Diameter yang terlalu kecil menyebabkan daya putus yang tidak mencukupi, mengakibatkan wayar putus atau patah tali, yang boleh menyebabkan beban jatuh, kerosakan peralatan dan kemalangan keselamatan diri. Walau bagaimanapun, diameter yang terlalu besar meningkatkan beban pada dram, berkas dan mekanisme pengangkat, meningkatkan kos perolehan peralatan dan memburukkan lagi risiko haus mekanisme.
