Why GSM Matters in Bath Towels: 400 vs 500 vs 600 Explained
GSM measures fabric weight and is a great quick indicator of a towel's heft and absorbency. This guide breaks down common GSM ranges and which suits your needs.
GSM explained
GSM stands for grams per square metre. Higher GSM usually means thicker, heavier towels but also longer drying time. Lower GSM towels dry faster and are lighter.
How GSM interacts with fibre & weave
GSM is not the only factor — fibre type and weave matter too. A 450 GSM bamboo towel can feel different from a 450 GSM cotton towel due to fibre diameter and yarn twist.
