@Ineed to save Money

Our computers are probably better than yours.

Also, it is slightly too long.

Fix'd. I did 13.4 and not 13.3!

We are anonymous, we are legion. We do not forgive, we do not forget.

just perfect, and a really useful thing (IE 15") I use it to measure knitting gauge when I am on the go.

make sure your computer isn't set to save it at more than 100%!

perfect on my 22"

Perfect fit.

looks good on my 24" (Ubuntu/FF 3.5)

I need the ruler to measure my monitor... ???

Bit small... I think my browser (Google Chrome) resizes image to be at their native resolution.

this crazy

this sucksss

my pesis is ten in ..looks so small next to my 65in mistubishi tv

the size is perfect, i measured it.

Too big on my 15".
Using google chrome though...

to the people who say the size is wrong:

set the ACTUAL size of the monitor (diagonal in inches), even decimals matter. i measured the diagonal of my notebook display with a ruler and it's 14.95 inches, so i set exactly that.

in case you're european: 1 inch is 254mm or 2.54cm

i measured the 10 inches of the ruler shown on the monitor (my monitor is too small to show all the 12 inches horizontally) with a ruler and it said 25.4cm so the size of the thing is perfect.

bye
PS: somebody tell me: GET A LIFE!

I am curious
about the size of my Hp pavillion Netbook,but Im
pretty sure its 12 inches.Just incase i am mistaken,
i checked the size on this:http://pective.com/pic/1-foot-ruler website.But Now I am Still uncertain about the direct increase of its length and width.I havent a ruler nor tape measure in sight,just my laptop and I in this hotel room I have rented for the weekend while staying in san diego for the college international scholastic decatholon.

Now to cross-check with my DS to confim the results..

perfect size on 15.5

Perfect on a 42" 1080x1920. I think screen aspect ration could make a difference. I measured the length of my iphone to check, it was right on: 4.5 inches.

Perfect on my 19"

what's the true and actual size of 12" ruler?

looks great on 420in projector

You guys need to set your dpi to get a proper display size
http://members.ping.de/~sven/dpi.html
after adjusting, you can hold a peice of computer paper up to microsoft word and it'll be the same size

seriously, how hard is it to get a 12" ruler right?

not the right size AT ALL

this is waaaaaayyyyy too big!
we used this for my little sister's homework, and it was all wrong!
thankfully, we found a ruler before she handed it in the next day.

this works great! if you enter your MONITOR size!
this can be measured by looking it up,or measuring your screen diagonally.

not even close on my 56"

perfect on 13.3 in. Just look for your comp model num on the web and get the monitor's exact dimensions...

way off on my 55"

Perfect on 15.6

this is

I dont like this at all it doesnt work by any means i evev measured my computer ( not really ) and it didnt work

21 is perfect

not too big no too little hd 21

You are retarded if you are measuring your computer screen from side to side. You measure it diagonally.

Perfect for 19"

off by .1inch for 19"

Ruler works perfectly on all resolutions, tried several different ratios and they all are exact.

I think many of the negative comments here are from people who either don't know their screen size and think they do, or don't realize you measure diagonally.

Once again, the bell curve 'rings' true. Ha! Ha!

No one will get that joke either.

Thank you, very handy

Boom Boom

great on my 27" beat u's all lol

good on ma 52" LED beat that "nobby"

this sucks

works perfectly

How are we supposed to measure the moniter, we wouldnt be here if we had a ruler!!

Too short

I have a 22 but it was small so i put it on 20 inch, compare with 11" printer paper to get the right alignment (The smaller the screen the bigger the ruler) :)

good

Worked great on my 16" monitor. I didn't have a ruler to measure my screen size so just looked up my computer model online..

Perfect on mine.. maybe not entering the correct monitor size so it can calibrate correctly.

wheres the 24" wide screen aspects?

**measured my d**k against the screen.. if this scale were smaller, then my d**k would be longer by 2 inches in real life.. haha

Doesn't work

Hahahahhah^^

Looks awesome on my cinema screen

How is a cat related to a ruler?

