Enter GSM to see equivalent basis weight across Bond, Text, Cover, Bristol, Tag, and Index. Use for specs and procurement.
Enter a GSM value. The calculator shows the equivalent basis weight for Bond, Text, Cover, Bristol, Tag, and Index in one view, so you can compare specs across grades.
Each row is the US basis weight (lb per ream at that grade's standard size) for the GSM you entered. Use this to match metric specs to North American grade names when sourcing or specifying paper.
Confusing grades (e.g. 80 lb Text vs 80 lb Cover) leads to wrong paper: they are different thicknesses. Don't assume the same number means the same paper across grades.
