People sometimes wonder why we take deductions for some of our shades. These deductions are necessary to make sure that the shade covers the window properly; you don’t want the shade to hang up on the window’s frame. We’ve gone ahead and laid out our rationale behind the deductions for different types of shades. These have been time tested; so send us your measurements and we will take the necessary deductions.
For shades that are ordered as an inside mount without sidetracks, the fabric and rails are 3/8” narrower than they are ordered. This is done to make sure that both the shade and the end caps fit within the window’s frame.
Shades that are ordered with sidetracks, both the fabric and the rails are cut 7/8” narrower than they are ordered. This 7/8” is the space that’s taken up with the sidetracks and the end caps. If shades are mis-measured or the window's frame isn't a perfect square, small light gaps may exist.
Shades that have been ordered as outside mounts will have no deductions on both the fabric and rails. These will be cut to the exact size that’s ordered. This means that with end caps the whole unit will be slightly wider than it was ordered. We suggest that you order the shade larger than the glass you are covering, to ensure full coverage.
