How to Draw Anime Proportions & Head-to-Body Ratio: A Step-by-Step Guide by Japanese Pro Artists

The short answer: Count how many heads stack up to your character's full height. Around 7 heads reads as an adult, 6 as a teen, 5 as a kid of 4 to 8, and 4 as a toddler. Then put the crotch in the right place: halfway down the body for 5 heads and up, halfway between the chin and the feet for 4 heads and under.

If your kid characters look like tiny adults, or your adults look oddly young, the head count is almost always the reason. This guide walks through the head-count chart for girls and boys, the four body landmarks that keep legs and arms the right length, and what changes from babies to adults.

Step 01 · Head count for girls

How many heads tall should an anime girl be at each age?

The fewer heads, the younger she looks: 4 heads for ages 1 to 3, about 7 heads for 16 and up.

Head count is just the full height divided by the height of the head, from the top of the skull to the tip of the chin. That one number does most of the work of telling the viewer how old someone is. A small head count pushes a character toward cute and childlike. A big one pushes her toward grown-up.

Use the chart as a starting point: 4 heads for ages 1 to 3, 5 heads for 4 to 8, 6 heads for 9 to 15, 7 heads for 16 through adulthood, and 8 heads for a long-legged model figure. Real growth works the same way. Kids sit at 4 to 5 heads, girls shoot up to about 6 heads around age 10, and growth stops near 15, which lands an adult at about 7 heads.

These numbers are a guide, not a law. People vary, and anime and manga bend them all the time. Real toddlers are 3 to 4 heads, but drawing a baby at about 2 heads is a common way to make it read as extra cute. It's the same trick that turns a 7-head lead into a 2-head chibi for an omake strip.

Red-pen checkPut your character next to a stack of heads before you add any detail. The top of the head and the tip of the chin should sit between two lines, not halfway across one.

Step 02 · Head count for boys

Do anime boys use the same head-count chart?

Yes, the same chart works for boys; the difference shows up in the shoulders and the crotch height.

Boys follow the same steps: 4 heads for ages 1 to 3, 5 for 4 to 8, 6 for 9 to 15, 7 from 16 up, and 8 for a model figure. Boys hit their big growth spurt a little later than girls, around 11 and a half, and finish growing around 16.

Where boys pull away is the frame. From middle school on, the shoulders get wider than the face and the arms and legs look sturdier. A grown man's shoulders get wider again, and his crotch sits a little higher than a teen boy's. When a man and a woman share a panel, give him a bit of extra height too. The average Japanese man is about 13 cm taller than the average Japanese woman.

Red-pen checkIf your boy looks younger than you meant, check the shoulders first. From 5 heads up, they should be wider than the head.

Step 03 · Crotch, waist, elbow, fist

Where do the crotch, waist and elbows go?

Find the crotch first, then the waist halfway up to the chin; the elbow and fist line up with them.

Leg length is where most bodies go wrong, so place the crotch before anything else. At 5 heads and up, the crotch sits at exactly half the full height, so the legs are as long as everything above them. At 4 heads and under, measure from the chin instead: the crotch sits halfway between the chin and the feet. That's why little kids look short-legged.

Next comes the waist, halfway between the chin and the crotch. Arms hang off these two marks. With the arms down, the elbow lines up with the waist, and the fist (the knuckle at the bottom of the hand) lines up with the crotch. If the hands hang below the crotch, the arms are too long.

Red-pen checkDraw a quick line at the crotch and one at the waist before you sketch the arms. If the elbow misses the waist line, fix the upper arm, not the hand.

Step 04 · A boy and a girl at each age

How do kids, teens and adults differ besides height?

Each age changes the head size, the shoulder width and the leg length together, so change all three at once.

Up to about age 20, a body changes by growing. Here's a boy and a girl at five ages, with what to watch at each one.

