Object Drawing Lessons
Contour drawing captures the outer edge and key internal edges of a form without shading. For a bishop chess piece, the silhouette is defined by the rounded top, the pointed mitre, the narrow collar, and the stepped base. This lesson teaches a repeatable edge-order method: start at the top, move down one side, cross the base, and return up the other side. You will use a simple convention: draw only visible edges as continuous lines, and treat the x-height (baseline to midline of lowercase letters) as a proportion reference for the collar width. Letter styles vary, so use the convention as a guide, not a universal standard. All measurements are hypothetical examples; measure your own reference or drawing surface. The goal is a clean, checkable contour that a viewer can recognize as a bishop.

Edge order for a bishop contour
A bishop chess piece has four main contour zones: the rounded finial (top knob), the mitre (pointed head), the collar (narrow neck ring), and the base (stepped foot). Draw them in order so you do not lose proportion. First, mark the topmost point and the bottommost point of the piece. Second, draw the finial as a small circle or oval. Third, draw the mitre as a pointed arch that widens downward. Fourth, draw the collar as a short horizontal band narrower than the mitre. Fifth, draw the base as a trapezoid with a flat bottom. Finally, connect the zones with smooth lines and check that left and right sides are roughly symmetrical.
Use a light pencil for the first pass. Keep the line continuous where possible; if you lift the pencil, restart at the same point. Do not shade or fill. The contour is the edge, not the surface. For the mitre, the point should sit above the collar and below the finial. For the base, the widest part is usually the bottom step. If your reference shows a different order, follow the visible edges, but keep the top-to-bottom sequence for consistency.
- Mark top and bottom extremes with two small dots.
- Draw the finial as a small oval centered on the vertical axis.
- Draw the mitre as a pointed arch from the finial down to the collar.
- Draw the collar as a narrow horizontal band.
- Draw the base as a trapezoid with a flat bottom edge.
- Connect the zones with smooth side lines and check symmetry.
Proportion checks using a simple convention
Define a unit: the collar width equals one x-height (baseline to midline of a lowercase letter in your normal handwriting). This is a convention, not a universal standard. Measure your own x-height on the paper with a ruler; for example, if your x-height is 5 mm, then the collar is about 5 mm wide. The mitre height is about three x-heights, the finial diameter about one x-height, and the base width about four x-heights. These numbers are hypothetical examples; adjust to your reference. Check that the mitre point is centered above the collar and that the base is wider than the mitre.
Use a ruler only for checking, not for drawing curves. After drawing, measure the widest part of the base and the widest part of the mitre. The base should be wider. Measure the collar width and compare it to your x-height. If the collar is too wide, narrow it. If the mitre is too short, extend the point upward. Keep all units consistent (millimeters or centimeters).
- Measure your x-height on the paper and record it.
- Check collar width against one x-height.
- Check mitre height against three x-heights.
- Check base width against four x-heights.
- Adjust only the zone that fails the check.
Line quality and valid alternatives
Contour lines should be clean and readable. A slightly wobbly line is acceptable if the edge order and proportions are correct. You may use a single continuous line or short overlapping strokes; both are valid if the contour is clear. Do not add shading, cross-hatching, or chessboard context. The bishop should stand alone in the frame. If your reference shows a decorative band on the mitre, you may include it as an internal contour line, but keep it simple.
Valid alternatives include a rounded finial instead of an oval, a slightly curved base instead of a straight trapezoid, and a mitre with a small notch at the point. These are acceptable if the overall silhouette remains recognizable and the edge order is followed. The rubric rewards clear edges and consistent proportions, not a single universal shape.
- Draw the contour without shading.
- Keep the bishop centered in the frame.
- Include only visible edges; omit hidden edges.
- Check that the silhouette reads as a bishop from a distance.
Worked example
A reference bishop has a collar width of 6 mm. Using the convention, estimate the mitre height and base width, then describe the edge order for drawing the contour.
Worked answer
Mitre height is about 3 x 6 mm = 18 mm. Base width is about 4 x 6 mm = 24 mm. Edge order: mark top and bottom, draw finial oval, draw mitre arch down to collar, draw collar band, draw base trapezoid, connect sides, then check symmetry and proportions.
Four practice exercises
Exercise 1
A bishop reference has a collar width of 5 mm. Using the convention, calculate the expected mitre height and base width. Then list the first three edges to draw in order.
Show answer and check
Mitre height = 3 x 5 mm = 15 mm. Base width = 4 x 5 mm = 20 mm. First three edges: top and bottom marks, finial oval, mitre arch.
