Again, measure both corners and the center to account for any discrepancies.

Determining the Door Swing Space

Understanding the door swing is crucial for proper installation. Measure the space available for the door to swing open:

Open the door to its intended position.
Measure the distance from the pivot point to the nearest obstruction (like a wall or fixture).
Ensure there is enough clearance for the door to operate without interference.

Creating a Measurement Table

To keep track of your measurements, use the following table format:

Measurement Type	Location	Measurement (inches)
Width	Top	____
Width	Bottom	____
Height	Left	____
Height	Center	____
Height	Right	____
Door Swing Space	Distance from Pivot	____

Final Considerations

Once measurements are completed, review them for accuracy. Consider factors such as:

Wall irregularities that may affect the fitting.
The type of shower door you plan to install, as each may have specific requirements.
Local building codes that may dictate certain dimensions or installation practices.

By following these guidelines, you will ensure a precise measurement for your shower door installation.

Gathering Necessary Tools

To achieve accurate measurements for your shower door, gather the following tools:
