Question

What is the difference between 15pt and 100# paper thickness for folded postcards?

Answer

Paper is measured two different ways, and 15 pt and 100# describe thickness and weight on separate scales, which is exactly why they are easy to confuse.

Measurement	What it means	Typical feel
Points (pt), e.g. 15 pt	The physical thickness of the sheet, in thousandths of an inch	A firmer, more rigid card
Pounds (#), e.g. 100#	The basis weight of the paper for a set ream size	Often a text weight closer to a heavy flyer

A point value like 15 pt cover measures thickness directly, so a higher number means a thicker, stiffer card.
A pound value like 100# text measures weight, and a text weight folds more easily than a stiff cover stock.
For folded pieces, thinner text weights fold cleanly, while thick cover stocks may need scoring to fold without cracking.
Match the stock to the look you want: heavier cover for a premium, rigid feel, or lighter text for easy folding.
