Are you planning to install a new screen door but don’t know how to measure for it? Not to worry, getting the correct measurements is essential for a perfect fit and optimal functionality. Whether you’re a seasoned DIYer or a first-timer, this comprehensive guide will walk you through the process of measuring a screen door like a pro. Follow these detailed instructions to ensure a seamless and successful installation.
To begin, gather the necessary tools, including a measuring tape, pencil, and notepad. The first step is to determine the width of the door frame. Measure the distance from the inside edge of one jamb to the inside edge of the other. Note this measurement in inches. Next, measure the height of the door frame, from the top of the threshold to the bottom of the header. Again, record this measurement in inches. These two measurements will give you the overall dimensions of the screen door you need.
Now, let’s account for any overlap between the screen door and the door frame. Typically, an overlap of 1/2 inch on all sides is recommended. Add this 1/2 inch to both the width and height measurements you obtained earlier. This will ensure that the screen door fits snugly within the frame. For instance, if your door frame measures 36 inches wide by 80 inches high, you would need a screen door measuring 37 inches wide by 81 inches high to accommodate the 1/2-inch overlap on all sides. By following these simple steps, you can accurately measure for a screen door that fits perfectly and provides years of reliable operation.
Measuring Diagonal Lengths
Measuring diagonal lengths is crucial for obtaining the most accurate measurements of your screen door. To measure the diagonal length correctly, follow these steps:
1. Mark the Corners
Using a pencil or chalk, mark the two diagonal corners of the door.
2. Measure the Length
Use a measuring tape or laser measure to measure the distance between the marked corners. This measurement represents the diagonal length of the door.
3. Example Measurement
To illustrate the process, consider the following sample measurements:
| Upper Left Corner | Upper Right Corner | |
|---|---|---|
| Diagonal Length | (24 inches, 48 inches) | (60 inches, 12 inches) |
| Measurement | 63.25 inches | |
In this example, the diagonal length of the door is 63.25 inches.
4. Using the Pythagorean Theorem
If you cannot measure the diagonal length directly, you can use the Pythagorean theorem to calculate it. The theorem states that in a right triangle, the square of the hypotenuse (the diagonal) is equal to the sum of the squares of the other two sides (the height and width). Thus, you can calculate the diagonal length using the formula:
Diagonal Length = √(Height² + Width²)
Considering Gaps and Clearances
Determining Vertical Clearances
Measure the height from the floor to the top of the door jamb in three locations: the center, left side, and right side. Take the shortest measurement as the vertical clearance.
Horizontal Clearances
Measure the width of the door jamb in four locations: the center, left side, right side, and top. Record the smallest measurement as the horizontal clearance.
Additional Clearances
Consider additional clearances for:
– Strips and Seals: Allow for 1/4″ to 1/2″ clearance around the perimeter of the door to accommodate weatherstripping.
– Latch: Measure the length of the latch and add 1/8″ to 1/4″ to allow for space to engage the strike plate.
– Hinges: Determine the thickness of the door and hinges, and allow for enough clearance to prevent the door from binding or sticking.
– Door Stop: If a door stop is present, measure the distance from the surface of the wall to the stop and add 1/8″ to 1/4″ for clearance.
| Clearance Type | Measurement Considerations |
|---|---|
| Vertical | Measure from floor to door jamb: center, left, right. Shortest measurement is vertical clearance. |
| Horizontal | Measure door jamb width: center, left, right, top. Smallest measurement is horizontal clearance. |
| Strips and Seals | Allow 1/4″ to 1/2″ around door perimeter. |
| Latch | Measure latch length and add 1/8″ to 1/4″. |
| Hinges | Account for door and hinge thickness, add clearance to prevent binding. |
| Door Stop | Measure distance from wall to stop, add 1/8″ to 1/4″ for clearance. |
Verifying Measurements
After determining the measurements, it’s crucial to verify their accuracy to ensure a perfect fit for your screen door. Here’s how you can double-check your findings:
Width Measurement
Take the width measurement again, this time from the outside edges of the door frame. This ensures you account for any overlapping or gaps that may occur when the door is installed.
Height Measurement
Remeasure the height from the top of the door frame to the threshold. Include any gaps or overlaps in your calculation.
Checking Diagonal Measurements
To verify the overall squareness of the door frame, measure the diagonals from corner to corner. If the measurements are not equal, there may be some misalignment that needs to be corrected before installing the screen door.
Table of Measurements
Create a table to record your measurements for easy reference:
| Measurement | Result |
|---|---|
| Width (Outside) | [Measurement in inches or centimeters] |
| Height | [Measurement in inches or centimeters] |
| Diagonal 1 | [Measurement in inches or centimeters] |
| Diagonal 2 | [Measurement in inches or centimeters] |
How To Measure Screen Door
To measure a screen door, you will need a tape measure and a pencil. First, measure the width of the door frame from the inside edge of the left jamb to the inside edge of the right jamb. Then, measure the height of the door frame from the top of the threshold to the top of the jamb.
Once you have the width and height of the door frame, you can add 1/2 inch to each measurement to allow for overlap. This will ensure that the screen door will fit snugly in the frame.
When you are measuring the screen door, be sure to measure from the outside edge of the frame to the outside edge of the frame. This will ensure that the screen door will be the correct size.

Where should you measure a screen door?
You should measure a screen door from the inside edge of the left jamb to the inside edge of the right jamb for the width, and from the top of the threshold to the top of the jamb for the height.
How much overlap should you allow for a screen door?
You should allow for 1/2 inch of overlap on both the width and height of the screen door.
What is the best way to measure a screen door?
