The traditional furoshiki wrapping cloth sizes are 50cm (19 inches) and 70cm (27 inches). These sizes are the traditional hard-working all-rounders that can be used to create a carry bag, wrap gifts or used as a bento wrap for your lunch.
We figured hundreds of years of use is a pretty good indicator of useful sizes so we based our original range on these sizes. Through trial and error we landed on two most popular sizes - the medium (45 cm) and the small (30cm). We added ribbons as it just adds a beautiful finish to the gift and frankly a lovely feeling to the whole process of wrapping the gift.
The medium gift wrap can be used to wrap several books, a pot plant, a wine bottle (albeit our wine bottle bags are a simpler alternative) or a small box. The small is perfect for jewellery, accessories or a small box of chocolate.
For lunches we use cotton vintage scarves that around around the 50cm mark. They are the perfect size to go around a normal lunch box without being too bulky. And double as a zero-waste napkin too. It certainly makes it easy to find one's lunch box in the office-fridge melee too.
Here's some lovely examples of various sizes of furoshiki in use.
