That question cannot be answered without knowing the load on the beam.
Length x width. If you are figuring egress, you can only measure the actual opening size.

4 microns is smaller. 600 messh related to openings per square inch. The thickness of screen wire must be reduced from this opening size. For example, 500 mesh screens are rated to have an average 25 microns opening size. For 600 mesh this comes to approximately 21 microns.

The size of a light beam is regulated by the aperture of the lens or the diameter of the opening through which the light passes. A smaller aperture will create a narrower and more focused beam of light, while a larger aperture will create a wider beam.

to help support the building. also to build up the building bigger or taller depending on the size of the beam.
That really depends upon the load you need to carry and the material that the beam is made of.
That always depends on what the beam will be carrying. You will need to consult a building contractor to size any beam correctly. IT ALSO DEPEND ON ITS MATERIAL &ALSO HOW MANY STOREY CONSTRUCTION REQUIRED ON THIS
The weight of a 24-foot iron support beam can vary depending on the specific dimensions and type of iron used. As a rough estimate, a standard iron support beam of this size could weigh around 300-400 pounds. It is best to consult a manufacturer or supplier for more accurate weight information.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
I would involve an engineer on that one. You might end up with an I-beam and pipe support columns, which also need proper support.
Low beam is a 9006 bulb, high beam is a 9005.
It's not a question of opening size but a question of loading over the opening. No load, no lintel. If a 12 inch opening is capped with a 16" block, the block is the lintel. If an opening is between wall studs there is little need for anything that would be called a lintel. Anouther name for a lintel is a header. There is usually some kind of header over an opening. A lintel's size and integrity is determined by the load it will support.
