I'm using a5paper size with extreport and geometry. Could you please tell me how to add a bleed of 2mm and keep things as they are.

 \usepackage[a5paper,
%hmargin = {3cm, .8in},
left = 2.3cm,
bottom=2.5cm,
includefoot
%right = 1cm,
%width = 10.8cm,
%height = 17cm
]
{geometry}

• "and keep things as they are": So you want to enlarge the paper by 2mm around all edges? – Werner May 17 '14 at 7:12
• Yes... I want just that. I want to keep my layout the same centered with those 2-3mm on each size. The issue is that then I have to cut the paper and there is an error of 2-3 mm – jlanza May 17 '14 at 7:28
• At least in the width, I think there is a key for this “binding correction”, but in the height… I think not. – Manuel May 17 '14 at 8:51

You can set manually a papersize with the added 2mm each side, and then set the option layout=a5paper - that will be what you are working with after. Also you have to set layouthoffset and layoutvoffset to get the content centered on the page.
