Something Is Wrong With My Brushes

Ok, well I need to do an history project fo skool
and I wanna make the front cover with PS,

Now I made a new document 2480*3508 and 72 pixels,
but now I wanna brush and they are EXTREMLY small when they r on there normal size,
wtf?

 

wrong section this should be in the Computing section

 

oh well,
who cares =)

anyone knows whats wrong??

 

nah sos man. have you tried makin the brush bigger?

 

yea, still not the normal size

 

ok the resolution is set to 72 you said, right? well, its simple then.

a 2480*3508 document is huge, of corse the brushes are gonna be small. the brush size changes accordingly to the size of the opened document

 

buttttt

that 72 is fo the text right?
72 pixels
cuz if it changed to 72.009 its gonna be real weird...

 

okay. zoom into 100% then brush. its gonan tka eu an hour to brrush te ---- but there it is. ur apparently looking at the brush size on a zoomed out canvas wich makes the brush smaller.
im prolly wrong shoot me.
