PERFECT

I was one inch off on my monitor size. Proportions FTW XDDD

That's the size of an inch? Gee.

omg!! it was exact!!

This is fail

perfect :)

Guys if it's incorrect that because YOU HAVE NO FREAKING CLUE WHAT YOUR MONITOR SIZE IS!

PERFECT on 13 inch

"Yo" is right lol

Awesome, For all you guys who say it's off... Click the button above the image and configure it. For example I held a nickel up to the screen and then dragged the slider until the nickel displayed was as big as it.

1 inch exactly

Perfect!

Hay, #15 ;), thanks for the hint - finally figured it out.

Hmm... Perfect...

Hmmm So accurate

measuring it... A bit too big.

Please show me 9/10, 3/8 other size less than an inch ruler.

Incorrect, I "think." But my fault, I guessed on my monitor size. Time to try again.
Suggestion!: When clicking the "not sure what your monitor size is?" link, give more options to select? Not many people, I'd think, are going to hold a debit/credit card or an American nickel on them at all times.

exactly

My d**k is HUGE

BOO BOO

Amazing. I used my debit card.

It is off the inch is not big enough on 19 in. BTW im not off on my monitor size as the box is right next to me with it on it. 0.0

This is EPIC!!!!!!!!!

I am using a 19" monitor at 16:10 aspect ratio (1440x900); it is correct even when changing resolution while keeping the aspect ratio the same. I have no idea if aspect ratio matters, but also keep in mind to have the page at 100% zoom (I remembered I kept the browser at 90% zoom as default).

I'm hoping it's wrong. Or I'll be disappointing in bed. :(

Brilliant, thank you !

does this website let you look up locations on a ruler? Idk if that makes sense but i just found this website and i really need help... where the heck is .27 inches on a ruler?!?

Mine Is 1.1inch..

Oh how i love the internet x)
