Update: The solution has been posted, you can see the answer by clicking on the original picture!

I can imagine you had enough of all them Ebbinghaus illusions by now, but I promise this the last time! Just wanted to see if all my submissions regarding this topic had any weight, and if the experience you gained helps your brain in processing these kind of tests better. So, which of the surrounding circles labeled 1-8 is the same size as the circle in the middle of the image? Solution will be posted shortly…

To see the answer, click on the picture above!

• John N

5

• m

8 i

• SALLIE

7

• wogabee

Its #2

• zuan

es el # 7…

• I was close.. I picked 4, but in fact, it’s 3.

• Yeah I thought it was 4, it is 3. The diameter of 3 and the middle one is 49px.

• Mark P

I’m gonna go with #4

• Tom

All of them!

• They all the same

• curious

no there not. 1 is the biggest, 8 is the smallest. I think its number 3.

• Kopy

At first I thought this was just like every other illusion where all the surrounding circles would be the same size but then I looked a bit closer. My conclusion is that either circle 3 is the same size as the center circle or neither of them are. But 3 seems to be the closest.

• hishabi

number 5?

• breandan

At a guess…7. 8 looks too small.

• Barbarella

I was going to say all of them but that’s obviously not true. I can’t pick between 3, 4, 5, or 6 and I figure that’s the illusion. There must be more than one. I’ll wait for the solution rather than get out my ruler.

• curious

they are not all the same. i didnt measure with a ruler, but i can tell that they are different sizes, if if it is by one millimeter or so.

• Elliot

3…or 4…no 3. definitely 3

• sharon

excellent but there actually is no difference

• aelveon

[spoiler alert] all of them! I hope

• All of them?

• K4ozz

Number 4!!!

• I’d say, it’s number 5

• Honey

i thought no.5 at first, but it is no.4 ;)))

…probably

• Poppy

I’m going to go for 3.
Because it’s a good number, and
it’s only because I know that it is going to be one of the ones that looks huge, because the illusion is amazing :D

• All of them are the same size.

• Rosina

SPOILERS
I checked all of their sizes in Gimp, and they are all different sizes. Number 1 is the only one that is the same size as the circle in the middle.
Circles 1-8 get progressively smaller.

I guessed number 3. XD

• Rosina

SPOILERS
Ooops! I lied. :( I rechecked and #3 is the correct circle

• asdasd

I think it´s number two

• Synco

When I tried it by just looking at the illusion, my brains would say number 5 is the same size as the circle in the middle.

Since I do not trust my eyes (and brains), because it is an illusion I magnified the picture and took a ruler to measure the diameter. By doing this I found out that cirle 3 has the same size as the circle in the middle.

Crossing my eyes to cheat I think 6 is the same size

• Dave

My eyes want me to answer seven or eight but if I cheat and sort of measure, it looks like number four. Interesting.

• Pygormus

All of them!

• Lizzie

I bet they are all the same size! :O

• Care Bear

Try to imagine how little I care.

• Voigt

You should change your name to “I Care Little Bear”

• Number 2

• kcannarozzi

They are all the same size. It is the size and location of the rings of smaller circles in relation to the center that makes the center circles appear to be of different sizes.

• Rulers Rule

A ruler quickly disproves the “all” theory. Only #3 is exactly the same size – Don’t guess. Know. Otherwise you look either r-e-a-l-l-y lazy or r-e-a-l-l-y dumb…

• kcannarozzi

There is no need to be insulting. My understanding was that we were meant to GUESS and the solution would be provided later. Measuring and optical illusion defeats the purpose and spoils the fun. I am also surprised that you singled me out for my guess when many others guessed the same way. Let’s please try to keep this light-hearted and fun, and not mock others for their posts.

• sinirgi

There not all the same size… I knew that clear ruler I bought would come in handy sooner or later. Still unsure about the correct answer though. 4 maybe

• Bulasty

number 5 isn`t it?

• Michael

Reverse Illusion :)

Taking it into an image editor shows that the circle created by the surround dots are all the same size, but the size of the middle circle changes.

The correct answer is 3. The diameter of the circle is 49×49 pixels, matching the center. (number 4 is 47×47 pixels).

• happy holidays to you mr. v! THE CORRECT ANSWER IS ALL OF THEM IT APPEARS TO ME THAT SOME OF YOUR FANS ON THIS SITE NEED RECONSTRUCTIVE SURGERY OR BI FOCALS THEY ARE ALL THE SAME PLEASE CHECK YOUR OPTOMRIST NEAREST YOU! LOVE NADIA

• vintz72

Nadia, YOU need some medecine I guess.
Mesuring the circles (with either a good Photoshop or a ruler) shows that the #3 is the only one that matches the size of the center one.
However, considering only my eyes, I should have said #7 !

