The finished result: How to Draw a Skeleton

A skeleton looks like the hardest thing you could pick to draw. Two hundred bones, all of them odd shapes. The trick is that you never draw two hundred bones at the start. Dan Beardshaw builds his front-view skeleton from a handful of simple blocks on a measured grid, and only adds the real bone detail once the proportions are locked in. That is the method here.

You need a pencil, an eraser, a ruler and a sheet of paper. Plan on an hour for the simplified skeleton and another hour or two if you go on to the detailed version.

Why the eight head-unit grid matters

An adult figure is about eight heads tall and two heads wide from the front. Rule that grid before you draw anything and every bone has a place to land. The skull fills unit one. The rib cage sits in units two and three. The pelvis takes unit four. Wrists land around unit five, knees at the bottom of unit six. When a skeleton drawing looks wrong, it is almost always because an arm or leg is too long, and the grid stops that before it happens.

Simplified shapes first, detail second

Each block in this method is a real shape, not a stick figure. The rib cage is an upside-down egg. The pelvis is a tapered bucket with a scoop cut from the front. Joints are circles. Because the blocks already follow the real forms, the detailed bones slot straight into them later. Keep these early lines light. You will draw over them, and dark construction lines are hard to erase.

Dan draws his simplified skeleton on one page, then traces a light copy onto the facing page to develop the detail. A light box or a bright window makes that easy. Tracing paper works too.

How much detail do you need?

Less than you think. For figure drawing, the simplified skeleton does most of the work: it gives you proportions and where each joint bends. Draw every rib and vertebra when the skeleton is the subject, like a study page or a Halloween illustration. For the head, our guide on how to draw a skull takes the cranium, eye sockets and teeth further than this page does. For the fingers, see how to draw hands.

Drawing a skeleton for Halloween

A clean front-view skeleton works for cards, costume designs, window art and classroom posters. Go over your final lines with a fine black pen, let the ink dry, then erase the pencil grid. On black card, trace the finished skeleton in white gel pen or white pencil. Pair it with a cartoon ghost for a full Halloween scene.

Common skeleton drawing problems

  • The arms look too short. The wrists sit below the hip line, not at the waist. Check against unit five.
  • The legs look stiff. The femurs angle inward from the hips to the knees. Straight vertical thigh bones read as a robot.
  • The spine looks like a pipe. Make each vertebra a little larger as you go down toward the pelvis.
  • The page is smudged. Rest your hand on a scrap of paper and work from the top down.

What you'll need

Step-by-step guide

10 steps, about 16 minutes. Tap a picture to jump to that step. Your progress saves automatically.

Tick each step off as you go.

  1. Step 1: Rule an 8 Head-Unit Proportion Grid for the Skeleton Drawing

    Watch this step · 1:43

    Draw a vertical centre line down the page and split it into eight equal sections with a ruler. Each section is one head unit. Add a line either side so the grid is two units wide, one unit left of centre and one right. Divide the top unit into thirds as well. That grid is the measuring stick for every bone that follows.

    Tip:

    Press lightly. The grid is scaffolding, and you will want to erase most of it at the end.

    Back to all steps

  2. Step 2: Draw the Skeleton Skull as a Circle and Jaw in the Top Unit

    Watch this step · 2:30

    In the top unit, draw a circle across the upper two thirds for the cranium. Use the bottom third for the jaw, a squarer block that tapers down to the chin. Leave out the eye sockets and teeth for now. This head is only a placeholder, and it sets the size of everything below it.

    Tip:

    Draw a light cross through the circle. It marks the centre of the face and makes the features easy to place later.

    Back to all steps

  3. Step 3: Box In the Skeleton Rib Cage Below the Neck

    Watch this step · 3:48

    Drop down one third of a unit for the neck and the top of the shoulders. Mark a box about one and a third units tall and one and a third wide. Inside it, draw the rib cage as an upside-down egg, wider at the top and narrowing to the waist. Add the arched opening at the bottom where the ribs part.

    Tip:

    Think of the rib cage as a solid form, not a set of lines. It makes drawing it from other angles much easier later.

