How to Measure for Inside Mount

Inside mounted shades are installed inside the window frame, giving a clean and seamless look. Here’s how to measure for an inside mount:

• Measure the depth of your window frame from the front of the opening to the glass to ensure it meets the minimum depth requirement.
• Measure the width of the window at the top, middle, and bottom. Use the narrowest measurement as your window’s width.
• Measure the height of the window at the left, center, and right. Use the tallest measurement as your window’s height.

Order at the exact opening size — no deductions are needed; the factory will take care of adjustments.

Tip: Double-check that your measurements follow the width by height format (W x H).

How to Measure for Outside Mount

Outside mounted shades are installed above the window frame, allowing the shades to cover a larger area. Here’s how to measure for an outside mount:

• Check the mounting requirements for your London shades to ensure enough flat surface for hardware.
• Measure the width from the far edges of your window trim (or add 2–3 inches on each side for better coverage if there's no trim).
• Measure the height starting from the desired top of the window to the bottom where you want the shades to hang. If you want more coverage, add a few extra inches above the window.

Order at the exact size — your shade will be made to the specified dimensions.

Tip: Double-check that your measurements follow the width by height format (W x H).
