Is 80 gms printer paper getting thinner - or am I just imagining it!
Certainly getting more expensive

0.1mm per sheet - a good way to count it is to use a micrometer.


There's a hole in my bucket dear birdbrain, dear birdbrain. The OP was
complaining about the variable thickness of 80gsm paper which suggests
the density of the sheets - and hence the thickness - is variable.

A better way to 'count' sheets would be to weigh them. Each A4 sheet
occupies an area of 0.06237m2 (297 x 210mm). Therefore 16.0333493666827
sheets per m2. Each sheet must always weigh 0.200416867083534 grams
regardless of thickness (otherwise it is not 80gsm paper).

Ooops pressed go too soon.

Each sheet must always weigh 4.9896 grams
regardless of thickness (otherwise it is not 80gsm paper).
