Does thicker stitching on a mousepad guarantee better durability?

No, thicker stitching alone doesn’t guarantee durability. The quality of the stitching matters more than thickness. A tight, consistent overlock stitch or double-stitched hem lasts longer than a thick but sloppy stitch with loose tension. Brands like Steelseries QcK and Razer Gigantus use good overlock edges, while cheap pads with single zigzag stitching fray quickly regardless of thread thickness.
