What the oz weight on a landscape fabric thickness chart means
This landscape fabric thickness chart starts from one fact: fabric is rated by weight in ounces per square yard, and that single number tells you more than any label. A higher oz weight generally means a denser, stronger fabric, but heavier is not automatically better. The right weight is the one that matches the job, whether that is weed control in a bed, load-bearing separation under pavers, or drainage behind a wall. This guide is for landscapers, hardscape crews, growers, and drainage contractors who need to spec the right weight the first time.

Woven weight and non-woven weight are not the same thing
One trap with any thickness chart is comparing weights across fabric types as if they mean the same thing. They do not. In a woven fabric, the weight reflects tightly crossed polypropylene tapes built for weed suppression and load-bearing separation. In a non-woven geotextile, the weight reflects a felted mat of fibers built to filter and let water pass through. A 5 oz woven fabric and a 5 oz non-woven fabric are engineered for different jobs, so do not read across the two as if a number alone settles it. Read the weight inside the right type for the job in front of you.
How to pick a weight from the chart
Work the chart in two steps. First, name the job: weed control, load-bearing separation, or drainage. That picks the type, woven for weeds and load, non-woven for water. Second, pick the weight within that type by how demanding the job is. For weed control in beds and rows, 3.2 oz woven DOTDAY SHIELD is right. For gravel, pavers, and driveways that carry load, step up to 5 oz woven dual-layer XBAR. For drainage, choose non-woven TERRA from 4 to 8 oz by how hard the water and soil are working the fabric.

Three fabrics, three ground conditions
Recommended by the job in front of you, not the price on the shelf. SHIELD is built for garden beds, mulch, farm rows, and nurseries where the job is suppressing weeds. XBAR is the right call under pavers, gravel, and hardscape that takes foot and vehicle traffic. TERRA is built for French drains, retaining-wall backfill, and wet or soft soil where water has to move. Match the weight to the ground, and the fabric lasts.
