Calculating page setup dimensions for magazine ad

[alxndria]

Hi,

I have to set up a page for a magazine ad, and it has to have these dimensions:

Trim size:  W 9" x H 10.8125"

Bleed: W 9.25" x H 11.0625"

Live area: W 8.375" x H 10.25"

How do I specify this for InDesign?  Thank you in advance!

Use the following in the document setup dialog:

Page size: W 9" x H 10.8125"

Bleed: .125" in all 4 boxes

Margins left & right: .3125

Margins top & bottom: .2813"

Explanation:

Trim size means the actual final size of the document which is the page size.

Bleed is additional area outside of the final size that will be trimmed off.

Live area is the area within the actual size that can be used for text and artwork (other than the background)

That said, the margins look a little funny to me as in my experience, live size is usual even on all sides so all margins are usually the same. However, I suppose that they can be different.
