Patio Awning Size Guide

If you are wondering: ‘What size patio awning do I need and how much it is going to cost?’, then look no further! In this guide we’ll explain everything you need to know about awning sizes. Size plays an important part. Width and projection are the main factors to consider, and finding your approximate measurements is simple.

This refers to the length of the wall-mounted bar. To get a rough idea of width, use a tape measure in a horizontal line across the wall. Measure straight across any gutters as if they weren’t there; brackets are available to sit the awning in front of them.

You will see widths are rounded up to the nearest 50cm on our website. This is to make finding an approximate price quicker and easier. Markilux and Weinor actually work to the nearest cm, so it’s possible to be more precise when ordering. This can be very handy for fitting the awning between two walls or other architectural features. Across our range, the largest maximum widths are 700cm for a single patio awning unit. Most awnings we sell are around the 300cm wide mark.

Pairing – for a Larger Width

If you were hoping for a projection wider than 700cm, many awnings can be coupled. This is possible for patio, veranda, freestanding, conservatory and vertical designs.

For example, the Markilux 5010 patio awning can be paired to reach a maximum width of 1390cm, and the Markilux 1650 1410cm. In some instances this can be done seamlessly, with synchronised remote control operation, a junction segment to bridge the gap in the fabric, and sometimes even a single front bar. Some awnings, like the Markilux 1700, allow for three units to be joined in this way.


Projection refers to how far the awning will extend away from the wall. It doesn’t take the pitch into consideration, and measured as if the tape measure is lying flat along the top of the fabric. Projection will be a multiple of 50cm, and less than 400m. The projection often needs to be 500cm less than the width to support the structure effectively, but our team will be able to advise on this. Our most common projection for a patio awning is 250m, but it all depends on how much shading you want to provide. With window awnings, projection is replaced by vertical height.

Markilux 1600 Stretch Arm Technology

Stretch and MiniMax – For a Larger Projection

These patio awnings are Markilux and Weinor’s solutions for spaces which require a larger projection than width. They use special folding arms and other technology to support the weight effectively.

The Markilux 1700 Stretch is an example which offers this flexibility. It is available in projections up to 400cm with a width as small as 225cm.


The required awning pitch will be calculated by your surveyor. It does not affect the price of an awning, but it does affect the amount of shading it can provide. Imagine a level horizontal line from the top of the awning cassette; pitch affects the angle at which the awning cover comes away from this.

Roché recommends a pitch of at least 14° for patio awnings, which is adequate for encouraging rain to run off the surface without compromising too much head height or shading.

The pitch is fixed in place by your installer.
