How to spot the horizon and converging lines? |TIP127


From the previous article, we saw the 5 steps to start drawing a scene in perspective. Let’s spend a bit more time at Step 1: Observation.

Today I give you an exercise to do as often as you want. You will start training your eye identifying the horizon line and converging lines anywhere you g. In the street, a parking, a gallery, try to spot these lines.
Below an example of a common 2-point perspective scene: a regular eye level street view.

Q/ How to spot the horizon line and converging lines ?

How to spot:

  • The Horizon line
  • The Converging lines
  • The Vanishing points

If you are not familiar with these, may I recommend you to watch this video tutorial of
How to draw a cube in perspective. You will get more familiar with the vocabulary.

Guggenheim museum New York City 1I extended the width of the picture. Why ? Because when you take a picture of a city with buildings, it’s pretty common that your vanishing points are outside of the picture.

Note: These kind of common scene suppose that if you look at the buildings on a map, they are all parallel each other.

Did you see that the people in the scene – closed or far – have ALL there eyes on the horizon line !Why ? Because the photographer is standing and holding his camera at this level.

A kid would be lower the line; a giant above.

Let’s find the converging lines.
Spot some obvious lines and converge them toward the horizon line.

They will cross in one dot: the left vanishing point !

Same logic for the right side of the buildings. They converge to the Right vanishing point.

That’s all !
If you know how to observe, you will know how to draw your own cities !


The horizon line is actually
where the Left and right converging lines “merge”.

Challenge of the day

With these 3 pictures below, spot the:

  • Horizon line
  • Converging lines
  • and Vanishing points.

Hint: Look at the most obvious lines such as the windows or the road.

Remember to train your eye wherever you go !
You can play with your friends at spotting these lines Smile. Soon you will do it like a 6th sense !!

If the sketching methods I’ve acquired aid me in my life and in my career, I believe that they can also help you to learn, and help you with your projects. Whether Design is a job or a hobby it doesn’t matter, so long as you do what is important to you.

    Can you post the first image of the challenge of the day with the correct HL and converging lines? I can’t seem to make them all match. I keep getting 2 vanishing points for the lines converging to the right of the screen.

      Hello Chris,

      Thank you for your question.
      You are RIGHT, there is something awkward. And I didn’t noticed it.
      To find out what, let’s both of us play the DETECTIVE ! So try to follow me in that investigation. 😛 (If you take perspective like a game, it’s much more fun)

      I think you noticed that the 3 towers of Park Royal doesn’t match with the perspective lines of the FRONT buildings made of glass.

      At first I made the hypothesis of a lens distortion of my camera. But I checked the map on Google to look at this case closer – And yes, it’s “normal” that all the lines doesn’t match ! There is 2 sets of vanishing points in the scene !

      Now you might wonder WHY?
      To answer you, let’s look at the map together.

      1- I want you to spot Clark Quay (front buildings on the picture) and Park Royal.

      2- If all the building were placed in the map perfectly like in a GRID and the road were perfectly PARALLEL, then ALL the buildings (and streets) would share the SAME vanishing points and converging lines on the picture.

      3- BUT as you can see on the map, the 3 towers of the Park Royal are NOT parallel to the front buildings at Clark Quay.
      The Park Royal follow the [South Bridge rd], while the front buildings are parallel to the [New bridge rd]. These 2 roads are ALMOST parallel, but they are not. That’s why you saw something awkward.

      Conclusion: The scene has more than 1 set of perspective lines. Basically 2 sets.

      TIP: If you were drawing a Urban sketch, you would merge the perspective lines using only 1 set instead of 2 – Why ? Because the difference is not obvious enough to worth the extra complication.

    Hello Chou,
    First, thank you. This is great. Also, are there any tips for find the horizon line, vanishing point and converging lines in products shots, or images with curved objects.

      Hello Majik,

      For curve forms, it helps to imagine the form inside a box. Eg. A computer mouse, or a bicycle helmet… It will help you to draw it from multiple angles.
