I am looking to order venetian blinds for my conservatory. I already have vertical blinds up and was going to use the measurements from the rail size and drop of these would this be correct.
Well the principal is the same however the brackets differ by 2.3cm in length as indicated below.
Personally I would re measure, allowing for this as it will affect window coverage in the apex centres, and on any 90 degree angles possibly.
I have provided the link to the how to measure pages below, the UEB bracket shown below is the correct bracket dimension to provide handle clearance of 4cm behind the blind. [See PDF]
