Drawing something that isn't there anymore feels different than sketching a bowl of fruit or a local park. When you sit down to learn how to draw the twin towers, you aren't just practicing perspective. You're engaging with architectural history. These buildings were the defining feature of the New York City skyline for decades, and because they were essentially giant prisms, they are the perfect subject for mastering 1-point and 2-point perspective.
Getting the "feel" right is the hard part. People often think it's just two rectangles. It's not. If you draw them as simple boxes, they look like cereal cartons. The actual World Trade Center towers had a specific verticality—a pinstripe effect—created by the closely spaced steel columns. They were massive. 1,368 and 1,362 feet tall. If you get the proportions wrong by even a hair, the whole thing looks "off" to anyone who remembers seeing them.
The Foundation of Perspective
Most beginners mess up the horizon line. If you’re looking up at the towers from the street, your horizon line (your eye level) is way down at the bottom of the page. This creates a dramatic "worm's-eye view" where the buildings seem to lean inward as they go up. This is called three-point perspective. Honestly, unless you're an expert, stay away from that for now. It's a headache.
Start with two-point perspective. You’ll need a long ruler. Seriously, don't freehand the main structural lines or you'll regret it. Place two vanishing points on opposite ends of your paper.

The towers weren't actually identical twins in every sense. One had a massive 360-foot antenna. That was the North Tower (1 WTC). If you leave the antenna off, you’re technically drawing the South Tower twice. Or maybe you're drawing the skyline from a specific angle where the antenna is hidden. But usually, that needle is the "tell" for which tower is which.
Proportions and Spacing
Here’s the thing: the towers were square. Each side was 208 feet wide. When you're sketching, you need to ensure that the ratio of the width to the height is roughly 1:6.5. If you make them too fat, they look like apartment blocks. Too skinny, and they look like needles.
- Mark your vertical centerline for the first tower.
- Sketch the "footprint" using your vanishing points.
- Pull the vertical corners up.
- Repeat for the second tower, but remember: the South Tower was slightly offset to the southeast of the North Tower.
If you look at old photos from the Hudson River, the towers overlap. If you look from the East River, there’s a gap between them. Decide your "camera angle" before you put lead to paper.
That Iconic Pinstripe Texture
Minoru Yamasaki, the architect, designed the buildings with narrow windows. This was partly because he had a slight fear of heights and wanted the buildings to feel "enclosed" and secure. For an artist, this means you don't draw individual windows. You draw vertical lines. Thousands of them.
Well, maybe not thousands on a piece of paper, but you get the idea.
Don't draw horizontal lines for the floors. That's a common mistake. The steel "tree" columns ran vertically. To get this right, use a very sharp H or HB pencil. Lightly ghost in the vertical ribs. If you press too hard, the drawing becomes too dark and loses its scale. The "silver" look of the towers came from the aluminum alloy cladding reflecting the sky.

If it's a sunny day in your drawing, one side of the tower will be almost white, and the other will be a deep, flat gray. Because the buildings were matte aluminum, they didn't have sharp "mirror" reflections like the glass skyscrapers of today (think the Burj Khalifa or the Shard). They caught the light softly.
The Details People Forget
The "Tridents." At the base of the towers, those vertical columns branched out into gothic-style arches. They looked like three-pronged forks. This was the "lobby" level. If your drawing is a wide shot of the whole skyline, you won't see these. But if you're doing a mid-range architectural study, the tridents are essential.
Then there’s the skybridge/observation deck. The South Tower had the famous outdoor deck. The North Tower had Windows on the World. These didn't change the silhouette much, but the mechanical floors did. There were "bands" of darker space every few dozen floors where the ventilation and machinery lived. Adding these thin, dark horizontal bands breaks up the monotony of the vertical lines and makes the drawing look "real."
Dealing With the "Shadow" Tower
When you're learning how to draw the twin towers, you have to account for atmospheric perspective. NYC air isn't perfectly clear. Even on a "severe clear" day, objects further away are lighter and bluer.
Since one tower is always slightly behind or further from the viewer than the other, make the "back" tower slightly lighter in tone. Use a 2H pencil for the distant one and a B or 2B for the closer one. This creates 3D depth without you having to do much work. It's a cheap trick, but it works every time.
Common Pitfalls
- The "Leaning Tower" Syndrome: If your vertical lines aren't perfectly 90 degrees to the horizon, the buildings will look like they are falling over. Use a T-square or the edge of your paper as a guide.
- The Antenna: It wasn't just a stick. It was a complex lattice of steel with various platforms. If you're going for realism, look up high-res photos of the 1 WTC mast.
- The Windows: Again, do not draw squares. Draw long, thin vertical rectangles or just shaded lines.
Putting It All Together
Once you've got the basic boxes down and your perspective lines are erased, it’s all about the "finish." Use a blending stump to soften the shadows. The World Trade Center often looked like two giant bars of silver reflecting the sunset. If you're using colored pencils, use a mix of light blue, cool gray, and even a hint of lavender for the shadowed side.
The plaza was also a huge part of the complex. If you have room at the bottom, sketch in the "Sphere" sculpture by Fritz Koenig. It sat between the towers and provided a sense of scale. Without a human-sized object near the base, it's hard for the viewer to realize just how massive these structures were.

To finish your work, focus on the sky. The towers were so tall they often interacted with the clouds. Having a few wispy cirrus clouds pass behind the top of the North Tower's antenna immediately gives the drawing a sense of immense height.
Actionable Next Steps:
- Select your reference photo: Choose an angle—either the "classic" shot from the water or a street-level "look up" view.
- Set your vanishing points: Use the widest paper you have so the vanishing points aren't too close together (which causes distortion).
- Ghost the verticals: Lightly sketch the 1:6.5 ratio boxes before committing to any detail.
- Layer the values: Start with your lightest grays and only use your darkest blacks for the mechanical floors and the deep shadows at the base.
By focusing on the verticality and the specific 1970s aluminum texture, you'll create a tribute that looks like an architectural blueprint rather than a simple sketch.
