How to Draw a Computer: Step-by-Step Guide

Drawing a computer can seem tricky with all its parts, but this guide breaks it down into simple shapes and lines. You’ll learn to sketch a realistic desktop computer setup, including the monitor, CPU tower, keyboard, and mouse. No prior drawing experience is needed—just follow along with basic geometric shapes.

What You’ll Need

• Paper (plain or sketch paper)
• Pencil (HB or 2B for sketching)
• Eraser
• Ruler (optional, for straight lines)
• Black pen or marker (for outlining, optional)
• Colored pencils or markers (optional, for shading)

Step-by-Step

1. Draw the monitor frame: Start by drawing a rectangle in the center of your paper. This will be the outer edge of the monitor. Make it slightly wider than it is tall—about 2:3 ratio. For a typical monitor, a 4-inch by 6-inch rectangle works well.
2. Add the screen: Inside the rectangle, draw a smaller rectangle, leaving a border of about 0.5 inches on all sides. This inner rectangle is the screen. If you want a curved monitor, you can curve the top and bottom edges slightly inward.
3. Draw the monitor stand: From the bottom center of the monitor frame, draw a short vertical line downward (about 1 inch). Then draw a horizontal line at the bottom of that line to form a base—like a flattened “T”. The base should be slightly wider than the monitor’s width.
4. Sketch the CPU tower: On the right side of the monitor, draw a tall vertical rectangle. It should be about half the width of the monitor and about 1.5 times the height of the monitor. This is the computer case. Add a small circle near the top for the power button, and a couple of small rectangles below it for USB ports or a DVD drive.
5. Add the keyboard: In front of the monitor, draw a long, thin rectangle that is slightly wider than the monitor. This is the keyboard base. To give it depth, draw a second rectangle just below it, slightly offset to the right, and connect the corners—this creates a 3D effect. Add small squares or lines inside the top rectangle to represent keys.
6. Draw the mouse: Next to the keyboard (usually on the right), draw a small oval or rounded rectangle. Add a line down the middle to separate the left and right buttons, and a small circle at the top for the scroll wheel.
7. Connect the parts: Draw a thin line from the back of the monitor down to the CPU tower to represent the display cable. Draw another line from the keyboard to the CPU tower, and one from the mouse to the CPU tower—these are the USB cables. You can make them curved to look more natural.
8. Add details: On the screen, sketch a simple desktop background—maybe a few icons (small squares) and a taskbar at the bottom. On the CPU tower, add a few small lines for ventilation grills or a glowing LED strip. On the keyboard, you can add a spacebar (a wider rectangle in the middle) and a few extra keys.
9. Refine and outline: Once you’re happy with the sketch, use an eraser to remove any extra lines. Then, use a black pen or marker to trace over the final lines. Let the ink dry, then erase any remaining pencil marks.
10. Shade and color (optional): Use colored pencils or markers to add depth. Shade the sides of the monitor and CPU tower to make them look 3D. Add a subtle gradient to the screen (e.g., light blue for a sky background). You can also add a shadow under the keyboard and mouse.

Common Mistakes

• Proportions off: Making the monitor too small or the keyboard too large. Use a ruler to measure relative sizes, or compare with a real computer.
• Flat perspective: Drawing all parts straight-on without any depth. Try to add a slight 3D effect by offsetting edges and adding shading.
• Forgetting cables: A computer without cables looks incomplete. Even simple lines connecting parts make it look realistic.
• Overcomplicating the keyboard: Trying to draw every single key. Keep it simple—just a few rows of small squares is enough.
• Messy erasing: Leaving smudges or not erasing guide lines. Use a clean eraser and work carefully.

Tips

• Start with light pencil strokes so you can easily erase and adjust.
• Use a ruler for straight lines, especially for the monitor and keyboard.
• Look at a real computer or a photo for reference—it helps with proportions and details.
• Practice drawing the monitor alone first, then add the other parts.
• If you want a modern look, make the monitor thin and the keyboard flat.
• Add a desk line or background to give context to your drawing.

Troubleshooting

• My monitor looks like a rectangle with no depth: Add a slight curve to the edges or draw a second rectangle behind the first, offset slightly, and connect the corners. Shade the side to create a 3D effect.
• The keyboard looks like a plain box: Make sure you draw the keys—just a grid of small rectangles. Also, add a slight perspective by making the top edge slightly shorter than the bottom edge.
• The CPU tower is too wide or too narrow: Compare its width to the monitor. It should be about half the monitor’s width. Adjust by erasing and redrawing.
• My lines are shaky: Use a ruler for long straight lines, and try drawing in short strokes. You can also use a lighter hand to keep lines smooth.
• The cables look like they’re floating: Make sure they start from the back of the monitor and go to the CPU tower. Add small connectors (like a trapezoid) at the ends.
• I can’t get the screen to look like a screen: Add a slight glow or reflection—a diagonal white line across the screen can simulate a glare. Also, draw a taskbar and a few icons to make it obvious.

Frequently Asked Questions

Do I need to draw every key on the keyboard?

No. For a clean look, draw a few rows of small squares or rectangles. You can add a spacebar and a few function keys, but don’t worry about accuracy—it’s a sketch.

How do I make my drawing look 3D?

Use shading. Pick a light source (e.g., top-left) and shade the right and bottom edges of each part. Also, draw the sides of the monitor and CPU tower by adding a thin rectangle on the side.

Can I draw a laptop instead of a desktop?

Yes. Draw a thin rectangle for the base, a vertical rectangle for the screen, and add a keyboard on the base. The steps are similar but simpler—no separate CPU tower.

What if I want to draw a computer from a different angle?

Start with basic shapes and use perspective. For a side view, draw the monitor as a thin rectangle, the CPU tower as a box, and the keyboard as a flat shape. Practice with simple shapes first.

How long does it take to learn to draw a computer well?

It depends on practice. With this guide, you can get a decent result in 15-20 minutes. To improve, practice drawing different computer models and styles regularly.

Can I use this guide for digital drawing?

Absolutely. The same steps apply. Use layers in your drawing software—one for sketch, one for lines, and one for color. Use a tablet pen for precision.