• Beck Ford

Awesome illusion Vurdlak, I really like this one.
Caps are always unnecessary, especially when what you have written, using the caps, is incorrect, especially when what you have written is aggressive and judgmental. I say, logic says, optics says, and brains say: the outer circles are *all* different; number 3, yes: three, is in fact the only circle that has the same circumference as the centre circle.
Ive had my eyes checked, I have perfect 20/20 vision. This isn’t about how good people vision is: this is an *optical illusion* website, please don’t forget that “illusions” are interpreted differently by individuals hence the illusory qualities of these images.

• Amanda

haha. so, either the people who used a magnifying glass, ruler, and multiple picture programs got it right, or you did… i’m thinkin them, stupid. ahhah(:

• josephine

5 or 6? or all because these illusions keep popping up

• Mik

all of them are the same size

• JYANA

6

• Ram

No. 5

• Jessie

They’re all the same size.

• Enlay

Number 3, but i discovered it with photoshop :C …

• TB

I thought 6, but measured and found it was 3. Interesting how many people claim they KNOW the answer when they obviously have not actually checked.

• tito

it’s a good illusion but # 3 is the answer

All, tried measuring with my fingers…

• They’re actually all squares.

• tj

it’s all of them

• Taz

3

• me

3 i cheated and used paint to crop them over

• glp

for once its not an everything is the same size illusion, there actually is a true winner. That winner is #3. I d o financial analysis for a living and couldnt bare to not do some analyzing on this one myself. I can assure you #3 is the same size. Just take some time to copy the circle in the middle, and compare it to the outer circles, max zoom, and #3 is almost a perfect fit.

• Loso

They’re all the same size.

• trisha

8

• Bill

i say #4

• Typeaux

I measured. #3 is the match. I’m with some of the others and thought it was #4 or #5, but those are just a tad too small.

• Cherry Blossom

Tee Hee. I measured it, and i’m pretty sure it’s number 6.

• hs

measure the screen it is 3.

• Aeros

2

• mehreen hasnain

they are all of the same size.its only the placement of smaller circles around the circles 1-8,which is making them look different in size.

• George

They are all the same size… Not that I measured them it’s just that the little dots around the circles shrink in collective diameter making the larger circles look bigger or smaller than they really are… I think.

• Moonchild

Michael is correct, it’s 3. I immediatly thought all of them too but photoshop says 3. 49pixels just like mickael said. Sorry to everyone who thought it was a trick question (inc. me!).

• arch28806

they’re all the same just the little circels are more sped out in each number

• codie

They ARE all the same size. That’s why it’s an optical illusion.

• Someone

All of them!

• Jim Costner

Nice! It took a minute with cut, copy and paste to prove it, but circle #3 is the only one that is the exact same.

• Miky Dallaire

They all are! :-)

• chris

its 3.just measure it with a ruler on your screen

• Marc

3 and 4

• jan

5! lol

• Henk Smit

ALL!

• Ariel

4…….no no, all of them.

• PixelsGarden1

Well, I’m probably way wrong, but I say all of them are the same as the middle, 1-8 inclusive.

• Number 3.

• WilSki97

3!!!

• Selma Cahtarevic

all of them ? XD

• lhai

it’s number 5

• Jakob Lahn Christensen

number 4 i think

• catzrules

all of them are the same as the one in the middle!

• justin

i’m goin with 4

• suzlyn

It’s 3 or 4, I’ll go with 3!

• TumTumTamatem

U think all of them are the same size… or very very close in size.

• shannonihan

3!

• Xheia

This would still be hard without the surrounding circles, I think.

By eye I thought it was 5. Then I measured with my mouse cursor and thought it was 4. Then I see the cut and paste evidence and know it’s 3.

• lb

What the hell is an optomrist?

• Dawn

3

• 3, 4, and 5. Mainly 3.

• TM

3

• TM

Nardia, I wont be going to your eye specialist?

• TM

If its the surrounding circles surrounding the surrounding circles, then it is none?

• Cameron

All same size. Too easy.

• anon.

I think it’s 6.

• Bjarmi

number 2 is right

• kimbo

number 4

• Claire

Awesome, it took me a bit, but paint is my friend. 3 is the same size, though first glance it looks like 8 is.

