Paperboard thickness is commonly measured in caliper, expressed in thousandths of an inch. One point equals .001", so a board measuring .060" thick is commonly referred to as 60-point board.
But what does .060" or .080" actually look and feel like?
Common U.S. coins provide an easy reference:
| U.S. Coin | Thickness | Approximate Caliper |
|---|---|---|
| Dime | .053" | 53 pt |
| Penny | .060" | 60 pt |
| Quarter | .069" | 69 pt |
| Nickel | .077" | 77 pt |
| $1 Coin | .079" | 79 pt |
| Half Dollar | .085" | 85 pt |
For example, 60-point paperboard is approximately the thickness of a penny, while 80-point paperboard is roughly the thickness of a nickel or dollar coin.
These comparisons are intended as a convenient visual reference. Paperboard is a fiber-based material, and actual thickness should be specified and measured according to the requirements and tolerances of the particular board grade.
Understanding Paperboard Caliper
Caliper is only one factor when selecting paperboard. Two boards with the same nominal thickness can have different characteristics depending on their construction, density, fiber composition and intended application.
When specifying paperboard, consider caliper, rigidity, surface characteristics, finished size, converting requirements and end use rather than thickness alone.
Lamitech supplies and converts paperboard in a wide range of calipers and constructions for mounting, packaging, displays, printing and specialty applications.