    Back to all steps

  4. Step 4: Sketch the Skeleton Pelvis as a Tapered Bucket Shape

    Watch this step · 4:28

    The next unit down holds the pelvis. Draw a box about the same width as the rib cage, then a bucket inside it that narrows toward the bottom. Cut a scooped section out of the front. It looks crude now, but those planes line up with the hip bones you will draw over it later.

    Tip:

    The pelvis is the hardest block to get right. If it looks off, leave it rough and come back once the legs are in.

    Back to all steps

  5. Step 5: Add the Skeleton Shoulder Girdle and Upper Arm Bones

    Watch this step · 6:20

    Draw the clavicles as two tubes running out from the top of the rib cage. Add the shoulder blades as curved triangles tucked behind. At the end of each clavicle, draw a small circle for the shoulder joint. From there, run the humerus down to about the bottom of unit three.

    Tip:

    The humerus is a simple bone. Draw it as a slim tube with a knob at each end and move on.

    Back to all steps

  6. Step 6: Draw the Forearm Bones and Simple Skeleton Hands

    Watch this step · 7:24

    Below the elbow, draw two bones side by side, the radius and the ulna. In this palms-forward pose they run parallel and end a little below the pelvis. Block the palm as one shape, then add the fingers as short blocks. At this size a simple hand reads better than every knuckle.

    Tip:

    Your hand should reach about halfway down unit five. If it stops at the hip line, the arm is too short.

    Back to all steps

  7. Step 7: Draw the Skeleton Leg Bones, Knee Caps and Feet

    Watch this step · 8:50

    Put a circle at each side of the pelvis for the hip joint. Draw the femurs angling inward to the bottom of unit six. Add a small upside-down triangle for each knee cap, then the tibia and fibula down to a third of a unit above the bottom line. Finish with an ankle circle and a wedge for each foot.

    Tip:

    The femur is the longest bone in the body. If the thighs look short next to the shins, redraw them.

    Back to all steps

  8. Step 8: Connect the Skull, Rib Cage and Pelvis With the Spine

    Watch this step · 9:46

    Finish the pelvis now that the legs show you where it needs to sit. Then draw the spine from the base of the skull, down through the rib cage, into the back of the pelvis. Make it thicker as it goes down, ending in the triangular sacrum. That is your full simplified skeleton.

    Tip:

    Stop and check proportions against the grid here. Fixing a long arm now is far easier than after the detail goes on.

    Back to all steps

  9. Step 9: Draw the Detailed Skull and Ribs Over the Simplified Skeleton

    Watch this step · 11:48

    Trace a light copy of your simplified skeleton onto a fresh page, or work over the original. Start at the top. Add eye sockets, nose and teeth to the skull, then the collarbones and sternum. Draw the ribs one pair at a time, curving round the egg shape. Press harder now so the final lines stand out.

    Tip:

    Keep a reference photo or a model skeleton next to you for the ribs. Nobody draws them from memory.

    Back to all steps

  10. Step 10: Refine the Skeleton Pelvis, Vertebrae and Hand Bones

    Watch this step · 13:10

    Draw each vertebra as a small block, larger toward the pelvis. Shape the hip bones inside your bucket. Refine the radius and ulna, then the wrist bones and each finger joint. Work down the femurs, knees, shins and feet the same way. Mirror each side as you go so the skeleton stays even.

    Tip:

    Erase the grid and leftover construction lines last, once every bone is inked or darkened.

Key takeaways from How to Draw a Skeleton

5 questions, answers, and one-line explanations. Tap to expand.

  1. 1.About how many heads tall is an adult figure?

    Answer: About eight heads

    An eight-unit grid gives every bone a place to land.

  2. 2.Why keep the early construction lines light?

    Answer: Dark lines are hard to erase later

    You draw over these lines, so they need to disappear afterwards.

  3. 3.Where should the wrists fall on a standing skeleton?

    Answer: Just below the hip line

    Arms that stop at the waist are the most common proportion mistake.

  4. 4.How should the thigh bones run from the front?

    Answer: Angled inward from hips to knees

    Straight vertical femurs make the figure look stiff and robotic.

  5. 5.How should the vertebrae change down the spine?

    Answer: Grow a little larger toward the pelvis

    Drawing them all the same size makes the spine look like a pipe.
