How to Measure for Bi-Fold Door Blinds

Bi-fold doors are brilliant at allowing light in. As a result, you are often left praying for a little more privacy or scrambling around searching for shade, especially in summer.

Choosing to invest in blinds for your bi-fold doors is a sensible solution. Not only will they help combat the above but they will add colour and texture to your space.

We have a range of styles and designs to choose from, but first, we will require the measurements you desire. To assist you in this process, we’ve come up with some swift and handy tips for measuring for bi-fold door blinds.

Here’s our handy guide to get you started for measuring for bi-fold door blinds:

1. Equip yourself with the right tools

First and foremost, you will need a few things to make this process as seamless as possible. When measuring for bi-fold door blinds you don’t need much expertise or any professional equipment - just these things from the list below:

  • Quality Steel Tape Measure
  • Pencil or Pen
  • Notepad
  • Butter knife or credit card

2. Check your bi-fold doors for blind suitability

Initially, what you’re looking for is a seal that runs around the perimeter of the window, where the glass meets the frame. This is known as a gasket. For our blinds to work the gasket needs to be rubber rather than foam.

The next step to confirm whether your bi-fold doors are eligible for blinds is to take your butter knife or credit card and slide it beneath the gasket. If you’re having difficulty, you could try lubricating your tool with some washing up liquid. However, don’t force it. Some gaskets are stuck into place and, if this is the case, your window isn’t suited for our blinds.

If you do manage to slide beneath the gasket, make a mark on your credit card or butter knife at the depth it enters. If this mark measures at least 10mm (1cm) it means that the blind tab will fit under it and fix in place, as long as your gaskets are not loose or soft.

3. Measuring for bi-fold door blinds

Before you dive in and place an order for your bi-fold door blinds, it’s crucial you make the most accurate measurements you can. To do so, follow these next steps, carefully:

Measuring width for bi-fold door blinds

For this stage, you need to be measuring the visible glass - the width of the window from gasket to gasket on each panel. We’d recommend measuring this in 3 places along the window (top, middle and bottom). Once complete, note down the shortest of the 3 in centimetres (cm).

Measuring length for bi-fold door blinds

Now it’s time to measure the length or the ‘drop’. Repeat the method you applied for measuring the width but this time you will need to take 3 measurements (left, right and centre), again recording the shortest result in centimetres to the nearest millimeter. This will be the length of the bi-fold door blind you require.

4. Check your measurements

To negate any disappointment, we always encourage you to double check your measurements. Sometimes simple mistakes are made which result in ill-fitting blinds. It’s best to be entirely accurate at this stage, then you can relax and leave the rest to us.
