hi,can anyone tell me the thickness of paper, eg 90gsm?

thanks for help offered, bobbyalec

If you google 'how thick is 90 gsm paper' you'll get all the information you need about paper weights and thicknesses.

Measuring the thickness of paper is a refined art and only possible on Nanometres.

So, what they do is to measure the weight of a 1 square meter sheet.

or you could have a look at this Paper Thickness

Very crude,but for normal purposes good enough. Make stack of say 100 sheets ,place a weight on it

Measure the height(thickness)

Too describe more fully.

The weight compresses the stack to exclude air.

Measure in mm. ÷ by 100 result 0.00x mm.

Why do you need to know? For most purposes the stated weight is a good guide, the higher the weight the thicker the paper. If the thickness is really important the only way is to use a Micrometer to measure it.

BT: Even a Micrometer is not necessarily useful, as the surface of paper is not sufficiently rigid to give a definitive reading.

My solution to 'guess' thickness of a single piece(any area) is the only practical non scientific method.

I suggested 100 Sheets a full ream(500 pieces)will be more accurate

It says in wee eddies link 90gsm is 0.0048inch thick unless I have misunderstood it.

0.0048 inch huh! What's that in metric( mm)?
