Vitruvius, De Architectura, Book III (c. 15 BC)2
Frequently asked questions
What is the 8-head canon?
The 8-head canon is a system that builds the standing figure as a stack of eight equal head heights — head, nipples, navel, pubis, thigh, knee, calf, sole. It is an idealised figure rather than a measured average, used in academic figure drawing for its graceful, slightly heroic read. Lysippos slimmed the classical figure toward eight heads and 19th-century academies fixed it as the teaching standard.
Why is the figure measured in head heights?
Head height is the most stable internal unit on a body — it doesn't change with pose, clothing, or foreshortening the way limb lengths appear to. Measuring the whole figure in head heights lets an artist construct accurate proportions on any pose using the head itself as the master ruler. Polykleitos formalised this modular approach in the 5th century BC.
How many heads tall is the human body really?
Real adults average about 7 to 7.5 head heights. The 8-head canon is a deliberate idealisation that reads as graceful and heroic. Classical Greek work used roughly 7 (Polykleitos) to 8 heads (Lysippos); 19th-century academies settled on 8; fashion illustration stretches to 9 or more. The overlay toggles between 7, 7.5, 8, and 9.
Where do the landmarks fall in the 8-head canon?
Head 1 is the head; line 2 the nipples; line 3 the navel; line 4 the pubic bone, which is the body's midpoint; line 5 the upper thigh; line 6 the knee; line 7 the calf; line 8 the soles. Shoulders span about 2 head-widths, hips about 1.5. The overlay marks these automatically.
Do male and female figures use the same proportions?
Total height is the same canon, but distribution differs: female figures typically have a higher waist, narrower shoulders relative to wider hips, and a slightly longer leg-to-torso ratio; male figures are broader at the shoulders. The overlay includes a toggle that shifts these landmark widths.
Why is the body's midpoint not the waist?
Because the legs are long. On a standing adult the halfway point between crown and sole falls at the pubic bone, not the navel or waist as people expect. This is one of the most useful proportion facts — getting the midpoint right fixes most figures that look "off."
Who created the figure-proportion canon?
Polykleitos of Argos (5th century BC) wrote the first known treatise, The Canon, embodied in his Doryphoros. Lysippos slimmed it to 8 heads, Vitruvius transmitted it to Rome, Leonardo restated it in Vitruvian Man, and Andrew Loomis updated it for modern illustration in 1943.
How tall are children in head heights?
Children have proportionally larger heads. A newborn is roughly 4 heads tall, a toddler about 4 to 5, a six-year-old about 6, and a twelve-year-old around 6.5, reaching the adult 7.5 by the late teens. Drawing a child with adult proportions is the fastest way to make them read as a tiny adult.
Does the overlay work on foreshortened or seated poses?
Only loosely. The head-height ladder assumes an upright, frontal figure. In strong foreshortening or seated poses the apparent head height changes along the body, so the divisions become a rough guide that needs manual interpretation rather than a strict ruler.
