I am starting a new deck on my house, I need to know what it the standard distance between the posts to hold up the deck so I can put the footings in the right spot.

The deck is approx. 27' long & 7' High.

It depends on how what size of material you use for the joist and beams.

Check with your local code officals and see if they have a standardized plan.

If not you can use this to get started.

That design will be acceptable in most locations, but you will need to verify it with the local code office. Also some things look footing depth will need to adjusted for you location.

Most books on deck building should show you how to calculate this. The post spacing is dependent on the joist span, which is dependent on the joist spacing, which is dependent on the type and direction of decking and expected load. A good book is **********'s Decks 1-2-3.

BTW, a 27' deck 7' high is a big piece of wood pretty high up in the air. I'd either consider getting somebody to build it or carefully read every deck book you can find.
