Object Drawing Lessons
This lesson teaches a repeatable method for drawing sword shapes on graph paper. You will plot a silhouette by counting grid squares, apply a shading convention that treats light as coming from the upper left, and verify proportions with simple arithmetic. The focus is the sword silhouette and its shading on grid squares; weapon anatomy labels and combat scenes are outside this task. All measurements use grid squares as the unit. Keep the plotted silhouette and tone counts consistent; labels are optional.

Plotting the silhouette on grid squares
Begin by choosing a total length in grid squares, for example 12 squares, and a blade width in grid squares, for example 2 squares. These numbers are hypothetical examples; measure your own paper and choose values that fit. Mark the tip, the blade edges, the guard, and the grip as coordinate pairs counted from a single origin square. Keep every edge on a grid line or a clear half-square so the silhouette is checkable.
A sword silhouette has four zones: tip, blade, guard, and grip. Plot the blade first as a long rectangle or tapered polygon, then add the guard as a short crossbar, then the grip as a narrower rectangle. The tip can be a triangle occupying one or two squares. Count squares along each zone and record the counts so you can check them later.
- Choose an origin square and label it (0,0) in pencil.
- Decide total length and blade width in grid squares; write these numbers beside the grid.
- Plot the blade edges as straight lines between counted coordinates.
- Add the guard as a crossbar whose width is a whole number of squares.
- Add the grip and tip, then count squares in each zone to confirm the totals.
Shading convention and grid alignment
Use one explicit convention: light comes from the upper left. Surfaces facing upper left stay light; surfaces facing lower right receive one or two shading layers. Apply shading in whole grid squares or half-squares so the pattern is countable. Do not blend across grid lines; keep each shaded cell either light, mid, or dark. This makes the shading checkable by counting cells.
Shade the lower-right edge of the blade with mid tone and the lower-right side of the guard with dark tone. Leave the upper-left blade edge light. The grip can receive a mid tone on its lower-right half. If you add a highlight, place it as a single light cell on the upper-left blade face. Record the number of light, mid, and dark cells so the balance can be checked.
- Mark the light direction with a small arrow in the corner of the page.
- Outline the silhouette in pencil before shading.
- Assign each cell one of three tones: light, mid, dark.
- Shade lower-right surfaces with mid or dark, keeping upper-left surfaces light.
- Count cells per tone and write the counts beside the drawing.
Checking proportions with arithmetic
Proportion checks use simple arithmetic in grid squares. If total length is 12 squares and blade length is 8 squares, then guard plus grip plus tip must equal 4 squares. If blade width is 2 squares and guard width is 6 squares, the guard is three times the blade width. Write these relationships as equations and verify them against your plotted coordinates.
A second check is symmetry: the guard should extend equally on both sides of the blade centerline. Count squares left and right of the centerline; the counts should match. For the tip, the triangle base should equal the blade width in squares. Any mismatch means a coordinate was miscounted, not that the drawing is wrong in style.
- Write total axial length = tip + blade + guard thickness + grip; guard width runs across the blade and is not added to axial length in squares.
- Verify guard width is a whole number of squares and symmetric about the centerline.
- Check tip base equals blade width in squares.
- Re-count coordinates for any zone that fails the arithmetic check.
Valid alternatives and style variation
Sword styles vary: straight or slightly curved blades, simple or cross guards, wrapped or plain grips. The convention allows any of these as long as the silhouette is plotted on grid squares and the shading follows the upper-left light rule. A title is optional; the rubric checks the plotted dimensions and the stated shading convention.
A valid alternative might use a tapered blade instead of a rectangle, or a rounded guard instead of a crossbar. The rubric checks consistency and countability, not a single universal shape. Record your chosen style in one sentence so the drawing can be reviewed against its own stated convention.
- State your sword style in one sentence before plotting.
- Keep all edges on grid lines or clear half-squares.
- Apply the same light direction throughout.
- Record tone counts and proportion equations for review.