• Alastair

No 1

• preson

nun

• preson

actually i think 6

• Indigo May Roe

5?

• Sean

I think its 2!

• Sean

But I think 3 is reasonable too!

• Joseph

8

• Markus

I think its the number 1

• Dathomir

All the same…

• Shishir

its 7

• Illusionist

The answer is 3, before posting bullshit (all the same) verify in a image editor, at least you won’t make a fool of yourself :)

• I had to check, but it’s definitely No.3! If you click and hold the image you can drag a ghosted version of it around to make sure! Well, you can on a Mac in Firefox, anyway!

• Joey Tillman

they are not all the same size. not even close. put your mouse inside #1 and then #8.

• Den

how can they all be the same? LOOK AT #8 AND #1! yeah i know the little circles make it look wierd, but if you measure they’re still different sizes!

• try to use MS powerpoint (2007 or higher)

paste the image in the middle of your slide.

then hold Alt and drag the image, an afterimage will appear, it is perfect for measuring. number 3,4 and 5 are the only ones capable of being the same, but 3 really seems to be the perfect clone

• Solution: number 3

• [img]http://i151.photobucket.com/albums/s131/tama2d2/solution.jpg[/img]

• benua

The same : i thought all of them would fit, but in fact Photoshop says only the number 3…

• Kimon

I was gonna say all of them but clearly 1 and 8 are nowhere near the same.

• Suri

The circles get smaller going from 1 to 8 and 3 matches the size of the middle circle

• Ross

Number 1

• Mars

it cant be all of them. I counted the smaller circles that make up the rings, and they are all the same number in each. So the circles inside them get gradually smaller.
I reckon its either none of them – which is just silly – or three.

• Sagamore

On my screen they are all the same size as a dime. so they are all the same size. I mean you know this illusion, so they should all be the same, and in fact are.

• luke

to all the people who said there the same – get ur ruler out. !!! its easy to see there not the same.

• doris

Number 1!

• Beekle

Definitely No 3. How anyone can say they are all the same mystifies me!

• Whoever said # 3 is correct! I measured them too, with a ruler.

• r

i think they are all the same size

• Bulle48

They are NOT all the same size. The tiny circles which go around each # are the same, so the circles in the middle of them are all different decreasing in size as the number increases (#1=largest, #8=smallest)

I think the answer is #1.
The small circles around #1 make it look large in contrast to the center image where the center circle is surrounded by larger circles to make it look smaller.

• Monxy

It is 3. I have checked with GIMP, I am sure. Not all of them are the same sizes. I repeat, it is number 3, I am 100% sure of it.

• Kairho

Well, they cannot be the same size; a quick ruler measurement shows #1 and #8 are quite different.

• Samantha Shireman

Oh my goodness, just measure them folks, they are obviously not all the same. My guess is 3. It’s difficult to measure precisely but with a rough finger measurement you can tell 1 and 8 are different, at least.

• Victoria

Number 4 is definitely the one!

• earthling

It should be fairly obvious that it is not all of them, because one thing that IS constant is the size and spacing of the outer rings of twelve little circles.

• NeeL

Im gonna go for 6.

• uncle sam

• Jeff

Well, measuring with a ruler will reveal that they are not all the same size. It’s a close call between 2 and 3, but I am going to say 2.

• BrainStorm_wf

Cant believe some people says all are the same, when if you see picture 1 & 8 close, is obvious they are different sizes.

I tough at first time that the correct size are 4 or 5, but i’ve checked and is #3.

Good one :D

• jim

You are all so used to saying ALL that you didn’t take the time to measure. Fact is Fact by measure only #4 only.

• jim

OOPS #3

• Carine

6

• Kelly Pennington

i think it is number 8…

• Kelly

#3

• Kairho

Duh … my previous should read “they all cannot…”

• Mark

There are 4 lights!

• steve

all of em

• Cara

Number 3 is exactly the same size as the center circle.

• mikie m

anybody that actually chose a numbered circle over another numbered cicle is a moron

• Bruno Issao

You can clearly see they aren’t all the same size…

• honey

I think its 3

• Pastora

#8

• Karen

only 3 is the same size and the central cirlce

• Ronald

I think they are all the same size

• Snowy

• ebbhyen

I have a Mac. I took the Grab program and selected 1/2 the inner circle. After the picture came up, I lined it up with itself and it was a perfect fit. Then to the outer circles: ONLY #3 was a correct fit.

• No one

7??

