Queen post truss
Two posts split the span, opening up a wider, taller room.
Split the king post in two and you get a queen post truss — two posts standing off-center, opening up the middle for a loft, a stair, or just air.
How it works
queen posts two, spaced in from the walls straining beam ties the two posts at the top tie beam carries the whole truss across the room span wider + taller than a king post
When to use it
Wide spans with an attic above. The two posts frame a useful central bay, so you can hang a loft floor off them instead of building a wall.
