Object Drawing Lessons
Posture drawing is the skill of seeing how a body organizes itself around gravity. Before adding detail, you need to notice where the weight sits, which direction the torso tips, and how the limbs counterbalance. This lesson uses a planned printable 3x3 grid of simple silhouettes—three standing, three sitting, three leaning—each with a blank redraw box and a balance-line guide. You will practice reading the line of gravity, marking the base of support, and reproducing the pose with a consistent convention: keep the balance line vertical, mark the base of support as a horizontal segment, and allow line quality and stroke order to vary. All measurements are hypothetical examples; measure your own equipment and label any numbers you choose.

Reading the Balance Line and Base of Support
Every posture in the grid can be read as a relationship between two marks: the balance line (a vertical dropped from the body's center of mass) and the base of support (the area under the feet or seat). In a standing pose, if the balance line falls inside the feet, the pose is stable; if it falls outside, the body is leaning or falling. In a sitting pose, the base may be the seat alone or the seat plus any feet that carry weight; mark whichever contacts actually bear weight and state which you used. In a leaning pose, the base may be one foot or a hand on a wall.
Before redrawing any silhouette, trace the balance line on the reference and mark where it meets the ground or seat. Then mark the base of support as a short horizontal segment. The distance between these two marks tells you how much weight shift the pose contains. A small offset means a subtle shift; a large offset means a dramatic lean. Use the same units for all measurements—for example, measure in millimeters on your printed page, and label any chosen values as hypothetical.
- Place the grid so the balance-line guide is visible beside each silhouette.
- Trace the vertical balance line from the top of the head through the torso to the ground or seat.
- Mark the base of support as a horizontal segment under the feet or seat.
- Measure the horizontal offset between the balance line and the center of the base; record it in millimeters as a hypothetical example.
- Note whether the offset is small (under 10 mm), medium (10–25 mm), or large (over 25 mm) on your printed page.
Redrawing the Silhouette in the Blank Box
The blank box beside each silhouette is for a freehand redraw, not a tracing. Start by placing the balance line and base of support first, then build the silhouette around them. Use the vertical balance line and the base of support as proportion guides; line quality and stroke order may vary, and there is no single correct way to draw the contour. The goal is to match the weight shift, not to copy every edge.
Work from the ground up. Draw the base of support, then the feet or seat contact, then the knees or hips, then the torso, and finally the head and arms. Check your redraw by comparing the offset between your balance line and base to the reference offset. If your offset differs by more than about 5 mm on the printed page (a hypothetical tolerance), adjust the torso or hips until the weight shift matches.
- Draw the balance line and base of support in the blank box first.
- Block the feet or seat contact as simple shapes.
- Add knees or hips, then torso, then head and arms, keeping the balance line vertical.
- Compare your offset to the reference offset; adjust if the difference exceeds 5 mm (hypothetical).
- Label your drawing with the offset value and the base width in millimeters.
Comparing Standing, Sitting, and Leaning Postures
The 3x3 grid separates three posture families. Standing poses usually have a narrow base and a balance line near the feet; sitting poses have a wider base that includes the seat; leaning poses have a base that may be a single foot or a hand contact. When you compare rows, ask: where is the balance line relative to the base, and how does the torso angle change?
A useful comparison is to measure the horizontal distance from the balance line to the nearest edge of the base. In a stable standing pose this distance is positive on both sides; in a leaning pose it may be zero or negative on one side. Record these distances in a small table beside each redraw. Use consistent units and label all numbers as hypothetical examples measured on your own printout.
- For each silhouette, record the base width and the balance-line offset.
- Compare the three standing poses: which has the largest offset?
- Compare sitting poses: does the balance line fall inside the seat area?
- Compare leaning poses: which side of the base has zero or negative clearance?
- Write one sentence per pose describing the weight shift in plain language.
Using the Rubric to Check Your Redraws
The rubric below is designed to accept valid alternatives. Because letter styles and line quality vary, the rubric focuses on observable relationships: balance line placement, base of support, offset measurement, and consistency of units. A redraw can be stylistically different from the reference and still pass if the weight shift is preserved.
Before submitting, check each redraw against the rubric. If a criterion is not met, revise the balance line or base first, then adjust the silhouette. Keep your measurements in the same units throughout, and note any hypothetical values you chose so a reviewer can reproduce your check.
- Verify the balance line is vertical and passes through the torso.
- Verify the base of support is marked and measured.
- Verify the offset is recorded with units.
- Verify the redraw preserves the weight shift within the stated tolerance.
- Verify all numerical values are labeled as hypothetical examples.