Worked example
Plot a straight sword with total length 10 squares, blade width 2 squares, blade length 6 squares, guard width 4 squares, guard thickness 1 square, grip length 2 squares, and tip length 1 square. Shade with upper-left light and count tones.
Worked answer
Blade occupies 6 squares length by 2 squares width, giving 12 cells. Guard is 4 squares wide and 1 square thick, centered on the blade, giving 4 cells. Grip is 2 squares long and 1 square wide, giving 2 cells. Tip is a triangle with base 2 squares and height 1 square; count it as 1 cell for tone counting. Total length check: 6 + 1 + 2 + 1 = 10 squares. Guard symmetry: 2 squares left and 2 squares right of centerline. Shading with upper-left light: on the blade, the upper-left column of 6 cells stays light and the lower-right column of 6 cells is mid. On the guard, the 2 cells on the upper-left half stay light and the 2 cells on the lower-right half are dark. On the grip, the upper-left cell stays light and the lower-right cell is mid. The tip cell stays light. Tone counts: light = 6 + 2 + 1 + 1 = 10 cells; mid = 6 + 1 = 7 cells; dark = 2 cells. Total = 10 + 7 + 2 = 19 cells, matching 12 blade + 4 guard + 2 grip + 1 tip.
Four practice exercises
Exercise 1
Plot a sword with total length 12 squares, blade length 8 squares, blade width 2 squares, guard width 6 squares, guard thickness 1 square, grip length 3 squares, and tip length 1 square. The given numbers do not sum to the stated total; identify the mismatch, choose one corrected dimension, and plot the corrected sword. Then check the arithmetic and guard symmetry.
Show answer and check
Given zones: blade 8, guard 1, grip 3, tip 1. Sum = 8 + 1 + 3 + 1 = 13 squares, which exceeds the stated total of 12 by 1 square. Corrected plot: reduce the grip to 2 squares. Then blade 8 by 2 squares; guard 6 wide by 1 thick centered on the blade; grip 2 long by 1 wide; tip triangle base 2 height 1. Total check: 8 + 1 + 2 + 1 = 12 squares. Guard symmetry: 3 squares left and 3 squares right of the centerline. Shading with upper-left light: upper-left blade column light, lower-right blade column mid, lower-right guard half dark, upper-left guard half light, grip lower-right cell mid, tip cell light.
Why: The zones must sum to the stated total length. The original numbers sum to 13, so one zone must change by 1 square; reducing the grip from 3 to 2 squares gives a consistent total of 12. Symmetry is checked by counting squares on each side of the blade centerline.
Check: Re-add blade, guard, grip, and tip in squares and confirm the sum is 12. Count guard squares left and right of the centerline and confirm both are 3. Count light, mid, and dark cells and confirm they match the stated shading.
Exercise 2
A drawing has blade width 3 squares and guard width 8 squares. State the ratio. Plot a symmetric guard by placing the blade centerline on a grid line so the guard extends 4 squares on each side; count squares to verify symmetry. Then shade a blade of length 6 squares and width 3 squares with upper-left light and count tones.
Show answer and check
Guard width is 8 squares and blade width is 3 squares, so the guard is 8 ÷ 3 ≈ 2.67 times the blade width; state the ratio as 8:3. Place the blade centerline on a grid line. The blade is 3 squares wide, so its edges lie 1.5 squares left and 1.5 squares right of the centerline, on clear half-square lines. The guard is 8 squares wide, so it extends 4 squares left and 4 squares right of the centerline, with ends on grid lines. All edges lie on grid lines or clear half-squares. Blade is 6 squares long by 3 squares wide, so it contains 18 cells. Shading rule for this task: upper-left edge cells stay light, lower-right edge cells are mid, and interior cells remain light. With a 3-square-wide blade, the upper-left edge is 6 cells, the lower-right edge is 6 cells, and the interior column is 6 cells. Tone counts: light 12 cells (upper-left edge plus interior), mid 6 cells (lower-right edge), dark 0 cells. Total 18 cells.