Why: The convention sets mitre height at three x-heights and base width at four x-heights, with collar width equal to one x-height. Edge order starts at the top and moves down.
Check: Verify arithmetic: 3 x 5 = 15 and 4 x 5 = 20. Check that the listed edges follow the top-to-bottom sequence.
Exercise 2
A learner draws a bishop with a collar width of 8 mm, a mitre height of 12 mm, and a base width of 20 mm. Using the convention, identify which proportion is most off and suggest one fix.
Show answer and check
The mitre height is most off: expected 3 x 8 = 24 mm, but drawn 12 mm. Fix: raise the mitre point to about 24 mm above the collar.
Why: Collar width sets the unit. Expected mitre height is three times the collar width. The drawn mitre is half the expected height, so it is the largest error.
Check: Compute 3 x 8 = 24 and compare to 12: the mitre is 12 mm shorter than expected, which is 12/24 = 50% short. Check base width: expected 4 x 8 = 32 mm, drawn 20 mm, also 12 mm short, which is 12/32 = 37.5% short. Both are 12 mm short in absolute terms, but the mitre is proportionally more off (50% vs 37.5%), so it is the largest proportional error.
Exercise 3
Describe how to draw the contour of a bishop whose finial is a small circle, mitre is a pointed arch, collar is a narrow band, and base is a trapezoid. Include the edge order and one symmetry check.
Show answer and check
Mark top and bottom. Draw the finial circle centered on the vertical axis. Draw the mitre arch from the finial down to the collar. Draw the collar band. Draw the base trapezoid with a flat bottom. Connect the sides. Symmetry check: measure the horizontal distance from the vertical axis to the left and right edges at the collar; they should be equal within about 1 mm.
Why: The edge order keeps the top-to-bottom sequence and prevents merging zones. The symmetry check uses a measurable distance on both sides.
Check: Confirm the order matches finial, mitre, collar, base, sides. Measure left and right collar distances with a ruler and compare.
Exercise 4
A learner's bishop contour has a base width of 24 mm and a mitre width of 18 mm. The collar width is 6 mm. Using the convention, state whether the base and mitre widths are acceptable, and give one reason.
Show answer and check
Base width is acceptable: expected 4 x 6 = 24 mm. Mitre width is not directly set by the convention, but it should be narrower than the base; 18 mm is narrower than 24 mm, so it is acceptable. Reason: the base is wider than the mitre and the base matches the expected width.
Why: The convention sets base width at four x-heights. The mitre width is not fixed, but the silhouette requires the base to be wider. Both conditions are met.
Check: Compute 4 x 6 = 24 and compare to the drawn base. Compare 18 mm and 24 mm to confirm the base is wider.
Common mistakes
- Drawing the base wider than the mitre but forgetting the collar, so the mitre merges into the base. Draw the collar as a distinct narrow band between mitre and base; check its width against one x-height.
- Making the mitre point too low, so the piece looks like a pawn. Raise the mitre point to about three x-heights above the collar and recheck the top-to-bottom order.
- Adding shading or filling the contour. Erase shading and keep only edge lines; the task is contour only.
- Using inconsistent units when checking proportions. Measure all lengths in the same unit (for example, millimeters) and record them before adjusting.
Self-check rubric
- Edge order followed: finial, mitre, collar, base, then connecting sides.
- Collar width is close to one measured x-height (within about 1 mm for a 5 mm x-height).
- Mitre point is centered above the collar and clearly pointed.
- Base is wider than the mitre and has a flat bottom edge.
- Contour lines are clean and readable; no shading or filling.
- Bishop is centered in the frame and recognizable from a distance.
- Valid alternatives (rounded finial, slight curve in base) are accepted if proportions and edge order are correct.
Questions and answers
What is the x-height convention?
It is the distance from the baseline to the midline of a lowercase letter in your normal handwriting. Use it as a repeatable width unit for the collar. Measure your own x-height; do not assume a standard value.
Can I use a ruler to draw the curves?
Use a ruler only for checking proportions. Draw curves freehand so the contour stays natural. A slightly irregular line is acceptable if the edge order is correct.
Do I need to draw the chessboard?
No. The brief excludes chessboard context. Draw only the bishop silhouette in a blank frame.
What if my reference bishop has a different shape?
Follow the visible edges of your reference, but keep the top-to-bottom edge order and the proportion checks. The convention is a guide, not a universal standard.
