**glulam beams can span**more than 100 feet.

Likewise, people ask, how far can beams 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.

One may also ask, how do you size a glulam beam? **Glulam Sizing** Typical stock **beam** widths used in residential construction include: 3-1/8, 3-1/2, 5-1/8, 5-1/2, and 6-3/4 inches. For non-residential applications, where long spans, unusually heavy loads, or other circumstances control design, custom members are typically specified.

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

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

How big of a beam do I need to span 20 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.
