Object Drawing Lessons
This lesson teaches a repeatable method for drawing a realistic crocodile in side view. You will establish three proportion zones (snout, body, tail), then build scale texture in layers from large plates to fine mesh. The convention is pencil only: scale rows are drawn as overlapping U-shapes with a darker lower edge, and any consistent row spacing is acceptable. All measurements are hypothetical examples; measure your own paper and reference photo before drawing. No habitat scene or other reptiles are covered.

Set the three proportion zones
A crocodile in side view divides into snout, body, and tail. A workable starting ratio is snout 1 part, body 2 parts, tail 2 parts along a horizontal midline, giving a total length of 5 parts. This is a hypothetical example, not a standard. Choose a total length that fits your paper, then divide it into five equal segments.
Mark the midline first, then place the snout tip, the eye ridge, the shoulder, the hip, and the tail tip. The snout should be long and narrow, roughly twice as long as it is deep at the base. The body is deepest just behind the shoulders. The tail tapers gradually and ends in a point.
- Draw a horizontal midline across the page.
- Divide the line into five equal parts and label them snout, body front, body back, tail front, tail back.
- Mark the snout tip at one end and the tail tip at the other.
- Sketch the snout as a long wedge about twice as long as deep.
- Sketch the body as a deeper oval behind the snout, then taper the tail to the tip.
Build the scale texture in layers
Scale texture reads as realistic when it is layered: large dorsal plates first, then medium flank scales, then fine mesh. Use the convention of overlapping U-shapes with a darker lower edge. Row spacing can vary; keep it consistent within each zone. Do not draw every scale at the same size.
On the back, draw two or three rows of larger rectangular plates. On the flanks, draw staggered rows of medium U-shapes. On the belly, use finer, lighter marks. Leave the snout mostly smooth with a few small pits. The tail carries smaller scales that follow the taper.
- Lightly outline the dorsal plate rows along the back.
- Fill the flank with staggered U-shapes, working from shoulder to hip.
- Add finer mesh on the belly and lower jaw.
- Reduce scale size toward the tail tip.
- Darken the lower edge of each U-shape to suggest overlap.
Refine proportion and texture together
Check proportion before adding detail. The snout should not look short or wide; the body should not look circular; the tail should taper smoothly. Compare the three zones against your five-part division. If the snout is too short, extend it rather than shrinking the body.
Texture should follow form. Scales on the back curve with the body contour; scales on the tail follow the taper. Keep the eye ridge and jaw line clear so the texture does not obscure the silhouette.
- Re-measure the five-part division against your drawing.
- Adjust the snout length if it is under one part.
- Check that the tail tapers without bulging.
- Erase texture that crosses the jaw line or eye ridge.
- Add a few darker accent scales near the shoulder and hip.
Worked example
A learner draws a crocodile on a 25 cm horizontal midline using the five-part method. The snout measures 4 cm, the body 10 cm, and the tail 9 cm. Identify the proportion error and state the corrected snout length if the total stays 25 cm.
Worked answer
The snout is 1 cm short. Each part should be 5 cm, so the snout should be 5 cm, the body 10 cm, and the tail 10 cm.
Why: 25 cm divided by five parts equals 5 cm per part. The snout is one part, so 5 cm is correct. The drawn snout at 4 cm is under length by 1 cm. The body at 10 cm is correct for two parts. The tail at 9 cm is also 1 cm short, so extending the snout and tail by 1 cm each restores the total.
Check: Add the corrected zones: 5 + 10 + 10 = 25 cm. Confirm the snout is about twice as long as deep and the tail tapers to a point.
Four practice exercises
Exercise 1
A crocodile is drawn on a 30 cm midline using five equal parts. The snout is 6 cm, the body is 12 cm, and the tail is 10 cm. What is the proportion error and the corrected tail length?
Show answer and check
The tail is 2 cm short; it should be 12 cm.
Why: 30 cm divided by five parts equals 6 cm per part. The snout at 6 cm is correct, the body at 12 cm is correct for two parts, and the tail should be two parts, or 12 cm. The drawn tail at 10 cm is 2 cm short.
Check: Add 6 + 12 + 12 = 30 cm and confirm the tail tapers smoothly to the tip.
Exercise 2
A learner draws a snout 8 cm long and 5 cm deep at the base. Using the guideline that the snout should be about twice as long as deep, is this acceptable? State a corrected depth if the length stays 8 cm.
Show answer and check
No; the depth should be about 4 cm.
Why: Twice the depth of 4 cm equals 8 cm, matching the length guideline. A depth of 5 cm makes the snout too deep for its length.
Check: Divide the length by two: 8 divided by 2 equals 4 cm. Confirm the snout still reads as a long wedge.
Exercise 3
On a 20 cm midline with five equal parts, the snout is 4 cm, the body is 8 cm, and the tail is 8 cm. A learner adds large dorsal plates across the entire flank and belly. Name the texture error and describe the corrected layering.
Show answer and check
Large plates should be limited to the back; the flank needs medium U-shapes and the belly finer mesh.
Why: The proportion is correct because 20 divided by five equals 4 cm per part. The error is texture scale: large plates across the flank and belly flatten the form. Layering large dorsal plates, medium flank U-shapes, and fine belly mesh preserves the body contour.
Check: Check that at least three texture sizes appear and that the jaw line and eye ridge remain clear.
Exercise 4
A drawing uses a 35 cm midline divided into five parts. The snout is 7 cm, the body is 14 cm, and the tail is 14 cm. The learner draws the tail with the same scale size as the shoulder. Describe the texture correction and give one check.
Show answer and check
Reduce scale size toward the tail tip so scales follow the taper; check that tail scales are visibly smaller than shoulder scales.
Why: The proportion is correct: 35 divided by five equals 7 cm per part. Texture should follow form, so the tail carries smaller scales than the shoulder. Keeping shoulder-sized scales on the tail makes the taper look blocky.
Check: Compare the largest tail scale with the largest shoulder scale; the tail scale should be smaller, and the tail outline should still taper to a point.
Common mistakes
- Making the snout too short and wide. Re-divide the midline into five parts and extend the snout to one full part, keeping it about twice as long as deep.
- Drawing all scales the same size. Use large plates on the back, medium U-shapes on the flank, and fine mesh on the belly and tail tip.
- Letting texture hide the silhouette. Keep the jaw line, eye ridge, and tail taper clear; erase texture that crosses these guides.
- Bulging the tail instead of tapering it. Check the tail against the two-part division and narrow it gradually toward the tip.
Self-check rubric
- Snout, body, and tail follow a consistent proportion division, with the snout long and narrow.
- Scale texture is layered: larger dorsal plates, medium flank U-shapes, finer belly and tail mesh.
- The U-shape convention is used consistently, with a darker lower edge to show overlap.
- The silhouette remains clear: jaw line, eye ridge, and tail taper are not obscured.
- Valid alternatives are accepted if proportion and layering are consistent, even if row spacing or scale count differs.
Questions and answers
Do I need a reference photo?
A reference helps, but the five-part proportion method and layered scale convention work from text alone. Measure your own paper first.
Can I use pen instead of pencil?
Yes, if you keep the same U-shape convention and darker lower edge. Pencil allows easier proportion correction.
How many scale rows should I draw?
There is no fixed number. Use two or three dorsal plate rows, staggered flank rows, and finer belly mesh. Consistency matters more than count.
Is this method for alligators too?
No. This lesson is limited to crocodile snout length and proportion. Alligator snouts are broader and are not covered.
