I wrote to the makers of Stonehenge paper when we had a customer question.
The were quite helpful 🙂
Q- There is some confusion about the weight of your paper. Retailers seem to have a variety of conversions for the 250gsm to pounds. Can you please tell me the weight of the Stonehenge paper in pounds?
A- A 22×30 sheet of 250gsm paper can be translated into a variety of weight terms, which all correspond to the same basis weight (depending on the ‘language’ used). For example, a 250gsm sheet of Stonehenge is all of the following:
169lb text
92lb cover
138lb index
154lb tag

Jackson’s has decided to avoid the confusion and stick with the GSM that is used by the maker of the paper and not use the pounds at all.
ps – gsm is Grams per Square Metre. So it is specific in itself, without any qualifier words.
Here is the Stonehenge paper on the Jackson’s site. This paper has many uses and is particularly suited to coloured pencil drawings. It comes in a variety of neutral colours in 2 sizes of sheets, a roll and pads. We stock two colours in large sheets until we run out – they are 320gsm.
