Admiral:
How many pixels in MS Paint can you fit onto an A4? (Width x height)
Also, how many pixels in MS Paint is a Magic the Gathering Card?
Bloodbeard:
Depends on the resolution you choose - as everything else on you computer screen.
At 300 dpi (standard printing quality) it would be 2,490 x 3,510 pixels.
I google the answer - I’m smart that way.
Thommy H:
It doesn’t matter - you shouldn’t be using MSPaint for anything.
cornixt:
300dpi is standard for cards, and would be the minimum that commercial printers specify.
MTG cards are 2.5x3.5 inches, so 750x1050 pixels
MS Paint is perfect as a simple PNG editor, very easy to use. Not good for creating content or manipulating jpgs.
Malorndk:
Online Photo editor - Pixlr.com image edit is the way to go if you aren’t savy with graphic programs and doesn’t have photoshop.
JMR:
If it’s a custom MtG card you want to create, there are handy tools for that. I used one to make custom Lore of Hashut cards.
The one I used is called Magic Set Editor, I believe.
Admiral:
@Bloodbeard: Thanks! At googling we got the answer 720 x 1018 pixels, so we’re not smart that way. 
@Thommy H: The best answer, perhaps. 
We were only going to use MS Paint for making a printing page of already finished custom Dwarf cards, but might use better programs if there are any as easy to learn and use as MS Paint.
@cornixt: Thanks a lot for the valuable help!
@Malorndk: Then it’s advice suited for our skill levels. Thanks! 
@JMR: Good tip, I’ll tell my brother about it! It might solve an issue he’s had with a Swedish MTG custom card tool.
Thommy H:
I thought you used Paint.net? Stick with that.
Admiral:
I thought you used Paint.net? Stick with that.I did until a friend smacked me on the fingers for not using Photoshop instead. Since my brother is the one doing 80% of the work on this little project, we're limited to MS Paint, because he don't want any more programs on his already loaded computer. x.x
