The first step toward replacing and installing a door is knowing its exact measurements. This includes the entry door’s height, width, and depth. Use the step-by-step guide below to measure your door properly.
Why Should You Measure An Entry Door?
The size of an exterior door impacts far more than just aesthetics. Exterior door size undoubtedly impacts safety and functionality, as well. A door that is too small may end up letting drafts in the house. A door that’s too big, meanwhile, won’t fit the frame properly.
Measuring the door isn’t simply about the slab itself, this also includes the frame and surrounding area. Measuring the door accurately can ultimately enhance your home’s comfort and overall value.
Tools Needed
For this task, there are a few items you’ll need to gather:
- Tape measure.
- Step ladder (for larger doors).
- A level.
- Pen, notepad, or phone to record the measurements.
How To Measure Your Entry Door
Now that you understand the importance of accurate door measurements and have gathered the necessary materials, follow these DIY steps below.
Step 1. Measure The Door’s Width
- Begin by measuring the exterior door frame’s width.
- Do this by opening the door and placing the tape measure at the inside edge of one side of the frame.
- Extend the tape measure to the opposite side.
- Take three different measurements at the top, middle, and bottom.
- Many older homes will feature uneven frames.
- Record the smallest number as this ensures the new door will fit within its narrowest point.
Step 2. Measure The Door’s Height
- Measure the height of the door by putting the tape measure on the floor to the top of the frame’s interior.
- Take three measurements from the left, right, and center.
- Again, use the smallest number here.
- This step is important because many times the floors or headers may be uneven.
- The average door height is 80 inches, but custom sizes can alter this measurement.
Step 3. Measure The Door’s Depth
- Do not overlook the depth or jamb width of the door.
- Measure the thickness of the wall where the door will be positioned, from the interior trim to the exterior edge.
- Average depths will be between 4.5-6.5 inches, ultimately varying based on the construction of the wall.
Conclusion
Measuring the entry door doesn’t have to be intimidating for homeowners. Simply follow the steps detailed above to properly measure the door width, height, and depth. Once you have the accurate data recorded, you will be ready for the installation of a new entry door.
For the best results possible, try measuring everything twice. Rember to never skip out on measuring the depth. Without this measurement, it’s possible the exterior door will not align with your wall.
