Introduction: WhiteDoar

Hello to fellow thinkers, creators, teachers, and penny pinchers. Today, if you're willing to learn, I am going to do my best to help you get a whiteboard into your home, all while taking up as little space on your walls and as little cash from your pocket. I decided to use the back of a door as my canvas, since real estate on my interior walls is scarce and a door provides a decent amount of space to write on, all while being hidden.


Total cost ~35 (If you have to purchase everything)

-1 Sheet of 1/8-inx4-ftx8-ft Smooth White Hardboard

-3 PVC White End Caps 8ft

-1 Carpenters Knife

-1 4-foot Length of Adhesive-Backed Velcro (Ensure both Male and Female portions come in the kit and that the kit can support up to 10lbs)


-Combination Square (not necessary, but will help to make nice 45 degree cuts on End Caps)

Step 1: Purchasing Supplies

If you have a pick-up truck bypass the precaution.


Before going to the store I recommend bringing a carpenters knife and the longest straight-edge that you can if you do not have access to a pick-up truck. Most home improvement stores will not cut the whiteboard material in-store due to the white enamel/ polymer melting at high temperatures. You will have to make the cuts on the store floor with a carpenters knife.

Upon arriving at your home improvement store, determine what supplies you need and begin seeking them out. I have attached pictures of the products that I purchased so that you take the SKU to the store and request the same materials (Important note* I purchased from Lowes so SKUs will vary)

please refer back to the Supply List.

Step 2: Making Cuts

Interior doors are set by specific building codes so one projects dimensions should be consistent among most doors in the United States. Make your cuts based on the door you wish to attach the board. Be sure to take the doorknob into consideration. I personally cut my white hardboard to 78-inch x 30-inch to fit my door. Should you need to reference the building code site I used I will attach the resource below.

Step 3: Attach the End Caps

Once you have made your cuts, now it's time to clean up the edges by adding the end caps.

Be sure to measure the lengths of all four sides and mark those lengths on the end caps to make the caps the appropriate length. After making your cuts for the length, use a combination square to cut the ends of your caps to 45 degree angles (as seen in the attached pictures). You can make the 45 degree cuts by "eyeballing" it, but you may have difficulty getting your ends to line up perfectly. If needed make small adjustments/ shavings to the end of your caps with your carpenters knife.

Step 4: Adding the Velcro

Now that the hard part is done, its time to attach your board to the door. Layout your whiteboard and determine where the high points of the door are so you can properly adhere the board to the door. I cut my 4 foot length of Velcro into four 1 foot lengths of Velco that would work best with the design of my door (as seen in the picture). Every setup will differ depending on the door that you are adhering your board to.

Step 5: Remove Adhesive and Pressing to the Door

Once the male portion of the Velcro is set, place the female portion of the Velcro onto the male and peel the adhesive backing off. Now all there is to do is press it onto the door!

Step 6: Using Your WhiteDoar

Now that you have your whiteboard on the back of your door, you can begin writing your code, making your plans, and drawing your pictures all while being out of the way, allowing your friends to come in and out as they please.
