Step 1: Measure the inside width at the top of the window. This is your ordering width. We will make the necessary deductions (approx. ⅛").
Step 2: Measure the height at 3 locations - the left side, middle and right side. Record the largest of the 3 measurements. This is your ordering length.
Note: Roller/solar shade fabrics will be approximately 1⅜" narrower than your ordering width to allow for brackets. If concerned over resulting light gap, please select outside mount.
Step 1: Measure the width of the area you wish to cover. If space allows, we recommend adding 3"-4" (1½"-2" each side) to this measurement to help eliminate light seepage. This is your ordering width and will be the overall measurement outside bracket to outside bracket.
Step 2: Measure the height of the area you wish to cover. This is your ordering length.
Note: Your shade fabric will be 1¼" narrower than the measurement you provide to allow for brackets. If you need the fabric to cover a specific width (e.g., for mounting the shade on a door), add 1¼" to the desired fabric width to find your ordering width.
