Shade sail sizes from 4 to 36 square metres

Sorted by shape. Each size shows the area of the sail - not the area that ends up in the shade: when the sun is low, the shadow moves to the side. The sizes we sell most often are 3 x 4 m, 4 x 5 m and 4 x 6 m. A rectangular sail of 2 x 3 m, 2 x 4 m or 5 x 7 m is not one of our standard sizes - we sew these to order. If you are still choosing the shape, see square shade sails, rectangular shade sails, triangle shade sails and trapezoid shade sails.

Which size for which area

The usual mistake is a sail that is too small. Add half a metre on each side to the area you want in the shade - in Central Europe and the UK the sun is never directly overhead, even in midsummer, so the shadow falls at an angle. A small shade sail usually means the sizes up to 3 x 3 m; anything from around 20 m² of sail area counts as a large shade sail. A rectangle covers a narrow patio better than a square of the same area - with a rectangular sail, the longer edge decides how far the shade reaches.

Every size in three finishes

The sizes are the same in all three fabrics; the difference lies in water, weight and colour choice. We sew from tightly woven outdoor fabrics, not from HDPE fabric - the knitted shade netting of 160 to 220 g/m² that is often sold as a shade sail: HDPE is air-permeable and inexpensive, but it neither keeps rain out nor holds its colour over the years. Free fabric samples show the feel and the shade of colour before you order. What a water column tells you is explained in the guide What is a water column, what lightfastness means in the guide What is lightfastness.

From the area to the right size

1

Find the fixing points

Points first, then the size. House wall, post, tree - the distance between them is larger than the sail, because the fixings sit in between. Each corner has a stainless steel fixing ring that takes a snap hook and a turnbuckle. Allow 30 to 50 cm per corner.

2

Plan the slope

A sail is never tensioned level. A height difference of 25 to 30 cm per metre across the diagonal decides how the sail copes with rain and wind. On a 4 x 4 m sail that means around 1.4 m between the high and the low point.

3

Pick a size from the list

If one of the 23 sizes fits, you can order it straight away. If none fits, use the shade sail configurator - there you enter every edge length separately.

4

Choose the finish

If you want to sit under the sail in the rain as well, you need the waterproof finish. For heat and a light breeze, the water-repellent fabric is enough. If in doubt, our Service Center will help.

Frequently asked questions

Frequently Asked Questions

Our shade sail sizes cover 23 ready-made formats: eight squares from 2 x 2 m to 6 x 6 m, nine rectangles from 3 x 4 m to 5 x 6 m and six triangles from 3 x 3 x 3 m to 7 x 7 x 7 m. Each of these sizes comes in three finishes. Anything in between or larger is made to measure.

A small shade sail usually means sizes up to around 3 x 3 m for a balcony, a sandpit or a single seating corner. A large or big shade sail starts at about 20 m² of sail area - so 4 x 5 m, 4.5 x 4.5 m or a 7 x 7 x 7 m triangle. A big shade sail needs stronger fixing points, because more area pulls in the same wind.

Measure the area you want in the shade and add half a metre on each side. A dining table with six chairs takes up around 2.5 x 3.5 m - a 3.5 x 3.5 m or 3 x 5 m sail suits it. For a patio against the house wall, the length of the wall counts: there, 3 x 6 m or 4 x 6 m are the usual sizes. A shade sail 3x3 m covers a dining table for four.

Each corner has a stainless steel D-ring. A snap hook, a turnbuckle and, for longer distances, a rope go in there. The sail is tensioned crosswise and with a clear slope, so that rain runs off and the wind finds no surface to catch. The installation guide for sun shade sails explains this step by step.

On load-bearing points: a house wall with anchors in masonry or concrete, posts set in concrete, a strong tree trunk. Trellises, gutters and carport sheeting cannot take the pull. The distance between two points is always larger than the edge of the sail - add 30 to 50 cm per corner for the snap hook and turnbuckle.

Three things: enough slope (a height difference of 25 to 30 cm per metre across the diagonal), load-bearing fixing points and the right finish. Only the PU-coated Cover fabric with a water column of over 1,500 mm is waterproof; the water-repellent fabrics keep off splashes and short showers. Take any sail down in a storm.

The price depends on area, shape and fabric and is calculated in the configurator as soon as size and finish are set. You do not need to ask for a quote.

Because a sail puts the shade where it is needed, without fixed posts in the middle of the seating area. It can be tensioned at an angle, taken down in autumn and costs a fraction of a fixed roof. When the sun is low, however, the shadow moves to the side - hence the rule of thumb of adding half a metre on each side.

The terms are often mixed up in shops. Waterproofness is a measured value: the water column to UNE EN ISO 20811 tells you what water pressure the fabric withstands. Water resistance only means that a fabric survives getting wet without damage - our water-repellent Agora acrylic is weather-resistant, but it still lets water through in persistent rain. That air permeability is welcome in high summer, because the heat can escape upwards. If you need real protection from rain, choose the waterproof Cover finish.

A 2 x 3 m shade sail is not one of our standard sizes; we make this size to measure. The same applies to any other edge length, to irregular layouts and to trapezoids between the house and a post. You enter the measurements one by one in the shade sail configurator.
