asked in category: General Last Updated: 16th April, 2020# How far can timber cantilever?

**feet**are allowed to cantilever up to an additional 3

**feet**(see illustration, below).

Likewise, how far can a beam cantilever past a post?

**Beams** are permitted to **cantilever past** the end **posts** up to one-quarter of the **beam** span between **posts**. I like to use this provision when sizing **beams**. Often I **can** reduce the span between **posts** slightly by cantilevering the **beam**.

Similarly, how far can you cantilever a 2x8 joist? **If** the code span tables allow a **2x8** to span 12 feet, then the **cantilever can** be 3 feet.

Beside this, how far can you cantilever a 2x6?

Looking at the table below, we see that **2x6** floor joists **can** be cantilevered up to 2 feet and 6 inches (2'-6") when the joists are spaced 16" apart.

How far can deck boards overhang?

Allow for Sufficient **Overhang** of **Decking** A one to two inch **overhang** beyond the outer fascia **board** is sufficient. This means the installed **deck boards** should have at least 1.75 to 2.75” **overhang** before the fascia is installed.
