Perfect Fit Measuring Guide
This guide is suitable for uPVC windows and uPVC doors only. It covers the unique method of measuring for no-drill, Perfect Fit shutter blinds. Take a look through our handy guide to ensure your measures are accurate.
What you’ll need:
- Steel tape measure
- Pen or pencil
- Paper
- Credit or debit card
Preparation
Each section of glass will require it's own shutter blind. For example, the window shown below would require you to order 2 shutter blinds. You can use our 'create similar' button from the basket to speed up the ordering process.
Perfect Fit shutter panels will clip directly onto your window frame. Before you start measuring, please check for obstructions on your window such as handles or vents. You'll need to have 25mm of clearance around the glass.
For further information on the configuration of specific shutter ranges, please make sure you read the "Product Spec" on the product pages.

To measure for Perfect Fit on bay windows, measure each section of your bay individually — each one will require its own shutter.
The easiest way to do this is to create your first section, add it to your basket, then select “Create similar” to duplicate it and adjust the dimensions for the rest of your window.
Step 1 - Measure the width
Measure from the inside edges of the rubber beading in 3 places to find the smallest size.
Do not include any of the rubber beading or rubber seals in your measurements.
You don't need to make any tolerance deductions to your measurements.
Step 2 - Measure the height
Measure from the inside edges of the rubber beading in 3 places to find the smallest size.
Do not include any of the rubber beading or rubber seals in your measurements.
You don't need to make any tolerance deductions to your measurements.
Step 3 - Measure for midrails
If your height measurement is over 1500mm you'll need to include a midrail for stability. This is a horizontal rail dividing shutter blinds into two sections allowing independent operation of the top and bottom slats.
For shutter blinds between 550mm and 1500mm in height, a midrail is optional.
To position it, measure from the bottom of your window pane to the desired midrail center. It must be at least 275mm from both the top and bottom, however most place it centrally.
Please note: A midrail might need to be moved up or down by up to 45mm during manufacture to make room for as many slats as possible.
Step 4 - Measure the window rubber beading depth
Place a credit card over the corner of the frame and use a metal tape measure or ruler to measure from the glass to the edge of the card.
You are measuring the window bead depth in order to select a matching bracket size. The bracket sizes we offer are 18mm, 20mm, 22mm, 24mm, or 30mm.
If your window frame depth does not match one of these bracket sizes, we recommend choosing an alternative product as the Perfect Fit panels may not fit securely to your window.
Step 5 - Check the rubber beading
Check that the rubber beading does not overlap the glass by more than 6mm.
Optional step - Measure for handle cut outs
If your window has a handle, you'll need a handle cut out. You will be asked to specify both the location (left, right, top, bottom) and the cut-out depth when placing your order.
If the handle is on the left or right, measure from the bottom seal of the window to the centre of the open handle.
If the handle is on the top or bottom side of the window, take the measurement from the left seal to the centre of the open handle.
NB: Handle cutouts are only necessary for windows. They aren't required for handles on patio doors.
