outdoor fabric weight
Choosing the right outdoor fabric weight can be the difference between cushions that hold their shape for seasons and covers that sag after a single summer. Weight is usually listed in ounces per square yard or as fabric GSM. It tells you how dense and sturdy a fabric is. It also shapes how your finished project drapes, wears and stands up to wind and sun.
How to Match Outdoor Fabric Weight to Your Project
Heavier isn't always better. The best choice depends on the job the fabric needs to do.
Lightweight Outdoor Fabric
Thinner, more flexible fabrics drape easily. They are a good fit for outdoor curtains, umbrellas and table linens, where soft movement matters more than toughness.
Medium to Heavyweight Outdoor Canvas
Denser canvas and outdoor upholstery fabric stand up to daily sitting and frequent handling. That makes them well suited to seat cushions, throw pillows and chair slings.
Heavy-Duty Covers and Marine Canvas
The heaviest weights resist abrasion and tension. Reach for them when making awnings, boat covers and grill covers.
What Else to Check Before You Buy
- Fiber content and UV resistance
- Water repellency versus true waterproofing
- Whether your sewing machine can handle thicker layers
