Measuring Width & Height

Measure the desired width of the shade

Use a measuring tape to determine the desired width of the Roman shade. Start from one edge of the window frame and extend to the other side. Ensure that you measure straight across for accuracy.

Add extra width for better coverage

Add extra inches to your measurement. This ensures better coverage and minimizes light gaps. Typically, adding 2-6 inches on each side works well.

Measuring Height

Measure from the top of the window frame to the desired length

Measure from the top edge of the window frame down to where you want the shade to end. Use a sturdy measuring tape for precise results.

Add extra height for mounting hardware

Include additional inches in your measurement. This accounts for mounting hardware and ensures proper installation. Adding 2-6 inches above your desired length is usually sufficient.
