Measuring your Shade Sail's site


If all your fixing points are approximately on the same 'level' then that is absolutely fine - small changes in height (+/-300mm) can usually be taken up with the adjustable tensioners when installing the sail.  Our standard Shade Sails are designed as two dimensional sails (i.e. in one 'plane'- that is flat, or sloping in just one direction).  They may be flat, or at a sloping angle (like a pitched roof) - although this will depend on the requirements of your site and how the fabric sheds water.

PLEASE NOTE, If you are designing a bespoke sail that slopes in more than one direction and you have not defined the fixings as being at different heights, you may find the Shade Sail doesn't fit correctly.

The other alternative is to request one of our 'Hyperbolic' or 'Anticlastic' 3D shaped garden shades, and for this your imagination is the limit!  Our specialist software allows anchorages to be placed at widely different heights relative to each other and the fabric stretches into smooth curves between these points.  The effect of this is very pleasing 3D curves and modern shapes.  Use our dowloadable measurement form to help you with this (see the link on the left).  

If you have your fixings in place already, this will be a simple job.

1. Sketch out the area and label each corner with a letter, clockwise around the perimeter - ideally starting from the top left hand side (see diagram below).


2. Using a 'non-stretch' tape, measure a direct line from the centre of each fixing ring to each of the perimeter fixing rings in turn, and record them on your sketch.

For all four (or more) sided shapes, you will need to finish up with measurements for each edge of the Shade Sail, plus:

3. A measurement taken from any ONE corner to EVERY other corner between the fixings. Using this method of measuring will enable us to accurately recreate your shape in our CAD design program, without you having to measure any angles!

4. It is always wise to double check your measurements!


To create fixing points for one of our range of standard Shade Sails, use the diagram above as a guide - start with your choice of Shade (in this case a 3m x 4m x 5m) and draw imaginary lines from the centre of each side through each corner and extend outwards by approximately 210mm (for the nominal length of the fixings). This gives you the correct locations for the fixing points at the appropriate distances, and the Shade Sail should tension evenly without creasing.

Installation guidelines

On receipt of your Kemp Shade Sail, you should be able to get it out of its wrapping and fix it in place without any special tools - all you’ll need is a screwdriver to tension the rigging screws and perhaps a pair of pliers to deal with split ring fixings.

Please Note: It is a good idea to add some lubrication (Teflon, grease, vaseline or similar) to the threads of the rigging screws, as Stainless Steel threads are often prone to 'binding' or locking up. The lubrication will avoid this.

Simply attach the rigging screws to each anchorage, and attach the corners of the Shade Sail to the anchorages in turn. Then tension each rigging screw equally at each corner until the Sail is taught and any creases have been removed - note that this stage may require a small amount of ‘adjusting’ to get right. Finally, tighten the locking nuts to prevent loosening.

Placing the fixings themselves requires some basic DIY skills and rudimentary tools:

- An electric drill.
- A ladder or steps.
- A screwdriver or spike, for turning the body of the rigging screw/turnbuckle.
- A spanner or pliers, for securing the locking nuts
- A length of rope, for pulling the shade up to the fixing before attaching the rigging screw/turnbuckle (almost as good as a spare pair of hands!)
