GSM (grams per square metre) measures towel density. Higher isn't always better - it depends on your needs.
GSM Categories
| Category | GSM Range | Feel |
|---|---|---|
| Light | 300-400 | Thin, quick-dry |
| Medium | 400-550 | Balanced |
| Heavy | 550-700 | Thick, plush |
| Luxury | 700+ | Spa-like |

Medium GSM (450-550)
The practical middle ground:

- Moderate drying time
- Good balance of properties
- Suits most households
This is what most "standard" towels are.
Climate Considerations
Hot/Humid Climate
Lower GSM (400-500) is practical:
- Dries faster (critical in humidity)
- Won't stay damp
- Less mildew risk
- Still absorbent enough
Cold/Dry Climate
Higher GSM (600+) works well:
- Warmth when exiting bath
- Humidity less of a concern
- Plushness appreciated
Direct Comparison
| Factor | Low GSM | High GSM |
|---|---|---|
| Absorbency | Adequate | Excellent |
| Drying time | Fast | Slow |
| Weight | Light | Heavy |
| Storage space | Minimal | Significant |
| Cost | Lower | Higher |
| Luxuriousness | Basic | Premium |
| Practicality | High | Moderate |
Our Recommendation
Most households: 500-600 GSM offers the best balance.
Prioritise quick drying: 400-500 GSM.
Prioritise luxury: 650+ GSM.
Don't assume higher is always better. A 700 GSM towel that never dries properly is worse than a 450 GSM towel that's always fresh.
