The thickness of your duvet is typically measured by its tog rating (thermal overall grade), which indicates its warmth level. The tog rating scale ranges from 1 tog (coolest) to 15 tog (warmest).
Choosing the right duvet thickness depends on your personal comfort levels and the season:
Summer: For warmer months, a duvet with a tog rating of 2.5 tog to 4.5 tog is usually sufficient as it provides a lighter cover
Winter: During colder seasons, a higher tog rating between 9 and 13.5 tog is recommended for extra warmth
Year-round: If you're looking for a versatile option that can be used throughout the year, a duvet with a tog rating of 10 to 13.5 is commonly chosen
Contrary to common belief, the tog rating isn't an indicator of a duvet's thickness or quality. Instead, it's a measure to gauge the duvet's capacity to trap warm air. So don't let its numerical value be the sole deciding factor in your purchase. Consider the filling material, weight, and personal preferences for a well-rounded decision.
