business and finance civil engineering industry# How far can a 6x10 beam span?

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.

Similarly one may ask, how far can a 8x12 beam span?

20 to 25 feet is a serious **span** - an 8X8 won't even come close.

Maximum Span (ft - in) | ||
---|---|---|

Nominal Size (inches) | Joist Spacing Center to Center (inches) | Lumber Grade |

2 x 12 | 24 | 13' - 2" |

2 x 14 | 12 | 20' - 10" |

16 | 18' - 0" |

People also ask, how far can a 2x6 beam span without support?

In general terms, joists spaced 16 inches on center **can span** 1.5 times in feet their depth in inches. A **2x8** up to 12 feet; **2x10** to 15 feet and 2x12 to 18 feet.

Re: **20** foot clearspan **beam** size In that case, you **need** something like a 12-16" GLULAM or LVL to **span** the **20**' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists.
