On the face of it, it may seem complicated, be reassured  though, it’s not. Taking the correct measurements is important as it can be an expensive mistake if you get it wrong. Get it right though and you’ll have the perfect balustrade for your home or business, for stairs, balconies, garden decking, restaurants, bars, shops and so on.

So, lets get started. How do you correctly measure for a glass balustrade?

Draw your plan – we always advise that you begin with good planning. Draw of where you want the glass balustrade system to be installed. It doesn’t need to be a technical drawing, or to scale. This is the starting point you can then add your measurements to your plan.This helps as then you can also identify where if there may be some difficult places in your design. Also, you should include dimensions of supporting walls, doors etc

Mark on where the end and corner balustrade posts will be – similar to other construction projects, there are some basic, but vital components that form how the installation fits together.
So on your plan, mark the end posts and any corner posts at 75mm distance from the edge.

Add the middle balustrade posts – these posts do what it says on the tin, they are the middle posts that go in between the corner and end posts and you should plan these in between 1,000 and 1,200mm apart.

Glass panels for your balustrade – when you have planned the posts, you can then calculate the width of the specialist glass panels. These are situated between the posts and you calculate this by measuring from one post to the other, (so, from the centre of one post to the centre of the next post). Once you have this measurement you would then deduct 90mm.
The reason you deduct 90mm is to allow for the following – a 21mm tube, 15mm for the glass clamp and 9mm clearance. This is then doubled to take into account both sides. Does this make sense?

The height of your glass balustrade – the height of a standard glass balustrade is 1,100mm.
Should you want your height to be something other than this you will need to speak to our team.

Select your balustrade components – you can now decide on the style of balustrade you desire which will determine a number of things, do you want a top handrail, would you like a frameless glass balustrade? We will assist you with all your fixtures and fitting, glass clamps, handrail etc etc.
