This can be verified by the following simple demonstration :

\hsize = 200 true pt
\vsize = 100 true pt
\let \Shipout = \shipout
\def \shipout #1#2{\setbox 0 = #1 {#2}\showbox 0 \Shipout #1 {#2}}
\hbox {}

which yields (in the log file)

 > \box 0 = \vbox (124.0 + 0.0) x 200.0

(spaces interpolated for ease of reading).