Perfect fit on 15.5".

If this was right my d**k would be just 6 inches long. These are giant inches.

Disaster on a 24 inches Acer LED monitor.

I DONT KNOW MY SCREEN SIZE THATS WHY I NEED A RULER!!!!!!!!

perfect for me. my screen was 10.2

Perfect on my iPad :D

not so good. great idea though

If anyone was f*****g smart they would scroll down a bit and look at the left side of their screen and look at the tags. Over there you can choose the size of your monitor. Stupid.

loooks good on 25 inch hp2509m

Perfect for me on 24".

accurate on my 23" IPS LED Monitor, I think everyone else better make sure of their monitor sizes, someone might have gotten screwed.

you people are all wrong u are just measuring ur computer wrong i have an 11incher and it works perfectly

on point. i have a mini laptop and ITS VERY ACCURATE

on point. i have a mini laptop and ITS VERY ACCURATE

21.5 Inch Screen perfect

fits onto my 10" screen....

Bang on!

>^,,^< ~PurrFect.. 17"

14" perfecto.

I hope people realise that all screens are measured diagonally, corner to corner and the ruler is displayed horizontally.

Used my debit card because i didn't know the exact size of my schools monitor and it works perfectly. Helped a lot in measuring. Thanks ^^

Worked great on hp mini, using a credit card.....wow my screen is small though, only got 8.75" of the ruler, but it was way useful.....COOL

21.5 inch mac perfect

I tried doing this on an iPad, then I realized I was zooming in and out. XD

great on 13 in. measured exactly to my ruler

I found selecting that I didn't know my monitor size, and then using a dollar bill as comparison, worked excellent. I suggest trying this to get it just right.

U MAD

Way, WAY too big on my 27". why doesn't this just ask for your screen resolution instead? that'd be easy.

they have that nifty tool where you can put an object(credit card, coin, dollar bill) on the screen and make the image of that object the same size as the object to figure out your screen size. I didnt know my screen size and couldnt measure it(duh, I googled for this so no ruler) and after sizing the image to my item the ruler worked perfectly. I came back to double check once I found my measuring tape. Its accurate if you adjust it properly.

It's dead on for me.

why would u ask if its correct? i search for this coz i dont have ruler with me damb a*s, how would i know

perfect size on my 24 inch

i dot know

Going by the fact that my p***s is 9.5 inches hard.... i'd say this is about right.

very accurate on my 18.5" screen.

wow

well this really did help and it was perfect on my 15.6 screen.... i needed it to measure an ide drive cable

this website is ok but its a little crapy

Monitor 19" - used ruler to check it, right on. Perfect

12 used ruler and about two inches off.......

For everyone whose screen is off, it depends on resolution so just say that iyou don't know the screen size and measure according to objects

If you are touching the screen with your p***s right now, take it off you are gross.

Wow, this website is poo im quiting on it.

perfect on my 17 too

95% accurancy on my 20" lcd

yeah dis s**t be perfect on 17 inches n***a

Close but i'm not sure cuz i dont have a real ruler with me1 ;3

Works to excellence on the 20 inch screen

The way to go is the size comparison route. You units display size may vary.

this makes no sense to me

>^. ^<

My screen is a 17.5 inch and this ruler looks perfect to me. I haven't measured it against an actual ruler, but it looks right.

And also, depending on your connection it might look huge. It always pops up about 3 or 4 times larger when I first open the page, but then it shrinks down to size after a few seconds.

ever so lightly too long on my 9.85 in

Mine was perfect on 18.5 inch

perfect at 19

BTW if u like turtles eat a banana right now. cuz I'm from canada

perfect at 17 inch, very useful :)

good for me!

According to this ive got a 5 inch c**k. And its Right. PS im 14.

Perfect on my AOC 22"

work fine with "21" monitor

Perfect for 22"

Hey random dude I really want a d**k in my a*s.

