How do you calculate deck load capacity?
To determine the maximum load capacity of your deck, start by calculating its total area and multiply by 50 psf. So, a 100 sqft deck would be designed to support 5000 lbs. Do not get confused with what weight you might think or want to load the deck with.
How much weight can a deck joist hold?
In general, most decks can withstand 100 lbs per square foot.
How much weight can a 12×12 deck hold?
A floating deck designed by code can hold a minimum of 50 lbs per square foot. Calculated as 20% being dead weight, the mass of the deck itself. The other 80% or 40 lbs is the weight you can have on the deck, people, furniture, dogs, etc. A 12’x12′ (144sq’) deck properly supported can hold 5 760lbs on it.
Can a floating deck support a hot tub?
Yes, you can put a hot tub on a deck. Decks built ground level up to 2 feet off the ground can support up to 100 lbs per square foot; sufficient for most hot tubs. But decks 2 feet or higher will need added support. The added support posts should be no more than 30″ apart & ideally placed in poured concrete.
How big should the joists be on a deck?
How do I keep them even? In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2×8 up to 12 feet; 2×10 to 15 feet and 2×12 to 18 feet. The larger the deck, the larger the joists.
How big is a 2×10 floor joist beam?
The joists span approximately 11 ft – one end is supported by a load bearing exterior wall, the other end of the joists rest on a 4×10 beam that spans the width of my garage. Any help is greatly appreciated. Under most US codes your current framing and proposed weight will cause no problem whatever.
How big are the support posts on a deck?

How tall is the carrier beam on a deck?
There is a ledger board attached to the house. The joists run perpendicularly out from the house for 10 feet at 16 inches on center. The carrier beam runs perpendicular to the joists with its center at 8 feet from the house and the cantilever beyond its center point is 2 feet. There are three support posts 3.5 feet from center to center.
As a rule, the larger the deck, the larger the joists. For example, joists spaced 16 inches from the center of the joist next to it can span 1.5 times in feet the depth of their inches. To learn more about deck joist sizing, spacing, and allowable span, reference this chart.

What’s the difference between a 16’and 8’deck?
If you’re allowed to span 16′ with your joists 16″ on center, but you only span 8′ with your joists 12″ on center, then that deck can hold substantially more weight. And, pardon the pun, but boards are only the surface of the issue.