Why: The ratio compares guard width to blade width as 8:3. An 8-square guard is even, so a grid-line centerline gives whole-square extensions of 4 squares on each side. The 3-square blade centered on the same grid line has edges on half-square lines, which the convention allows. Shading follows the stated upper-left light direction, with each cell assigned one tone.
Check: Confirm the ratio is 8:3 by comparing the two widths. Count squares from the centerline to each guard end; both should be 4. Count half-squares from the centerline to each blade edge; both should be 1.5. Count light and mid cells on the blade and confirm light 12 + mid 6 + dark 0 = 18 cells.
Exercise 3
Plot a tapered blade of length 7 squares that narrows from 3 squares at the guard to 1 square at the tip, with the width decreasing by 1 square at counted positions: width 3 for the first 3 squares, width 2 for the next 3 squares, and width 1 for the final square. Use a guard 5 squares wide and 1 square thick, and a grip 2 squares long. The target total length is 10 squares. Check total length and describe shading.
Show answer and check
Blade 7 squares long: width 3 for squares 1–3, width 2 for squares 4–6, and width 1 for square 7. Guard 5 wide by 1 thick centered on the blade centerline. Place the centerline on a half-square line so the 5-square guard extends 2.5 squares to either side and ends on grid lines. For a 3-square blade centered there, the blade edges land on grid lines; mark those as such. Grip 2 long. Total length: 7 + 1 + 2 = 10 squares, matching the target (tip included in blade taper). Shading: upper-left taper edge light, lower-right taper edge mid, lower-right guard dark.
Why: A tapered blade still occupies counted squares; the taper is described by width changes at counted positions. Total length sums blade, guard, and grip when the tip is part of the blade taper, and the sum is compared with the stated target of 10 squares.
Check: Count blade length squares and verify widths are 3, 3, 3, 2, 2, 2, 1 across the 7 squares. Count guard squares from the half-square centerline: 2.5 left and 2.5 right, confirming symmetry and grid-line ends. Add blade 7 + guard 1 + grip 2 and confirm the total is 10 squares, matching the target. Count tone cells and confirm lower-right surfaces are mid or dark.
Exercise 4
A sword drawing has 10 light cells, 5 mid cells, and 3 dark cells. The stated light direction is upper left. Propose one correction if the lower-right guard edge is light, and state the new tone counts after changing 2 cells to dark.
Show answer and check
The lower-right guard edge should be dark under the upper-left light convention, so change 2 light cells on that edge to dark. New counts: light 8, mid 5, dark 5. Total cells remain 18.
Why: The convention assigns lower-right surfaces to mid or dark. Changing 2 cells from light to dark preserves total cell count and corrects the inconsistency.
Check: Re-count light, mid, and dark cells; confirm total equals 18; confirm lower-right guard edge is dark.
Common mistakes
- Shading without a stated light direction, so tones are inconsistent. Mark the upper-left light arrow first and assign each cell one of three tones.
- Plotting edges between grid lines so square counts cannot be checked. Keep silhouette edges on grid lines or clear half-squares and record coordinates.
- Forgetting to count guard and grip squares, so total length does not match. Write total axial length = tip + blade + guard thickness + grip; guard width runs across the blade and is not added to axial length and verify each zone.
- Making the guard asymmetric about the blade centerline. Count squares left and right of the centerline and adjust to match.
Self-check rubric
- Silhouette edges lie on grid lines or clear half-squares and coordinates are recorded.
- Axial length is counted as tip (if separate) + blade + guard thickness + grip; crosswise guard width is not added.
- Guard width is a whole number of squares and symmetric about the blade centerline.
- Tip base equals blade width in squares.
- Shading uses one stated light direction with light, mid, and dark cells counted.
- Style is stated in one sentence and the drawing is consistent with that statement.
- Valid alternatives such as tapered blades or rounded guards are accepted if countability and shading convention hold.

What unit should I use?
Use grid squares as the unit for all lengths and widths, and keep the unit consistent.
How do I check shading?
Count light, mid, and dark cells and confirm lower-right surfaces are mid or dark while upper-left surfaces are light.
