What size should ledger board be?

Last Updated: 18th February, 2020

As a general rule, you should use the same size of board for the ledger as you plan to use for the joists. You can use a larger board, however, if it allows for a better connection to the house framing. Calculate the length as 3 inches less than the width of the deck framing.

Besides, can I use 2x6 for ledger board?

2x6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Joist hangers are used to attach the ends of joists to the face of a beam or a ledger board. If you identify a crown in the board, you should always install it upwards.

Likewise, how far can a 2x10 span without support? When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.

Keeping this in view, can a ledger board be two pieces?

You are required to have a minimum of two of those assemblies on your ledger, and your inspector could well consider a two-piece ledger as actually being two ledgers.

Does deck ledger need to be one piece?

If possible, you will want to have the ledger be one long piece of stock. However, if the length is over 16' - 18', it may be hard to find a straight piece that long. In this case, two pieces will work. Always try to use pieces that are at least 6' - 8' long.

How many lag bolts do you put in a ledger board?

Traditionally, lag screws have been the most common method of attaching decks to buildings. To properly attach a deck ledger using 1/2" lag screws, 5/16" holes need to be pre-drilled through the ledger and rim joist. After that, a 1/2" hole should be drilled through the ledger only.

According to the International Residential Code², adopted by most states, a deck does not need a building permit if it is “less than 200 square feet, under 30” off the ground, does not serve a required exit door, and is not attached to the dwelling“ — if it is freestanding.

How much weight can a 2x8 support?

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2x8 @ 16" oc and most preferbaly 2x10.

How far can I span a double 2x8?

No, you cannot span 23 feet with conventional lumber, even doubled. It'll be as bouncy as a trampoline and won't meet code, and that's if you can find such lengths. You'll need at least a 12" (nominal) I-joist or an engineered floor truss to span that far, or you'll need an LVL or steel beam midway.
