Tear down load-bearing wall

Renovating and considering tearing down a load-bearing wall.
The question is what dimension I will need for the glulam beam.
I will have 2 columns for the beam, what dimensions do they need?

Length 3200 mm
Snow load zone 2.5
Center distance of roof beams is 700 mm

//Glulam beam

A section is needed where the rafters' dimensions are stated if one is to calculate it. The use of the upper floor and the design of the outer roof are also important.

A section is needed where the dimensions of the roof truss are indicated if one is to be able to calculate it. The use of the upper floor and the design of the outer roof are also important.

Yes, that page was good.

What do you mean by the dimensions of the roof truss? Thickness?
Upper floor regular room

Roof slope and the placement of support legs, as shown in a sectional drawing.