Babies

3 to 4 heads

Boys and girls look almost the same at this age, so tell them apart with hairstyle and clothes. This is when the head is biggest compared to the body. Narrow shoulders, a short neck, short arms and legs, and a slightly round body all read as baby. A 2- to 3-head chibi look works too.

You can skip the neck. Up to 3 heads, draw the head wider than the shoulders.

Kindergarten

4 to 5 heads

The head barely grows from babyhood, but the body shoots up and the arms and legs get longer. A kid this age stands a little shorter than an adult's waist. Boys and girls are still built alike. Keep the outline round and the neck short, and make the top of the head to the crotch longer than the crotch to the heel.

Make the head and the shoulders about the same width. Slightly big hands and feet help the balance.

Elementary school

5 to 6 heads

Growth slows in the early grades, then height jumps around ages 10 to 12. The shoulders grow until they match the head, the legs stretch until the top of the head to the crotch equals the crotch to the heel, and the neck gets longer. In the early grades boys and girls still look alike, so hairstyle and clothes do the work. Near puberty, girls slowly start to look more grown-up.

From 5 heads up, draw the shoulders wider than the head.

Middle and high school

6 to 7 heads

Girls near the peak of their growth around 15, and their bodies get a little softer and rounder. Boys get sturdier shoulders, arms and legs from middle school on; think of an upside-down triangle and keep the shoulders wider than the face. Add a few chest and upper-stomach muscle lines. Draw teens a little shorter than adults, and don't push the curves or the muscle too hard. They should still look young.

The closer to 6 heads, the more they look like real middle and high schoolers.

Adults

7 heads

Women stop growing around 18. Watch the line from the waist to the thighs: a narrow waist and fuller hips, with an overall look that's slimmer than a teen's. Think elegant, not cute. Men stop growing around 20, when bone and muscle reach their peak. Widen the shoulders to match, and put the crotch a little higher than on a teen boy.

Use about 7 heads as your default for grown-up characters.

Red-pen checkDon't shrink an adult to make a kid. Make the head bigger compared to the body, the shoulders narrower and the legs shorter, all at the same time.

Teen vs adult: what actually changes

Both pairs are close to 7 heads. The difference is in the build: wider shoulders and a higher crotch for the man, a narrower waist and fuller hips for the woman.

Teens (6 to 7 heads): softer shapes, shoulders only a little wider than the face.

An anime adult woman and adult man, about 7 heads tall

Adults (7 heads): broad shoulders on the man, a clear waist-to-hip curve on the woman.

Where people usually get stuck

My kids look like tiny adults.

You probably scaled down an adult. Kids need a bigger head compared to the body, shoulders no wider than the head at 4 heads and under, and the crotch halfway between the chin and the feet.

The legs look too short (or way too long).

Check the crotch. From 5 heads up it belongs at exactly half the full height. Move the crotch, and the legs fix themselves.

The arms hang past the hips.

With the arms down, the elbow should line up with the waist and the fist with the crotch. Hands that reach past the crotch mean the arms are too long.

Anime proportions FAQ

What does head-to-body ratio mean in anime?

It's how many head heights fit into a character's full height, measured from the top of the head to the tip of the chin. A 7-head character is seven heads tall. Artists use it to make a character read as the right age.

How many heads tall is an anime adult?

About 7 heads is the usual default for adults. An 8-head figure reads as a tall, long-legged model type. Teens sit around 6 to 7 heads, kids around 4 to 6, and babies around 3 to 4.

Where should the legs start on an anime character?

At 5 heads and up, the crotch sits at half the full height, so the legs make up the lower half of the body. At 4 heads and under, the crotch sits halfway between the chin and the feet, which gives little kids their short legs.

How do I get feedback on my anime proportion drawings?

When you join an Anime Art Academy course, a professional Japanese artist gives you personal advice and draws red-line corrections directly on your drawing. There is no limit on how many times you can submit. The only rule: post one drawing at a time, and wait for your teacher's reply before posting the next.
