Leather machines ranked by rated max thickness

Rows are ranked by the total thickness the maker says the machine will sew. Where a maker gives no thickness, the presser foot lift is shown instead and the row drops to the bottom.

Spread on this number: 7/8 in (22 mm) (Techsew 5100-SE) down to 16 oz or 1/4 in of leather (Sailrite Leatherwork).

Ounce ratings and inch ratings are kept as printed. This site does not convert one into the other. A dash in the first column means the ranking number is missing or held back for that row.
