When it comes to installing doors, one of the crucial steps is framing. Proper framing ensures that the door fits securely and functions smoothly. In this article, we will discuss the essential measurements for framing doors and provide you with useful tips to achieve a professional result.

1. Door Opening Width

The first measurement you need to determine is the width of the door opening. Measure the distance between the studs on each side of the opening. This measurement will help you select the right-sized door for your space.

2. Door Opening Height

Next, measure the height of the door opening. Start from the top of the rough opening to the floor. This measurement will determine the height of the door you need to purchase.

3. Door Frame Thickness

Measure the thickness of the door frame to ensure it fits properly within the opening. This measurement is crucial for selecting the right-sized door jamb kit or frame.

4. Header Height

The header is a horizontal beam that supports the weight of the wall above the door. Measure the height of the header to ensure it is tall enough to accommodate the door and any additional weight it may bear.

5. Jack Stud Length

Jack studs are vertical supports on each side of the door opening. Measure the length of the jack studs to ensure they are long enough to reach from the bottom plate to the header.

6. Rough Opening Width

The rough opening width is the distance from one side of the jack stud to the other. This measurement should be slightly larger than the width of the door to allow for adjustments and proper installation.

7. Rough Opening Height

Similar to the rough opening width, the rough opening height should be slightly taller than the actual door height to allow for adjustments. Measure this distance from the top of the rough opening to the bottom plate.

8. Shim Thickness

Shims are used to level and secure the door frame within the rough opening. Measure the thickness of the shims you plan to use to ensure they fit properly and provide adequate support.

9. Clearance Measurements

Consider any additional clearance measurements you may need, such as the space required for door hardware, weather stripping, or hinges. These measurements will help you determine the overall dimensions of the door frame.

10. Double-Check and Adjust

Lastly, double-check all your measurements and make any necessary adjustments. It’s crucial to ensure accuracy before proceeding with the door installation to avoid any issues down the line.


By following these framing measurements for doors, you can ensure a smooth and successful installation. Remember to take accurate measurements, consider clearances, and make any necessary adjustments. With proper framing, your door will fit perfectly and function flawlessly for years to come.
