Fit the mat to the tray and the product
A mesh liner leaves an airflow path beneath the product. That makes it useful when the underside needs ventilation and the item is firm enough to stay above the chosen openings.
For dough or other soft material, the opening and support beneath the mat matter as much as the outside dimensions. A finer mesh reduces the unsupported span. A solid liner is the appropriate alternative when batter, drips or small particles must be contained.
