Shade Cloth Percentage Explained: How Much Shade Do You Actually Need?

"How much shade do I need?" is the first thing most buyers ask us, and it's the right question — it just doesn't have one clean answer. Shade percentage tells you how much sun a cloth blocks: at 30% most of the light still gets through, at 90% you get deep, cool shade. How much you actually want depends entirely on what's sitting underneath it. A lettuce field and a private balcony are not asking for the same cloth, and picking the wrong shade level is one of the quicker ways to end up with stock that doesn't fit the job you bought it for.
So before you lock a number, work out which way your job leans. Here is how to read shade percentage, match it to the use, and where the figure stops being something you can pick off a chart.
What shade percentage actually means
Shade percentage is the share of sunlight the cloth blocks — no more complicated than that. Our shade cloth runs from about 30% to 90% shade: light, open mesh at one end, dense courtyard cloth at the other.
The number is softer than it looks, though. Two cloths both sold as "70%" won't always feel the same — knit pattern, tape width and colour each move the real shade rate. That's why we confirm the exact percentage against your spec instead of reading it off a table, and why a supplier who quotes you a precise shade figure sight unseen is rounding. Treat the percentage as the feel you're after, not a number good to the decimal.
More shade isn't "better" — match it to the job
The common mistake is to over-spec shade, on the idea that more must be safer. For anything growing, that backfires. Plants need light to grow; the cloth is there to take the heat and sun stress off them, not to shut the sun out. Push the shade too high over a crop and you starve it. Go too low over a carport and the cars still bake underneath. The right level is the one that suits what's below it — roughly, the common uses line up like this:
| Use | Shade level | What you're really after |
|---|---|---|
| Sun-loving crops, field growing, where light and airflow matter most | Low | take the edge off heat without starving the plants |
| Nurseries, shade-tolerant plants, greenhouse tempering, livestock shade | Medium | a balance of light and cooling |
| Carports, patios, pools, outdoor comfort | High | real cooling and glare control for people and vehicles |
| Privacy screens, courtyards, balconies, decorative | High | block the view and throw deep shade |
General guidance — the exact shade % is confirmed per spec, since construction, colour and knit all move it. Our standard dark-green and black courtyard cloth is made at 90% shade, about as dense as shade cloth gets.
Colour changes the shade, not just the look
Colour isn't only cosmetic here. On the same construction, darker cloth — black, dark green — generally blocks more light and soaks up more heat, while lighter and reflective options like aluminet silver handle heat a different way again. So when you choose a colour you're also nudging the shade and how the cloth behaves in full sun. Decide the two together rather than treating colour as an afterthought.
Once you know the shade, GSM is how you order it
Shade percentage is the feel you want; GSM — the weight of the cloth — is the spec we actually set to get there. The two travel together, but they aren't the same lever, and for a bulk order GSM is what pins down the shade, the durability and the cost. If you've landed on roughly how much shade you need, our shade cloth GSM guide walks through choosing the weight to match. Or just tell us the use and the shade level you're after, and we'll point you to the GSM.
Getting it quoted
Tell us what you're shading and the shade level you want — field, greenhouse, carport, courtyard — along with width, length, colour and quantity. We'll confirm the cloth, the GSM, the exact shade % and the material (standard PE or upgraded HDPE) against your spec, and quote FOB, CIF or EXW from Qingdao or Tianjin. MOQ moves with the spec, and we confirm it with the quote.

Tell us what you're shading and we'll spec the cloth
Send the use, the shade level you're after, plus width, length, colour and quantity, and we'll confirm the cloth, GSM, exact shade % and material, with an FOB, CIF or EXW quote.
