How do I make large custom posters?

Question

I'm redecorating and I want to frame some pictures. Is there any way I can make a photo I like and blow it up to be around a poster's size without making it look really blocky or pixely?

Answer 1

if you have a Walgreen's they can do it for cheap i did it with a pic of my horse and put it on my wall.

Answer 2

Poster size is usually 2ft.x3ft.  you will need to have a high resolution photo.  But sometimes you can still pull it off if you touch it up on PHOTOSHOP.  

I'm a graphic designer.  I'm on this when i get bored at work.  

Answer 3
