Using a tape measure, note down the height of your door from top to bottom in inches. Measure from the top edge of your door frame to the bottom edge. Measure the width of your door from side to side in inches. Start by measuring from the left-hand side of your door frame and jot down each measurement until you reach the right-hand side.

Step 3: Measure the Distance from the Door’s Edge

For your new door to fit correctly, measuring the distance from the edge of your existing door to the center point of its knob is important. To do this, measure from each side and jot down both measurements in inches.

To ensure your replacement door fits correctly, you should also measure the distance from the edge of your existing door to its lock or latch. Measure both sides and jot down each measurement in inches.

Step 4: Measure Your Existing Door’s Thickness

Measure the thickness of your existing door from top to bottom in inches. This measurement is important for choosing your replacement door, as the correct size must match the jamb’s width and depth. Using a tape measure, measure the height of your door jamb from top to bottom in inches. Measure the top part of the jamb to the floor below.

Step 5: Measure Your Door Jamb’s Width

Measure your door jamb’s width in inches, starting at one side and noting each measurement until you reach the other side. This measurement is necessary when selecting your replacement door. Measure the thickness of your door jamb in inches from top to bottom. This measurement should match the measurements of a new front door to ensure a correct fit.

Step 6: Record All Measurements

Once all the measurements have been taken, recording them in a safe place is important. This will help when selecting your new front door that perfectly fits your existing jamb and frames.

Now you know how to measure your front door for replacement. You can choose the perfect new door for your home with all the necessary information.

Precautions for How to Measure a Front Door for Replacement

  3. When measuring the door, use a tape measure or yardstick for accuracy and precision to get the right measurements of the replacement door.
  4. Make sure to double-check your measurements before ordering a replacement door to make sure that you have the correct size for your home.

What Type of Locks and Security Hardware Do You Need for the New Door?

When looking to replace your front door, it is important to factor in the type of locks and security hardware you need for the new door. This includes considering what type of lock you want, such as single-cylinder or double-cylinder deadbolts. Additionally, look at other types of security hardware, such as peepholes and knockers. Remember also to consider security features such as motion-activated lights and doorbells. These will help you feel more secure when entering your home.

Another important element when replacing a front door is the type of frame that it sits in. It may be necessary to replace or repair the existing frame depending on its condition, so factor this in when taking measurements. If a new frame is needed, note the dimensions of the door opening and account for any additional materials that may be needed, such as trim or sill plates.

Will There Be Any Additional Installation or Framing Work Required?

Once you have selected the replacement front door that best suits your needs, consider any additional installation or framing work required. Depending on the door type and frame you select, some modifications may be necessary to ensure a perfect fit. For instance, if you choose a pre-hung model with its frame attached to the door already, you may need to adjust the width of the frame or alter your existing opening if it is not wide enough.

If you decide to buy a door slab without any attached frame, you will also need to purchase and install a separate door jamb that meets your specifications. These additional components and installation work are important but can be made significantly easier when you hire a qualified professional. Professional installers have the expertise and tools to size up your existing opening and make any necessary modifications for a perfect fit.

Are There Any Local Building Codes or Restrictions to Consider When Replacing a Front Door?

Before you measure your front door for a replacement, it’s important to check any local building codes or restrictions that may affect the type of door or material you can use. Depending on where you live, different areas may require certain materials for a front door replacement, such as metal or fire-resistant wood.

If you’re unsure whether local building codes or restrictions apply, it’s best to check with your local municipality before you begin measuring your front door for replacement. Doing so can save you time and money in the long run by ensuring that the door you purchase is compliant with any local regulations.

To ensure you get the correct measurements for a replacement front door, it’s important to measure your existing door’s width and height. You should also consider any moldings or locksets that may be present on the existing door, as these can affect the size of the new door you need.

What Type of Material Should You Choose for the Door?

When it comes to choosing the material for a replacement front door, your main considerations should be security, durability, and aesthetics. Steel is one of the best materials for a front door due to its strength and resistance to weathering, while fiberglass or wood can provide an attractive look while still being strong and secure.

It’s important to pick a material compatible with your home’s style. For example, if you live in a traditional-style home, wood might be the best option as it provides an elegant and timeless look. Steel or fiberglass may be better choices if you want something more modern.

In addition to security and aesthetics, you should also look at the door’s energy efficiency. If you live in a colder climate, an insulated steel door can help keep the heat inside your home and reduce energy costs. On the other hand, if you live in a warm area, you should consider investing in a door with built-in ventilation features to help cool down your home.


Replacing your front door can be a costly and time-consuming process. There are many steps to get the right-sized door for your home, including measuring the door frame, selecting the desired materials, and hiring a professional contractor.
