# Twin Tables Optical Illusion

By on October 5, 2007, with 118 Comments

As you may noticed, these two tables appear to have very different dimensions. In fact, the length of the green table is identical to the width of the red table. Also the length of the red table is identical to width of the green table. Quite impossible to believe, right? I attached another image to this post to show you that I was right (like I always am ;). Jump inside this post to see the proof! Very similar illusion can be found inside “relative sizes” category – “Table Tops Illusion“.

Interesting…I would have never believed that without the lines.

The relative size of the tables is no illusion. They are different sizes. Proving they are the same size by showing false true lengths on a perspective drawing is a trick. It’s like saying the moon is the same size as a dime.

I’m sorry… but you’re using 2D lines to measure something 3D. It obviously distorts the distances.

Seen from any other point of view, this tables would have clearly different dimensions. At least that’s what my mind tells me.

interesting, that one really got me! Keep up the good work!!

incorrect. dimensions are close but not exact. measurments should be taken parrallel to an edge.

But if you look at the table legs and how many of the squares on the carpet they cover, they’re different…

This is an wrong one, i think. The blue and yellow lines on the image should be along all the length (width) of the table, not fully vertical (horizontal) to give the actual measure of the table. The only illusion is that it might appear they haven’t the same size in the image, but they are not the same actual size.

I can’t explain it as I’d like to, because I’m spanish and my english is not very fluently :P

Anyway, you’re always on my iGoogle :D

the only problem with your rightness is that you are not completely right. the angles of the table and the lines are diffrent giving the idea that they are the same size. if you go from centerline to centerline on opposing sides the lines would be different.

I jumped in and even measured and they are not equal in any way

12. Julie says:

Interesting illusion…but I don’t know if I’m buying it! The blue line on the green table and the yellow line on the red table look slightly slanted. Shouldn’t they be straight up and down if they really are the exact same size?!?

13. Kristin says:

I had to get out my ruler on this one. I thought, no way he’s right. You’ve proven me wrong again. Great illusion!

14. Peter says:

It’s hard to believe, but then you notice it’s true!

Good Illusion :D

15. Quintin Kerby says:

Interesting. Observe that only the middles are the same. The edges of the tables are not the same due to the perspective. In other words, the blue and yellow lines used for comparison are of a different perspective than the tables. That’s what tricks your eye.

if you have a lcd screen try looking at the picture from near enough above the screen… meaning stand above your screen and look down at the image.. you will notice a big change in the image

THAT MAKES NO SENSE TO ME BECAUSE IF YOU COUNT THE TILES ON THE FLOOR THEY DONT MATCH

Wow, that’s confusing, but really cool!! Great illusion!!

19. Xunto says:

Haha
That’s funny
They are very different, but so sammed…

Am i the only one who sees that the vertical lines are crooked?

21. Anonymous says:

well thats a pretty good illusion.. but it lacks interest..

22. Rishi says:

Its obvious isn’t it?

The reason they dont look the same is because of the thicker parts south of the table tops, these make u think that the vertical part is a higher measurement and the horizontal art is a lower one

Ummm, No. This has got to be the worst “Illusion” ever. It’s Crap. C.R.A.P. Crap. Thanks anyways.

what the heck!?! thx to this site i no longer believe anything i see!

Hm, the wording the length is identical is not correct. The length/width of the tables is certainly not identical, but just their projected lengths as measured by pixels on the screens is. Nevertheless, a nice optical illusion, since its hard to tell you brain to think in pixels rather than in physical extensions, even if you know you should to this in this case ;)

26. David says:

Better yet, measure the four sides of each table, and you will find that the tables themselves are not square. Therefore, no claims that the length of one equal the width of the other can be supported, since neither table has a constant length or width!

27. scheeko™ says:

You’re wrong. You can’t measure it the way you’re doing it. You’re not doing the measurement on the plane of the table tops. You need a “perspective ruler”.

