3x4 frontal vs 13x6
Its pretty simple and straight forwards... both the 13x4 and 13x6 lace fronts can come in the form of alace front closure or a lace front wig. The lace size of the 13x4 lace front wig is 13 inches length by 4 inches width and the 13x6 lace front is 13 inches long by 6 inches width.
The size will all depend on your head size or preference. The 13x6 lace front wig is 2 inches bigger at back than the 13x4, so this gives your closure/wig more breathability. The more lace, the more breathability there will be. So the breathability of the 13x6 is better than the 13x4.
