Establish effective dimension of an image

[Stealth91ita]

Hi everybody this is my first post here

lastly i'm creating graphics for some tshirts that i would to get printed but paint.net for example says that image xyz is 9cm wide when the truth is that if i import it to wordpad with 100% dimension it results 22cm

Now how can i know the real dimensions of an image? thanks

You have paint.net set to inches. (9 inches is about 22 centimeters)

[Stealth91ita]

my paint is set to cm because if i set inches it is 3,8 wide

 

the problem is that the size 100% on screen (9 inch) is far superior than print size according to paint.net

[pdnnoob]

What do you have the dpi set to? (check in the resizing window)

Also, you can't really view images in wordpad. Did you mean microsoft word?

[Stealth91ita]

200 dpi (dots per inch right?)

 

i mean wordpad because i don't have word and it's only to know what is the size on a page

 

with size 100% it is out of A4 page but paint.net says me 3,8inch width

The "truth" here is that Wordpad isn't an image editor, it's a (very humble) word processor.

If paint.net says your image is Z cm in size at a DPI of Y then it is. Simply print it at that density and don't bother importing it into Wordpad.

You might find this tutorial helpful in explaining the difference in print resolution vs screen resolution DPI and YOU

You can try this:

Open your image with Paint from Windows OS  then Select All, Copy  and Paste in your WordPad document.

Or choose Edit>>Paste Special:

sorry i don't achieve to read all "dpi and you"

 

so if i modify dpi to make print size equal to screen size i ruin the image or it's ok?

the image results 20 cm wide (before i said 22 because my plastic ruler isn't accurate xD)

[Stealth91ita]

thanks for the help guys

if i paste it to wordpad it's bigger than 9cm D:

 

i have to be secure than if i send it and other images to printshop the job will be well done..

L.E.

If you insist on using WordPad:

You must Save as (JPEG, PNG, BMP) the PDN image and then open it (JPEG) with Paint from Windows.

Then select all, copy and paste in the WordPad document. Test it with Print Preview.

D:

 

you saved the thumbnail not the real image..

 

it's 771x936

[pdnnoob]

Install this plugin and stop using wordpad

[Stealth91ita]

that plugin is not useful

 

you cannot select any option and the print size now is about 16cm wide, no more 9 and no more 20

 

i'm only more confuse..

1. Stop using Wordpad.

2. Open the Resize dialog. Adjust DPI to the print resolution you want. The image size at that print density is given.

3. Tell your print shop to print at the same print density you used.

You really should read the article DPI and YOU I linked to previously. It explains the difference between screen resolution (PPI or Pixels Per Inch) and print density (DPI or Dots Per Inch). It seems that this is the issue here.

It might help if you post the print requirements of the graphics here.

My guess is the user is having difficulty reading the fantastic article on DPI due to language difficulties. Google translate if very often way off the mark. 

 

EER & PDNNOOB have given you the best advice...

[Stealth91ita]

please only tell me about the image attached on post #9 then i will read everything on my own..

 

click on it not the thumbnail thanks a lot

Your image in post 9 is 771 pixels by 936 pixels.
At 96 pixels per inch (screen quality) that is 8.03 inches by 9.75 inches.(20.40cm by 24.77cm)
At 300 dots per inch (print quality) it is 2.57 inches by 3.12 inches (6.53 cm by 7.92 cm).

Wordpad is a strange choice - perhaps try Open office (free) if you don't want to print from paint.net -
I normally use Word these days.

Do read 'DPI and you' it will help you.
The actual size depends on the resolution - we do not know the resolution Wordpad or your printer are using.
So it is 771 pixels by 936 pixels - the physical size is up to you and your print settings.
