If you have less than 60mm of unobstructed depth, you’ll need to face fit, which
can be done with a Face Fit Frame that fits on your architrave or around your window.
You still need to take three measurements for height and three measurements for
width, but for face fit you measure to the outside edge of where your shutter frame
needs to sit and when you confirm your measurements with us, give us the largest
measurements and we’ll provide exact to that size.
