In the context of tartans, thread counts are used not for determining coarseness, but rather for recording and reliably repeating the cross-striped pattern of the cloth. Such a thread count (which for the typical worsted woollen cloth used for a kilt must in total be divisible by 4) is typically given as a series of color-code and thread-count pairs. Sometimes, with typical symmetrical (reflective) tartans, slash () markup at the ends is used to indicate whether (and how much of) a "pivot" colour is to be repeated when the design is mirrored and repeated backwards. For example, calls for a pattern of (left to right) blue, white, blue, red, black, green, and white, and indicates that when mirrored the two white threads (going one direction) or 24 blue threads (going the other) are repeated after mirroring, resulting in a total of 4 white going rightward and 48 blue heading left. This is known as a "half-count at pivot" thread count. The same sett (technically a half-sett) could also be represented , in a "full-count at pivot" thread count; this indicates that after the four white threads, the pattern resumes backwards with 24 green without repetition of any of the white count. The old style, without slash markup – – is considered ambiguous, but is most often interpreted as a full count. The comparatively rare non-symmetrical tartans are given in full setts and are simply repeated without mirroring.
