Understanding Different Weights of Japanese Washi / Paper
Selecting a Japanese paper can be confusing and the biggest source of that confusion is understanding weights.
Washi weights are expressed as GSM — the Metric Standard when comparing the weights of papers. You will see references such as 21g / 50g / etc.
3.7g — 9g is very lightweight tissue primarily used for conservation and repair / very transparent
10g — 25g is light weight, strong and translucent
25g — 45g is the average weight of many Japanese papers with some translucency and great strength
45g — 70g is more opaque with good body, and while the feel is very different, is the approximate weight of Western bond paper
There are not too many Japanese papers over 75g
