Bearing wall carrying two sections of roof and want to put in a post and beam instead of the wall Wall is 12 ft long What size beam or glulam do you need?

too many variables here, mostly the size of the roof above it (steepness, weight of shingles, tile or slate? etc. You're best to overengineer it. A double thickness (3.5" X 12" or 16" wide) glulam will support a reasonably large roof above it, otherwise a simple double 2x12 would work for a 3/12 -6/12 pitch roof with light grade 30 year shingles.

What is a Laminated Beam?
A laminated beam is a beam that is made of thin layers of a material (Called lamina). An example is glulam beams, which are thin layers of wood glued together to make a large beam.
What is a micro lam beam?
Microlam (or glulam) is an engineered timber product that is made from layers or wood held together with adhesives. The end product is generally made into lengths or beams that are stronger and less prone to warping and twisting than standard timber products.
What size glu-lam will span 20ft?
For a 20ft span, a typical glulam beam size would be around 5-1/8" x 18-1/2" or 6-3/4" x 15-1/2". The actual size needed may vary depending on the specific load requirements and building codes in your area, so it's recommended to consult with a structural engineer or supplier to determine the appropriate size for your project.
Difference between engineering and Non engineering products?
Engineered products are products designed to meet a particular design criteria. Non-engineered products are products that were not specifically engineered for a particular design criteria. The structural wood products industry is a good example of engnieered and non-engineered products. Lumber and heavy timbers are good examples of non-engineered materials that are used in construction. Specifically, lumber or timber is a product that is cut from logs. Lumber is not designed, although we test lumber and have design values that apply to many types of lumber. There exists natural variation in lumber so the way we come up with reasonable design values is test a reasonable size sample of lumber, determine the statistical variation of the test results, then assign a conservative material value to allow it to be used structurally. In contrast, plywood, OSB, I-joists, laminated veneered lumber, parallel strand lumber and glulam are engineered wood products. Those products were designed to be used in certain structural applications. The design of the products was thought out, typically combining a mixture of different smaller layers or materials, combined with structural connectors, typically adhesives, or small nails or screws. These products often use the best properties of the individual products to come up with a better mix. These products often have a higher strength to weight ratio when compared with non-engineered products. Other engineered products include rolled steel shapes, bar-joists, metal decking, reinforced concrete, plastics, composites and fibers. I hope this has been helpful.