Worked example
A standing silhouette on a printed page has a base of support 40 mm wide. The balance line falls 8 mm to the left of the base center. Redraw the pose in a blank box and check the offset.
Worked answer
Draw a vertical balance line and a 40 mm horizontal base. Place the balance line 8 mm left of the base center. Build the silhouette so the torso leans slightly left and the right foot bears more weight. Measure your redraw: the offset should be 8 mm plus or minus 5 mm (hypothetical tolerance). Record the offset and base width in millimeters.
Four practice exercises
Exercise 1
A sitting silhouette has a seat base 60 mm wide and a balance line 12 mm right of the seat center. Redraw the pose and state the offset you measure.
Show answer and check
The redraw should show a vertical balance line 12 mm right of the seat center, with the torso shifted slightly right. Measured offset should be 12 mm plus or minus 5 mm (hypothetical).
Why: The balance line falls inside the seat base, so the pose is stable but shifted right. The redraw must preserve that offset.
Check: Measure the horizontal distance from your balance line to the seat center; compare to 12 mm with a 5 mm hypothetical tolerance.
Exercise 2
A leaning silhouette has one foot as its base, 25 mm wide, and the balance line falls exactly on the outer edge of the foot. Redraw the pose and describe the weight shift.
Show answer and check
The redraw should show the balance line touching the outer edge of the single-foot base, with the body leaning toward that edge. The weight shift is at the limit of stability for that base.
Why: When the balance line meets the edge of the base, the pose is at the boundary between stable and falling. The redraw must show that edge contact.
Check: Check that your balance line touches the outer edge of the 25 mm base and that no part of the line falls outside the base.
Exercise 3
Two standing silhouettes are side by side. One has a base 30 mm wide with a 4 mm offset; the other has a base 50 mm wide with a 20 mm offset. Which pose shows a larger weight shift, and by how much?
Show answer and check
The second pose shows a larger weight shift: 20 mm versus 4 mm, a difference of 16 mm (hypothetical values).
Why: The offset measures the horizontal distance between the balance line and the base center. A larger offset means a larger weight shift, regardless of base width.
Check: Subtract the smaller offset from the larger: 20 mm minus 4 mm equals 16 mm. Confirm both values are in millimeters.
Exercise 4
A leaning pose uses a hand on a wall as part of its base. The foot base is 20 mm wide and the hand contact adds 30 mm to the base on one side. The balance line falls 10 mm inside the combined base from the hand side. Redraw the pose and mark the combined base.
Show answer and check
The redraw should show a combined base of 50 mm (20 mm foot plus 30 mm hand extension) and a balance line 10 mm inside the hand-side edge. The pose is stable because the line falls within the combined base.
Why: The hand contact extends the base of support, so the balance line can fall outside the foot base but still inside the combined base.
Check: Measure the combined base width (should be 50 mm) and the distance from the balance line to the hand-side edge (should be 10 mm plus or minus 5 mm, hypothetical).
Common mistakes
- Tracing the silhouette instead of redrawing it freehand. Cover the reference with a blank sheet and redraw from observation, using only the balance line and base marks as guides.
- Drawing the balance line at an angle to match the torso lean. Keep the balance line vertical; the torso may lean, but the line of gravity does not.
- Measuring offsets in mixed units (for example, centimeters and millimeters). Choose one unit, such as millimeters, and convert all measurements before comparing.
- Assuming a leaning pose is unstable because the balance line is outside the feet. Check for a hand or wall contact that extends the base of support; the balance line may fall inside the combined base.
Self-check rubric

- Offset between balance line and base center is recorded with units.
- Redraw preserves the weight shift within the stated hypothetical tolerance.
- All numerical values are labeled as hypothetical examples.
- Redraw is freehand, not a tracing, and preserves the vertical balance line and base of support.
Questions and answers
Do I need the printable grid to do this lesson?
The grid is planned but not yet built. You can practice by drawing your own 3x3 grid of simple silhouettes on paper and adding a vertical balance line beside each.
How do I choose the base of support for a leaning pose?
Look for every contact that carries weight: feet, seat, and any hand or shoulder on a wall. Mark the full horizontal span of those contacts as the base, then check whether the vertical balance line falls inside that span.
Are the millimeter values in the lesson real standards?
No. All numerical values are hypothetical examples. Measure your own printed page or drawing and label your chosen values as hypothetical.
Can a redraw pass the rubric if it looks different from the reference?
Yes. The rubric checks balance line placement, base of support, offset measurement, and unit consistency, not stylistic similarity.
