A 2 by 8 beam would be sufficient.
Load carrying capacity of wood beams.
Longitudinal cracks in wood beams of heavy timber structures are commonly seen and can impair the load carrying capacity of such beams.
These tables are provided as a guideline.
There are two different types of loads.
The first step is the same for sawn and engineered wood materials.
Wood screws withdrawal forces allowable withdrawal load force wood species moisture content and weight weight of green and air dried fire wood wood panel and structural timber products mechanical properties density fibre stress compressive strength and modulus of elasticity of clear wood panel and structural timber products.

Aitc beam capacity tables.
A 2 2x10 can span 10 feet and so on.
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.
Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.
In other words it is either going to be on an outside wall or somewhere on the inside.
Dimensional lumber deck beam span chart.
This header must carry x pounds per lineal foot.
The numbers in gray indicate the distance between the support posts.
The formula for the section modulus is beam width times beam depth squared divided by 6.
Two 2 by 4 beams together would not be enough.
Aitc capacity tables provide the uniformly distributed load that a glued laminated timber beam can support based on beam size span and material properties.
This paper presents the experimental and numerical modeling results on 35 pieces of full scale wood beams with saw kerfs that simulate lengthwise checks.
In beam speak you say.
The load on an outside wall with clear span trusses is exactly half the load on each wall.
A two 2 by 6 standard beam has actual dimensions of 1 5 by 5 5 inches which would give a section modulus of 1 5 x 5 5 x 5 5 6 7 6 which is not enough for this example.
