Usually, the hanger size is the same as the joist size, but you can use a hanger that is one dimensional size less than the joist depth—a 2×6 hanger can be used with a 2×8 joist, for instance. Keep in mind that the load capacity of the smaller hanger needs to be adequate to support the load on the joist.
How much weight can a 2×6 joist hanger hold?

| 2×12 | 700 |
What is the most common mistake made when installing joist hangers?
Never use deck screws or drywall screws to install joist hangers. Dont reuse joist hangers. Dont modify them by cutting them shorter. A joist or a truss must lie fully on the bearing.
Is it better to use nails or screws for joist hangers?
The nails penetrate into the wall ledger and therefore offer both better joist load capacity than standard-duty hangers and more protection against uplift forces caused by wind. So, what size screws for decking? The manufacturers agree: Never use galvanized deck screws or drywall screws to install joist hangers.
Do joist hangers add strength?
Joist hangers provide support underneath the timber beam, joist or rafter to provide a strong connection, to resist downward force and to provide structural stability.

How strong is a 2×8?
A 2×8 will support a dead load of 20psf and a live load of 40psf resulting in a total load of 60psf. Depending on the species, grade, and spacing, a 2×8 may span between 7′-1” and 15′-0”. The strength of a board is inversely proportional to the span – the greater the span, the less weight the plank will support.
Is a joist hanger stronger than nailing?
Joist hangers are better because they allow for more accurate placement of joists. They also allow for toe-nailing, plus support the underside of the joist. This makes the hanger stronger than a toe-nail. While joist hangers are an expense, the ease and increased strength make them a better choice.

Can joist hangers be used for floor joists?

What type of screws can I use for joist hangers?

Do you use joist hangers on both ends?

Do you need joist hangers on rim joist?
When a beam supports the joists from below, securing the rim joist to the field joists with through screws will save time over using hangers. Also, in this situation hangers are redundant because the rim joist carries little weight. The main function of the rim joist here is to keep the joists aligned.
Are 2×8 OK for floor joists?
The span for a 2×8 floor joist can range from 7′ 1” to 16′ 6”. In addition, floor and deck joists have to support a fairly high live load because they provide support underneath living areas. You may find that a 2×8 does not offer the necessary support on its own.

|---|---|---|
| Nominal Size (inches) | Joist Spacing Center to Center (inches) | Lumber Grade |
| 2 x 8 | 12 | 15′ – 10″ |
| 16 | 14′ – 5″ | |
| 24 | 12′ – 4″ |
