@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%!

seems fine on 65'' ON MY TV!!!

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.

Perfectly accurate on my 15.4 inch

thank you

Works good on my 15" I finally got up to get another ruler just to make sure

Seems just right on a 24". ki'e (Thanks!)

loosers

Says my 16" is a 12"

perfect on my 22.

anyone got a ruler for comparison?

(assuming this is correct, instead of blaming the uploader for saying its the wrong size) I think I got my screen size correct now, 15.4 in.

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

looks fine on my 13"

:L that woz funny :) I didn't kno wot 2 expect :) lol

not 100% accurate, but good enough to give me an estimate

Oohh...way off :) 15.5 screen. worked perfectly for CD though

you guys have small monitors haha!!! seriously

big inches. subway's $5 footlong would be more like a $5 3 footlong

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.

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
