A portable dance floor for use on a stationary floor surface is formed of a plurality of like elements each comprising vertically spaced upper and lower similar rectangular panels having straight edges, and at least an upper and a lower set of parallel and spaced-apart sticks. The upper set is fixed to the upper panel and to the lower set and the lower set is fixed to the lower panel. In addition the sticks of the upper set are generally perpendicular to those of the lower set and both sets include two edge sticks at and generally parallel to respective opposite edges of the panels. The sticks of different elements are connected together with the respective upper panels substantially coplanar. Each set of sticks is of a predetermined thickness and extends at a small acute angle to the respective edges so that each edge stick has one end immediately juxtaposed with the respective panel edge and an opposite end spaced inward therefrom by a distance equal generally to its thickness. Thus the tangent of the angle formed between each stick and the panel edges it is generally parallel to is equal to the stick thickness divided by the length of the respective panel edge.
