To measure for window film correctly, follow these steps:

Measure the Window:

Use a tape measure to determine the width and height of the window glass. Measure from edge to edge of the glass (inside the window frame) for accuracy. Make sure to measure both width and height in multiple places (top, middle, bottom for width; left, middle, right for height) to account for any irregularities.
Record the smallest measurement for both width and height to ensure the film covers the entire glass surface without gaps.
Calculate the Film Size:

Add an extra 1/4 inch (6 mm) to each side of the measurements. This extra allowance will help in trimming the film after application to achieve a perfect fit.
Order the Correct Size:

Use the adjusted measurements (with the added 1/4 inch) to order the window film. This ensures the film is slightly larger than the glass, making it easier to apply and trim to fit.
Special Considerations:

For multiple panes or unusually shaped windows, measure each section separately. Ensure you account for the layout and any specific installation requirements when ordering.
By following these steps, you’ll be able to order the right size of window film and avoid issues during installation.
