How to Draw Flounder — Free Practice Sheets

A flounder is easy to recognize once you know which features matter: a broad, flattened oval body, a rounded head, both eyes sitting on the same visible side, and long fanned fins along the top and bottom. This guide breaks the drawing into four clear stages so you can practise the contour with confidence. The free practice sheets let you trace, copy onto a grid, or complete a partial outline, then compare your work with the full reference.

Start With the Body Shape

Begin with the largest shape, because everything else hangs off it. Draw a wide, flattened oval that tapers gently toward the tail end. Keep the oval low and broad rather than tall; a flounder reads as a flat fish seen from above, not a round fish seen from the side.

Place the rounded head at the left of the oval. The head should blend into the body rather than sit as a separate circle. Lightly mark the tail end so you know where the body narrows before adding fins.

1. Draw a large flattened oval for the body, tapering toward the tail.
2. Add a rounded head at the left, keeping it joined smoothly to the body.
3. Check that the body is wider than it is tall before moving on.

Place Both Eyes on One Side

The eyes are the detail that makes a flounder unmistakable. Both eyes belong on the visible upper side of the head, close together but not touching. Draw them as two small circles with a dot or pupil inside each.

Avoid placing one eye on each side of the head as you would for most fish. That single choice changes the drawing from a flounder into a generic fish. Keep the eyes on the same surface you are showing the viewer.

1. Mark two small circles on the upper side of the head.
2. Space them close together but leave a small gap.
3. Add a pupil inside each eye and check both sit on the same side.

Add the Fanned Fins

Flounders have long, fanned fins running along the top and bottom edges of the body. Draw a dorsal fin along the top and a matching anal fin along the bottom, both following the curve of the oval. Show the fan structure with short lines radiating from the body edge to the fin rim.

Finish with a fan-shaped caudal fin at the rear and a small pectoral fin on the side near the gills. Keep the fin lines light so the body shape stays readable.

1. Attach a long fanned dorsal fin along the top edge.
2. Draw a matching fanned anal fin along the bottom edge.
3. Add a fan-shaped caudal fin at the rear.
4. Draw a small pectoral fin on the side near the gills.

Practise, Compare, and Refine

Use the practice sheets in the order that suits you. Tracing the reference outline helps you feel the contour. Copying onto the blank grid trains proportion and placement. The bounding frame and center guide help you position the silhouette before adding details, and the partial outline lets you complete the missing portion from the full reference.

After each attempt, compare your drawing with the separate full reference sheet. Check the four key features: flat oval body, both eyes on one side, fanned dorsal and anal fins, and a fan-shaped tail. Adjust the proportions rather than chasing a pixel-perfect match.

1. Trace the outline first, then try the contour independently.
2. Use the grid to compare spacing and proportion.
3. Compare your finished drawing with the full reference sheet.
4. Note one feature to improve and redraw it.

Assessing Your Drawing

There are many valid ways to draw a flounder, so judge the visible features and proportions rather than exact line placement. A drawing can differ in fin length or eye spacing and still be correct.

1. Check the body reads as a flat oval.
2. Confirm both eyes sit on one side.
3. Confirm the dorsal, anal, and caudal fins are fanned.

Check your work

• The body is a broad flattened oval that tapers toward the tail.
• The head is rounded and joined smoothly to the body at the left.
• Both eyes sit on the same visible upper side of the head.
• A long fanned dorsal fin runs along the top edge.
• A matching fanned anal fin runs along the bottom edge.
• A fan-shaped caudal fin appears at the rear.
• A small pectoral fin sits on the side near the gills.
• Fin lines are light enough that the body shape stays readable.

Worked example

flounder: Trace the reference outline, then practise the contour independently. Compare with the separate full reference sheet.

Common mistakes

• Placing one eye on each side of the head. Move both eyes onto the same visible upper side of the head, close together.
• Drawing a tall, round body instead of a flat oval. Widen the oval and reduce its height so it tapers toward the tail.
• Leaving the dorsal and anal fins as plain edges. Add short radiating lines from the body edge to the fin rim to show the fan structure.
