That's about the same as a siding nail (8d).

What it means

How long is that nail?

Lengths for common nails; the gauge (thickness) varies by type: common, box, sinker and finish nails of the same penny size differ in diameter.

The math

How to convert d to in

From 2d to 10d, length (in) = penny ÷ 4 + ½; larger sizes follow the table: 16d = 3½ in, 20d = 4 in, 60d = 6 in.

Example: 8d d = 2 1/2 in.
