The invention discloses an inside diameter measuring device of a lattice apron in compact spinning and relates to the field of new spinning technology, in particular to a simple and convenient device for measuring the inside diameter of a key component in compact spinning-a lattice apron. The structure thereof comprises two semicircular shells (3) of upper and lower, two elastic tapelines (2) with scale, a tapeline mandrel (4) and the lattice apron (1) which is sheathed on the two semicircular shells (3). The device is designed according to the characteristics of the lattice apron (1) taking the shape of a circularity so as to solve the problem of measuring the inside diameter of the lattice apron (1) and bring convenience to the production and research of the lattice apron (1). The principle of the device is that: the sum of the perimeters of the two semicircular shells (3) contacted with the lattice apron (1) and the scale at two sides is equal to the perimeter of the inside diameter of the lattice apron (1
