King Post Truss Plans


SKU: 3286 Category:

These timber frame king post truss plans can be used for the roof trusses in your great room or master bedroom. It is one of the simplest forms of truss in that it is constructed of the fewest number of timbered members other than the common truss. The truss consists of two diagonal members call struts, one horizontal beam that serves to tie the bottom end of the two rafters together, and the king post which connects the peak to the horizontal beam below.

This instant-download PDF  package of 11 pages of drawings, materials lists and renderings makes this a fantastic project for any DIY craftsman who wants to learn about timber frame construction techniques from the ground up. Whether you rest this truss on conventionally framed walls or incorporate a timbered post to the truss, it will surely add to your space.

The width of the plan is measured from outside edge of rafter to outside edge of rafter.

Geoff Bury
Great plans. Printed off on 8 1/2 x 11 sheets and very legible and crisp. Colored individual piec...

Paid for the plans and immediately able to download. Printed clear and crisp on 81/2 x 11 paper individually colored pieces very helpful to showing the design. Thank you.

Ryan Sims
Great plans, need more info when buying.

These plans are some of the best out there. Only downfall for me personally is I bought them to make a 3 bent system with a ridge beam. These do not allow for a ridge beam. Not a big deal but there wasn’t enough detail in the description to tell exactly what was being sold.
