Measuring Instructions: Vertical Blinds for Bifolding Doors

Vertical blinds can be fitted on the inside recess or outside recess of bifold doors.

Tips
Use a metal tape measure to ensure accurate measurements.

Stacking Options & Stacking Sizes

For large vertical blinds it is important to know how much room is taken up by the louvres when they are stacked together.

Slat Size

There are two slat sizes to choose from, 89mm and 127mm. Vertical blinds with 89mm slats contain more louvres than those with 127mm slats.

Sometimes people opt for 127mm slats as there are less slats and therefore a smaller stack.

However there are a larger choice of fabrics for 89mm slats.

Outside Recess

This is a good option if you do not want to obstruct the glass with the blinds when they are open or the doors open inwards.

Fitting vertical blinds on the outside recess allows you to draw the blinds fully open past the door recess so the louvres sit over the walls rather than the door recess. Face fix brackets are needed for this fit.

Width

When measuring the width you want the blind to be on the outside recess you need to consider the stacking depth. This will depend on the slats width, and the opening you have chosen.

Once you have measured the width at the top where the vertical blind track will be fitted, use the table below to determine the stacking depth. Check whether the stack is likely to fit in over the wall and whether that is suitable for you.

Drop
Measure the drop from when the track will be fitted to where you want the fabric to finish.
Measure at at least 4 points across the doors ans use the smallest drop. We recommend the fabric to finish an inch above the floor.

Inside recess

When fitting vertical blinds in the inside recess they fit neatly in the recess space as shown below.

Width

Measure the width of the inside recess at 3 points, making sure the top of the recess and the skirting recess are measured.

Use the smallest measurement.
