I am in the process of renovating and will create a new living room from two existing bedrooms. The wall between the bedrooms is not load-bearing, so I can take it down without major issues. However, the new intended opening to the living room will be in a load-bearing wall.
The opening is intended to be somewhere between 1500 and 2000 mm. Probably closer to the former.
What dimension should I have for the beam to support this? Is there any smart service that can help me calculate this?
Thanks in advance

And snow zone affects.
Building notification to the municipality is required and it must be approved before work begins.

Of course, that's true, otherwise, it's a bit like asking "how heavy is a stone?"A AG A said:
I was just wondering if there's a "calculator" for these types of questions. Where you can input all the data and get help with the dimensions.But anyway:
The house has a basement + 1 floor. Above, there's an attic and a roof consisting of roof tiles. It's a wooden frame. Snow zone 3.0 if I've checked correctly (Sundsvall). I can send some drawings if that helps.

If it's only about a 1.5-2 meter opening, you probably just need to put together a couple of 45x145 wooden beams and use them as a beam. Unless it's an unusual type of house or there's load in the attic. A drawing would probably help.Sandersson89 said:

There are calculation programs, but it takes some knowledge to input the correct data and interpret the results.
The suppliers of glulam beams have calculation programs, the problem is, as mentioned, that you don't know what numbers to input or if the model is relevant for your specific house.
A glulam beam 30-40cm high is probably appropriately over-dimensioned for your 2m, don't forget to build proper posts that rest on something that doesn't move.

I used that calculation help as the first input when I was working on some plans at home. I then had the now deceased forum member justusandersson (RIP) also calculate it, and the suggestions were very similar.

What kind of roof trusses are they?
If they are truss roof trusses and the house has a normal width, no interior walls are load-bearing.
Sectional drawing is good.
Here are the original drawings! The house has been remodeled since then, but it's the wall between "Bedroom 2" and the hall that is to be removed. (Above where it says "raised floor")
Yes, I've also heard that this should be the case with single-story houses. But I become very uncertain since I've had more knowledgeable people than me look at it, and some say load-bearing - others say non-load-bearing.
That doesn't look like trusses, but rather like it is a load-bearing inner wall both in the basement and on the entrance floor.
How did it go with the wall, @Sandersson89 ?
