# Which Square is Larger Optical Illusion

By on April 1, 2014, with 12 Comments

I know all of you out there absolutely love it when I post up brain teaser optical illusions, so that’s what I always try to do. Unfortunately, it’s a bit hard to find new ones to post up. If you all have any you’d like to see on the site, you should never be too shy to submit them to me. I will certainly see your submission and most of the time I will include it on the site.

Today, I have an optical illusion that is a brain teaser and also falls into the relative sizes category. I hope you all enjoy this optical illusion and it at least causes you to think a little bit about the correct answer. I want you to leave a comment and tell me: which square is bigger in the image below? The square on the left or the square on the right? Take a look and try to figure this one out.

So, were you able to figure out which square is the bigger one? Let me know in the comments section below. I’d love to see what answers you’re all able to come up with and how you came to your conclusion.

What’s funny is that I’m usually ‘taken in’ like is supposed to happen. That the one on the right looks to be farther back, and thus larger, but in this one, the perspective fails and I can fully see they are exactly the same size. Odd.

Great job! They’re both the same size. :)

Neither, both are 26mm squared. Came to the conclusion first, then measured.

• James Dean says:

Excellent job, Gary. You nailed it.

The squares look the same size to me. But this is probably because, to me, the lines don’t have a 3D (depth) appearance but rather the picture looks flat, like rays of the sun.

Maybe I’ve just been viewing these illusions enough that I can mentally choose how it appears (at least sometimes).

• James Dean says:

You will definitely get better at illusions the more you look at them. And you’re right; the squares are the same size.

Thanks for the kind words. I hope all is well with you, too! Thanks for visiting the site and you’re absolutely correct. The squares are the same size.

5. Mark B says:

The right one looks bigger but I’m guessing they are the same size.

• James Dean says:

Yep, they’re both the same size. :)

6. Munnings says:

They look the same size, am I supposed to think they’re not?

• James Dean says:

Yes, these types of illusions will throw people off, because of the depth of field.