One way to see that is counting the number of (squared) floor tyles. Clearly, for the green table/blue orientation you have 5 tiles between the feet of the table and for the red table/blue orientation you have 3 and 1/2.

Counting for the red table/yellow orientation you see again 3 and 1/2 tiles, meaning it is square. The green one clearly isn’t (5×2 and 1/4 ?)

28. Anonymous says:

Quite impossible??
na, you are simply missing the point of projected images.
I would have believed that ther is any illusion if the visible width of any table is same through out its height, and its not.

That means with your way of measureing width and heights all tables will show this effect. ha ha. Thats not optical illusion but ignorance in measurements:)…

I measured, I couldn’t get it. The yellow lines are closer to the same size than the blue ones (which were about 0.25″ different). But maybe that’s just me!

30. Asif says:

Yeah, these are the real illusions! It’s really amazing to see that seeing is not believing sometimes!

31. Lin (boggart girl) says:

…. These things are so messed up! That’s awsome! I’m always suprised with these illusions.

32. k says:

tesko za vjerovati :)

Unbelievable for my eyes.

That doesn’t take perspective into account. Use just the shapes with no legs and see what we get.

*deleting the widget*

35. Anonymous says:

Hmm I guess… The distracting thing is that the tables are at different angles.

36. otkfgt says:

I don’t think it is an optical illusion – green one appears longer because the pixels are spaced far apart vertically than horizontally?

??

37. Boomi says:

now thats cool

38. Pedro says:

awesome, very nicely done

39. Anonymous says:

This illusion is wrong… As the tables are angled from the point of view, the lines shouldn’t be horizontal/vertical but instead follow the angle of the table. If you draw the lines correctly, they aren’t of the same dimension.

UM… okay…great site, though!

this one sucks. by far the lamest “illusion” yet. (if thats what you can call it) BUSTED

cool first post! yeah i’ve seen this illusion in many forms elsewhere, but yeah it’s pretty cool!

43. mango says:

an interesting, if familiar, concept. I’ve never seen one exactly like this before.

Wow. It’s another goodie!

i saw it straight away tbh…

47. lance says:

they aren’t proportional. they are different sizes by the tiles on the floor and the legs. but the table tops are the same size.

48. Patricia says:

I feel dumb I don’t get it!

The yellow lines match, but the blue lines DON’T match…

woah…

55. Silver says:

Wow!
Put my ruler up to the monitor!! So cool! How come when u rotate the pic, the red 1 doesn’t go rectangular and vice versa with the green one??
CONFUSED!!
:P

56. Anonymous says:

hmmm, green table, looking at the tile on the ground, is 5 squares in length. red table side to side is 3 and a half squares width. red table is 3.5 squares long. with the green being 2.5 wide. am imissing something here?

57. Aroosa says:

WHOA! That’s totally awesome! Hard to believe, but it’s true! I measured it!

58. Junior says:

…..wtf

This one is just too weird. I even measured the sides, and am still not convinced.

thats just insane

…cool

total balls. i measured haha, twisted the image and the red one still comes out more square.

Now THAT is an awesome illusion! I had to measure them myself to be sure! Thanks for putting up illusions that boggle the mind!

geze thats wierd

70. SC says:

this doesnt seem possible but a quick flick of the ruler says ur (as always) right!but why, is it perspective, or just the different colours?

71. Anonymous says:

you are wrong…the dimensions of the two table are not vertical and orizontal (like you think) but are lean according to prospective’s rules…so the two table are different…

that is cool

Cool!
*first comment*
F.W.

not if you measure the length camparing it to the pattern on the floor.. i dont know how to express it better. then they are not even.

its a cool illusion.. but if we used this way to measure stuff then we d have a problem…

76. Meera says:

*first comment dance*
that is seriously cool!!!
i got out a ruler and measured it…=D

77. Chelsey-Ann says:

WOW!Thats really clever,I would never of gest that the two tables are the same width.

Not with my rulers! There is 1/8 inch difference in both!
