How to Build a Platform Bed for $50 – FREE PDF Plans!

If you’re looking to build a simple and modern platform bed, we’ve got you covered with this post. It’s an affordable and approachable project for anyone!

Today, we’re showing you the easiest way to build a platform bed with legs! This project is so easy and makes a huge impact.

We have been making over our guest bedroom, with furniture builds like midcentury side tables and a console table, and a color block wall.

The old dark wood 80’s bed just wasn’t going to cut it, so we built a platform bed in one day for less than the cost of Thai food takeout.

DIY Platform Bed

The main thing to consider with a platform bed is how high you want it to be from the ground.

We chose 9 inches because we have our rolling under-bed storage for wrapping paper underneath.

It was important that our platform bed have legs so that we could take advantage of that precious storage space!

When making your measurements for a platform bed, the inner dimensions of your bed frame need to be the same dimensions as your bed.

We built this for a double/full size bed, and the standard dimensions are 53″ x 74″.

How much does it cost to build a platform bed?

There are a few factors that will determine how much it costs to build your platform bed. The main one is type of lumber used.

We built this bed for $50 worth of wood. For transparency, that was in 2019. Since then, lumber prices have skyrocketed, but it should still be relatively inexpensive to build this bed, especially compared to purchasing one.

The second factor is what tools or supplies you have on hand or can borrow. We built this double sized bed for just under $50 worth of lumber – we had all of the tools on hand already.

It will cost you more if you don’t have stain, screws or a pocket hole jig on hand, but that won’t add much to the cost.

Want to make this bed in a different size?

We sell the plans to build a King sized platform bed, a Queen sized platform bed, or a twin sized platform bed! Or, buy them all as a bundle!

How to build a platform bed frame

There are lots of ways to build a platform bed with all sorts of styles. This is a simple box bed with legs and slats. Here’s the overview.

We started by cutting and sanding all our wood to the dimensions needed (see the how-to card below for the full cut list).

Here are a bunch of beds that you can build using a Kreg Jig!

Cuts needed for DIY platform bed
These pieces are laid out how they will attach. Basically fold them in and screw!

All the pieces in this build are attached using a Kreg Jig.

I usually use the Kreg 720 Pro, but since these are big, long 2x6s, it is a lot easier to clamp on the brand new Kreg 320 directly to the wood.

I absolutely love the 320. It is super user-friendly and great for beginner woodworkers.

The 320 has a thickness gauge which allows you to determine the exact thickness of your wood and then set everything on the 320 to that thickness.

You can set the jig itself and the stop collar on the drill bit to the same dimension to avoid any miscues.

This will also tell you what length screw to use. For the 2x4s and 2x6s used in this project, you need to use 2 1/2 inch Kreg screws.

Steps to Build a Platform Bed

First step was to build the outside box frame by connecting the four sides of the bed.

Next, we attached support railings along the insides of each side of the frame.

Since we were using 2x4s, we subtracted 7 inches from the long sides and 3 inches from the short sides to account for the other pieces.

Attaching supports of DIY platform bed

We added legs to the bottom of the 2×4 supports along the front and back.

We cut the same angled legs as we did on our DIY midcentury crib and IKEA Hemnes dresser hack.

The last step is to add the support for the mattress.

We attached two more 2x4s down the middle length of the bed and then laid 1×4 slats across the width.

Final Results

We popped the mattress into the frame and it fit perfectly. We’re keeping the comforter and everything tucked down into the frame so that it stays prominent.

We love how this DIY platform bed turned out. It is sleek and modern and takes up much less space than the old bed.

This build might seem like a larger-scale build, but it was extremely simple. It’s a box with legs!

This is a great beginner woodworking project to really get you feeling like a pro. It was all made so much easier thanks to the versatility of the Kreg 320 Jig.

What is the best wood to use for a platform bed?

You can use any species of wood to build this platform bed. We chose pine because it is the cheapest wood at the hardware store and we wanted to complete this project on a small budget.

Do I need a special mattress for a platform bed?

No, you can use any mattress on this bed. Just don’t use a boxspring, which saves you money! That is the beauty of a platform bed – the mattress sits directly on the wood.

We're showing you how to build a platform bed for only $50 in materials. If you've ever wanted to switch to a platform bed and ditch the box spring and huge headboard/foot board, this is what you need. You can build this platform bed in just a day. Please note, these instructions are for a double/full size bed. If you want to build a platform bed for a twin, queen or king mattress, you can use the same instructions, but you'll need to scale them appropriately.

  3. Attach the Sides to the inside edge of the Front and Back.

The plans call for the front boards to be cut at 56" and the supports at 53", but all of the FULL mattress dimensions I see show them to be 54" wide, which would seem to be an inch wider than the resulting opening on this bed... I realize mattresses are not SOLID and will have some give, so is the 1" lacking intentional so that it fits snugger???


Thursday 19th of August 2021

Hey Chad, so my mattress is 53". If you look online, it seems to vary between 53" and 54", depending on the brand. I think a soft 54" mattress would fit snug with no problem, but if you wanted to adjust the cuts by 1", you could just adjust the front and back pieces and the slats by 1" each.

Nice plans and well laid out, still waiting for a gazebo plan. Thanks for the free plans you provide.

Thanks Gene! I wish we had space for a gazebo in our yard!

hey there! We built this bed and love it, thank you for the plans! The only issue we're having is the legs are pretty wiggly. We have the bed in a room with hardwoods and after sliding the bed over a little the legs became very shaky. Any tips on reinforcing them to make them more stable?


Monday 27th of July 2020

Hey Brooke - glad you are enjoying it. Do you mean wiggly like loose from the base? Did you apply wood glue between the legs + base before screwing them together? That would make the legs not-removable from the base, but would make a very tight bond. -Morgan
