Farmhouse King Bed Plans

The bed that started it all. Some cleverly placed stud grade boards and some antique white paint, and I give you a sturdy, simple heirloom quality bed. Special thanks to Marion at The Bumper Crop for sharing her amazing photos.

General Instructions: 

Because the instructions to build this bed are essentially the same as the plans for the Queen sized (including the bed frame), I will just be providing diagrams on how to build the Heaboard and Footboard in the king size.
Please review the plans for the Queen Sized with Arch and the Queen Sized Farmhouse Bed plans before begining this project. Follow the plans for the Queen Size with Arch for building the side rails, if you do not have a metal bed frame. The length of this bed is identical (80″) to a queen size. If you do not have a box spring, you can use slats. Please review the post on the Twin Sized Farmhouse Bed here. There is lots of information here – look at the comments on how to add slats to the frame. The slats will be 80″ long, I would space them closer or use bigger boards, like 2x4s.

Please also take note that King beds vary in size depending on where you live. You should always measure your mattress first and make sure that it fits the bed. There are also California King bed plans available. The measurements given are recommended for a bed 80" wide. If your bed is narrower, simply trim off from the panel and panel trim boards, or substitute 1x6s for the end boards in the panel.

Also note that when you build with standard dimensional lumber, widths can vary greatly depending on where your lumber was milled. Always measure the width of your boards first. This plan assumes that your 1x8s are 7 1/2" wide - the widest possible measurement. Check yours, adjust accordingly.

Designed for mattress measuring 80" wide
Cut List: 

For the Headboard, you will need:
Panel Pieces (center) 10 – 1x8s @ 30″
Panel Pieces (ends) 2 – 1x3s @ 30″
Panel Trim Pieces – 4 – 1×4 @ 80″
Legs – 2 – 4×4 Posts @ 54″
Bottom Header – 1 – 2×4 @ 87″
Top Heaer – 1 – 2×6 @ 89″

For the Footboard, you will need:

Panel Pieces (center) 10 – 1x8s @ 15″ (Green)
Panel Pieces (ends) 2 – 1x3s @ 15″ (Pink)
Panel Trim Pieces – 4 – 1×4 @ 80″ (Blue)
Legs – 2 – 4×4 Posts @ 21″ (Purple)
Bottom Header – 1 – 2×4 @ 87″ (Yellow)
Top Heaer – 1 – 2×6 @ 89″ (Orange)

Cutting Instructions: 
I highly recommend cutting all of your panel boards first and taking a measurement, and then cutting the panel trim boards to fit that measurement.
Step 1: 

Construct your headboard.

Step 2 Instructions: 

Construct your footboard.

Step 3 Instructions: 

When assembling your bed, you may have two seperate boxsprings. What I did was build a "floor" out of 2x4s for a frame (see queen bed) and then put plywood on top, followed by the mattress. We have never had a support issue. If you feel you need to have extra support (king beds are big, I know) you can simply add a fifth "leg" in the center of the bed from scrap 4x4s. This will beef up the support considerably.

Ana I love your plans.  I have built a coffee table, farmhouse table, and now this bed.  I noticed in the comments that several people would like the regular dimensions for a standard king.

Here is what I did:

First of all. Yes instead of 4 1X8's you will need 5 I cut 9 1x8 boards at 30'' for the head board pannel pieces.  I cut 9 1 x 8 pieces at 15 '' for the foot board.  NOTE: instead of using 1x3's at the ends of thepannel pieces.  I cut 2 1x6 boards at 30'' and 2 at 15'' to replace those.  That way it off sets the 4 inches for the head board and foot board to make it 76'' instead of 80''.

The rest of it was pretty easy:  I just took off 4 inches on the long items ie:

Instead of the panel trim pieces "4 1x4 at 80''  I made them 76 inches

For the bottom header inseat of 87'' i made it 83'' (headboard and foot board"

For the top header instead of 89'' i made it 85'' (headboard and foot board)

I hope this is not confusing.  I also used 2x4's at roughly 72 inches and then some begboard as a "box spring and support" for my 12 inch memory foam mattress.  I will upload a pic when I can.
