How to Measure Perfect Fit Blinds?

Step 1: Are Perfect Fit Blinds Suitable for Your Window?

First you will need to find out whether perfect fit blind is suitable for the frame of your conservatory, window or door.  

The brackets which will secure your blind in place are only compatible with internally beaded PVCu window frames, which have been sealed with glazing gasket. 

Most modern windows are internally beaded, due to safety legislation.

However, glazing tape is often used by rather than glazing gasket as it's cheaper for the window or conservatory manufacturer.  

Please Note: If your beading surround width is greater than 26mm then the Perfect fit Frame may not cover your beading completely and it may not sit flush on your window frame.

Unfortunately, if your window is externally beaded or sealed with glazing tape, then it will not be possible to install Perfect Fit Blinds.



Step 2: Check for Obstructing Handles.

Measure if there is a 27mm clearance all around the frame of the window frame, especially where there is a handle.





Step 3: Measure the GLASS SIZE in mm.


To do this, measure the actual visible glass WIDTH and DROP as accurately as possible.


TIP: We recommend using a digital measuring tape if possible and to measure in both corners and the centre of the window and use the smallest measurement in each direction.

Step 4: Measure the WINDOW FRAME DEPTH in mm.

To do this, we recommend using a Depth Gauge. This gives a measurement from the glass to the face of the window frame where the clip-in brackets will be fitted.

Perfect Fit Step 4: Measure the WINDOW DEPTH in mm

Based on the WINDOW FRAME DEPTH that you provide, we will select the appropriate bracket size, as follows:

  • If your WINDOW FRAME DEPTH is between 14mm to 17mm, we will send 18mm brackets + Padding Foam.
  • If your WINDOW FRAME DEPTH is 18mm, we will send 18mm brackets .
  • If your WINDOW FRAME DEPTH is between 19mm to 20mm, we will send 20mm brackets.
  • If your WINDOW FRAME DEPTH is between 21mm to 22mm, we will send 22mm brackets.
  • If your WINDOW FRAME DEPTH is between 23mm to 25mm, we will send 24mm brackets.
  • If your WINDOW FRAME DEPTH is 26mm to 30mm, we will send 30mm brackets.
  • If your WINDOW FRAME DEPTH is up to 38mm, we will send 38mm brackets. .

How to Install Perfect Fit Blinds?

We will supply a kit for each window pane that you have provided measurements for, including the required number of brackets of the appropriate height. (Note: these brackets can be exchanged if incorrectly specified.)

Step 1: Unwrap Your Blind

Carefully unwrap the parcel, taking great care not to cut any of the cords, if using scissors or a knife. Lay out the frame on it's front face, with the closed blind at the top.

Step 2: Fit Corner Joints

Slide each Corner Joint into the Vertical and Horizontal frame pieces to create a rectangular frame.

Do this by pushing the protrusions into the groove in the aluminium lengths until they are fully inserted. Then tighten the small screws to secure all four corners in place. Make sure you do not trap any loose cords whilst doing this.

Step 3: Fit Corner Covers

If not already fitted, install the corner covers by pushing over the corner of the frame and securing at the back using the screws provided.

Step 4: Fit Brackets to your Window


Use a credit card or the measuring card provided. 


Place the card in the top left hand corner of the visible glass area to find the correct position to install the 1st bracket.


At the bottom edge of the card, slide one of the brackets under the glazing gasket  until is tight up against the bead.


TIP: Light lubrication with washing-up liquid may make this easier in some cases


Repeat in all four corners of the window pane.


This will ensure alignment with the holes in the frame members. (Note: in extra tall or extra wide windows, additional brackets may be necessary in intermediate positions, and will be automatically supplied)
