A Guide to Perfect Fit Shutter Panels

Depending on the size of your window, the number of shutter panels will vary. You will also need a 'midrail' if your blind is over a certain size.

The guide below explains how many panels will be required depending on both the glass size and the location of the window's handle (if it has one) :

Window Handles

  • If the handle on your window is on the left or the right hand side, this will have no effect on the number of panels required. 
  • If the handle is located at the bottom of your window, you will always have to have an odd number of panels so that the handle is not positioned where two panels join.

For more information on handle positions please click the ? icons next to 'Window Handle Location' and 'Handle Position' on the product page when configuring your shutters.

Perfect Fit Shutter - Single Panel

Single Panel

Visible Glass Size - 30cm to 75cm Wide


If your window has a visible glass size of between 30cm to 75cm wide, you will require one single shutter panel.

If you have a handle, we will include a rounded indentation in the frame to allow the handle to still move and operate when the shutter panel is in place. This can be located at the left, the right or at the bottom.

Perfect Fit Shutter - Double Panel

Double Panel

Visible Glass Size - 75.1cm to 150cm Wide


If your window has a visible glass size of between 75.1cm to 150cm wide, you will require two shutter panels to cover the glass. They will be joined with a subtle vertical bar.

If you have a handle, we will include a rounded indentation in the frame to allow the handle to still move and operate when the shutter panel is in place. This can be located at the left or the right, but not at the bottom. If your handle is located at the bottom, you will require three panels so the handle doesn't sit on the join.

Perfect Fit Shutter - Triple Panel

Triple Panel

Visible Glass Size - 150.1cm to 225cm Wide


If your window has a visible glass size of between 150.1cm to 225cm wide, you will require three shutter panels to cover the glass. They will be joined with a subtle vertical bar between each panel.

If you have a handle, we will include a rounded indentation in the frame to allow the handle to still move and operate when the shutter panel is in place. This can be located at the left, the right or at the bottom.

Midrails

If your blind has a drop of 160cm or over, you will need a midrail on each shutter panel. This means that the top and bottom sections of slats are controlled independently with their own handrails.

The midrail will always be positioned at the halfway point, so for example if your shutter has a 160cm drop the midrail will be located 80cm from the top.
