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.

    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…

  9. Norhild says:

    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!

    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.

    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

    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!

    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.

    But, this seems to be a case of measurements applied without regard to perspective.

  87. william says:

    There’s actually about an 1/8″ difference on the green tables length and the red tables width but that’s still very good becuase the margin looks to be greater than that. The other dimensions are the same.

    RE: TWIN TABLE OPTICAL ILLUSION.

    Hi mate either you have really bad eye vison or you’re a bad illusionist , those 2 tables are NOT the same dimension in lenght and width and i can prove it too. I’d take the images of the screen if i were you, as its its just an in-correct ploy to attract people to whatever it is your advertising

  89. mork sjokolade says:

    I still find this hard to believe. that’s kinda crazy b/c they really look very different. Is it all b/c of perspective or does it have something to do with the background?

    When you see it as a 2d-image, yes. But when you see it as a 3d-image, no. Our brain translates the height (blue line) of the green table to the depth, that’s why whe think it’s longer. When you look at the same blue line on the red table, our brain doesn’t need to translate this into depth, as it is not moving away from us.

    Sorry for my bad English, hope you understand.

    i get how it works! the green table is farther off the ground, so it is bigger because it is closer, and the red table is down farther.

  97. boo says:

    thats hard to believe!

  98. Leandro says:

    The secret here is not to use perspective; the mesurements should be used in the plain image itself. This meas not to use the tiles on the floor to compare the tables.

  99. Naruwan says:

    Yes, the tiles show that the lengths and widths are actually different.

    This is the equivalent of using a yard stick stuck upright in the sand to measure the distance of the ocean from the beach to the horizon. Still cool though!

  100. jkleinrichert says:

    Naruwan (“98th comment)
    —–> great analogy!!!!!!!!!!!

    Vurdlak was merely showing that the lines are the same, in context. Obviously, if you wanted to know the actual 3-d length/width, you’d have to measure parallel to the sides of the table (as mentioned by Norhild 9th comment).

    But this is why it’s an optical illusion people!!! ;-)
    Regardless how you look at it, I still think this is great illusion and it’s a wonderful….dare I say, table conversation piece?

  101. Nick says:

    For this to be correct, you would need a birds eye view of the tables and measure them then. But good illusion.

  105. Anonymous says:

    They are actually NOT the same dimensions. The blue line should not be going at a 90* angle on the page, but from the table’s edge, so it is not the length of the green table but in face falls short of the actual length. So even though the blue lines are the same size on the page, it should in face be longer on the green table, which it is not. The same can be said for the yellow line on the red table.

  106. DJYOCK says:

    OK, break out your ruler……..this is a lie. The width is not the same as the length on either of them….. Don’t believe everything you see or read…. CHECK FOR YOURSELF!!!!

  107. DJYOCK says:

    Ohhh. The same goes on the picture with the yellow and blue lines. The yellow lines are different sizes, as are the blue lines.

  108. moses says:

    RUBBISH!!! if you look at the amount of patterned squares/tles between the width of the red and length of the green you can blatantly see that the green has far more than the red

  109. eries says:

    It right.. But I just cant get my mind around it, it looks so wrong!

  110. lmao says:

    It’s correct. You can’t count by the tiles because the tiles get smaller as they go back. The tiles do not accurately show measurement.

    It IS supposed to be going 90 degrees down because it measures perception and not actual length or width.

    You guys are making stupid arguments that don’t apply with the rules of the illusion. It’s an illusion of optics and not one of actuality. The tables are very well different lengths and widths in reality but because of perception they look the same. That’s what the illusion is saying.

  111. Moshc0re says:

    Wow you all look like fools…. The width is not affected by perspective…… you CANNOT compare width and lentgth by measuring the lines on your screen !!!!!!!! this is why it looks wrong but is “true”

  112. Cormac says:

    Eh, i measure it and um… the lines are not the same length…

  113. Khan says:

    Nice Illusion. The objects in the picture are in an isometric view and the blue and yellow strips (in the 2nd photo) are two dimentional.

  114. yea… not the same lenght… THAT is the illusion!! lol

  115. Jasmine says:

    instead of saying the width and length of the tables, it should have stated the width and length of the rhombus’. it’s the background percepting distance and angle making us think they are different sized tables

  116. Grace says:

    Wow!!!!!!!!!!!!!!!!!!

  117. Matt says:

    They are def, different diminsions this photo is a fraud

  118. Ray says:

    If you have an iPhone or similar phone, hold the phone about foot or so from your face then begin to tilt the screen downward slowly. At one point the shapes will be the same (visually to you). As you keep tilting the screen eventually the red table becomes more like a rectangle and the green table like a square.
