Measuring a door for sizing may seem like a simple task, but getting it wrong can result in a door that doesn’t fit properly. Whether you’re replacing an old door or installing a new one, accurate measurements are crucial for a successful installation.
Before you begin, make sure to have the right tools on hand, including a tape measure and a pencil. Taking precise measurements will help you avoid costly mistakes down the line.
In this article, we will guide you through the process of measuring a door for sizing step by step, ensuring that you get the perfect fit every time.
Gather necessary tools
To properly measure a door for sizing, you will need the following tools:
– Tape measure: to accurately measure the dimensions of the door.
– Pencil and paper: to record your measurements for future reference.
– Level: to ensure that your measurements are straight and accurate.
– Step stool or ladder: to reach the top of the door frame if necessary.
Having these tools on hand will make the measuring process much easier and more precise.
Measure the width of the door
To measure the width of the door, use a tape measure to determine the distance across the door from one edge to the other.
Step 1
Start by positioning the tape measure at the left edge of the door frame and stretch it across to the right edge. Make sure the tape measure is straight and not twisted to get an accurate measurement.
Step 2
Take note of the measurement in inches and record it. This measurement will give you the width of the door, which is essential for selecting the right-sized door or determining if any adjustments are needed.
Measure the height of the door
To measure the height of the door, start at the bottom of the door and use a measuring tape to determine the distance to the top of the door frame.
Step 1: Stand in front of the door and place one end of the measuring tape at the bottom of the door.
Step 2: Extend the measuring tape vertically along the edge of the door to the top of the door frame. Make sure the tape is straight and not slanted.
Step 3: Note down the measurement in inches or centimeters. This measurement represents the height of the door.
Check the door jamb width
When measuring the size of a door, it is crucial to check the width of the door jamb. The door jamb is the vertical part of the door frame that the door hinges are attached to. To accurately measure the width of the door jamb, use a tape measure to measure the distance between the inside edges of the jamb. Be sure to measure in a few different places to ensure accuracy, as door jambs can sometimes be slightly uneven.
Tips for measuring door jamb width:
1. Measure the width of the door jamb at the top, middle, and bottom to check for any inconsistencies.
2. Ensure that the tape measure is snug against the inside edges of the jamb to get an accurate measurement.
Measure the door thickness
To accurately measure the thickness of a door, you will need a tape measure. Start by closing the door and locating the edge where the hinges are placed. Use the tape measure to determine the distance from one side of the door to the other. This measurement will give you the thickness of the door.
Determine the hand orientation of the door
Before taking any measurements, it’s essential to determine the hand orientation of the door. This refers to which side the door hinges are on when looking at it from the outside of the room.
To determine the hand orientation, stand outside the room facing the closed door. If the hinges are on the left side, it’s a left-hand door. If the hinges are on the right side, it’s a right-hand door. This information is crucial for properly measuring the door for sizing.
Measure for hardware placement
When measuring your door for sizing, it’s crucial to also take into account the placement of hardware such as hinges, handles, and locks. Properly measuring for hardware placement ensures that your door will function correctly and look aesthetically pleasing.
1. Hinges:
Measure the distance from the top of the door to the top of the hinge, as well as the distance from the bottom of the door to the bottom of the hinge. Make sure to account for any additional space needed for the hinge to operate smoothly.
2. Handles and locks:
Determine the height at which you want to place the handles and locks on your door. Measure the distance from the edge of the door to the center of the handle or lock. Make sure to maintain uniformity if you have multiple doors in your space.
Take into account flooring thickness
When measuring a door for sizing, it is important to consider the thickness of the flooring. If the door will be installed over new flooring or if the flooring will be replaced in the future, be sure to account for the added thickness when measuring. This will ensure that the door will still open and close properly once the flooring is in place. Measure from the bottom of the door to the floor, and add the thickness of the flooring to this measurement to get an accurate door size.
Double-check all measurements
After you have taken your initial measurements, it is crucial to double-check each measurement to ensure accuracy. This step will help eliminate any errors and prevent costly mistakes when ordering a door that doesn’t fit properly.
Measure each dimension at least twice to confirm consistency. Make sure to check the width, height, and thickness of the door frame, as well as the swing direction and any obstructions that could affect the door’s installation.
It’s also a good idea to have someone else verify your measurements to catch any oversights or miscalculations. Taking the time to double-check all measurements will save you time, money, and frustration in the long run.

Record and save measurements for future reference
Once you have accurately measured your door, it is crucial to record these measurements in a safe place for future reference. This will save you time and effort if you ever need to replace or repair your door in the future.
