Not sure what size label fits your mason jar? Start with the smooth, flat area—not just the jar’s advertised capacity.
Common starting points include 2.5-inch round labels for regular-mouth lids, 3-inch round labels for wide-mouth lids, and 2 × 3-inch or 2 × 4-inch labels for jar fronts. Always measure the usable area and test at actual size before ordering.
