The width of the rectangle will depend on how big you want to make your car drawing. Don’t press too hard while you make the main shapes for the car since you’ll need to go back and erase some of these lines.
Pay attention to the overall shape of the car. Some mini or compact cars appear boxier, so make their top rectangles large. Most sports cars look aerodynamic, so draw a narrower rectangle that doesn’t stick out as much. Smaller cars or hatchbacks often have the cabs placed closer to the rear.
Try to make the frame of the car appear smooth from the rear bumper to the top of the cab and down the hood to the front bumper. Keep in mind that some SUVs, trucks, or sports cars might have sharper angles.
For example, a hatchback will have a noticeable curve jutting from the back while a sports car will look sleek and low to the ground.
If you’re drawing a sports car, it may only have 1 slim window so avoid drawing the vertical line in the middle of it.
If you’d like some of the windshield to be visible, sketch a narrow line between the front of the frame and the front outline of the cab. This sliver will look like the windshield.
Imagine about half of a wheel’s diameter and leave that much space for the bumpers.
Some tail lights have several smaller rectangles inside a larger one. You can make yours as complex as you like.
Make your drawing more realistic by drawing a vertical line that shows where the doors are. You should also draw a handle on each door. For example, make your car appear sportier by drawing a sharp zigzag decal across the doors.
Draw your car in pencil regardless of whether you color it or not, since you’ll need to erase some lines as you work. Then, you can go back and color in the car with colored pencils, crayons, or markers if you like.
To draw a trapezoid, sketch a smaller rectangle on top of the large rectangle and erase the 2 short sides. Then, draw the short sides so they slope down at an angle to meet the top of the large rectangle.
The bottom line of the rectangle should run straight through the center of the wheels for your cartoon car. If it helps, draw 4 circles that are touching across the bottom line of the rectangle. Then, erase the middle 2 circles.
If you sketch rounded curves along the edges of the car’s body, use your eraser to clean up the corners.
Don’t draw a rectangle between the 2 wheels since this is where the car doors would be.
You can make the lights any size you like. For a more exaggerated look, make them large so they stick out from the body.
You can leave the window as 1 large window or draw a vertical line through the center of it to create 2 smaller windows.
If you like, go back and fill in your cartoon car with color. Draw with crayons, colored pencils, or markers.
If you want to improve your drawing skills read about art. Do plenty of sketching. Find a good teacher who can help you to observe things better.