I did not assum the size of my monitor not blindly follow the size that is indicated by the manufacture of my monito and employed the calibration tool attaced to this program. Doing so, and then checking with a yard stick the image shown is accurrate.

it's too small for 15" by 3/4"

Much too large on 19"

To everyone who says this is wrong, it isn't. Most of you probably used the manufacturer size, which is actually an estimate. 15" is usually 15.4", etc. 15.4" works for mine.

fairly accurate on 14.1"

works great on 23". spot on.

All the people saying that it's much too large and stuff, I don't think you realise that you have to change your monitor size on here for it to adapt. Mugs

depends on ur moiter size weather its acurate or not i guess :P

I dislike Biology :(

100% Correct on 20 inch

Fine for chrome on 10" netbook.

My p***s grew! :D

cool tool!! Got a chance to use my Euro coin, for yet another interesting purpose. :)

11 and a half inches exactly on my 23 inch monitor, yet when i drag it onto my (don't mean to brag) second monitor (15 inches) it's also 11 and a half inches.

How the h**l am I supposed to know the size of my screen without a ruler?

This was perfect ruler
*kills ork*
*get's shot by tryanid*
*kills tyranid*
*dies*

Exactly 1/16" OVER actual size.

on my for inch kindle its a peice o s**t not even close

According to the ruler I used(a small 6 inch) it's perfect on a 24inch monitor.

Works perfect on Dell 15"

ooops, that's a 15.6" screen on my Dell Inspiron 1545, it works perfectly! Thanks for this provision, I'm handicapped and use it often.

actually mine is right on point :) good website.

It works if you know how to use it. I really isn't that hard.

@Jaezilla. What size did they sell you, you nugget.

Spot on, Dell ST2220L (21.5")

seems perfect on a 13inch mac

Usually things just don't seem to work for me but this one did. It's freakin' AWESOME! Also, exactly what I needed to know what size travel/cosmetics bag I needed to purchase online. I'm sharing this link...

Ewwww

Exact measurement!! Awesome!

I hooked up an old 8 inch, changed the resolution... Didnt fit right

Pretty close, just like a cm away on my 17.5

Not even close >:(

nothing but C***!!

perfect

Perfect on 15.6"

I found it to be within a 1/16 of an inch but you have to put in the exact dimension in my case 18.1

exact

INCORRECT! It said that my moniter is 15.7, but it is really 13.5 exactly.

Why can't I change the screen size? Now I'm stuck with the wrong size. Stupid.

this doesent work on 10.1 inches 1980 by 800

perfect, thank you!

perfect on 15.6
Thanks

Perfect Size :) for a 21"

WHAT?? it's a 21 in. soo the 19 in. thing it just said is wrongg

I used their generator & a debit card to adjust the size. Works perfectly. Not sure why people are having a hard time, perhaps you should try it a different way?

Used a CD to adjust the size and then measured it against a measuring tape. Pretty perfect actually.

Perfect on my 16, I used a sheet of paper (8.5 by 11in.) to estimate and to check, worked perfectly.

It shouldn't surprise me, but there are a lot of idiots here. If you set up your monitor size correctly, it works. I used a US nickel to set the size and US penny to check correctness (a US penny is 1/16" thick, a stack of 16 pennies is 1" tall, and a row of 16 edge to edge is 1 foot long).

Is the monitor size they give across or diagonal? I ask because a different site said my monitor was .4 inches more than pective did.

too big on 15 inches

Just because it gives a small size for your d**k doesn't make it a wrong estimate; I hate to break that to everyone.

your measurement with a disc was right on the money! thank you.

this is frigging shiitt

Heap of s**t

Really close, if not exact on my 23". Nice!

THIS DOESN'T WORK CUZ I AM HOOKING THIS UP TO A 63 INCH TV

Me no gusta!!!!!!!!!!!
this no frikkin work

If I use this thing to measure my body, my third leg is a flagpole. The inch show is about 2 inches in real life.

d**n my d*ck is too big to measure on my 27 inch screen:/ ohh well looks like ill be using the meter stick.

