What is the difference between 4x4 ,5x5 and 6x6 lace? The difference is the coverage each size gives. 4x4 would of course give you the least coverage, but it is still good for those who like to keep it simple and don’t want much versatility. 5x5 and 6x6 would give you more coverage than the 4x4 and would allow you to be more versatile with parting and styling.

What is the difference between 13x4 and 13x6 lace? Like closures, one gives more parting space and versatility than the other. Lace is from ear to ear on both 13x4 and 13x6, but the 13x6 allows 2 extra inches for parting and styling.
