This illusion is one of the more common. It’s so common that it’s shown to nearly every intro to psych course that’s ever been taught. It is so so common, in fact, that it is more mind-blowing not to be familiar with it. Anyways, what’s this illusion about? The tables are actually the same size. Sorry to blow your mind.

This illusion is particularly striking, as most of us definitely do not perceive the tables to be the same size. The one on the right, for instance, looks much thicker in width than the one on the left. The left one, in contrast, looks much thinner and more elongated. But, this is only a trick of the eye. If you don’t believe it, take out that ruler and find out for yourself.

My ruler must be broken. Unless the tables are 90° from each other.

Magic. Sometimes I need a long Coffee table, other times a squarish Games table. Turn it around and I've got both. I'm selling it to IKEA.

If it's from IKEA, it will probably depend on just how you put it together.

I don’t understand the term “thicker in width”... which is it, thick or wide?

I’ve sen this before, and you’re right: they are exactly the same.

Thanks for the illusion. Orthogonal perspective makes this possible (No receding lines).

As opposed to vanishing point perspective (RR tracks receding in the distance).

I set a cup of coffee down and it slid off.

In the images flat plane the dimensions are unequal. But correcting for angle of tilt brings the dimensions equal. Figuring the angles is the tough part.
