North American paper weights in lbs to gsm

Posted Tuesday August 30th, 2016

Sometimes we are asked by US or Canadian customers to quote a job for printing in the UK and they give us the weights in pounds. I have one now which is 80lb Silk cover and 100lb Silk text.

Without looking too carefully at what these mean I recommend a web site with a really easy conversion too:

Thank you OK paper.

I like that the site does not give an explanation for why 80lb cover = 220gsm and 100lb text = 150gsm as it must have evolved that way somehow.