• Mars

i did go to the extreme and put this onto paint, and tried them all out. The dimensions are such that three is the best fit, none of them are quite exact, and this is not really an illusion.

• all of them! :)

• Austin

its three. i know its three. the answer will say three. if you didnt say three, youre WRONG. if you did, youre correct. its three, its three,just believe me, its three.

• Neesa

3, i measured them, it’s 12mm in diameter :P

• Noel Kinkela

4 and 6

• Oh wait, yeah I see it. It’s 3. And that Nadia person up yonder istheonethat needs to go seeth optomotrist nearest to her. ANYONE CAN SEE THAT #8 LOOKS NOTHING LIKE #1.

• Sean

Exactly! she is the one who should be seeing a optomatrist nearby her.

• happydoodle

its obviously #3. i figured it out before i even looked at the solution. and for all of you ppl, its NOT #8!!

• Rachel

Sorry the correct answer is definitely not all of them. The center circle definitely matches number 3 and nearly matches 4 but not precisely. I used adobe photoshop to check.

• Anh Pham

good way to check ha ha

• Richard Haviland

I wanted to measure each one, but didn’t. My guess is number 3.

• how come the dude aint posted the answer yet?

• ricky

#10

just kidding
I think all of em are the same.
Note that I said I think

• Joan

I believe they all are the same size

• CheseeCake

They are!

and if you stare at the middle dot then look at wall=magic wall

• A Snail

I suspected they where all the same initially but soon descided that was wrong. Next I went for 4 initially, but on closer inspection 3 is the one. I would have thought changing the size of the big circles would also have made this one harder/more confusing and changing the diameter of the circle of small circles around the numbered circle, or perhaps they where left all the same knowing we would suspect a trick like that :)

• angel

i choose 3

• Isabel

They are all the same size. if they werent, why would this be called an illusion???

• somebody

Itz number 3 cos if u really look 4,5,6,7,8 are too small and 1 and 2 are too big. + i no its one of the big ones cos its a good illusion.

• Voigt

Bye eye only, #5.

• debbie

just ‘cos no one else said it I’ll go for no. 1

• phil

either 3 or 4 (I have bad eyesight) so I’ll go for (flips a coin) no. 3

• tevor

its number 6

• TGG

6

• Sarah-Jane

I think it’s either 3 or 4….
probably 3!!!
:)

• ZL123

At first I thought it was all of them but it in fact is 3 :)

• GAURAV

the circles appear to be reducing in dia from 1 to 8.
can’t decide between 3 or 4 , could be the illusion or that the differences between them are too small .
will wait for respone rather than measure

• pricess

well, i think its circle number eat
but they really look very confusing at first…
but still now i guess.
\

• pricess

im sorry for the wrong spelling
circle number eight rather …

• melpoe

it is one, i measured

• A Smartass Girl

Your measuring isn’t very good. :P

• melpoe

it is one, i measured it.

its no. 3. i measered it with a ruler

• PixelsGarden1

‘Solution will be posted shortly…’

To quote the Moody Blues…”Can I ever get an answer….”

I still think they are all the same…

• agirl

really? its clearly 6

• Matthew Brown

If you think 6, divide it in 2.
:)

I think they all are the same. I just think the lil circles around the circles are moving away from the circle.

• Paul Schilling

Same as ZL123! At first glance they all look pretty equal; however, once any of them either get larger or smaller then #3 is the only precise one! Good one!!

Also Congrats on getting to Yahoo’s! homepage!

• Ashkenazi

1st one I believe…

• vimeospot.com

nice pics on the illusions.

• April

wut am i lukn at?
im lost. wut do i have 2u guess?

To see the answer click on the pic. BTW its #3

• Iris

I honestly don’t see how it can be 3. Even in the solution, 3 is bigger.

• A Smartass Girl

That’s why it’s an illusion.

• 3rd

• Emily

They arent the same size, i measured XP (im not that sad dont worry)

• Oly

They’re all the same size. The trick is that the smaller dots surrounding them gradually move farther away from the dots to make them appear smaller than the center dot. Look again.

• alice

you know, if you have been on this website long, you’d soon realise it’s an illusion- meaning it can’t be six because it looks like it- it’s one or two.

• ALFONSO

THEY ARE ALL THE SAME SIZE, IT’S ALL IN THE DISTANCE OF THE SMALLER BALLS THAT THROW YOU OFF.

• Julie

#4

• Jon

Tis 3 after many minutes of staring. Almost picked 4.

• Jon

Tis 3 after many minutes of staring. Almost picked 4. And they arent the same size.