Wht the F**k does my 27' screen look like a freaking 12'??

hiiii

perfect on 14"

It's a perfect 12" on mine......when i fold it in half!!!!!!!

Hello thar.

Perfect on a 17'' screen! I accidentally clicked "incorrect" though. :(

This isn't close

It stays on the same size for me

WAYYYY TO SHORT ON 8 INCH.

great! cool and accurate! it helped me with my homework! :D

@ Bradley
you have a 6" monitor. :D

thanks to this my math homework is finally finished!!!!!!!! YAY!!!!! :D
{(|)}

Seriously most of the people who said it didn't work entered the wrong monitor size!

Some people probably aren't realizing your SCREEN SIZE IS MEASURED DIAGONALLY..... NOT HORIZONTALLY it works fine for me on my 15in mac, so if you got a pc and your having problems that could be the reason too

Hey people after inputing your monitor size get an actual ruler and "Calibrate" your size to screen, so measure the ruler on your screen with a known hand ruler? Messure the applet size and either increase or decrease the monitor size changer until the measure onscreen measures as close to real as possible then remember the moitor selection in order to fit your on screen experience, this way you can bookmark the site with that setting and have at least a portable ruler on screen pretty close the most accurate you can adjust. It still is useful and is intuitive.

Far too big on my dual monitor display

<html>
<body>
I don't know my monitor size
</body>
</html>

good concept but not right measurement

for those saying its not the right size try right clicking on the image and click view image and see. (dont zoom in)

beautiful, just adjust it til it fits...

They should ask for your screen resolution rather than screen size!! This will fix their 'too big'-'too little' issues..

thx

how am i supposed to know if it works when i dont have a ruler to measure the size of my monitor!

Insanely short on my 27 D:

Close enough.

6 inch circle? Perfect. 12 inch ruler? 2/16th of an inch off.

Perfect once I got the screen size correct - 16.28 screen

This makes my credit card 6 inches long, I don't think so...

my email lancefernando@hotmail.co.uk

im high

once i done a size it will not let me pick again???????????/

did fine to me!

If I had a ruler to check the accuracy, I wouldn't have been searching for this online ruler!! :-) I think it looks reasonable on my 15 in macBook Pro monitor...

you all should just use a piece of computer paper.. 8.5 inches by 11 inches...

On my 17!

Dang!! Impressive this is perfect size

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).

Shouldn't this app also ask for aspect ratio?

Worked good on a 27" 16:9 screen, but I can't imagine how this would work on a 16:10, 5:4 or 4:3 screen...

I guess that's why so many ppl report wrong length...

19" monitors get reasonably good rulers on the screen, so change your screen to 19" and it might work(:

17" works perfectly

15.6" perfect checked with standard A4 paper be sure to give it your diagonal length

Perfect on 15.5

dgdgdf

I'm confused.......

What the heck is a monitor?!?

this thing confusing!!!! :P

This helped greatly with my project. Works GREAT on 16.2

perfect on a 15 inch

Who here is measuring the size of their d**k

I out my d**k next to it and it seemed a bit off

Helped with my project, ruler was great! same size as my d**k so i believe it is correct!

Perfect

acurate but require option to make vertical ruler

IF I HAD RULER TO MESSURE MY SCREEN SIZE OR CALIBRATE AS ONE PERSON SAID THEN WHY IN THE H**L WOULD I NEED THIS RULER!!!!! AND WHAT THE H**L IS A COMPACT DISK?

if this is right my d**k is 12in long

;love a ruler

wow

wow

works perfect, just use the screen calculator thing. I did it with a u.s. bill.

This worked perfectly, you just need to adjust it correctly

My screen is 15.4", but 17" seems to be more accurate. On a side note, I can make my p3n!s seem bigger or smaller with this! :D
