This paper deals with the curvilinear parts of Lao motifs, decorative arts that are usually used at decorations of Lao traditional monastic architecture. Referring to the Roundness Method, the paper examines six samples of curvilinear parts of Lao motifs in comparison with those of Thai, which is said to be very similar to Lao motifs. The analysis yields that
- the inner location of Karn Lai components in the Lao motif is more round or blended than that of Thai. However, the roundness feature at the other locations of Karn Lai in Lao motifs are hardly differing from those of Thai.
- In all locations of Bark Lai motifs the curvature of curvilinear lines of Lao is hardly differing from those of Thai.
- In the upper location of Nhod Lai motifs the curvature of curvilinear lines of Lao is more round than that of Thai. In the other locations of Nhod Lai motifs the curvature of curvilinear lines of Lao is hardly differing from those of Thai.
According to these results, most of the curvilinear lines in Lao motifs are considerably more round that those of Thai.

Keywords: Curvature, roundness, Lao motifs.
