How Far Apart Should Posts Be On A Deck

Hey there, DIY enthusiast! So, you're building a deck, huh? That's awesome! But hold your horses, we need to talk about something super important - post spacing. I know, I know, it's not as exciting as picking out that perfect stain color, but bear with me, it's a big deal.

Why Post Spacing Matters

Imagine your deck as a giant trampoline. If the springs (or in this case, posts) are too close together, it's gonna be a bouncy mess, right? But if they're too far apart, it's gonna sag like a sad, deflated trampoline. Neither is good for your deck, or your back when you're trying to enjoy a nice evening out there.

So, what's the magic number? Well, it depends on the size of your deck and the type of material you're using. But generally, for most residential decks, you're looking at around 16 to 24 inches on center.

What Does "On Center" Mean?

Great question! "On center" means measuring from the center of one post to the center of the next. It's like measuring from one nose to the next in a lineup of noses. You know, if noses could stand still and not wiggle.

Now, let's talk about those 16 to 24 inches. Why such a range, you ask? Well, it's all about the load your deck is gonna bear. If you're planning on hosting wild dance parties out there, you'll want to go with the 16-inch spacing. But if it's more of a quiet, contemplative space, you can go up to 24 inches.

But What About Joists?

You can't forget about those guys! Joists are the unsung heroes of your deck, holding everything together. They should be spaced no more than 12 inches on center. Any wider, and your deck is gonna start looking like a wobbly, uneven game of Operation.

And hey, while we're talking about joists, let's not forget to mention that they should be supported by those posts we've been talking about. A good rule of thumb is to have a post every 6 to 8 feet along the joists. It's like having a personal cheerleading squad for your joists, keeping them strong and supported.

Don't Forget About the Ledger Board

If your deck is attached to your house, you've got a ledger board holding it all together. That board needs to be supported by a post every 6 to 8 feet too. It's like having a strong, steady hand to hold your deck up while you're dancing the night away on it.

So, What Happens If You Get It Wrong?

Well, my friend, you might end up with a deck that looks like it's been through a war. Sagging, uneven, and wobbly. It's not a good look, and it's not good for your safety either. So, let's not let that happen, okay?
